2Mbit asynchronous SRAM in 44-TSOP II — fit check for the memory bus
The 10 ns access and write-cycle times give the bus a tight timing budget — the memory controller must have a setup-and-hold window that closes within that window, so verify the controller's AC timing against the datasheet's derating curves at your operating voltage and temperature.
For a production BOM, this means no forced requalification or redesign cycle in the near term — but as with any active semiconductor, monitor PCNs for package or wafer-fab changes that could affect timing or supply continuity.
Package and mounting — 44-TSOP II on the board
The TSOP II footprint is a standard SRAM layout shared across many 2Mbit and 4Mbit asynchronous parts from multiple vendors, so a board designed for a compatible TSOP II SRAM should accept this device without a layout change.
