Description and Introduction

32K x 8 Low Power SRAM with 3.3V The IC62LV256-45U is a 256K (32K x 8) Low-Voltage CMOS Static RAM manufactured by **Cypress Semiconductor (CSI)**. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Density:** 256K (32K x 8)  
- **Technology:** Low-Voltage CMOS  
- **Speed:** 45 ns access time  
- **Voltage Supply:** 3.3V (±10%)  
- **Operating Current:** 30 mA (typical)  
- **Standby Current:** 5 µA (typical)  
- **Package:** 28-pin SOIC (Small Outline Integrated Circuit)  
- **Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  

### **Descriptions:**
- The IC62LV256-45U is a high-performance, low-power SRAM designed for applications requiring fast access times and low power consumption.  
- It is compatible with 3.3V systems and features a fully static operation, meaning no refresh cycles are required.  
- The device is suitable for battery-backed or portable applications due to its low standby current.  

### **Features:**
- **3.3V Power Supply** – Operates with a single 3.3V supply.  
- **Low Power Consumption** – Ideal for power-sensitive applications.  
- **High-Speed Access Time** – 45 ns maximum access time.  
- **Fully Static Operation** – No clock or refresh needed.  
- **TTL-Compatible Inputs/Outputs** – Ensures compatibility with standard logic levels.  
- **Industrial Temperature Support** – Available in extended temperature ranges.  
- **Automotive-Grade Options** – Some variants may support automotive applications.  

This information is based on the manufacturer's datasheet and product documentation. For detailed electrical characteristics and timing diagrams, refer to the official Cypress Semiconductor datasheet.

Application Scenarios & Design Considerations

32K x 8 Low Power SRAM with 3.3V

Alternative Part Number

  • IS62LV256-45U --: Same 32Kx8 low-voltage SRAM with 45ns access time from ISSI, the successor brand to ICSI, pin and function compatible.
  • CY62256LL-45ZXI --: 32Kx8 low-power SRAM with 45ns speed in a similar TSOP package, widely used as a drop-in replacement for 62256-type devices.
  • AS6C62256-55SIN --: 32Kx8 low-power CMOS SRAM in the same family footprint; 55ns is slightly slower but functionally compatible for most designs.
  • CY62256LL-70SNX --: 32Kx8 low-power SRAM in the same family class; slightly slower 70 ns but functionally compatible with standard pinout.
