  - Industrial (-40°C to +85°C)  
- **Package Type:** 28-pin SOJ (Small Outline J-Lead)  

### **Descriptions:**  
- **Type:** Asynchronous CMOS SRAM  
- **Functionality:** Non-volatile memory (retains data without power)  
- **Interface:** Parallel, compatible with standard TTL levels  

### **Features:**  
- **High-Speed Performance:** 25 ns access time  
- **Low Power Consumption:** CMOS technology for reduced power usage  
- **Wide Voltage Tolerance:** Operates at 5V ±10%  
- **Three-State Outputs:** Allows bus sharing in multi-processor systems  
- **Industrial-Grade Reliability:** Available in extended temperature ranges  
- **Pin-Compatible:** Drop-in replacement for similar SRAMs  

This SRAM is commonly used in applications requiring fast, reliable data storage, such as embedded systems, networking devices, and industrial controllers.

Application Scenarios & Design Considerations

CMOS STATIC RAM 64K (8K x 8-BIT)

Alternative Part Number

  • CY7C199-25PC --: 32K x 8 asynchronous SRAM with 25 ns access time, functionally equivalent to the IDT7164 and widely available as a drop-in replacement.
  • AS7C256-25PC --: 32K x 8 low-power CMOS SRAM with 25 ns speed grade, pin-compatible with the IDT7164 series and offered as a direct second-source option.
  • IS61C256AL-25T --: 32K x 8 high-speed CMOS SRAM with 25 ns access time, matching the density and timing of the original IDT7164S25 part.
