Product details

1 Mbit asynchronous SRAM for legacy 16-bit buses

This part is a fit for legacy embedded systems that require a fast, byte-wide or word-wide scratchpad memory — think DSP data buffers, cache tag stores, or real-time control lookup tables in motor drives and telecom line cards. The 44-SOJ package is a surface-mount footprint common in late-1990s through 2000s designs.

For a 16-bit MCU or DSP running at 40–66 MHz, this gives roughly one to two clock cycles of margin after accounting for PCB trace delay and output load.

Obsolete — sourcing reality and channel

Infineon (formerly Cypress) has discontinued this density and voltage variant.

The 44-SOJ (BSOJ) package is a JEDEC surface-mount form factor with a 0.400-inch body width and 10.16 mm width. It is a legacy footprint — not common on new PCB layouts, but still supported by many assembly houses for rework. The 2.5V–2.7V supply is narrow; a 2.5 V ±2% regulator is adequate, but a 2.7 V rail requires tighter tolerance.
