概要
Description
Key features:
- Three 16-bit counters: Each can be individually programmed.
- Multiple operating modes: Supports interval timing, frequency division, and pulse generation.
- Clock input up to 8 MHz: Suitable for precision timing applications.
- CMOS technology: Low power consumption and high noise immunity.
Commonly used in embedded systems, industrial control, and real-time applications for accurate timing and event counting. The MD82C54/B is a reliable, industry-standard solution for timing tasks.
Equivalent
- Intel 8254 (original version)
- AMD 8254
- NEC μPD71054
- Harris 82C54
- OKI MSM82C54
These chips are functionally compatible and offer similar features, though minor variations may exist in timing or electrical specs. Always verify datasheets for exact replacements.
Pinout
- Three independent 16-bit counters, each configurable for different modes (e.g., rate generator, square wave, event counter).
- Clock inputs (CLK0-2) for each counter.
- Gate inputs (GATE0-2) to control counting.
- Output pins (OUT0-2) for timer signals.
- Data bus (D0-D7) for communication with the CPU.
- Control signals (CS, RD, WR, A0-A1) for addressing and operation control.
It is commonly used in timing, frequency generation, and event counting applications.
Application
1. Computer Systems – For timing, interrupt generation, and real-time clock functions.
2. Industrial Control – Precision timing in automation and process control.
3. Communication Equipment – Baud rate generation and synchronization.
4. Embedded Systems – Task scheduling and event counting.
5. Test & Measurement – Frequency and pulse-width modulation (PWM) applications.
It features three independent 16-bit counters, making it versatile for various timing tasks.
