CY62146EV30LL-45BVXI

Product Overview

The CY62146EV30LL-45BVXI from Cypress Semiconductor Corp is an asynchronous SRAM IC with a volatile 4Mbit memory array organized as 256K x 16. It uses a parallel memory interface and a 48-VFBGA (6x8) surface-mount package. The device operates from a 2.2 V to 3.6 V supply and has an operating temperature range of -40°C to 85°C (TA), supporting board-level integration in embedded designs that require a fixed-capacity random-access memory buffer.

Design & Procurement Notes

Designers selecting the CY62146EV30LL-45BVXI should align the host controller with the 256K x 16 parallel SRAM interface and verify that the system supply voltage remains within 2.2 V to 3.6 V. The 45 ns access time and 45 ns write cycle time for word and page operations should be compared with the controller read/write timing requirements. Because the memory type is volatile, the device depends on the supply voltage for data retention. The 48-VFBGA (6x8) surface-mount package should be reflected in the PCB footprint, and the -40°C to 85°C (TA) operating temperature range should be considered during thermal planning. The exact part number should be retained in the bill of materials to preserve the specified package, voltage range, memory size, organization, interface, and timing values.
