Infineon Technologies CY62147GE-45ZSXI

Overview

CY62147GE-45ZSXI 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 2.2–3.6 V supply. It features an ERR output pin for real-time ECC event indication, ultra-low standby current (8.7 µA max), and TTL-compatible I/Os. Used in industrial control modules requiring data integrity during long-term operation.

For engineers reviewing the CY62147GE-45ZSXI datasheet, CY62147GE-45ZSXI pinout, CY62147GE-45ZSXI application, or CY62147GE-45ZSXI equivalent, key selection criteria include ECC-enabled memory reliability, dual-voltage support (2.2–3.6 V), 45 ns timing, 48-ball VFBGA package compatibility, and ERR signal behavior during read cycles.

Technical Context

This SRAM implements on-die ECC encoding/decoding logic that detects and corrects single-bit errors in accessed 16-bit words without automatic write-back. The ERR pin asserts HIGH only during read cycles when correction occurs, enabling system-level error logging.

It supports both single and dual chip enable configurations, byte-level writes via BHE/ BLE, and seamless standby entry when both byte enables are deasserted - independent of CE state. Address range spans A0–A17 (18 bits), covering 256K words.

FAQ

Does CY62147GE-45ZSXI support automatic error correction write-back?

No. The device detects and corrects single-bit errors during read operations but does not perform automatic write-back to memory. Corrected data appears on I/O lines, and the ERR pin signals the event. System firmware must decide whether to re-write the corrected word based on application requirements and error frequency monitoring.

What is the function of the ERR pin during write cycles?

The ERR pin is inactive during write cycles - it only asserts HIGH during read cycles when a single-bit error is detected and corrected in the accessed 16-bit word. It remains in high-impedance state otherwise, and its behavior is undefined during writes per datasheet specification.

Can CY62147GE-45ZSXI operate at 1.8 V?

No. The -45ZSXI speed grade is specified only for the 2.2 V to 3.6 V VCC range. While the broader CY62147GE family includes a 1.65–2.2 V variant (e.g., -55ZSXI), the -45ZSXI suffix explicitly denotes qualification and timing guarantee at 2.2–3.6 V.

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

Yes. The CY62147GE-45ZSXI uses a Pb-free 48-ball VFBGA package compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3), with peak reflow temperature of 260 °C.
