Infineon Technologies CY62177G30-55BAXI

Overview

CY62177G30-55BAXI from Infineon Technologies (formerly Cypress) is a 32-Mbit MoBL® SRAM with embedded single-bit error-correcting code (ECC), configured as 2M × 16 or 4M × 8, operating at 55 ns access time over 2.2–3.6 V supply. It features ultra-low standby current (max 19 µA), TTL-compatible I/Os, and Byte Power-down mode for dynamic power savings. Used in industrial control systems requiring data integrity and low-power retention.

For engineers reviewing the CY62177G30-55BAXI datasheet, CY62177G30-55BAXI pinout, CY62177G30-55BAXI application, or CY62177G30-55BAXI equivalent, key selection criteria include ECC-enabled reliability, dual chip enable support, TSOP I package compatibility, 55 ns timing margin, and industrial-grade temperature operation (–40 °C to +85 °C).

Technical Context

This SRAM integrates dedicated ECC encoder/decoder circuitry that detects and corrects single-bit errors on every read cycle without external logic. The Byte Power-down feature activates automatically when both BHE and BLE are deasserted, enabling sub-19 µA standby regardless of CE state.

It supports two memory configurations via BYTE pin control: 2M × 16 (BYTE = VCC) or 4M × 8 (BYTE = VSS), with A21 exposed only in the latter mode. Dual CE inputs (CE1/CE2) provide hierarchical chip select for multi-device systems, while TTL-compatible signaling ensures direct interfacing with legacy microcontrollers.

FAQ

Does CY62177G30-55BAXI support automatic error correction during read operations?

Yes. The device performs single-bit error detection and correction transparently on every read cycle using on-die ECC circuitry. No external logic or software intervention is required-the corrected data appears on the I/O bus, and no ERR pin assertion occurs (unlike CY62177GE30). This ensures silent, deterministic data integrity.

What is the function of the BYTE pin on CY62177G30-55BAXI?

The BYTE pin configures memory organization: tied to VCC, it operates as a 2M × 16 SRAM; tied to VSS, it becomes a 4M × 8 device with A21 enabled on pin 45. In 4M × 8 mode, BHE, BLE, and I/O8–I/O14 are unused and may be left floating-no pull-up/down required.

Can CY62177G30-55BAXI operate reliably at 2.2 V?

Yes. It is fully specified across 2.2 V to 3.6 V, including 55 ns access time, 19 µA max standby current, and ECC functionality at minimum VCC. DC and AC parameters are guaranteed over the full industrial temperature range (–40 °C to +85 °C) at 2.2 V.

Is the 48-pin TSOP I package RoHS-compliant and lead-free?

Yes. CY62177G30-55BAXI uses a Pb-free 48-pin TSOP I package compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3). The package marking "BAXI" denotes this Pb-free, industrial-grade variant.
