1996 MSM82C53-2RS/GS/JS CMOS PROGRAMMABLE INTERVAL TIMER GENERAL DESCRIPTION The MSM82C53-2RS/GS/JS is programmable universal timers designed for use in microcomputer systems.
Based on silicon gate CMOS technology, it requires a standby current of only 100 mA (max.
) when the chip is in the nonselected state.
During timer operation, power consumption is still very low only 8 mA (max.
) at 8 MHz of current required.
The device consists of three independent counters, and can count up to a maximum of 8 MHz (MSM82C53-2).
The timer features six different counter modes, and binary count/BCD count functions.
Count values can be set in byte or word units, and all functions are freely programmable.
FEATURES • Maximum operating frequency of 8 MHz (MSM82C53-2) • High speed and low power consumption achieved through silicon gate CMOS technology • Completely static operation • Three independent 16-bit down-counters • 3 V to 6 V single power supply • Six counter modes available for each counter • Binary and decimal counting possible • 24-pin Plastic DIP (DIP24-P-600-2.
