Description and Introduction

CMOS STATIC RAM 256K (32K x 8-BIT) The IDT71256L20TDB is a high-speed 32K x 8-bit CMOS Static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are the key specifications, descriptions, and features:

### **Specifications:**  
- **Density:** 32K x 8-bit (256Kb)  
- **Speed:** 20ns access time  
- **Voltage Supply:** 5V ±10%  
- **Operating Current:** 70mA (typical)  
- **Standby Current:** 10mA (typical) in CMOS mode  
- **Package:** 28-pin TSOP (Thin Small Outline Package)  
- **Temperature Range:** Commercial (0°C to +70°C)  
- **I/O Type:** TTL-compatible  

### **Descriptions:**  
- The IDT71256L20TDB is a low-power, high-performance SRAM designed for applications requiring fast access times.  
- It features a fully static memory cell design, eliminating the need for external refresh.  
- The device is compatible with industry-standard 32K x 8 SRAMs.  

### **Features:**  
- **High-Speed Performance:** 20ns access time.  
- **Low Power Consumption:** CMOS technology for reduced standby current.  
- **Easy Integration:** Directly compatible with TTL levels.  
- **Reliable Operation:** Fully static design with no refresh requirement.  
- **Industry-Standard Pinout:** Drop-in replacement for similar SRAMs.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • CY7C199-20PC --: 32K x 8 asynchronous SRAM with 20 ns access time, pin-compatible with the IDT71256 series and widely available as a drop-in replacement.
  • AS7C256-20PC --: 32K x 8 low-power CMOS SRAM with 20 ns speed grade, functionally equivalent to the IDT71256L and often used as a direct second-source substitute.
  • IS61C256AL-20T --: 32K x 8 high-speed CMOS SRAM with 20 ns access time, matching the density, organization and speed of the original IDT71256L20TDB.
