Download the IS61LF51218A datasheet PDF.
This datasheet also covers the IS61LF25636A variant, as both devices belong to the same 256k x 36-512k x 18 9mb synchronous flow-through static ram family and are provided as variant models within a single manufacturer datasheet.
General Description
high-speed, low-power synchronous static RAMs designed to provide burstable, high-performance memory for communication and networking applications.
The IS61LF/ VF25636A is organized as 262,144 words by 36 bits.
Key Features
Internal self-timed write cycle.
Individual Byte Write Control and Global Write.
Clock controlled, registered address, data and control.
Burst sequence control using MODE input.
Three chip enable option for simple depth expansion and address pipelining.
Note: The manufacturer provides a single datasheet file (IS61LF25636A_IntegratedSiliconSolution.pdf) that lists specifications for multiple related part numbers.
