What this MoBL SRAM brings to the board
The Infineon CY62138FV30LL-45ZAXIT is a 2 Mbit asynchronous SRAM from the MoBL® series, organized as 256K x 8 and accessed through a parallel interface. Its 45 ns access time sets the timing floor for any bus cycle — the controller must be able to meet that window or add wait states.
The 45 ns access time and 45 ns write cycle time match, so back-to-back writes incur no extra penalty.
Package and footprint
Housed in a 32-sTSOP (0.465" body width, 11.80 mm), this is a surface-mount part.
Lifecycle and compliance
ROHS3 compliant per the listing, which means it passes the current EU restriction thresholds without an exemption.
