GENERAL DESCRIPTION
FEATURES
EM78156E is an 8-bit microprocessor with low-power and high-speed CMOS
technology. Integrated into a single chip are on-chip watchdog timer (WDT), RAM,
ROM, real time clock/counter, external and interrupt, power down mode, and tri-state
I/O.
Operating voltage range : 2.3V~5.5V
Operating temperature range: 0°C~70°C
Operating frequency rang (base on 2 clocks ):

•
1K × 13 bits on chip ROM
One configuration register to accommodate user’s requirements
48× 8 bits on chip registers (SRAM, general purpose register)
2 bi-directional I/O ports
5 level stacks for subroutine nesting
8-bit real time clock/counter (TCC) with selective signal sources, trigger edges, and
overflow interrupt
Two clocks per instruction cycle
Power down (SLEEP) mode
Three available interruptions
