MSM82CS4FP,-6
CMOS PROGRAMMABLE INTERVAL TIMER
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, count-
operation 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 con-
nected to a TTL circuit.

• Pin connection compatible with M5L8253P-5
• Clock period: M5M82C54FP-6.................. ·.. DC~6MHz
M5M82C54FP ....................... DC~8MHz
• 3 independent bult-in 16-bit down counters
• 6 counter modes freely assignable for each counter
• Binary or decimal counts
• Read-back command for monitoring the count and status
• Package in flat small outline package
APPLICATION
Delayed-time setting, pulse counting and rate generation in
microcomputers.
FUNCTION
Three independent 16-bit counters allow free programming
Outline 24P2W
based on mode-control instructions from the CPU. When
aroughly classified, there are 6 modes (O~5). Mode is main-
ly used as an interruption timer and event counter, mode 1
as a digital one-shot, modes 2 and 3 as rate generators,
mode 4 for a software triggered strobe, and mode 5 for a
hardware triggered strobe.
The count can be monitored and set at any time. Besides
the count, the status of the counter can be monitored by
Read-back command. The counter operates with either the
binary or BCD system.
Refer to M5M82C54P/P-6 for detail information.
M5M82C54FP/FP-6's specification are fully compatible with
M5M82C54P/P-6. Only package outline is different.
