with Self-Programming Function
● LCD Driver (96 SEG × 32 COM)
● Serial Interface with IrDA1.0
DESCRIPTION
The S1C8F626 is a microcomputer which has a built-in 8-bit CPU S1C88 (MODEL3) as the core CPU, 48K-byte
and 192K-byte Flash EEPROMs, 8K byte RAM, 16-bit programmable timers (PWM), serial interface, watchdog
timer, stopwatch timer, an LCD driver that can drive a maximum 96 segments x 32 commons and a supply
voltage detection circuit.
This microcomputer features low-voltage (1.8V) and high-speed (8.2 MHz) operations as well as low-current
consumption (2.5 μA in HALT mode).
Furthermore, the S1C8F626 allows the user to program (erase, program, verify) the internal ROM even if it is
mounted on the target board. The S1C8F626 Flash EEPROM can be used for storing a 11 x 12-dot kanji font
data that contains JIS level-1 and level-2 kanji sets, other characters and user defined characters, this makes it
possible to display kanji characters without any external kanji font ROM.
The S1C8F626 is suitable for various battery driven controllers.
