Description and Introduction

256K x 16 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC SRAM The IS62WV25616BLL-70T is a high-performance CMOS static RAM (SRAM) manufactured by ISSI (Integrated Silicon Solution, Inc.). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Organization:** 256K words × 16 bits (4Mbit)  
- **Voltage Supply:** 3.3V (±10%)  
- **Access Time:** 70ns  
- **Operating Current:** 25mA (typical)  
- **Standby Current:** 10μA (typical)  
- **Operating Temperature Range:**  
  - Commercial: 0°C to +70°C  
  - Industrial: -40°C to +85°C  
- **Package Type:** 44-pin TSOP-II (Thin Small Outline Package)  
- **Pin Count:** 44  

### **Descriptions:**
- The IS62WV25616BLL-70T is a low-power SRAM designed for applications requiring high-speed data access and low power consumption.  
- It features a fully static operation, meaning no refresh cycles are required.  
- The device is compatible with most microcontrollers and processors operating at 3.3V.  

### **Features:**
- **High-Speed Performance:** 70ns access time.  
- **Low Power Consumption:**  
  - Active current: 25mA (typical).  
  - Standby current: 10μA (typical) with CMOS input levels.  
- **Wide Voltage Range:** Operates at 3.3V ±10%.  
- **Fully Static Operation:** No clock or refresh required.  
- **Tri-State Outputs:** Allows direct connection to a common bus.  
- **Byte Control:** Supports upper and lower byte access via UB# (Upper Byte) and LB# (Lower Byte) control pins.  
- **Industrial Temperature Support:** Available in industrial-grade (-40°C to +85°C).  
- **TSOP-II Package:** Compact form factor suitable for space-constrained applications.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

256K x 16 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC SRAM

Alternative Part Number

  • CY7C1041G-10ZSXI --: Pin-compatible 256K x 16 asynchronous SRAM with similar 70-100 ns access time and 3.3V supply, widely used as a drop-in alternative to ISSI 25616 parts.
  • AS6C4016-55TIN --: Alliance Memory specializes in legacy SRAM replacements; this 256K x 16 low-power SRAM matches the organization and 3.3V interface with comparable timing.
  • IS64WV25616EDBLL-10CTLA3 --: Newer ISSI 256K x 16 high-speed SRAM from a different series, offering the same density and pinout with improved speed grades as a forward replacement.
