The 55 ns access time and 55 ns write-cycle time define the bus timing budget for the host controller. ## 55 ns access time — bus timing and cycle budget The 55 ns access time sets the read-cycle window for the memory controller. In a system with a 20 MHz bus clock (50 ns period), this part leaves minimal margin for address-to-data setup; a faster 10 ns SRAM would be needed for zero-wait-state operation above ~18 MHz. For designs currently using a 55 ns asynchronous SRAM, this part is a direct drop-in replacement. ## Temperature range and supply — fit for harsh environments The 2.2V to 3.6V supply range covers both 3.3V and 2.5V rails without an external regulator, simplifying BOM integration. The part is RoHS3 compliant, which matters for EU and global regulatory acceptance. ## Package and footprint — 44-TSOP II Housed in a 44-TSOP II (0.400\" body width, 10.16 mm), surface-mount package. The TSOP II footprint is a common industry standard for 16-bit asynchronous SRAMs in this density class.","metaTitle":"Cypress CY62137FV30LL-55ZSXE MoBL SRAM, 2Mbit, 55 ns","metaDescription":"Cypress CY62137FV30LL-55ZSXE MoBL asynchronous SRAM: 2Mbit, 55 ns access, 2.2V-3.6V, -40°C to 125°C, 44-TSOP II.
