Infineon Technologies CY7C1061GE18-15BVXIT

Overview

CY7C1061GE18-15BVXIT 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 ERR output signaling correction events. It operates across three voltage ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V), supports 15 ns access time, and delivers 90 mA typical active current at 100 MHz - deployed in industrial control modules requiring data integrity under extended temperature cycling.

For engineers reviewing the CY7C1061GE18-15BVXIT datasheet, CY7C1061GE18-15BVXIT pinout, CY7C1061GE18-15BVXIT application, or CY7C1061GE18-15BVXIT equivalent, key selection criteria include ECC-enabled reliability for mission-critical memory buffers, dual-chip-enable support for multi-bank addressing, 1.0 V data retention capability, and compatibility with legacy 48-ball VFBGA footprint designs.

Technical Context

This SRAM implements on-die ECC logic that detects and corrects single-bit errors during read cycles without automatic write-back, signaled via the dedicated ERR output pin asserted high. Its architecture supports byte-level writes using BHE/ BLE controls and full 16-bit parallel I/O access via I/O0–I/O15.

The device offers three selectable V_CC operating ranges with corresponding speed grades: 15 ns at 1.65–2.2 V, 10 ns at 2.2–3.6 V and 4.5–5.5 V. Standby current is minimized to 20 mA typical in ISB2 mode, and it maintains data retention down to 1.0 V - enabling low-power hold states in battery-backed systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar SRAM-with-ECC applications.

Compared with CY7C1061GE18-15BVXIT, the ISSI part lacks on-die ECC and demands external fault management, while the Microchip SPI SRAM trades parallel throughput and ECC for pin count reduction - neither matches the combination of 16-Mbit density, 15 ns access, and hardware ECC in a VFBGA package.

FAQ

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

No. The device detects and corrects single-bit errors during read operations and asserts the ERR pin, but does not perform automatic write-back to the memory array. System firmware must handle any required corrective writes if persistent error logging or proactive scrubbing is needed.

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

The ERR pin is an open-drain output that goes HIGH when a single-bit error is detected and corrected during a read cycle. It must be externally pulled up to V_CC with a 4.7 kΩ resistor to generate a valid logic HIGH signal usable for interrupt generation or status monitoring.

Can CY7C1061GE18-15BVXIT operate across all three voltage ranges simultaneously?

No. The device must be powered within one of the three specified V_CC ranges (1.65–2.2 V, 2.2–3.6 V, or 4.5–5.5 V) at a time. Voltage range selection determines maximum operating frequency and timing parameters - mixing ranges is not supported and may cause functional failure.

Is the 48-ball VFBGA package of CY7C1061GE18-15BVXIT compatible with CY7C1061G variants?

Yes - mechanical and pinout compatibility is maintained across CY7C1061G and CY7C1061GE variants in the same package type (e.g., BVXIT). However, the ERR pin is present only on GE versions; on G variants, that ball is designated NC and must remain unconnected.
