Description and Introduction

32K x 8 LOW POWER CMOS STATIC RAM The IS62C256-45T is a 32K x 8-bit high-speed CMOS static RAM (SRAM) manufactured by ISSI (Integrated Silicon Solution, Inc.). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Organization:** 32K x 8 (256 Kbit)  
- **Supply Voltage:** 4.5V to 5.5V  
- **Access Time:** 45 ns  
- **Operating Current:** 40 mA (typical)  
- **Standby Current:** 10 µA (typical)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package Type:** 28-pin TSOP (Thin Small Outline Package)  
- **Pin Configuration:** Compatible with industry-standard 32K x 8 SRAMs  

### **Descriptions:**  
- **High-Speed Performance:** The 45 ns access time makes it suitable for high-performance applications.  
- **Low Power Consumption:** Features low standby current, making it ideal for battery-powered devices.  
- **CMOS Technology:** Ensures high noise immunity and low power dissipation.  
- **Fully Static Operation:** No clock or refresh required.  
- **Tri-State Outputs:** Allows direct memory expansion.  

### **Features:**  
- **Wide Voltage Range:** Supports 4.5V to 5.5V operation.  
- **Easy Interfacing:** Compatible with most microprocessors.  
- **Data Retention:** Guaranteed in standby mode with reduced voltage (2V).  
- **Industrial Standard Pinout:** Drop-in replacement for similar SRAMs.  
- **Lead-Free & RoHS Compliant:** Meets environmental standards.  

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

Application Scenarios & Design Considerations

32K x 8 LOW POWER CMOS STATIC RAM

Alternative Part Number

  • CY62256-45PC --: 32K x 8 low-power CMOS SRAM with 45 ns access time, pin-compatible with the IS62C256 in a 28-pin DIP package.
  • AS6C256-45PCN --: Direct 32K x 8 asynchronous SRAM replacement with 45 ns speed and identical pinout, commonly used as a drop-in substitute for IS62C256.
  • HM62256BLP-45 --: 32K x 8 CMOS SRAM with 45 ns access time and compatible 28-pin DIP pinout, suitable as a functional alternative.
  • CY62256LL-70SNXC --: 32K x 8 low-power SRAM in a 28-pin TSOP-I package, functionally equivalent to the IS62C256 with a slightly slower 70 ns access time that is acceptable in most designs.
  • AS6C62256-55SIN --: Direct 32K x 8 asynchronous SRAM replacement in the same 28-pin TSOP-I footprint, 55 ns speed grade, commonly used as a drop-in substitute for IS62C256 devices.
  • HM62256BLFP-7 --: Well-established 32K x 8 CMOS SRAM with compatible pinout and 70 ns access time, suitable when a slower but proven alternative to the 45 ns original is acceptable.
  • HM62256BLP-7 --: Industry-standard 32K x 8 CMOS SRAM with compatible pinout and timing, commonly cross-referenced for IS62C256 designs.
  • CY62256LL-70SNXCT --: 32K x 8 low-power SRAM in a 28-pin TSOP/SOIC package, functionally equivalent to the IS62C256 with similar access timing and pinout.
  • AS6C62256-55SCN --: Direct drop-in 32K x 8 asynchronous SRAM replacement for IS62C256, widely used as a second-source part with compatible pinout and 5V operation.
