S1C6P466 TECHNICAL MANUAL EPSON 1
CHAPTER 1: OUTLINE
CHAPTER 1OUTLINE
The S1C6P466 is a microcomputer which has a high-performance 4-bit CPU S1C63000 as the core
CPU, rewritable Flash EEPROM (hereinafter called PROM), RAM, dot-matrix LCD driver, serial interface
and timers. The S1C6P466 has a built-in large capacity PROM (16K × 13 bits) and RAM (5K × 4 bits) that
are compatible with the S1C63454, S1C63458 and S1C63466, it can therefore be used as an MTP (Multi-
Time Programming) for program development.
