Description and Introduction

64K x 8 HIGH-SPEED CMOS STATIC RAM The IS61C512-25J is a 512K (64K x 8) high-speed CMOS static RAM (SRAM) manufactured by ISSI (Integrated Silicon Solution, Inc.).  

### **Key Specifications:**  
- **Organization:** 64K x 8  
- **Operating Voltage:** 5V ±10%  
- **Access Time:** 25ns  
- **Operating Current:** 70mA (typical)  
- **Standby Current:** 10μA (typical)  
- **Package:** 28-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  

### **Features:**  
- **High-Speed Performance:** 25ns access time  
- **Low Power Consumption:** CMOS technology for reduced power usage  
- **Fully Static Operation:** No clock or refresh required  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels  
- **Tri-State Outputs:** Allows bus sharing in multi-master systems  
- **Industrial Standard Pinout:** Compatible with other 64K x 8 SRAMs  

This SRAM is commonly used in applications requiring fast, low-power memory, such as embedded systems, networking devices, and industrial controls.

Application Scenarios & Design Considerations

64K x 8 HIGH-SPEED CMOS STATIC RAM

Alternative Part Number

  • CY7C199-25VC --: 32K x 8 asynchronous SRAM with 25 ns access time, functionally equivalent to the IS61C512 and pin-compatible in most designs.
  • AS7C256-25JC --: 32K x 8 high-speed CMOS SRAM with 25 ns speed grade, direct functional replacement for the IS61C512-25J.
  • HM62256BLP-25 --: 32K x 8 low-power SRAM with 25 ns access time, widely used as a drop-in substitute for ISSI 512Kb SRAM parts.
