The Infineon CY7C1021CV26-15ZSXET is a 1Mbit asynchronous SRAM organized as 64K x 16 bits, accessed through a parallel interface.
15 ns access time — timing margin on the bus
For a 16-bit microcontroller or DSP running at 40–50 MHz, this leaves roughly 5–10 ns of setup margin after accounting for PCB trace delay and clock jitter. Verify that the controller's address-to-data setup window is at least 15 ns minus the clock-to-output skew of the address latch.
Housed in a 44-TSOP II (0.400" body width, 10.16 mm wide), this is a surface-mount package with a standard JEDEC footprint. The Tape & Reel (TR) shipping medium is typical for automated pick-and-place. No thermal pad or exposed paddle — all heat dissipates through the leads and the PCB copper.
