MoBL® 4 Mbit asynchronous SRAM — 45 ns, 2.2 V to 3.6 V, 44-TSOP II
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
The 45 ns access time sets the window from address valid to data valid on a read cycle. The write cycle time is also 45 ns.
Industrial temperature grade — -40°C to 85°C
Rated for -40°C to 85°C ambient, this SRAM is suited for factory automation, outdoor telecom cabinets, and automotive cabin applications.
Active lifecycle — no LTB pressure
The CY62146EV30LL-45ZSXIT carries an Active product status, meaning Infineon continues to manufacture it with no announced last-time-buy or end-of-life date. It is ROHS3 compliant.
