general description
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.
features
operating voltage range : 2.3v~5.5v operating temperature range: 0°c~70°c operating frequency rang (base on 2 clocks ): low power consumption:* less then 2.0 ma at 5v/4mhz 1k x 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 two clocks per instruction cycle power down (sleep) mode three available interruptions programmable free running watchdog timer 8 programmable pull-high pins 7 programmable pull-down pins 8 programmable open-drain pins 2 programmable r-option pins package types: 99.9% single instruction cycle commands the transient point of system frequency between hxt and lxt is around 400khz |
