Description and Introduction

32K X 8 LOW VOLTAGE CMOS STATIC RAM The IS61LV256-15TI is a high-speed 262,144-word by 16-bit (4M-bit) Static RAM (SRAM) manufactured by ISSI (Integrated Silicon Solution, Inc.).  

### **Key Specifications:**  
- **Density:** 4M-bit (256K x 16)  
- **Organization:** 262,144 words × 16 bits  
- **Access Time:** 15 ns  
- **Operating Voltage:** 3.3V  
- **Operating Current:** 85 mA (typical)  
- **Standby Current:** 5 mA (typical)  
- **Package:** 44-pin TSOP II (Thin Small Outline Package)  
- **Operating Temperature Range:** -40°C to +85°C  
- **I/O Interface:** CMOS-compatible  

### **Features:**  
- High-speed access time (15 ns)  
- Low power consumption  
- Fully static operation (no refresh required)  
- TTL-compatible inputs and outputs  
- Single 3.3V power supply  
- Three-state outputs  
- Byte control (UB#, LB#) for upper and lower byte access

This SRAM is commonly used in applications requiring high-speed, low-power memory, such as networking, telecommunications, and embedded systems.

Application Scenarios & Design Considerations

32K X 8 LOW VOLTAGE CMOS STATIC RAM

Alternative Part Number

  • CY7C199-15PC --: 32K x 8 asynchronous SRAM with 15 ns access time, functionally equivalent to the IS61LV256 and widely available as a drop-in replacement.
  • AS7C256-15PC --: 32K x 8 low-voltage SRAM with 15 ns speed grade, pin-compatible with the IS61LV256 and offered as a direct second-source option.
  • HM62256BLP-15 --: 32K x 8 SRAM with 15 ns access time in a similar DIP package, a well-established alternative when the ISSI part is unavailable.
