Description and Introduction

256K x 16 HIGH SPEED ASYNCHRONOUS CMOS STATIC RAM WITH 3.3V SUPPLY The IS61LV25616-12K is a high-speed 256K x 16 (4M-bit) Static RAM (SRAM) manufactured by ISSI (Integrated Silicon Solution, Inc.). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Density:** 4M-bit (256K x 16)  
- **Voltage Supply:** 3.3V (±10%)  
- **Access Time:** 12 ns  
- **Operating Current:** 80 mA (typical)  
- **Standby Current:** 10 µA (typical)  
- **Package:** 44-pin TSOP II (Type II)  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Organization:** 262,144 words × 16 bits  
- **I/O Type:** Common I/O (separate input/output control)  
- **Cycle Time:** 12 ns  

### **Descriptions:**
- The IS61LV25616-12K is a low-voltage CMOS SRAM designed for high-performance applications.  
- It features a fully static operation, meaning no refresh is required.  
- The device is compatible with 3.3V systems and offers fast access times for improved system performance.  
- It is commonly used in networking, telecommunications, and embedded systems.  

### **Features:**
- **High-Speed Performance:** 12 ns access time.  
- **Low Power Consumption:**  
  - Active current: 80 mA (typical)  
  - Standby current: 10 µA (typical)  
- **3.3V Single Power Supply:** Compatible with low-voltage systems.  
- **Tri-State Outputs:** Supports bus-oriented applications.  
- **CMOS Technology:** Ensures low power dissipation.  
- **Automatic Power-Down:** When deselected (CE# high).  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing.  
- **Industrial Temperature Support:** Available in -40°C to +85°C range.  
- **Lead-Free & RoHS Compliant:** Environmentally friendly.  

This SRAM is suitable for applications requiring fast, low-power memory with a compact footprint.

Application Scenarios & Design Considerations

256K x 16 HIGH SPEED ASYNCHRONOUS CMOS STATIC RAM WITH 3.3V SUPPLY

Alternative Part Number

  • CY7C1041CV33-12ZSXET --: Pin-compatible 256Kx16 asynchronous SRAM with 12 ns access time and 3.3V supply, widely used as a drop-in replacement for the IS61LV25616 series.
  • AS7C34096A-12TCN --: Alliance Memory specializes in legacy SRAM replacements; this 256Kx16 12 ns device matches the IS61LV25616 architecture and timing closely.
  • IS62WV25616EBLL-45TLI --: Same manufacturer low-power 256Kx16 SRAM in the IS62WV series with compatible pinout; slower 45 ns speed but suitable where timing margin allows.
  • CY7C1041CV33-12ZXC --: Pin-compatible 256K x 16 asynchronous SRAM with 12 ns access time, widely available and a common drop-in replacement for IS61LV25616.
  • AS7C34098A-12TCN --: 256K x 16 low-voltage SRAM with 12 ns speed in a TSOP package, functionally equivalent and often used as a second-source alternative.
  • IS62WV25616EBLL-12TLI --: Same 256K x 16 organization and 12 ns timing from a different product family, suitable when a low-power equivalent is acceptable.
