Infineon Technologies CY62147G30-45BVXI

Overview

CY62147G30-45BVXI from Infineon Technologies (formerly Cypress) is a 4-Mbit MoBL® SRAM with embedded single-bit error-correcting code (ECC), organized as 256K × 16-bit, operating at 45 ns access time across 2.2 V–3.6 V supply range. It features TTL-compatible I/Os, ERR output for error indication, and dual chip enable (CE1/CE2) logic. Used in industrial control modules requiring data integrity under radiation-prone or long-term reliability conditions.

For engineers reviewing the CY62147G30-45BVXI datasheet, CY62147G30-45BVXI pinout, CY62147G30-45BVXI application, or CY62147G30-45BVXI equivalent, key selection criteria include ECC-enabled memory integrity, ultra-low standby current (≤8.7 µA), 45 ns timing at 3.0 V, dual CE interface compatibility, and VFBGA-48 packaging for space-constrained embedded systems.

Technical Context

This SRAM implements a synchronous, byte-selectable architecture with dedicated BHE/ BLE controls enabling independent upper- and lower-byte writes. Its ECC engine performs real-time single-bit correction without automatic write-back, and asserts ERR high during correction events - confirmed by truth table and logic block diagram on pages 2 and 16 of Rev. *K datasheet.

The device supports three V_CC ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V); this variant is rated for 2.2–3.6 V operation at 45 ns. Standby power is minimized via Byte Power Down mode: when both BHE and BLE are deasserted, the device enters low-power state regardless of CE states.

FAQ

Does CY62147G30-45BVXI support automatic error write-back after correction?

No. As explicitly stated in Note 1 of the datasheet (Rev. *K, page 1), this device does not support automatic write-back on error detection. The corrected data remains internal to the ECC decoder and is presented on I/O lines during the read cycle, but the original corrupted bit location is not rewritten in memory.

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

The ERR pin is an open-drain output that asserts HIGH during detection and correction of a single-bit error in the accessed memory location. It requires an external pull-up resistor (typically 4.7 kΩ to V_CC) and can drive interrupt inputs of microcontrollers or status LEDs without additional buffering.

Can CY62147G30-45BVXI operate reliably at 1.8 V?

No. This specific variant (CY62147G30-45BVXI) is rated for 2.2 V–3.6 V operation only. For 1.65 V–2.2 V operation, the CY62147G18-55BVXI variant must be used - mixing voltage ranges risks timing violations and increased standby current beyond specification.

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

Yes. Per the "Pb-free" designation in the datasheet title and Package Diagrams section (page 19), the VFBGA package uses lead-free solder balls and complies with EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 requirements.
