SC18IS602B I2C-bus to SPI bridge Rev. 7 -- 21 October 2019 Product data sheet 1. General description The SC18IS602B is designed to serve as an interface between a standard I2C-bus of a microcontroller and an SPI bus. This allows the microcontroller to communicate directly with SPI devices through its I2C-bus. The SC18IS602B operates as an I2C-bus slave-transmitter or slave-receiver and an SPI master. The SC18IS602B controls all the SPI bus-specific sequences, protocol, and timing. The SC18IS602B has its own internal oscillator, and it supports four SPI chip select outputs that may be configured as GPIO when not used. 2.

Functional description The SC18IS602B acts as a bridge between an I2C-bus and an SPI interface. It allows an I2C-bus master device to communicate with any SPI-enabled device. 7.1 I2C-bus interface The I2C-bus uses two wires (SDA and SCL) to transfer information between devices connected to the bus, and it has the following features: * Bidirectional data transfer between masters and slaves * Multi-master bus (no central master) * Arbitration between simultaneously transmitting masters without corruption of serial data on the bus * Serial clock synchronization allows devices with different bit rates to communicate via one serial bus * Serial clock synchronization can be used as a handshake mechanism to suspend and resume serial transfer * The I2C-bus may be used for test and diagnostic purposes A typical I2C-bus configuration is shown in Figure 3.

I2C-bus configuration The SC18IS602B device provides a byte-oriented I2C-bus interface that supports data transfers up to 400 kHz. When the I2C-bus master is reading data from SC18IS602B, the device will be a slave-transmitter. The SC18IS602B will be a slave-receiver when the I2C-bus master is sending data. At no time does the SC18IS602B act as an I2C-bus master, however, it does have the ability to hold the SCL line LOW between bytes to complete its internal processes.

Slave address The first seven bits of the first byte sent after a START condition defines the slave address of the device being accessed on the bus. The eighth bit determines the direction of the message. A `0' in the least significant position of the first byte means that the master will write information to a selected slave. A `1' in this position means that the master will read information from the slave. When an address is sent, each device in a system compares the first seven bits after the START condition with its address. If they match, the device considers itself addressed by the master as a slave-receiver or slave-transmitter, depending on the R/W bit. A slave address of the SC18IS602B is comprised of a fixed and a programmable part. The programmable part of the slave address enables the maximum possible number of such devices to be connected to the I2C-bus. Since the SC18IS602B has three programmable address bits (defined by the A2, A1, and A0 pins), it is possible to have eight of these devices on the same bus. The state of the A2, A1, and A0 pins are latched at reset. Changes made after reset will not alter the address. When SC18IS602B is busy after the address byte is transmitted, it will not acknowledge its address. 7.1.2 Write to data buffer All communications to or from the SC18IS602B occur through the data buffer. The data buffer is 200 bytes deep. A message begins with the SC18IS602B address, followed by the Function ID. Depending upon the Function ID, zero to 200 data bytes can follow. The SC18IS602B will place the data received into a buffer and continue loading the buffer until a STOP condition is received. After the STOP condition is detected, further communications will not be acknowledged until the function designated by the Function ID has been completed.

Write to data buffer 7.1.3 SPI read and write - Function ID 01h to 0Fh Data in the buffer will be sent to the SPI port if the Function ID is 01h to 0Fh. The Function ID contains the Slave Select (SS) to be used for the transmission on the SPI port. There are four Slave Selects that can be used, with each SS being selected by one of the bits in SC18IS602B Product data sheet All information provided in this document is subject to legal disclaimers.

There is no restriction on the number or combination of Slave Selects that can be enabled for an SPI message.

I2C-bus message SPI data DATA n DATA 1 002aac451 Fig 7. SPI message The SC18IS602B counts the number of data bytes sent to the I2C-bus port and will automatically send this same number of bytes to the SPI bus. As the data is transmitted from the MOSI pin, it is also read from the MISO pin and saved in the data buffer. Therefore, the old data in the buffer is overwritten. The data in the buffer can then be read back. If the data from the SPI bus needs to be returned to the I2C-bus master, the process must be completed by reading the data buffer. Section 8 gives an example of an SPI read. 7.1.4 Read from buffer A read from the data buffer requires no Function ID. The slave address with the R/W bit set to a `1' will cause the SC18IS602B to send the buffer contents to the I2C-bus master. The buffer contents are not modified during the read process.

The buffer is undefined after the GPIO data is read back from the buffer. Therefore, reading data from the GPIO always requires a two-message sequence (GPIO Read, followed by Read Buffer). 7.1.10 GPIO Enable - Function ID F6h At reset, the Slave Select pins (SS0, SS1, SS2 and SS3) are configured to be used as slave select outputs. If these pins are not required for the SPI functions, they can be used as GPIO after they are enabled as GPIO. Any combination of pins may be configured to function as GPIO or Slave Selects. After the GPIO Enable function is sent, the ports defined as GPIO will be configured as quasi-bidirectional. S SLAVE ADDRESS W A A F6h DATA A P 002aac456 Fig 14.

These are: quasi-bidirectional, push-pull, open-drain, and input-only. Two configuration bits in GPIO Configuration register for each pin select the type for each pin. A pin has Schmitt-triggered input that also has a glitch suppression circuit. 7.1.11.1 Quasi-bidirectional output configuration Quasi-bidirectional outputs can be used both as an input and output without the need to reconfigure the pin. This is possible because when the pin outputs a logic HIGH, it is weakly driven, allowing an external device to pull the pin LOW. When the pin is driven LOW, it is driven strongly and able to sink a large current. There are three pull-up transistors in the quasi-bidirectional output that serve different purposes. One of these pull-ups, called the `very weak' pull-up, is turned on whenever the port latch for the pin contains a logic 1. This very weak pull-up sources a very small current that will pull the pin HIGH if it is left floating. A second pull-up, called the `weak' pull-up, is turned on when the port latch for the pin contains a logic 1 and the pin itself is also at a logic 1 level. This pull-up provides the primary source current for a quasi-bidirectional pin that is outputting a 1. If this pin is SC18IS602B Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 7 -- 21 October 2019 (c) NXP Semiconductors N.V. 2019. All rights reserved. 10 of 25 SC18IS602B NXP Semiconductors I2C-bus to SPI bridge pulled LOW by an external device, the weak pull-up turns off, and only the very weak pull-up remains on. In order to pull the pin LOW under these conditions, the external device has to sink enough current to overpower the weak pull-up and pull the pin below its input threshold voltage. The third pull-up is referred to as the `strong' pull-up. This pull-up is used to speed up LOW-to-HIGH transitions on a quasi-bidirectional pin when the port latch changes from a logic 0 to a logic 1. When this occurs, the strong pull-up turns on for two CPU clocks quickly pulling the pin HIGH. The quasi-bidirectional pin configuration is shown in Figure 15. Although the SC18IS602B is a 3 V device, most of the pins are 5 V tolerant. If 5 V is applied to a pin configured in quasi-bidirectional mode, there will be a current flowing from the pin to VDD causing extra power consumption. Therefore, applying 5 V to pins configured in quasi-bidirectional mode is discouraged. A quasi-bidirectional pin has a Schmitt-triggered input that also has a glitch suppression circuit. 2 SYSTEM CLOCK CYCLES VDD P strong P very weak P weak GPIO pin pin latch data VSS input data glitch rejection 002aac548 Fig 15. Quasi-bidirectional output configuration 7.1.11.2 Open-drain output configuration The open-drain output configuration turns off all pull-ups and only drives the pull-down transistor of the pin when the port latch contains a logic 0. To be used as a logic output, a pin configured in this manner must have an external pull-up, typically a resistor tied to VDD. The pull-down for this mode is the same as for the quasi-bidirectional mode. The open-drain pin configuration is shown in Figure 16. An open-drain pin has a Schmitt-triggered input that also has a glitch suppression circuit. SC18IS602B Product data sheet All information provided in this document is subject to legal disclaimers.

The SPI interface uses at least four pins: SPICLK, MOSI, MISO, and Slave Select (SSn). SSn are the slave select pins. In a typical configuration, an SPI master selects one SPI device as the current slave. There are actually four SSn pins (SS0, SS1, SS2 and SS3) to allow the SC18IS602B to communicate with multiple SPI devices. The SC18IS602B generates the SPICLK (SPI clock) signal in order to send and receive data. The SCLK, MOSI, and MISO are typically tied together between two or more SPI devices. Data flows from the SC18IS602B (master) to slave on the MOSI pin (Pin 6) and the data flows from slave to SC18IS602B (master) on the MISO pin (Pin 5). 8. I2C-bus to SPI communications example The following example describes a typical sequence of events required to read the contents of an SPI-based EEPROM. This example assumes that the SC18IS602B is configured to respond to address 50h. A START condition is shown as `ST', while a STOP condition is `SP'. The data is presented in hexadecimal format. 1. The first message is used to configure the SPI port for mode and frequency. ST,50,F0,02,SP SPI frequency 115 kHz using Mode 0 2. An SPI EEPROM first requires that a Write Enable command be sent before data can be written. ST,50,04,06,SP EEPROM write enable using SS2, assuming the Write Enable is 06h 3. Clear the interrupt. This is not required if using a polling method rather than interrupts. ST,50,F1,SP Clear interrupt 4. Write the 8 data bytes. The first byte (Function ID) tells the SC18IS602B which Slave Select output to use. This example uses SS2 (shown as 04h). The first byte sent to the EEPROM is normally 02h for the EEPROM write command. The next one or two bytes represent the subaddress in the EEPROM. In this example, a two-byte subaddress is used. Bytes 00 and 30 would cause the EEPROM to write to subaddress 0030h. The next eight bytes are the eight data bytes that will be written to subaddresses 0030h through 0037h. ST,50,04,02,00,30,01,02,03,04,05,06,07,08,SP Write 8 bytes using SS2 5. When an interrupt occurs, do a Clear Interrupt or wait until the SC18IS602B responds to its I2C-bus address.

Note that we are writing a command, even though we are going to perform a read from the SPI port. The Function ID is again 04h, indicating that we are going to use SS2. The EEPROM requires that you send a 03h for a read, followed by the subaddress you would like to read. We are going to read back the same data previously written, so this means that the subaddress should be 0030h. We would like to read back 8 bytes so we can send eight bytes of FFh to tell the SC18IS602B to send eight more bytes on MOSI. While it is sending these eight data bytes, it is also reading the MISO pin and saving the data in the buffer. ST,50,04,03,00,30,FF,FF,FF,FF,FF,FF,FF,FF,SP Read 8 bytes using SS2 7. The interrupt can be cleared, if needed. ST,50,F1,SP Clear interrupt 8. Read back the data buffer. Note that we will actually need to read back 11 data bytes since the first three bytes sent on the SPI port were the read code (03h) and the two subaddress bytes. ST,50,00,00,00,01,02,03,04,05,06,07,08,SP Read the data buffer I2C-bus You can see that on the the first four bytes do not contain the data from the SPI bus. The first byte is the SC18IS602B address, followed by three dummy data bytes. These dummy data bytes correspond to the three bytes sent to the EEPROM before it actually places data on the bus (command 03h, subaddress 0030h). 9. Limiting values Table 12.

A more in-depth account of soldering ICs can be found in Application Note AN10365 "Surface mount reflow soldering description". 13.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 13.2 Wave and reflow soldering Wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. The wave soldering process is suitable for the following: * Through-hole components * Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: * * * * * * Board specifications, including the board finish, solder masks and vias Package footprints, including solder thieves and orientation The moisture sensitivity level of the packages Package placement Inspection and repair Lead-free soldering versus SnPb soldering 13.3 Wave soldering Key characteristics in wave soldering are: * Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave * Solder bath specifications, including temperature and impurities SC18IS602B Product data sheet All information provided in this document is subject to legal disclaimers.

All rights reserved. 19 of 25 SC18IS602B NXP Semiconductors I2C-bus to SPI bridge 13.4 Reflow soldering Key characteristics in reflow soldering are: * Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure 22) than a SnPb process, thus reducing the process window * Solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board * Reflow temperature profile; this profile includes preheat, reflow (in which the board is heated to the peak temperature) and cooling down. It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table 15 and 16 Table 15. SnPb eutectic process (from J-STD-020C) Package thickness (mm) Package reflow temperature (C) Volume (mm3) < 350 350 < 2.5 235 220 2.5 220 220 Table 16.

Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 22.
