Product Summary
The M82C53-2 is a programmable universal timer designed for use in microcomputer systems. Based on silicon gate CMOS technology, the M82C53-2 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 M82C53-2 consists of three independent counters, and can count up to a maximum of 8 MHz. The timer M82C53-2 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.
