Infineon Technologies CY7C1061GE18-15BVJXI

Overview

CY7C1061GE18-15BVJXI from Infineon Technologies (formerly Cypress) is a 16-Mbit (1M × 16-bit) CMOS static RAM with embedded single-bit error-correcting code (ECC), operating at 1.65–2.2 V, tAA = 15 ns access time, and featuring an active ERR output pin for real-time ECC event indication. It supports dual chip enable (CE1/CE2), byte-level writes via BHE/ BLE, and is qualified for industrial temperature range (–40°C to +85°C).

For engineers reviewing the CY7C1061GE18-15BVJXI datasheet, CY7C1061GE18-15BVJXI pinout, CY7C1061GE18-15BVJXI application, or CY7C1061GE18-15BVJXI equivalent, this device is selected for high-reliability SRAM applications requiring on-die ECC, low standby current (ISB2 = 20 mA typ), TTL-compatible I/O, and 1.0 V data retention - especially where bit-flip resilience in safety-critical memory buffers is mandatory.

Technical Context

This SRAM implements a synchronous, addressable memory array with dedicated ECC logic that detects and corrects single-bit errors during read cycles without CPU intervention. The ERR pin asserts high only when correction occurs, enabling system-level fault logging without interrupt overhead.

It supports three VCC ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V) and offers configurable chip enable architecture: dual CE (CE1/CE2) logic enables hierarchical memory mapping, while BHE/ BLE pins allow independent upper- and lower-byte write control to I/O[15:8] and I/O[7:0], respectively.

FAQ

Does CY7C1061GE18-15BVJXI support automatic error correction write-back?

No. The device performs single-bit error correction only on read output - corrected data is not written back to the memory array. This avoids unintended overwrites and preserves original stored values for forensic analysis or redundancy validation in safety systems.

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

The ERR pin is an open-drain output that asserts high during successful single-bit correction. It must be externally pulled up to VCC via a 4.7 kΩ resistor. When unused, it may be left floating per datasheet Note 6, but active monitoring is recommended for fault logging in certified systems.

Can CY7C1061GE18-15BVJXI operate across all three VCC ranges simultaneously?

No. The device must be powered from one valid VCC range at a time: either 1.65–2.2 V, 2.2–3.6 V, or 4.5–5.5 V. Mixing voltages violates absolute maximum ratings and may cause latch-up or parametric failure. VCC selection determines speed grade (15 ns vs. 10 ns) and current consumption.

Is the BVJXI package pinout compatible with other CY7C1061GE variants?

Yes - BVJXI uses the 48-ball VFBGA with dual CE and ERR, and A19 at Ball G2. It shares identical pin mapping with CY7C1061GE18-15BV1XI (single CE) except CE2 and ERR placement; however, CE1/CE2 logic differs from single-CE CE pin behavior, requiring firmware or logic adaptation.
