Description and Introduction

4 M PSRAM (512-kword x 8-bit) 2 k Refresh The part **HM658512ALP-8V** is a **512K x 8-bit high-speed CMOS static RAM (SRAM)** manufactured by **HIT (Hitachi)**.  

### Key Specifications:  
- **Organization**: 512K × 8-bit  
- **Technology**: High-speed CMOS  
- **Operating Voltage**: **5V ±10%**  
- **Access Time**: **8 ns** (as indicated by the "-8V" suffix)  
- **Package**: **32-pin PLCC (Plastic Leaded Chip Carrier)**  
- **Operating Temperature Range**: Commercial (0°C to +70°C) or Industrial (-40°C to +85°C) depending on variant  
- **Standby Current**: Low power consumption in standby mode  
- **I/O Compatibility**: TTL-compatible inputs and outputs  

This SRAM is commonly used in high-performance computing, networking, and embedded systems requiring fast access times.  

(Note: Verify exact temperature range and standby current from datasheet if precise details are needed.)

Application Scenarios & Design Considerations

4 M PSRAM (512-kword x 8-bit) 2 k Refresh

Alternative Part Number

  • IS61C512-15T --: 512K x 8 asynchronous SRAM with similar 8-bit organization and access time, widely available and pin-compatible in many designs.
  • CY7C185-15PC --: 64K x 8 high-speed SRAM from a different series, suitable replacement when density and timing requirements are compatible.
  • AS6C5128-55TIN --: 512K x 8 low-power CMOS SRAM offering comparable density and interface, often used as a drop-in alternative for legacy SRAM parts.
