Description and Introduction

128K x 8 HIGH-SPEED CMOS STATIC RAM The IS61C1024-25T is a 1M x 8-bit high-speed CMOS static RAM (SRAM) manufactured by ISSI (Integrated Silicon Solution, Inc.).  

### **Key Specifications:**  
- **Organization:** 1,048,576 words × 8 bits  
- **Access Time:** 25 ns  
- **Operating Voltage:** 5V ±10%  
- **Low Power Consumption:**  
  - Active Current: 85 mA (typical)  
  - Standby Current: 10 mA (typical)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 32-pin TSOP (Thin Small Outline Package)  

### **Features:**  
- **High-Speed Performance:** 25 ns access time  
- **Fully Static Operation:** No clock or refresh required  
- **Tri-State Outputs:** Directly TTL-compatible  
- **CMOS Technology:** Low power consumption  
- **Single 5V Power Supply:** Simplifies system design  
- **Industrial Standard Pinout:** Compatible with other 1Mx8 SRAMs  

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

Application Scenarios & Design Considerations

128K x 8 HIGH-SPEED CMOS STATIC RAM

Alternative Part Number

  • CY7C1021-25ZC --: Pin-compatible 64K x 16 asynchronous SRAM with 25 ns access time, widely used as a drop-in replacement for the IS61C1024 in similar sockets.
  • AS7C1024-25TC --: Direct functional equivalent 64K x 16 SRAM with 25 ns speed grade and TSOP package, commonly cross-referenced for ISSI SRAM parts.
  • IS62C1024-25T --: Same manufacturer and identical 64K x 16 SRAM architecture with 25 ns access time, differing only in the low-power series prefix, making it a reliable substitute.
