描述 Description

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-600-2.54): (Product name: MSM82C53-2RS)
• 28-pin Plastic QFJ (QFJ28-P-S450-1.27): (Product name: MSM82C53-2JS)
• 32-pin Plastic SSOP(SSOP32-P-430-1.00-K): (Product name: MSM82C53-2GS-K)
