S1C17554/564

16-bit Single Chip Microcontroller

●

48-pin wafer-chip-scale package (WCSP)

●

10-bit A/D converter

●

Code-efficient architecture optimized for the C language, single-cycle

instruction high processing performance, serial ICE, and built-in 16-bit

RISC PCU core S1C17

■ DESCRIPTIONS

The S1C17554/564 is a compact 16-bit MCU that delivers high-speed, low power operation with large address space and

on-chip ICE. It integrates A/D converter and thus various analog-interface sensors are connectable. The ultra small

power-saving 48-pin WCSP is most suitable for sensor-applied products that require low power consumption and high-speed

processing.
