Description and Introduction

131,072-word X 8-bit High Speed CMOS Static RAM The part **HM628128ALR-8** is a **128K x 8-bit Low Power CMOS Static RAM (SRAM)** manufactured by **Hitachi (now Renesas Electronics)**.  

### **Key Specifications:**  
- **Organization:** 128K × 8-bit  
- **Technology:** Low Power CMOS  
- **Operating Voltage:** 3.3V  
- **Access Time:** 8 ns (indicated by "-8" in the part number)  
- **Package:** 32-pin SOP (Small Outline Package) or similar  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Standby Current:** Low power consumption in standby mode  
- **I/O Interface:** 8-bit parallel  

This SRAM is designed for high-speed, low-power applications such as embedded systems, networking, and industrial electronics.  

(Note: Exact specifications may vary slightly depending on datasheet revisions.)

Application Scenarios & Design Considerations

131,072-word X 8-bit High Speed CMOS Static RAM

Alternative Part Number

  • IS61C1024AL-8TL --: 128K x 8 asynchronous SRAM with comparable 8 ns access time and 5V operation, pin-compatible in most designs and widely available.
  • CY7C128A-8PC --: 128K x 8 high-speed CMOS SRAM with 8 ns speed grade, functionally equivalent and a common drop-in replacement for Hitachi SRAMs.
  • AS6C1008-55PCN --: 128K x 8 low-power CMOS SRAM in the same DIP package family; slower 55 ns access but suitable where timing margin allows and offers long-term availability.
