Product Overview
Samsung KS82C54-10CP CMOS programmable interval timer designed for accurate time delays and event counting in microprocessor-based systems. Direct functional equivalent to industry-standard 8254 and 82C54 devices. Features three independent 16-bit presettable counters capable of clock rates up to 10 MHz across six software-programmable modes. Housed in a standard 24-pin dual inline package (DIP-24) suitable for breadboarding or direct socket replacement in vintage hardware.
Key Features
- Three independent 16-bit programmable timer and counter channels
- 10 MHz maximum input clock frequency
- Six programmable operating modes including rate generator, square wave, and software-triggered strobe
- Binary or BCD counting formats
- 5 V nominal supply voltage with TTL-compatible inputs and outputs
- Standard 24-lead plastic dual inline package (PDIP-24) through-hole design
Applications
- Restoring vintage x86 PC motherboards, industrial single-board computers, and legacy arcade boards
- Generating precise baud rates, system clocks, and real-time interrupts in retrocomputing builds
- Counting external hardware events and frequency intervals in custom microprocessor projects
Frequently Asked Questions
Is the KS82C54-10CP pin-compatible with standard 8254 timers?
Yes. It follows the standard 82C54 architecture and 24-pin DIP pinout, providing low-power CMOS operation and timing capability up to 10 MHz.
What operating modes can be configured on the counters?
Each of the three channels supports six modes: interrupt on terminal count, hardware retriggerable one-shot, rate generator, square wave generator, software triggered strobe, and hardware triggered strobe.
Why purchase an individual timer IC instead of an unverified bulk pull lot?
You receive the exact, clean, individually inspected component pictured on this card rather than taking chances on a mixed lot. Shipping is $8 flat rate, free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
A steady hardware timer from the era when clock cycles were counted one tick at a time. Socket it in, configure your modes, and let the chip keep the beat.
