Infineon Technologies CY62147G30-45BVXA

Overview

CY62147G30-45BVXA from Cypress Semiconductor is an automotive-grade 4-Mbit (256K × 16-bit) MoBL® Static RAM with embedded single-bit error-correcting code (ECC), rated for –40 °C to +85 °C operation, 45 ns access time, and ultra-low standby current of 3.5 µA at 2.2–3.6 V supply. It supports byte-level write control via BHE/ BLE and features TTL-compatible I/Os for use in engine control units and ADAS domain controllers.

For engineers reviewing the CY62147G30-45BVXA datasheet, CY62147G30-45BVXA pinout, CY62147G30-45BVXA application, or CY62147G30-45BVXA equivalent, key selection criteria include ECC-enabled data integrity, automotive-A temperature compliance, VFBGA-48 packaging, dual-byte enable architecture, and automatic power-down behavior triggered by simultaneous BHE/ BLE deassertion.

Technical Context

This SRAM implements a synchronous CMOS memory array with integrated ECC encoding/decoding logic that detects and corrects single-bit errors on read operations without automatic write-back. The device uses separate row/column decoders and sense amplifiers optimized for low-power automotive environments.

It supports two chip-enable configurations: single CE (CY62147G) and dual CE1/CE2 (CY621472G); this part uses the single CE variant. Byte power-down is activated when both BHE and BLE are HIGH, forcing automatic transition to standby mode regardless of CE state - enabling dynamic power gating in safety-critical systems.

FAQ

Does CY62147G30-45BVXA support automatic error correction during read operations?

Yes - the device performs real-time single-bit error correction on every read access using on-die ECC logic. Detected errors are corrected before data reaches the I/O bus, and no external intervention or software handling is required. However, it does not perform automatic write-back upon correction, as stated in Note 1 of the datasheet.

What is the function of the Byte Power-down feature?

The Byte Power-down feature activates automatically when both BHE and BLE inputs are held HIGH, forcing the device into ultra-low-power standby mode regardless of CE state. This enables precise power gating at the byte-access level, reducing system-level quiescent current without requiring changes to chip-select sequencing.

Is CY62147G30-45BVXA pin-compatible with CY621472G variants?

No - CY62147G uses a single CE input, while CY621472G uses dual CE1/CE2 inputs. Their pinouts differ: CY62147G maps CE to ball D2 in VFBGA, whereas CY621472G replaces that pin with CE2 and adds CE1 at ball G1. Board-level substitution requires schematic and layout revision.

Can CY62147G30-45BVXA operate at 1.8 V supply?

No - the absolute minimum VCC is 2.2 V per the Operating Range table. Although some parameters are characterized at 1.8 V for other Cypress families, this part's DC and AC specifications are guaranteed only from 2.2 V to 3.6 V. Operation below 2.2 V may result in data retention loss or timing violations.
