Infineon Technologies CY7C1061G18-15ZXIT

Overview

CY7C1061G18-15ZXIT from Infineon Technologies (formerly Cypress) is a 16-Mbit (1M × 16-bit) CMOS static RAM with embedded single-bit error-correcting code (ECC), rated for 15 ns access time, 1.65–2.2 V operation, and industrial temperature range (–40 °C to +85 °C). It features TTL-compatible I/Os, ERR output for error indication, and low standby current (20 mA typical), deployed in mission-critical memory subsystems requiring data integrity.

For engineers reviewing the CY7C1061G18-15ZXIT datasheet, CY7C1061G18-15ZXIT pinout, CY7C1061G18-15ZXIT application, or CY7C1061G18-15ZXIT equivalent, key selection criteria include ECC-enabled read reliability, dual-chip-enable support, TSOP I package compatibility, and voltage-flexible operation across 1.65–2.2 V, 2.2–3.6 V, and 4.5–5.5 V rails.

Technical Context

This SRAM implements on-die Hamming-code ECC logic that detects and corrects single-bit errors during read cycles without external circuitry. The ERR pin asserts high upon correction, enabling system-level fault logging and recovery. It supports byte-wide writes via independent BHE/ BLE controls and operates with either single CE or dual CE1/CE2 enable logic.

Its architecture separates address latching, data I/O buffering, and ECC syndrome generation into synchronous blocks synchronized to WE and OE timing. The device maintains data retention at 1.0 V and supports full-speed operation up to 100 MHz under 1.8 V supply, with guaranteed tAA = 15 ns at VCC = 1.8 V and TA = 85 °C.

FAQ

Does CY7C1061G18-15ZXIT support automatic error correction during read operations?

Yes. The device performs on-the-fly single-bit error detection and correction during every read cycle using embedded Hamming-code logic. Corrected data appears on I/O lines, and the ERR pin asserts high to indicate the event-no external logic or software intervention is required.

Can the ERR pin be left unconnected if error reporting is not needed?

Yes. The ERR pin is an open-drain output and may be left floating if unused. Infineon's datasheet explicitly states that unused ERR pins should not be tied to VCC or GND; floating operation avoids unintended current paths and preserves default high-impedance behavior.

What is the maximum clock frequency supported for continuous burst reads?

The device does not use a clock input; it is asynchronous. Maximum sustained data throughput is determined by tAA (15 ns) and cycle time tRC (25 ns). At 1.8 V, it supports up to 40 million 16-bit words per second in non-multiplexed parallel mode, limited by address setup/hold and output enable timing.

Is CY7C1061G18-15ZXIT compatible with legacy CY7C1061G designs using TSOP I packages?

Yes. The ZXIT suffix denotes the same 48-pin TSOP I footprint and pinout as earlier CY7C1061G variants. Electrical characteristics-including VCC range, timing, and I/O thresholds-are backward-compatible, allowing drop-in replacement in existing industrial PCB layouts without redesign.
