The Cypress CY62148DV30LL-70BVXI is a 4Mbit MoBL® asynchronous SRAM organized as 512K x 8 bits. It runs on a 2.2 V supply and delivers a 70 ns access time over the industrial temperature range of -40°C to 85°C. The parallel interface and 48-ball VFBGA suit it for cache buffers, working memory, and data-logging storage in embedded controllers, telecom line cards, and industrial automation modules where low power and a small footprint matter.
70 ns access time — timing margin for the bus
2.2 V supply — low-voltage system fit
The 2.2 V supply rail places this SRAM in the low-voltage family.
Infineon (formerly Cypress) lists this part as Active. No imminent last-time-buy risk is flagged.
