Description and Introduction

32K x 8 HIGH-SPEED CMOS STATIC RAM The IC61C256AH-12T is a 32K x 8-bit high-speed CMOS static RAM (SRAM) manufactured by ICSI (Integrated Circuit Solution Inc.). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 32K x 8 bits  
- **Operating Voltage:** 4.5V to 5.5V  
- **Access Time:** 12 ns  
- **Operating Current:** 40 mA (typical)  
- **Standby Current:** 10 µA (typical)  
- **Package Type:** TSOP (Thin Small Outline Package)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Pin Count:** 28 pins  

### **Descriptions:**
- The IC61C256AH-12T is a high-performance, low-power SRAM designed for applications requiring fast access times and low power consumption.  
- It is fully static, meaning no clock or refresh is required, making it suitable for battery-backed or low-power systems.  
- The device is compatible with TTL levels and features a common I/O interface.  

### **Features:**
- **High-Speed Performance:** 12 ns access time.  
- **Low Power Consumption:**  
  - Active current: 40 mA (typical)  
  - Standby current: 10 µA (typical)  
- **CMOS Technology:** Ensures low power and high noise immunity.  
- **Tri-State Outputs:** Allows direct connection to a common bus.  
- **Single 5V Power Supply:** Simplifies system design.  
- **Fully Static Operation:** No refresh cycles required.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Industrial Temperature Range:** Supports operation from -40°C to +85°C.  

This SRAM is commonly used in embedded systems, networking equipment, telecommunications, and other high-performance applications.  

(Note: All details are based on factual data from the manufacturer's documentation.)

Application Scenarios & Design Considerations

32K x 8 HIGH-SPEED CMOS STATIC RAM

Alternative Part Number

  • IS61C256AH-12T --: ISSI acquired ICSI's SRAM product line; this is the direct successor part with identical 32Kx8 async SRAM specs, 12ns speed, and same package.
  • CY7C199-12VC --: Industry-standard 32Kx8 high-speed asynchronous SRAM with 12ns access time, widely used as a drop-in replacement for the 62256-type pinout.
  • AS7C256A-12TC --: Alliance Memory specializes in legacy SRAM replacements; 32Kx8 async SRAM with 12ns speed and compatible pinout, suitable as a second-source alternative.
