Description and Introduction

256K x 8 LOW POWER and LOW Vcc CMOS STATIC RAM The IS62LV2568LL-85H is a 256K x 8-bit low-voltage CMOS static RAM (SRAM) manufactured by ISSI (Integrated Silicon Solution Inc.).  

### **Key Specifications:**  
- **Organization:** 256K x 8-bit  
- **Operating Voltage:** 3.3V (±10%)  
- **Access Time:** 85ns  
- **Operating Current:** 30mA (typical)  
- **Standby Current:** 10μA (typical)  
- **Package:** 28-pin SOJ, TSOP I, or PDIP  
- **Temperature Range:** Commercial (0°C to +70°C) and Industrial (-40°C to +85°C)  

### **Features:**  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Fully Static Operation:** No refresh required.  
- **Tri-State Outputs:** Supports bus-oriented systems.  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing.  
- **Data Retention Voltage:** 2V (min) for battery backup operation.  
- **High-Speed Performance:** Suitable for embedded systems and cache applications.  
- **Industrial-Grade Reliability:** Available in extended temperature ranges.  

This SRAM is commonly used in networking, telecommunications, and embedded systems requiring fast, low-power memory.

Application Scenarios & Design Considerations

256K x 8 LOW POWER and LOW Vcc CMOS STATIC RAM

Alternative Part Number

  • CY62256LL-70SNXC --: 32K x 8 low-power asynchronous SRAM with similar 5V/3.3V-compatible interface and access time class; widely available and pin-compatible in many designs.
  • AS6C62256-55SCN --: 32K x 8 low-power CMOS SRAM, direct functional equivalent to the IS62LV256 family with comparable speed grade and SOIC package options.
  • LY62L2568LL-70LL --: 32K x 8 low-voltage low-power SRAM from a second-source vendor, matching the IS62LV2568 architecture and suitable as a drop-in replacement in most applications.
