Notice On Data Sheet Designations
Spansion Inc. issues data sheets with Advance Information or Preliminary designations to advise
readers of product information or intended specifications throughout the product life cycle, includ-
ing development, qualification, initial production, and full production. In all cases, however, readers
are encouraged to verify that they have the latest information before finalizing their design. The
following descriptions of Spansion data sheet designations are presented here to highlight their
presence and definitions.
Advance Information
The Advance Information designation indicates that Spansion Inc. is developing one or more specific
products, but has not committed any design to production. Information presented in a document with
this designation is likely to change, and in some cases, development on the product may discontin-
ue. Spansion Inc. therefore places the following conditions upon Advance Information content:
"This document contains information on one or more products under development at Span-
sion Inc. The information is intended to help you evaluate this product. Do not design in this
product without contacting the factory. Spansion Inc. reserves the right to change or discon-
tinue work on this proposed product without notice."
Preliminary
The Preliminary designation indicates that the product development has progressed such that a
commitment to production has taken place. This designation covers several aspects of the product
life cycle, including product qualification, initial production, and the subsequent phases in the man-
ufacturing process that occur before full production is achieved. Changes to the technical specifica-
tions presented in a Preliminary document should be expected while keeping these aspects of
production under consideration. Spansion places the following conditions upon Preliminary content:
"This document states the current technical specifications regarding the Spansion prod-
uct(s) described herein. The Preliminary status of this document indicates that product
qualification has been completed, and that initial production has begun. Due to the phases
of the manufacturing process that require maintaining efficiency and quality, this document
may be revised by subsequent versions or modifications due to changes in technical spec-
ifications."
Combination
Some data sheets contain a combination of products with different designations (Advance Infor-
mation, Preliminary, or Full Production). This type of document distinguishes these products and
their designations wherever necessary, typically on the first page, the ordering information page,
and pages with the DC Characteristics table and the AC Erase and Program table (in the table
notes). The disclaimer on the first page refers the reader to the notice on this page.
Full Production (No Designation on Document)
When a product has been in production for a period of time such that no changes or only nominal
changes are expected, the Preliminary designation is removed from the data sheet. Nominal
changes may include those affecting the number of ordering part numbers available, such as the
addition or deletion of a speed option, temperature range, package type, or VIO range. Changes
may also include those needed to clarify a description or to correct a typographical error or incor-
rect specification. Spansion Inc. applies the following conditions to documents in this category:
"This document states the current technical specifications regarding the Spansion prod-
uct(s) described herein. Spansion Inc. deems the products to have been in sufficient pro-
duction volume such that subsequent versions of this document are not expected to

■DESCRIPTION
The MB3793 is an integrated circuit to monitor power voltage; it incorporates a watchdog timer.
A reset signal is output when the power is cut or falls abruptly. When the power recovers normally after resetting,
a power-on reset signal is output to microprocessor units (MPUs). An internal watchdog timer with two inputs for
system operation diagnosis can provide a fail-safe function for various application systems.
The model number and package code are as shown below.
■FEATURES
• Precise detection of power voltage fall: 2.5%
• Detection voltage with hysteresis
• Low power dispersion: ICC = 27 A (reference)
• Internal dual-input watchdog timer
• Watchdog timer halt function (by inhibition terminal)
• Independently-set watchdog and reset times
• Mask option for detection voltage (4.9 to 2.4 V, 0.1-V steps)
• Two types of packages (SOP-8pin : 2 types)
■APPLICATION
• Arcade Amusement etc.

■BLOCK FUNCTIONS
1. Comp. S
Comp. S is a comparator with hysteresis to compare the reference voltage with a voltage (VS) that is the result
of dividing the power voltage (VCC) by resistors R1 and R2. When VS falls below 1.24 V, a reset signal is output.
This function enables the MB3793 to detect an abnormality within 1 s when the power is cut or falls abruptly.
2. Comp. O
Comp. O is a comparator to control the reset signal (RESET) output and compares the threshold voltage with
the voltage at the CTP terminal for setting the power-on reset hold time. When the voltage at the CTP terminal
exceeds the threshold voltage, resetting is canceled.
3. Reset output buffer
Since the reset (RESET) output buffer has CMOS organization, no pull-up resistor is needed.
4. Pulse generator
The pulse generator generates pulses when the voltage at the CK1 and CK2 input clock terminals changes to
High from Low level (positive-edge trigger) and exceeds the threshold voltage; it sends the clock signal to the
watchdog timer.
5. Watchdog timer
The watchdog timer can monitor two clock pulses. Short-circuit the CK1 and CK2 clock terminals to monitor a
single clock pulse.
6. Inhibition terminal
The inhibition (INH) terminal forces the watchdog timer on/off. When this terminal is High level, the watchdog
timer is stopped.
7. Flip-flop circuit
The flip-flop circuit RSFF1 controls charging and discharging of the power-on reset hold time setting capacity
(CTP). The flip-flop circuit RSFF2 switches the charging accelerator for charging CTP during resetting on/off. This
circuit only functions during resetting and does not function at power-on reset.

Data Sheet
■OPERATION SEQUENCE
The operation sequence is explained by using “■ TIMING DIAGRAM 1. Basic operation (Positive clock pulse)”.
The following item numbers correspond to the numbers in “■ TIMING DIAGRAM 1. Basic operation (Positive
clock pulse)”.
(1) When the power voltage (VCC) reaches about 0.8 V (VCCL), a reset signal is output.
(2) When VCC exceeds the rising-edge detection voltage (VSH), charging of power-on reset hold time setting
capacitance (CTP) is started. VSH is about 4.3 V.
(3) When the voltage at the CTP terminal setting the power-on reset hold time exceeds the threshold voltage
(Vth), resetting is canceled and the voltage at the RESET terminal changes to High level to start charging of
the watchdog timer monitoring time setting capacitance (CTW). Vth is about 3.6 V.
The power-on reset hold time (tPR) can be calculated by the following equation.
tPR (ms) A CTP (F)
Where, A is about 1300.
(4) When the voltage at the CTW terminal setting the monitoring time reaches High level (VH), CTW switches to
discharging from charging. VH is about 1.24 V (reference value).
(5) When clock pulses are input to the CK2 terminal during CTW discharging after clock pulses are input to the
CK1 terminal—positive-edge trigger, CTW switches to charging.
(6) If clock pulse input does not occur at either the CK1 or CK2 clock terminals during the watchdog timer
monitoring time (tWD), the CTW voltage falls below Low level (VL), a reset signal is output, and the voltage at
the RESET terminal changes to Low level. VL is about 0.24 V.
tWD can be calculated from the following equation.
tWD (ms) B CTW (F) + C CTP (F)
Where, B is about 1500. C is about 3; it is much smaller than B.
Hence, when CTP / CTW 10, the calculation can be simplified as follows:
tWD (ms) B CTW (F)
(7) When the voltage of the CTP terminal exceeds Vth again as a result of recharging CTP, resetting is canceled
and the watchdog timer restarts monitoring.
The watchdog timer reset time (tWR) can be calculated by the following equation.
tWR (ms) D CTP (F)
Where, D is about 100.
(8) When VCC falls below the rising-edge detection voltage (VSL), the voltage of the CTP terminal falls and a reset
signal is output, and the voltage at the RESET terminal changes to Low level. VSL is about 4.2 V.
(9) When VCC exceeds VSH, CTP begins charging.
(10)When the voltage of the CTP terminal exceeds Vth, resetting is canceled and the watchdog timer restarts.
(11)When an inhibition signal is input (INH terminal is High level), the watchdog timer is halted forcibly.
In this case, VCC monitoring is continued without the watchdog timer.
The watchdog timer does not function unless this inhibition input is canceled.
(12)When the inhibition input is canceled (INH terminal is Low level), the watchdog timer restarts.
(13)When the VCC voltage falls below VSL after power-off, a reset signal is output.
(14)When the power voltage (VCC) falls below about 0.8 V (VCCL) , a reset signal is released.
Similar operation is also performed for negative clock-pulse input (“■ TIMING DIAGRAM 2. Basic operation
(Negative clock pulse)”).
Short-circuit the clock terminals CK1 and CK2 to monitor a single clock. The basic operation is the same but
the clock pulses are monitored at every other pulse (■ TIMING Diagram 3. Single-clock input monitoring).

■NOTES ON USE
• Take account of common impedance when designing the earth line on a printed wiring board.
• Take measures against static electricity.
- For semiconductors, use antistatic or conductive containers.
- When storing or carrying a printed circuit board after chip mounting, put it in a conductive bag or container.
- The work table, tools and measuring instruments must be grounded.
- The worker must put on a grounding device containing 250 k to 1 M resistors in series.
• Do not apply a negative voltage
- Applying a negative voltage of 0.3 V or less to an LSI may generate a parasitic transistor, resulting in
malfunction.
