4 Mbit SRAM in a 48-ball VFBGA — what the 70 ns access means for your bus
The Cypress CY62147CV30LL-70BVIT is a 4 Mbit (256K x 16) parallel SRAM from the MoBL® series, packaged in a 48-ball VFBGA. It runs on a 2.7 V supply and delivers a 70 ns access time.
70 ns vs 10 ns — where the speed difference lands
The CY62147CV30LL-70BVIT is a 70 ns part. The closest same-density peer in the Cypress family, the CY7C1041GE30-10ZSXI, also 4 Mbit and 256K x 16, clocks a 10 ns access time.
Active lifecycle — no end-of-life surprise
The CY62147CV30LL-70BVIT carries an Active lifecycle status. That means Cypress (now Infineon) is still manufacturing it, no last-time-buy notice has been issued, and you can qualify it into a new production BOM without worrying about a forced redesign mid-run. The part is RoHS compliant, so it passes the EU directive for lead-free assembly — no exemption paperwork needed.
