Description and Introduction

CMOS STATIC RAM 256K (32K x 8-BIT) The IDT71256L35Y is a high-speed 32K x 8-bit static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 32K x 8-bit (262,144 bits)  
- **Access Time:** 35 ns  
- **Operating Voltage:** 5V ±10%  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 28-pin SOJ (Small Outline J-Lead)  
- **Power Consumption:**  
  - Active: 750 mW (max)  
  - Standby: 5 mW (max)  
- **I/O Interface:** TTL-compatible  
- **Cycle Time:** 35 ns  

### **Descriptions:**
- The IDT71256L35Y is a high-performance CMOS static RAM designed for applications requiring fast access times and low power consumption.  
- It is fully static, meaning no refresh cycles are required, and it retains data as long as power is supplied.  
- Suitable for cache memory, embedded systems, and other high-speed computing applications.  

### **Features:**
- **High-Speed Operation:** 35 ns access time.  
- **Low Power Consumption:** CMOS technology ensures reduced power usage in both active and standby modes.  
- **Fully Static Design:** No clock or refresh needed.  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing with standard logic circuits.  
- **Single 5V Power Supply:** Simplifies system power requirements.  
- **Three-State Outputs:** Allows for bus-oriented applications.  
- **Industrial Standard Pinout:** Compatible with other 32K x 8 SRAMs.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • CY7C199-35PC --: 32K x 8 asynchronous SRAM with 35 ns access time, pin-compatible with the IDT71256L35Y and widely available from a different vendor.
  • AS7C256-35PC --: 32K x 8 low-power CMOS SRAM, 35 ns speed grade, functionally equivalent and often used as a drop-in replacement for IDT71256 series parts.
  • IS61C256AH-35N --: 32K x 8 high-speed SRAM with 35 ns access time, same JEDEC pinout and function, suitable alternative from a different manufacturer.
