Description and Introduction

32K x 8 LOW VOLTAGE STATIC RAM The IS62LV256-45U is a 256K (32K x 8) low-voltage CMOS static RAM (SRAM) manufactured by ISSI (Integrated Silicon Solution, Inc.). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Organization:** 32K x 8  
- **Operating Voltage:** 3.3V (±10%)  
- **Access Time:** 45 ns  
- **Operating Current:** 15 mA (typical)  
- **Standby Current:** 10 µA (typical)  
- **Temperature Range:**  
  - Commercial (0°C to +70°C)  
  - Industrial (-40°C to +85°C)  
- **Package:** 28-pin SOJ, TSOP, or PDIP  

### **Descriptions:**  
- The IS62LV256-45U is a high-performance, low-power SRAM designed for battery-operated and portable applications.  
- It is fully static, meaning no refresh cycles are required.  
- The device is compatible with most microcontrollers and processors.  
- It features a TTL-compatible interface and operates with a single 3.3V power supply.  

### **Features:**  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **High-Speed Access:** 45 ns access time for fast read/write operations.  
- **Wide Operating Voltage:** Supports 3.3V ±10% tolerance.  
- **Data Retention:** Guaranteed data retention in standby mode.  
- **Three-State Outputs:** Allows direct interfacing with common bus structures.  
- **CMOS Technology:** Ensures low power dissipation.  
- **Industrial-Grade Option:** Available for extended temperature range applications.  

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

Application Scenarios & Design Considerations

32K x 8 LOW VOLTAGE STATIC RAM

Alternative Part Number

  • CY62256LL-70SNXC --: 32K x 8 low-power SRAM with similar 5V-tolerant interface and pinout; widely available and a common drop-in for ISSI 32Kx8 SRAMs, though access time is 70ns instead of 45ns.
  • AS6C62256-55SIN --: 32K x 8 low-power CMOS SRAM in the same industry-standard pinout, direct functional replacement for IS62LV256 series; 55ns speed is adequate for most designs.
  • LY62256SL-55LL --: 32K x 8 low-power SRAM with compatible pinout and 5V operation, offered as a cost-effective second-source alternative to ISSI low-power SRAMs.
