The CY7C1049GE30-10ZSXI: The parallel interface uses a standard byte-wide data bus and 19 address lines, so it drops into legacy designs or new builds that need fast scratchpad or frame buffers.
Housed in a 44-TSOP II (0.400" body width, 10.16 mm), this is a surface-mount part.
For replacement of a failed SRAM in an existing board, the active status also means the original manufacturer channel is still open, so you are not forced into the spot market unless you need immediate fill.
This speed allows zero-wait-state operation with most MCUs running up to about 50 MHz.
