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.
