Description and Introduction

Radiation Hardened CMOS Programmable Interval Timer The part **HS1-82C54RH-8** is manufactured by **Intersil**. Here are its specifications based on Ic-phoenix technical data files:

- **Type**: Programmable Interval Timer (PIT)  
- **Model**: 82C54  
- **Package**: RH (likely a hermetically sealed ceramic package)  
- **Speed**: -8 (likely 8 MHz operation)  
- **Function**: Used for timing and event counting in microprocessor systems  
- **Compatibility**: CMOS version of the Intel 8254  

This part is designed for precision timing applications in embedded systems.

Application Scenarios & Design Considerations

Radiation Hardened CMOS Programmable Interval Timer

Alternative Part Number

  • 82C54 --: Original CMOS programmable interval timer that the HS1-82C54RH-8 is based on; same core function and pinout, widely available as the de facto reference part.
  • 82C54-2 --: Harris/Renesas CMOS programmable interval timer in the same 82C54 family with equivalent counter/timer architecture and compatible timing, suitable drop-in functional replacement.
  • 8254 --: Classic NMOS programmable interval timer functionally equivalent to the 82C54, usable where the radiation-hardened HS1 version is not strictly required.
