Infineon Technologies CY62147G30-45B2XIT

Overview

CY62147G30-45B2XIT from Infineon Technologies (formerly Cypress) is a 4-Mbit MoBL® SRAM with embedded single-bit error-correcting code (ECC), organized as 256K × 16, operating at 45 ns access time across 2.2 V–3.6 V supply range. It features TTL-compatible I/Os, ERR pin for real-time ECC event indication, and ultra-low standby current (8.7 µA max). Used in industrial control modules requiring data integrity under voltage fluctuation and extended temperature cycling.

For engineers reviewing the CY62147G30-45B2XIT datasheet, CY62147G30-45B2XIT pinout, CY62147G30-45B2XIT application, or CY62147G30-45B2XIT equivalent, this page delivers verified package mapping (48-ball VFBGA), ECC functional behavior, byte-select power-down logic, dual CE interface timing, and validated alternatives for memory subsystem hardening.

Technical Context

This SRAM implements a synchronous, CMOS-based memory array with integrated ECC encoder/decoder logic that detects and corrects single-bit errors on every read cycle without automatic write-back. The ERR output asserts HIGH only during correction events, enabling external fault logging.

It supports dual chip enable (CE1/CE2) addressing with CE1 LOW and CE2 HIGH for activation, and uses BHE/ BLE to gate upper/lower byte writes independently. Byte Power Down mode activates when both BHE and BLE are deasserted, forcing immediate transition to standby regardless of CE state.

FAQ

Does CY62147G30-45B2XIT support automatic error correction write-back?

No. The device detects and corrects single-bit errors during read operations and asserts the ERR pin, but does not perform automatic write-back to memory. Correction is transient and applies only to the read data path. System firmware must handle persistent correction if required, per datasheet Note 1.

What is the function of the ERR pin, and how is it electrically driven?

The ERR pin is an open-drain output that goes HIGH during a read cycle when a single-bit error is detected and corrected. It requires an external pull-up resistor (typically 4.7 kΩ to VCC) to establish a valid logic HIGH level. The pin remains LOW otherwise, including during normal reads and writes.

Can CY62147G30-45B2XIT operate at 1.8 V?

No. This variant (CY62147G30-45B2XIT) is rated for 2.2 V to 3.6 V only. The 1.65 V–2.2 V range applies only to CY62147G(E)18 variants. Operating below 2.2 V risks timing violations and ECC reliability loss, as confirmed by AC switching characteristics tables in Rev. *K datasheet.

Is the 48-ball VFBGA package lead-free and RoHS-compliant?

Yes. The CY62147G30-45B2XIT uses a Pb-free 48-ball VFBGA package compliant with EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3), as documented in the Package Diagrams section (page 19) of datasheet 001-92847 Rev. *K.
