IS62WV25616BLL-55TLI
Overview
The IS62WV25616BLL-55TLI is a 4Mbit asynchronous CMOS static RAM organized as 256K words by 16 bits. It operates on a low-voltage supply range of 2.5V to 3.6V and features a fast 55ns access time suitable for high-performance embedded systems. This memory is fully static, requiring no external clock or refresh cycles, which simplifies the interface design for various microcontrollers and digital signal processors.
Why Choose This Part
This SRAM offers extremely low power consumption with a standby current of only 15uA and a maximum operating current of 40mA. The dual-byte control (upper and lower bytes) allows for flexible 8-bit or 16-bit data bus interfacing. Its asynchronous architecture and TTL-compatible levels eliminate the complexity of timing controllers required by DRAM or synchronous memory types.
Applications
Key Specifications
Getting Started
To integrate this SRAM, connect the 18-bit address bus and 16-bit data bus to your processor's external memory interface (EMIF) or FSMC. Ensure the VDD supply is decoupled with 0.1uF capacitors near the power pins and manage the Chip Select (CS), Output Enable (OE), and Write Enable (WE) signals according to the 55ns timing diagrams. The 44-pin TSOP-II package is suitable for standard SMT reflow profiles and can be easily prototyped on adapter boards.
