2. **Voltage Supply:** 3.3V  
3. **Access Time:** 10 ns  
4. **Operating Current:** 70 mA (typical)  
5. **Standby Current:** 10 µA (typical)  
6. **Package:** 28-pin TSOP-I (Thin Small Outline Package)  
7. **Temperature Range:** Industrial (-40°C to +85°C)  
8. **Organization:** 262,144 words x 8 bits  

### **Descriptions:**
- The IS61LV2568L-10KI is a high-performance, low-power SRAM designed for applications requiring fast access times and low power consumption.  
- It is commonly used in networking, telecommunications, and embedded systems.  
- The device operates with a single 3.3V power supply and is compatible with TTL levels.  

### **Features:**
1. **High-Speed Performance:** 10 ns access time.  
2. **Low Power Consumption:**  
   - Active current: 70 mA (typical)  
   - Standby current: 10 µA (typical)  
3. **TTL-Compatible Inputs and Outputs.**  
4. **Fully Static Operation:** No refresh or clock required.  
5. **Three-State Outputs.**  
6. **Industrial Temperature Range (-40°C to +85°C).**  
7. **Available in Lead-Free (RoHS Compliant) Packaging.**  

This SRAM is suitable for applications requiring fast, reliable, and low-power memory solutions.

Application Scenarios & Design Considerations

256K x 8 HIGH-SPEED CMOS STATIC RAM

Alternative Part Number

  • CY7C1091DV33-10ZSXI --: 32K x 8 asynchronous SRAM with 10 ns access time in the same 3.3 V low-power class, pin-compatible TSOP package, widely available and a common drop-in for ISSI 256K-bit SRAMs.
  • AS7C34098A-10TCN --: Alliance Memory specializes in legacy SRAM replacements; this 256K x 8 10 ns 3.3 V device matches the IS61LV2568L speed and organization and is offered as a direct second-source alternative.
  • IS64WV2568EDBLL-10BLA3 --: Newer ISSI 256K x 8 10 ns 3.3 V SRAM from a different series, offering the same density, speed grade and interface with improved process and long-term availability.
  • CY7C1354B-100AXC --: Cypress SRAM with similar 256Kx8 asynchronous architecture and 10 ns class speed, widely available and pin-compatible in many designs.
  • AS7C256A-10TCN --: Alliance Memory 256Kx8 low-power asynchronous SRAM, direct functional equivalent to the IS61LV2568L with comparable 10 ns access time.
  • IS62WV2568EBLL-10TI --: ISSI low-power 256Kx8 SRAM from a different series, offering similar density, speed grade, and supply voltage as a drop-in functional replacement.
