Its 15 ns access time means the part can deliver data within 15 ns of the address being valid, which fits a 66 MHz bus with no wait states. The parallel interface is straightforward — no clocks, no refresh cycles — so it is a drop-in for legacy DSP or microcontroller designs that need fast scratchpad memory without DRAM controller overhead.
Supply and temperature: narrow rails, industrial range
The 1.7 V to 2.2 V supply range is tight — the board must hold that rail within 500 mV. Many modern systems run 1.8 V core logic, so this part sits naturally on a 1.8 V plane.
Package and rework: 54-TSOP II
The 54-TSOP II package (0.400" body width, 10.16 mm) is a surface-mount gull-wing leadform.
The part is no longer in factory production, so new builds rely on the independent distribution channel — surplus stock, last-time-buy inventory, and broker-sourced material. This page is the place to submit an RFQ: we source and quote against your BOM line, confirming availability and current pricing at quote time. Expect to qualify the part for production through independent supply, not factory-direct.
