S1C17W03/W04
(rev1.0)
16-bit Single Chip Microcontroller
● Low voltage operation from 1.2 V with a single alkaline or silver oxide
button battery.
● Ultra low standby power consumption (0.3 µA during HALT state in
super economy mode)
● Embedded A/D converter to support various sensing applications
■ DESCRIPTIONS
The S1C17W03/W04 is a 16-bit MCU that features low-voltage operation from 1.2 V even though Flash memory is included. The embedded high-efficiency DC-DC converter generates the constant-voltage to drive the IC with lower power consumption than 4-bit MCUs. This IC includes a real-time clock, a stopwatch, an A/D converter, and a PWM timer
capable of being used to generate drive waveforms for a motor driver as well as a high-performance 16-bit CPU. It is
suitable for battery-driven applications that require an A/D conversion function and timers.

32-pin
Assigned signal: The signal listed at the top of each pin is assigned in the initial state. The pin function must be
switched via software to assign another signal (see the “I/O Ports” chapter).
I/O:
I
= Input
O
= Output
I/O
= Input/output
P
= Power supply
A
= Analog signal
Hi-Z
= High impedance state
Initial state:
I (Pull-up)
= Input with pulled up
I (Pull-down) = Input with pulled down
Hi-Z
= High impedance state
O (H)
= High level output
O (L)
= Low level output
Tolerant fail-safe structure:
✓
= Over voltage tolerant fail-safe type I/O cell included (see the “I/O Ports” chapter)
The over voltage tolerant fail-safe type I/O cell allows interfacing without passing unnecessary current even if a voltage exceeding VDD is applied to the port. Also unnecessary current is not consumed when the port is externally biased without supplying VDD.
