For BOM sustainment, the part must be sourced through independent distribution or from remaining channel stock.
512K x 32 wide-bus SRAM at 10 ns
This is a 16Mbit asynchronous SRAM organized as 512K words by 32 bits. The wide data bus matches a 32-bit processor or DSP directly, reducing chip count on the memory bus.
Industrial temperature and 3.3 V supply
The write cycle time matches the read access at 10 ns, so back-to-back write bursts run at the same speed as reads.
119-PBGA (14x22 mm) footprint
Packaged in a 119-ball PBGA, 14x22 mm body. The 1.0 mm ball pitch requires a multi-layer PCB for fan-out — four layers minimum, with the inner planes carrying the 3.3 V rail and ground. The BGA footprint also means the part is moisture-sensitive; bake before reflow if the bag humidity indicator card shows >10% RH.
