Product details

The Infineon CY62146EV30LL-45ZSXIT is a 4 Mbit asynchronous SRAM from the MoBL® (More Battery Life) series, organized as 256K words by 16 bits. It is a volatile, parallel-interface memory with a 45 ns access time and a 45 ns write cycle time, operating from a 2.2 V to 3.6 V supply over the industrial temperature range of -40°C to 85°C. The part is housed in a 44-TSOP II (0.400", 10.16 mm width) surface-mount package and is supplied in Tape & Reel or Cut Tape. It is designed for applications requiring low standby power and a wide voltage range — typical in portable instruments, industrial controllers, and telecom line cards where battery-backed or low-voltage SRAM is needed.

45 ns access time — bus timing margin

It is ROHS3 compliant.

Frequently asked questions

Is CY62146EV30LL-45ZSXIT RoHS compliant?

Yes, it is ROHS3 compliant.

When sourcing CY62146EV30LL-45ZSXIT, what is the closest functional second-source?

The closest functional peer in the same 4 Mbit, 2.2 V to 3.6 V, 44-TSOP II footprint is the CY7C1041GN30-10ZSXIT, which offers a 10 ns access time. The faster speed may require bus-timing adjustment in your controller.
