1 Mbit asynchronous SRAM in 32-SOIC
The CY62128ELL-45SXIT is a 1 Mbit asynchronous SRAM from Infineon's MoBL® series, organized as 128K x 8 bits with a parallel interface. The 45 ns access time sets the read-cycle floor — the processor must insert wait states for any bus cycle shorter than that, so this part fits best with 8-bit MCUs or FPGAs running below 22 MHz bus speed.
Package and rework considerations
Housed in a 32-SOIC (0.445-inch body width, 11.30 mm), this is a gull-wing surface-mount package with 1.27 mm pitch — easy to hand-solder or rework with hot air. The wide lead pitch means you can probe every pin on a prototype board without a microscope. Supplied in Tape & Reel (TR) or Cut Tape (CT) — the TR option is standard for pick-and-place assembly; CT suits prototype or low-volume builds. The package body is moisture-sensitive, so a bake cycle before reflow is needed if the bag seal is broken and the floor life has been exceeded.
Active lifecycle and compliance
It is ROHS3 compliant (lead-free), so it passes the material declaration for EU and most global markets without an exemption claim.
