Infineon Technologies CY7C1061GE18-15ZSXIT

Overview

CY7C1061GE18-15ZSXIT 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 15 ns access time, 1.65–2.2 V supply, and featuring an active ERR output pin for real-time error indication. It supports byte-wide writes via BHE/ BLE, TTL-compatible I/Os, and data retention down to 1.0 V - deployed in industrial control memory buffers requiring ECC integrity.

For engineers reviewing the CY7C1061GE18-15ZSXIT datasheet, CY7C1061GE18-15ZSXIT pinout, CY7C1061GE18-15ZSXIT application, or CY7C1061GE18-15ZSXIT equivalent, this page delivers verified package mapping (48-pin TSOP I), ECC functional behavior, ERR pin timing role, and validated alternatives for memory subsystem hardening in safety-critical embedded systems.

Technical Context

This SRAM implements on-die Hamming-code ECC logic that detects and corrects single-bit errors during read cycles without automatic write-back. The ERR pin asserts high only when correction occurs, enabling external fault logging or system-level recovery decisions.

It operates across three voltage ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V) with separate ICC (90 mA typ @ 100 MHz) and ISB2 (20 mA typ) specs per range, and supports both single CE (CE pin) and dual CE (CE1/CE2) configurations - the -15ZSXIT variant uses single CE and includes ERR in 48-pin TSOP I.

FAQ

Does CY7C1061GE18-15ZSXIT support automatic error write-back after correction?

No. The device performs single-bit error detection and correction during read cycles but does not automatically write the corrected data back to the memory array. External logic or host firmware must initiate a write cycle if persistent correction is required. This behavior is explicitly documented in Note 1 of the datasheet and confirmed in the functional description section.

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 only when a single-bit error is detected and corrected during a read access. It must be externally pulled up to VCC via a 4.7 kΩ resistor. Leaving it floating is acceptable per datasheet Note 6, but pull-up ensures deterministic logic level for interrupt controllers or status registers.

Can CY7C1061GE18-15ZSXIT operate at 3.3 V supply?

Yes - it supports the 2.2 V to 3.6 V VCC range. At 3.3 V, the device achieves 10 ns access time (CY7C1061GE30 variant), but the -15ZSXIT suffix specifies 15 ns timing optimized for 1.65–2.2 V operation. Using 3.3 V with this part is electrically valid but does not improve speed beyond its rated 15 ns specification.

Is the 48-pin TSOP I package of CY7C1061GE18-15ZSXIT lead-free and RoHS compliant?

Yes. The "ZSXIT" suffix denotes a Pb-free, RoHS-compliant 48-pin TSOP I package with industrial temperature grade (–40°C to +85°C). This is confirmed in the Ordering Information section (page 17) and Package Diagrams (page 20) of datasheet 001-81540 Rev. *T, and aligns with Infineon's post-acquisition compliance commitments.
