Infineon Technologies CY62147EV30LL-45BVXIT

Overview

CY62147EV30LL-45BVXIT from Infineon Technologies (formerly Cypress) is a 4-Mbit (256K × 16) MoBL® CMOS static RAM with 45 ns access time, 2.2–3.6 V supply range, and industrial temperature rating (–40 °C to +85 °C). It delivers ultra-low standby current (2.5 µA typical), active current of 3.5 mA at 1 MHz, and supports byte-level power-down for portable battery-powered systems including cellular handsets and IoT edge nodes.

For engineers reviewing the CY62147EV30LL-45BVXIT datasheet, CY62147EV30LL-45BVXIT pinout, CY62147EV30LL-45BVXIT application, or CY62147EV30LL-45BVXIT equivalent, key selection criteria include its dual CE/BHE/BLE control architecture, VFBGA-48 package compatibility, data retention down to 1.5 V, and automatic power-down behavior triggered by CE or simultaneous BHE/BLE deassertion.

Technical Context

This SRAM implements a synchronous, non-volatile-retentive memory array organized as 256K words × 16 bits, using CMOS process technology optimized for low-power, high-speed random access. Its logic supports independent byte write enable via BHE and BLE, enabling 8-bit sub-word writes without disturbing adjacent bytes.

The device features two distinct power states: active mode (CE LOW, WE/OE controlled) and automatic standby mode (CE HIGH or both BHE/BLE HIGH), reducing ICC to ≤7 µA. Data retention remains valid down to VCC = 1.5 V with ICCDR ≤8.8 µA, supporting brown-out resilience in battery-backed systems.

FAQ

Does CY62147EV30LL-45BVXIT support true dual CE operation?

No - the 'VXIT' suffix denotes the single CE variant in VFBGA-48 package. Dual CE (CE1/CE2) is offered under different ordering codes (e.g., CY62147EV30LL-45BVXI). In single CE devices, CE functions as a unified chip select; no internal logic combines multiple CE inputs.

Can I use CY62147EV30LL-45BVXIT with a 1.8 V microcontroller I/O interface?

No - the device requires V_CC ≥2.2 V and specifies VIH(min) = 1.8 V only when V_CC = 2.2–2.7 V. Direct connection to 1.8 V logic violates input voltage thresholds; level-shifting circuitry is mandatory for interoperability.

What happens to data integrity when V_CC drops below 2.2 V but remains above 1.5 V?

Data is retained as long as V_CC ≥1.5 V and CE (or both BHE/BLE) remains asserted to maintain standby mode. However, active read/write operations are not guaranteed below V_CC(min) = 2.2 V; timing parameters and DC specs are only characterized in the full industrial range.

Is the 48-ball VFBGA package RoHS and REACH compliant?

Yes - CY62147EV30LL-45BVXIT is manufactured as a Pb-free, halogen-free device compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with full material declarations available through Infineon's product change notifications.
