IS62C256AL-45ULI
Overview
The IS62C256AL-45ULI is a high-speed, 256K bit static RAM organized as 32,768 words by 8 bits. It operates on a single 5V supply and features an asynchronous interface that requires no clock or refresh cycles, making it ideal for simplified memory expansion in legacy and industrial systems. The part is designed for low-power consumption with a maximum standby current of 120 uA.
Why Choose This Part
The 45ns access time ensures high-speed data retrieval for real-time applications without the complexity of DRAM controllers. Its CMOS technology allows for extremely low power standby modes, and the 28-pin SOP package provides a balance between compact footprint and ease of PCB routing.
Applications
Getting Started
To interface this SRAM, connect the 15-bit address bus, 8-bit data bus, and control lines (CE, OE, WE) to your processor's external memory interface (EMIF). Ensure the VDD supply is stable between 4.5V and 5.5V, and pull up the Chip Enable line to prevent accidental writes during power-up sequencing.
