DESCRIPTIONS
The S1C17702 is a 16-bit MCU featuring high-speed low-power operations, compact dimensions, wide address space, and
on-chip ICE. Based on an S1C17 CPU core, this product incorporates 128 KB of flash memory, 12 KB of RAM, a serial
interface supporting sensors such as UART, SPI, and I2C to support high-bit rate and IrDA1.0, an 8-bit timer, 16-bit timer,
PWM & capture timer, clock timer, stopwatch timer, watchdog timer, 28 general input/output ports, max. 72 segment x 32
common LCD driver and a power supply voltage booster circuit, power supply voltage detection circuit, 32 kHz and max. 8.2
MHz oscillator circuit, and internal 1.8 V voltage regulator.
It allows 8.2 MHz high-speed operation at an operating voltage of just 1.8 V, and executes single instructions using a single
clock with 16-bit RISC processing. The product also incorporates a coprocessor for arithmetic functions for multiplication and
product-sum operations.
The on-chip ICE function allows onboard programs/deletes of internal flash memory and program debugging and evaluations
following connection of the three signal wires to the ICD Mini (S5U1C17702H).
The S1C17702 is ideal for applications (such as remote controllers and sports watches) requiring battery power and sensor
interface and for LCD displays of up to 72 x 32 dots.
