General Description
JA58560 series is an ROM based 8-bit microcontroller
which employs a full CMOS technology enhanced
with low cost, high speed and high noise immunity.
Watchdog Timer, RAM, ROM, tri-state I/O port,
power down mode, and real time programmable
clock / counter are integrated into this chip. JA58560
contains 33 instructions, all are single cycle except
for program branches which take two cycles.
On chip memory is available with for 1Kx14 bits of
ROM for JA58560 and 25 bytes of static RAM.
