IS62WV12816BLL-55TLI
Overview
The IS62WV12816BLL-55TLI is a 2-Mbit asynchronous CMOS static RAM organized as 128K words by 16 bits. It operates on a single power supply ranging from 2.5V to 3.6V and features a 55ns access time for high-speed data retrieval. This memory is designed for low-power operation, featuring a standby current of only 10uA to preserve battery life in portable applications.
Why Choose This Part
This SRAM offers fully static operation, meaning no clock or refresh cycles are required, which simplifies the interface logic for the designer. It includes dedicated data control for both upper and lower bytes, allowing for flexible 8-bit or 16-bit access modes. The wide operating temperature range of -40 to 85 degrees Celsius ensures reliability in harsh industrial environments.
Applications
Key Specifications
Getting Started
To interface this SRAM, connect the 17-bit address bus and 16-bit data bus to your microcontroller's external memory interface (EMC or FSMC). Ensure that the Chip Enable (CE), Output Enable (OE), and Write Enable (WE) pins are properly toggled according to the 55ns timing diagrams in the datasheet. For 8-bit operations, use the LB (Lower Byte) and UB (Upper Byte) control pins to mask specific data lines.
