M5M82C54FP
M5M82C54FP is CMOS PROGRAMMABLE INTERVAL TIMER manufactured by Mitsubishi Electric.
DESCRIPTION
The M5M82C54FP is a programmable general-purpose timer device developed by using the silicon-gate CMOS process. It offers counter and timer functions in systems using an 8-bit parallel-processing CPU. The use of the M5M82C54FP frees the CPU from the execution of looped programs, countoperation programs and other simple processing involving many repetitive operations, thus contributing to improved system throughputs. The M5M82C54FP works on a single power supply, and both its input and output can be connected to a TTL circuit.
