This document includes the
programming specifications for the
following devices:
1.0 OVERVIEW
The PIC16(L)F151X/152X devices can be
programmed using either the high-voltage In-Circuit
Serial Programming™ (ICSP™) method or the low-
voltage ICSP™ method.
1.1 Hardware Requirements
1.1.1 HIGH-VOLTAGE ICSP
PROGRAMMING
In High-Voltage ICSP™ mode, these devices require
two programmable power supplies; one for VDD and
one for the MCLR/VPP pin.
1.1.2 LOW-VOLTAGE ICSP
PROGRAMMING
In Low-Voltage ICSP™ mode, these devices can be
programmed using a single VDD source in the
operating range. The MCLR/VPP pin does not have to
be brought to a different voltage, but can instead be left
at the normal operating voltage.
1.1.2.1 Single-Supply ICSP Programming
The LVP bit in Configuration Word 2 enables single-
supply (low-voltage) ICSP programming. The LVP bit
defaults to a ‘1’ (enabled) from the factory. The LVP bit
may only be programmed to ‘0’ by entering the High-
Voltage ICSP mode, where the MCLR/VPP pin is raised
to VIHH. Once the LVP bit is programmed to a ‘0’, only
the High-Voltage ICSP mode is available and only the
High-Voltage ICSP mode can be used to program the
device.

• PIC16F1519 • PIC16LF1519
• PIC16F1526 • PIC16LF1526
• PIC16F1527 • PIC16LF1527
Note 1: The High-Voltage ICSP mode is always
available, regardless of the state of the
LVP bit, by applying VIHH to the MCLR/
VPP pin.
2: While in Low-Voltage ICSP mode, MCLR
is always enabled, regardless of the
MCLRE bit, and the port pin can no
longer be used as a general purpose
input.

1.2 Pin Utilization
Five pins are needed for ICSP™ programming. The
pins are listed in Ta b l e 1 - 1 and Table 1-2 .

Note 1: The programming high voltage is internally generated. To activate the Program/Verify mode, high voltage needs to be
applied to MCLR input. Since the MCLR is used for a level source, MCLR does not draw any significant current.

3.1 User ID Location
A user may store identification information (user ID) in
four designated locations. The user ID locations are
mapped to 8000h-8003h. Each location is 14 bits in
length. Code protection has no effect on these memory
locations. Each location may be read with code
protection enabled or disabled.
3.2 Device ID
The device ID word is located at 8006h. This location is
read-only and cannot be erased or modified.
Note: MPLAB® IDE only displays the 7 Least
Significant bits (LSb) of each user ID
location, the upper bits are not read. It is
recommended that only the 7 LSbs be
used if MPLAB IDE is the primary tool
used to read these addresses.

4.0 PROGRAM/VERIFY MODE
In Program/Verify mode, the program memory and the
configuration memory can be accessed and
programmed in serial fashion. ICSPDAT and
ICSPCLK are used for the data and the clock,
respectively. All commands and data words are
transmitted LSb first. Data changes on the rising edge
of the ICSPCLK and latched on the falling edge. In
Program/Verify mode both the ICSPDAT and
ICSPCLK are Schmitt Trigger inputs. The sequence
that enters the device into Program/Verify mode
places all other logic into the Reset state. Upon
entering Program/Verify mode, all I/Os are
automatically configured as high-impedance inputs
and the address is cleared.
4.1 High-Voltage Program/Verify Mode
Entry and Exit
There are two different methods of entering Program/
Verify mode via high-voltage:
•VPP – First entry mode
•V
DD – First entry mode
4.1.1 VPP – FIRST ENTRY MODE
To enter Program/Verify mode via the VPP-first method
the following sequence must be followed:
1. Hold ICSPCLK and ICSPDAT low. All other pins
should be unpowered.
2. Raise the voltage on MCLR from 0V to VIHH.
3. Raise the voltage on VDD FROM 0V to the
desired operating voltage.
The VPP-first entry prevents the device from executing
code prior to entering Program/Verify mode. For
example, when Configuration Word 1 has MCLR
disabled (MCLRE = 0), the power-up time is disabled
(PWRTE =0), the internal oscillator is selected
(FOSC =100), and ICSPCLK and ICSPDAT pins are
driven by the user application, the device will execute
code. Since this may prevent entry, VPP-first entry
mode is strongly recommended. See the timing
diagram in Figure 8-2.
4.1.2 VDD – FIRST ENTRY MODE
To enter Program/Verify mode via the VDD-first method
the following sequence must be followed:
1. Hold ICSPCLK and ICSPDAT low.
2. Raise the voltage on VDD from 0V to the desired
operating voltage.
3. Raise the voltage on MCLR from VDD or below
to VIHH.
The VDD-first method is useful when programming the
device when VDD is already applied, for it is not
necessary to disconnect VDD to enter Program/Verify
mode. See the timing diagram in Figure 8-1.
4.1.3 PROGRAM/VERIFY MODE EXIT
To exit Program/Verify mode take MCLR to VDD or
lower (VIL). See Figures 8-3 and 8-4.
4.2 Low-Voltage Programming (LVP)
Mode
The Low-Voltage Programming mode allows the
PIC16(L)F151X/152X devices to be programmed using
VDD only, without high voltage. When the LVP bit of
Configuration Word 2 register is set to ‘1’, the low-
voltage ICSP programming entry is enabled. To disable
the Low-Voltage ICSP mode, the LVP bit must be
programmed to ‘0’. This can only be done while in the
High-Voltage Entry mode.
Entry into the Low-Voltage ICSP Program/Verify modes
requires the following steps:
1. MCLR is brought to VIL.
2. A 32-bit key sequence is presented on
ICSPDAT, while clocking ICSPCLK.
The key sequence is a specific 32-bit pattern, '0100
1101 0100 0011 0100 1000 0101 0000' (more
easily remembered as MCHP in ASCII). The device will
enter Program/Verify mode only if the sequence is
valid. The Least Significant bit of the Least Significant
nibble must be shifted in first.
Once the key sequence is complete, MCLR must be
held at VIL for as long as Program/Verify mode is to be
maintained.
For low-voltage programming timing, see Figure 8-8
and Figure 8-9.
Exiting Program/Verify mode is done by no longer
driving MCLR to VIL. See Figure 8-8 and Figure 8-9.
Note: To enter LVP mode, the LSB of the Least
Significant nibble must be shifted in first.
This differs from entering the key
sequence on other parts.

PIC16(L)F151X/152X
4.3 Program/Verify Commands
The PIC16(L)F151X/152X implements 10
programming commands; each six bits in length. The
commands are summarized in Ta bl e 4 - 1 .
Commands that have data associated with them are
specified to have a minimum delay of TDLY between the
command and the data. After this delay 16 clocks are
required to either clock in or clock out the 14-bit data
word. The first clock is for the Start bit and the last clock
is for the Stop bit.
4.3.1 LOAD CONFIGURATION
The Load Configuration command is used to access
the configuration memory (User ID Locations,
Configuration Words, Calibration Words). The Load
Configuration command sets the address to 8000h and
loads the data latches with one word of data (see
Figure 4-1).
After issuing the Load Configuration command, use the
Increment Address command until the proper address
to be programmed is reached. The address is then pro-
grammed by issuing either the Begin Internally Timed
Programming or Begin Externally Timed Programming
command.
The only way to get back to the program memory
(address 0) is to exit Program/Verify mode or issue the
Reset Address command after the configuration memory
has been accessed by the Load Configuration command.

4.3.2 LOAD DATA FOR PROGRAM
MEMORY
The Load Data for Program Memory command is used
to load one 14-bit word into the data latches. The word
programs into program memory after the Begin
Internally Timed Programming or Begin Externally
Timed Programming command is issued (see
Figure 4-2).
FIGURE 4-2: LOAD DATA FOR PROGRAM MEMORY
4.3.3 READ DATA FROM PROGRAM
MEMORY
The Read Data from Program Memory command will
transmit data bits out of the program memory map
currently accessed, starting with the second rising edge
of the clock input. The ICSPDAT pin will go into Output
mode on the first falling clock edge, and it will revert to
Input mode (high-impedance) after the 16th falling edge
of the clock. If the program memory is code-protected
(CP), the data will be read as zeros (see Figure 4-3).

4.3.4 INCREMENT ADDRESS
The address is incremented when this command is
received. It is not possible to decrement the address.
To reset this counter, the user must use the Reset
Address command or exit Program/Verify mode and re-
enter it. If the address is incremented from address
7FFFh, it will wrap-around to location 0000h. If the
address is incremented from FFFFh, it will wrap-around

4.3.6 BEGIN INTERNALLY TIMED
PROGRAMMING
A Load Configuration or Load Data for Program
Memory command must be given before every Begin
Programming command. Programming of the
addressed memory will begin after this command is
received. An internal timing mechanism executes the
write. The user must allow for the program cycle time,
TPINT, for the programming to complete.
The End Externally Timed Programming command is
not needed when the Begin Internally Timed
Programming is used to start the programming.
The program memory address that is being
programmed is not erased prior to being programmed.

5.0 PROGRAMMING ALGORITHMS
The devices use internal latches to temporarily store
the 14-bit words used for programming. Refer to
Table 4-2 for specific latch information. The data
latches allow the user to write the program words with
a single Begin Externally Timed Programming or Begin
Internally Timed Programming command. The Load
Program Data or the Load Configuration command is
used to load a single data latch. The data latch will hold
the data until the Begin Externally Timed Programming
or Begin Internally Timed Programming command is
given.
The data latches are aligned with the LSbs of the
address. The PC’s address at the time the Begin
Externally Timed Programming or Begin Internally
Timed Programming command is given will determine
which location(s) in memory are written. Writes cannot
cross the physical boundary. For example, with the
PIC16F1527, attempting to write from address 0002h-
0009h will result in data being written to 0008h-000Fh.
If more than the maximum number of data latches are
written without a Begin Externally Timed Programming
or Begin Internally Timed Programming command, the
data in the data latches will be overwritten. The
following figures show the recommended flowcharts for
programming.

6.0 CODE PROTECTION
Code protection is controlled using the CP bit in
Configuration Word 1. When code protection is
enabled, all program memory locations (0000h-7FFFh)
read as all ‘0’. Further programming is disabled for the
program memory (0000h-7FFFh).
The user ID locations and Configuration Words can be
programmed and read out regardless of the code
protection settings.
6.1 Program Memory
Code protection is enabled by programming the CP bit
in Configuration Word 1 register to ‘0’.
The only way to disable code protection is to use the
Bulk Erase Program Memory command.
7.0 HEX FILE USAGE
In the hex file there are two bytes per program word
stored in the Intel® INHX32 hex format. Data is stored
LSB first, MSB second. Because there are two bytes
per word, the addresses in the hex file are 2x the
address in program memory. (Example: Configuration
Word 1 is stored at 8007h on the PIC16(L)F151X/
152X. In the hex file this will be referenced as 1000Eh-
1000Fh).
7.1 Configuration Word
To allow portability of code, it is strongly recommended
that the programmer is able to read the Configuration
Words and user ID locations from the hex file. If the
Configuration Words information was not present in the
hex file, a simple warning message may be issued.
Similarly, while saving a hex file, Configuration Words
and user ID information should be included.
7.2 Device ID and Revision
If a device ID is present in the hex file at 1000Ch-
1000Dh (8006h on the part), the programmer should
verify the device ID (excluding the revision) against the
value read from the part. On a mismatch condition the
programmer should generate a warning message.

7.3 Checksum Computation
The checksum is calculated by two different methods

With the program code protection disabled, the
checksum is computed by reading the contents of the
PIC16(L)F151X/152X program memory locations and
adding up the program memory data starting at address
0000h, up to the maximum user addressable location.
Any Carry bit exceeding 16 bits are ignored.
Additionally, the relevant bits of the Configuration Words
are added to the checksum. All unimplemented
Configuration bits are masked to ‘0’.

= 3D12h
Note 1: Sum of memory addresses = (Total number of program memory address locations) x (3FFFh) = C000h,
truncated to 16 bits.
2: Configuration Word 1 and 2 = all bits are ‘1’; thus, code-protect is disabled.
3: Configuration Word 1 and 2 Mask = all bits are set to ‘1’, except for unimplemented bits that are ‘0’.
PIC16LF1527 Sum of Memory addresses 0000h-3FFFh(1) 4156h
Configuration Word 1(2) 3FFFh
Configuration Word 1 mask(3) 3EFFh
Configuration Word 2(2) 3FFFh
Configuration Word 2 mask(4) 3E03h
Checksum = 4156h + (3FFFh and 3EFFh) + (3FFFh and 3E03h)
= 4156h + 3EFFh + 3E03h
= BE58h
Note 1: Total number of Program memory address locations: 3FFFh + 1 = 4000h. Then, 4000h - 2 = 3FFEh.
Thus, [(3FFEh x 3FFFh) + (2 x 00AAh)] = 4156h, truncated to 16 bits.
2: Configuration Word 1 and 2 = all bits are ‘1’; thus, code-protect is disabled.
3: Configuration Word 1 Mask = all Configuration Word bits are set to ‘1’, except for unimplemented bits
that are ‘0’.
4: On the PIC16LF1527 device, the VCAPEN bit is not implemented in Configuration Word 2; Thus, all
unimplemented bits are ‘0’.

7.3.2 PROGRAM CODE PROTECTION
ENABLED
With the program code protection enabled, the
checksum is computed in the following manner: The
Least Significant nibble of each user ID is used to
create a 16-bit value. The masked value of user ID
location 8000h is the Most Significant nibble. This sum
of user IDs is summed with the Configuration Words (all
unimplemented Configuration bits are masked to ‘0’).
EXAMPLE 7-3: CHECKSUM COMPUTED WITH PROGRAM CODE PROTECTION ENABLED
PIC16F1527, BLANK DEVICE
PIC16F1527 Configuration Word 1(2) 3F7Fh
Configuration Word 1 mask(3) 3EFFh
Configuration Word 2(2) 3FFFh
Configuration Word 2 mask(3) 3E13h
User ID (8000h)(1) 0006h
User ID (8001h)(1) 0007h
User ID (8002h)(1) 0001h
User ID (8003h)(1) 0002h
Sum of User IDs(4) = (0006h and 000Fh) << 12 + (0007h and 000Fh) << 8 +
(0001h and 000Fh) << 4 + (0002h and 000Fh)
= 6000h + 0700h + 0010h + 0002h
= 6712h
Checksum = (3F7Fh and 3EFFh) + (3FFFh and 3E13h) + Sum of User IDs
= 3E7Fh +3713h + 6712h
= DCA4h
Note 1: User ID values in this example are random values.
2: Configuration Word 1 and 2 = all bits are ‘1’ except the code-protect enable bit.
3: Configuration Word 1 and 2 Mask = all Configuration Word bits are set to ‘1’, except for unimplemented
bits which read ‘0’.
4: << = shift left, thus the LSb of the first user ID value is the MSb of the sum of user IDs and so on, until
the LSb of the last user ID value becomes the LSb of the sum of user IDs.

PIC16LF1527, 00AAh AT FIRST AND LAST ADDRESS
PIC16LF1527 Configuration Word 1(2) 3F7Fh
Configuration Word 1 mask(3) 3EFFh
Configuration Word 2(2) 3FFFh

User ID (8000h)(1) 000Eh
User ID (8001h)(1) 0008h
User ID (8002h)(1) 0005h
User ID (8003h)(1) 0008h
Sum of User IDs(4) = (000Eh and 000Fh) << 12 + (0008h and 000Fh) << 8 +
(0005h and 000Fh) << 4 + (0008h and 000Fh)
= E000h + 0800h + 0050h + 0008h
= E858h
Checksum = (3F7Fh and 3EFFh) + (3FFFh and 3E03h) + Sum of User IDs
= 3E7Fh +3E03h + E858h
= 64DAh
Note 1: User ID values in this example are random values.
2: Configuration Word 1 and 2 = all bits are ‘1’ except the code-protect enable bit.
3: Configuration Word 1 and 2 Mask = all Configuration Word bits are set to ‘1’, except for unimplemented
bits which read ‘0’.
4: << = shift left, thus the LSb of the first user ID value is the MSb of the sum of user IDs and so on, until
the LSb of the last user ID value becomes the LSb of the sum of user IDs.
5: On the PIC16LF1527 device, the VCAPEN bit is not implemented in Configuration Word 2; thus, all

Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Microchip received ISO/TS-16949:2009 certification for its worldwide
headquarters, design and wafer fabrication facilities in Chandler and
Tempe, Arizona; Gresham, Oregon and design centers in California
and India. The Company’s quality system processes and procedures
are for its PIC® MCUs and dsPIC® DSCs, KEELOQ® code hopping
devices, Serial EEPROMs, microperipherals, nonvolatile memory and
analog products. In addition, Microchip’s quality system for the design
and manufacture of development systems is ISO 9001:2000 certified.
