GENERAL DESCRIPTION
controller which employs a full CMOS technology
enhanced with low-cost, high speed and high noise
immunity. Watchdog Timer, RAM, EPROM, tri-state
I/O port, power down mode, and real time program-
mable clock/counter are integrated into this chip.
MTU8B5X contains 33 instructions, all are single
cycle except for program branches which take two
cycles.
EPROM for MTU8B54E/55E, 1Kx14 bits of EPROM
for MTU8B56E, 2Kx14 bits of EPROM for
MTU8B57E and 24 to 72 bytes of static RAM.
- RC : Low-cost RC oscillator
- XTAL : Standard crystal oscillator
- HFXTAL : High frequency crystal oscillator
- LFXTAL : Low frequency crystal oscillator
