Infineon Technologies CY7C1061GE-10ZSXIT

Overview

CY7C1061GE-10ZSXIT 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), delivers 10 ns access time, and supports industrial temperature (–40 °C to +85 °C) in a Pb-free 48-pin TSOP I package - used in mission-critical memory buffers for industrial controllers and telecom line cards.

For engineers reviewing the CY7C1061GE-10ZSXIT datasheet, CY7C1061GE-10ZSXIT pinout, CY7C1061GE-10ZSXIT application, or CY7C1061GE-10ZSXIT equivalent, key selection criteria include ECC-enabled data integrity, multi-voltage support, 10 ns tAA timing, ERR pin behavior during read cycles, and compatibility with legacy SRAM-based address/data bus architectures requiring byte-enable control (BHE/ BLE) and dual CE options.

Technical Context

This SRAM implements synchronous, non-volatile data retention at 1.0 V and uses dedicated hardware ECC logic that detects and corrects single-bit errors on-the-fly during read operations without CPU intervention. The ERR output asserts high only when a correctable error is found and corrected - no automatic write-back occurs, preserving deterministic latency.

It supports both single-CE (CE) and dual-CE (CE1/CE2) configurations, with BHE/ BLE enabling independent upper/lower byte writes to I/O[15:8] and I/O[7:0]. Address space spans A0–A19 (1 M words), and all I/Os enter high-Z when deselected or when OE/ BHE/ BLE are deasserted - critical for bus sharing in multi-peripheral systems.

Key Specifications

Pinout & Package

48-pin TSOP I (12 × 18.4 × 1 mm), Pb-free, industrial-grade package with standard pin pitch (0.5 mm). Pin 1 is located at bottom-left corner (marked by notch or dot); pin numbering proceeds counterclockwise.

FAQ

Does CY7C1061GE-10ZSXIT support automatic error correction write-back?

No. The device performs single-bit error detection and correction during read cycles but does not automatically write the corrected data back to memory. The corrected value appears on the I/O bus, and any write-back must be handled externally by the host system. This design preserves deterministic read latency and avoids unintended memory updates.

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 correctable single-bit error is detected and fixed during a read access. If unused, it must be left floating per datasheet guidance; if monitored, it requires an external pull-up resistor (typically 4.7 kΩ to VCC) to establish a valid logic HIGH level for interrupt or status reporting.

Can CY7C1061GE-10ZSXIT operate at 2.5 V supply?

No. The device supports only three discrete VCC ranges: 1.65–2.2 V, 2.2–3.6 V, and 4.5–5.5 V. Operation at 2.5 V falls outside all specified ranges and violates DC electrical characteristics - it may result in undefined behavior, timing violations, or accelerated wear. Use only within the defined bands.

How does the dual CE configuration differ from single CE in CY7C1061GE-10ZSXIT?

CY7C1061GE-10ZSXIT is the single-CE variant (pin 1 = CE). Dual-CE versions (e.g., CY7C1061GE-10ZSXI) use CE1 and CE2 pins whose logical AND defines chip select. This part has only one CE input, simplifying address decoding in systems with limited chip-select resources and eliminating dependency on CE1/CE2 timing alignment.
