Infineon Technologies CY7C1061GE-10BV1XI

Overview

CY7C1061GE-10BV1XI from Infineon Technologies (formerly Cypress) is a 16-Mbit (1M × 16-bit) CMOS static RAM with embedded single-bit error-correcting code (ECC), TTL-compatible I/O, and an active-high ERR output pin for real-time error indication. It operates across three voltage ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V), delivers 10 ns access time, and supports data retention at 1.0 V. It is used in industrial control modules requiring high-reliability memory with fault detection.

For engineers reviewing the CY7C1061GE-10BV1XI datasheet, CY7C1061GE-10BV1XI pinout, CY7C1061GE-10BV1XI application, or CY7C1061GE-10BV1XI equivalent, key selection criteria include ECC-enabled read integrity, dual-chip-enable support, 48-ball VFBGA (6 × 8 × 1.0 mm) package compatibility, and industrial-grade temperature range (–40 °C to +85 °C).

Technical Context

This SRAM implements on-die ECC logic that detects and corrects single-bit errors during read cycles, asserting the ERR pin high upon correction. The device uses standard asynchronous parallel interface timing with CE, OE, WE, BHE/ BLE controls - no clock required. Address space spans A0–A19 (1M words), with I/O0–I/O15 bidirectional data bus.

It supports both single-CE and dual-CE (CE1/CE2) configurations; for dual-CE operation, CE1 must be LOW and CE2 HIGH to enable. The ERR pin is dedicated output-only and floats when unused. Data retention at 1.0 V enables low-power suspend modes without data loss.

FAQ

Does CY7C1061GE-10BV1XI require external ECC circuitry?

No. It contains fully integrated hardware ECC logic that automatically detects and corrects single-bit errors during every read cycle. The ERR pin signals correction events, eliminating need for external syndrome generators, parity chips, or software-based correction routines. This reduces BOM count and simplifies validation for functional safety standards.

What is the function of the ERR pin, and how should it be interfaced?

The ERR pin is an open-drain, active-high output asserted for one clock cycle whenever a single-bit error is corrected. It must be pulled up externally (e.g., 4.7 kΩ to VCC) to generate a valid logic HIGH. Connect to an interrupt input on the host MCU to trigger diagnostic logging or fail-safe actions without polling overhead.

Can CY7C1061GE-10BV1XI operate at 2.5 V?

Yes. Its 2.2 V–3.6 V operating range includes 2.5 V. At this voltage, typical ICC is 90 mA at 100 MHz and ISB2 is 20 mA. All DC and AC specifications - including VOH/VOL, tAA = 10 ns, and ECC functionality - are fully guaranteed across the entire 2.2–3.6 V band per datasheet Section 7.

Is the 48-ball VFBGA (BV1XI) pinout compatible with other CY7C1061GE variants?

Yes - the BV1XI variant uses the same 48-ball VFBGA mechanical footprint and signal mapping as other BVxXI suffix parts, including identical A19 placement at ball G2 and ERR at ball D1. Pin compatibility is confirmed in Figures 4 and 7 of datasheet 001-81540 Rev. *T, enabling direct PCB reuse across speed/voltage grades.
