Description and Introduction

1024 x 1 CMOS RAM The part HM1-6508B/883 is a high-reliability (Hi-Rel) military-grade integrated circuit manufactured by Intersil (now part of Renesas Electronics). Key specifications include:  

- **Type**: Radiation-hardened, 16-bit microprocessor  
- **Technology**: CMOS/SOS (Silicon-on-Sapphire)  
- **Operating Temperature Range**: -55°C to +125°C  
- **Supply Voltage**: 5V ±10%  
- **Package**: 40-pin ceramic DIP (Dual In-line Package)  
- **Qualification**: MIL-PRF-38535 Class V (space and high-reliability applications)  
- **Radiation Hardness**:  
  - Total Dose: ≥ 100 krad(Si)  
  - SEL (Single Event Latchup) Immune  
  - SEU (Single Event Upset) Tolerant  

This part is designed for aerospace, defense, and other mission-critical applications requiring high reliability in harsh environments.

Application Scenarios & Design Considerations

1024 x 1 CMOS RAM

Alternative Part Number

  • CY7C168A-35PC --: A 4K x 4 static RAM in a DIP package with similar organization and access time, widely used as a functional replacement for the HM1-6508 series in legacy designs.
  • AM2168-35PC --: A 4K x 4 SRAM with comparable speed and pinout, commonly cross-referenced for Harris/Intersil 6508-type memory devices in military and industrial systems.
  • IDT6116SA35P --: A well-known 2K x 8 SRAM that can serve as an alternative memory solution when board-level rework is acceptable, offering similar access time and DIP packaging.
