Description and Introduction

128K x 8 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC RAM The IS62WV1288BLL-55HI is a high-speed CMOS static RAM (SRAM) manufactured by ISSI (Integrated Silicon Solution, Inc.). Below are the key specifications, descriptions, and features of this device:

### **Specifications:**  
- **Organization:** 128K x 8 bits  
- **Voltage Supply:** 3.3V (±10%)  
- **Access Time:** 55 ns  
- **Operating Current:** 15 mA (typical)  
- **Standby Current:** 5 µA (typical, CMOS standby)  
- **Package:** 32-pin TSOP-I (Type 1)  
- **Operating Temperature Range:** -40°C to +85°C (Industrial)  
- **Pin Count:** 32  

### **Descriptions:**  
- The IS62WV1288BLL-55HI is a low-power SRAM designed for high-performance applications.  
- It features a fully static operation, meaning no clock or refresh is required.  
- The device is compatible with industrial temperature ranges, making it suitable for harsh environments.  
- It uses a common I/O structure, simplifying interfacing with microcontrollers and processors.  

### **Features:**  
- **High-Speed Performance:** 55 ns access time.  
- **Low Power Consumption:**  
  - Active current: 15 mA (typical)  
  - Standby current: 5 µA (CMOS standby mode)  
- **Wide Voltage Range:** Operates at 3.3V (±10%).  
- **Fully Static Operation:** No refresh cycles required.  
- **Tri-State Outputs:** Allows direct interfacing with common data buses.  
- **Industrial Temperature Range:** -40°C to +85°C.  
- **TSOP-I Package:** Compact 32-pin package for space-constrained applications.  

This SRAM is commonly used in embedded systems, networking equipment, and industrial applications requiring reliable, low-power memory.

Application Scenarios & Design Considerations

128K x 8 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC RAM

Alternative Part Number

  • CY62128EV30LL-55ZXI --: 128K x 8 low-power SRAM with 55 ns access time in TSOP package, functionally equivalent to the IS62WV1288BLL-55HI and widely available.
  • AS6C1008-55TIN --: 1M-bit (128K x 8) low-power CMOS SRAM with 55 ns speed, pin-compatible replacement commonly used to substitute ISSI 62WV series parts.
  • LY62L1288-55LLI --: 128K x 8 low-power SRAM with 55 ns access time, drop-in compatible alternative for the IS62WV1288BLL series.
  • AS6C1008-55PIN --: Alliance Memory is a well-known second-source for ISSI SRAMs; this 128Kx8 low-power SRAM matches the 55 ns speed grade and TSOP/industrial temperature option, making it a drop-in functional replacement.
  • IS64WV1288EDBLL-55HI --: Newer ISSI 128Kx8 low-power SRAM generation with the same 55 ns speed and industrial temperature grade; pin-compatible upgrade path within the same vendor family.
  • LY62L1288LL-55LLI --: 128K x 8 low-power SRAM with 55 ns access time, pin-compatible alternative to the ISSI IS62WV1288BLL device.
