Description and Introduction

CMOS STATIC RAM 256K (32K x 8-BIT) The **IDT71256L25P** is a high-speed CMOS Static RAM (SRAM) manufactured by Integrated Device Technology (IDT).  

### **Key Specifications:**  
- **Memory Size:** 256Kb (32K x 8-bit)  
- **Speed:** 25ns access time  
- **Voltage Supply:** 5V (±10%)  
- **Operating Temperature:** Commercial (0°C to +70°C)  
- **Package:** 28-pin Plastic DIP (Dual In-line Package)  
- **Technology:** High-speed CMOS  
- **Standby Current:** Low power consumption in standby mode  

### **Features:**  
- **Fast Access Time:** 25ns for high-performance applications  
- **Fully Static Operation:** No clock or refresh required  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing  
- **Single 5V Power Supply:** Simplifies system design  
- **Three-State Outputs:** Allows bus sharing

This SRAM is commonly used in embedded systems, networking equipment, and other applications requiring fast, reliable memory.

Application Scenarios & Design Considerations

CMOS STATIC RAM 256K (32K x 8-BIT)

Alternative Part Number

  • CY7C199-25PC --: 32K x 8 asynchronous SRAM with 25 ns access time in a 28-pin DIP, functionally equivalent to the IDT71256L25P and widely available.
  • AS7C256-25PC --: 32K x 8 low-power CMOS SRAM, 25 ns speed grade, same pinout and package, often used as a drop-in replacement for IDT71256 series parts.
  • IS61C256AL-25N --: 32K x 8 high-speed CMOS SRAM with 25 ns access time, compatible organization and interface, suitable alternative when the IDT part is unavailable.
