Overview

The IS62WV25616EBLL-45TLI is a 4Mbit asynchronous high-speed CMOS static RAM organized as 256K words by 16 bits. It operates on a wide voltage range of 2.2V to 3.6V and features a fast access time of 45 ns, making it suitable for buffering and low-latency data storage. The device is designed for low-power operation with a standby current of only 10 microamps, extending battery life in portable systems.

Why Choose This Part

This SRAM offers a simple asynchronous interface that requires no clock or refresh cycles, simplifying timing requirements for the host controller. Its extremely low standby current of 10 microamps and lead-free 44-pin TSOP Type II package make it an efficient choice for compact, power-sensitive industrial designs.

Applications

Microcontroller Memory Expansion
Provides external volatile storage for MCUs that lack sufficient internal RAM for large data arrays or communication buffers.
Industrial Data Logging
Used as a high-speed scratchpad for temporary storage of sensor data before processing or non-volatile logging.
Communication Hubs
Functions as a network packet buffer in industrial gateways and routers requiring deterministic timing.
Embedded Display Buffering
Stores frame data for small graphical displays where high-speed parallel access is required for flicker-free updates.

Getting Started

To use this device, interface the 18 address lines and 16 data lines to your MCU or FPGA parallel bus, ensuring the chip select (CS) and output enable (OE) pins are managed for timing compliance. Hardware designers should place 0.1 microfarad decoupling capacitors close to the VDD pins to mitigate switching noise during the 45 ns access cycles. No specialized software drivers are required beyond standard memory-mapped I/O configuration.
