Infineon Technologies CY7C1062G30-10BGXI

Overview

CY7C1062G30-10BGXI from Cypress Semiconductor is a 16-Mbit (512 K × 32) CMOS static RAM with embedded single-bit error-correcting code (ECC), operating at 10 ns access time over 2.2 V–3.6 V supply, featuring TTL-compatible I/O, ERR pin for error indication, and automatic CE power-down. It serves in high-reliability industrial memory subsystems requiring data integrity assurance.

For engineers reviewing the CY7C1062G30-10BGXI datasheet, CY7C1062G30-10BGXI pinout, CY7C1062G30-10BGXI application, or CY7C1062G30-10BGXI equivalent, key selection criteria include ECC-enabled read/write latency, 119-ball PBGA thermal performance, byte-selectable 32-bit I/O architecture, and industrial-grade data retention at 1.0 V.

Technical Context

This SRAM integrates dedicated ECC encoder/decoder logic adjacent to the 512K × 32 memory array, enabling real-time single-bit error detection and correction on every read cycle without host intervention. The ERR output asserts high only when a correctable error is found - no automatic write-back occurs.

It employs three independent chip enables (CE1, CE2, CE3) and four byte enables (BA–BD) to support flexible memory expansion and partial-word access across 32-bit data bus segments. All I/O pins enter high-impedance state during deselect, OE high, byte disable, or write cycles.

FAQ

Does CY7C1062G30-10BGXI support automatic write-back after ECC correction?

No. The device detects and corrects single-bit errors during read operations and asserts the ERR pin, but it does not perform automatic write-back to the memory array. Host firmware must initiate a write cycle if persistent correction is required. This design avoids unintended bus contention and maintains strict timing predictability.

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. It must be externally pulled up to VCC via a 4.7 kΩ resistor. Leaving it floating is acceptable per datasheet Note 3, but active monitoring requires proper pull-up to generate a clean logic-high signal for host interrupt handling.

Can CY7C1062G30-10BGXI operate at 1.8 V?

No. This variant is rated only for 2.2 V to 3.6 V operation. The CY7C1062G18-15BGXI or CY7C1062GE18-15BGXI variants support 1.65 V–2.2 V operation. Attempting 1.8 V supply on the -30 suffix part violates its specified VCC range and may result in undefined timing or ECC functionality.

How many address lines does CY7C1062G30-10BGXI require?

It requires 19 address lines (A0–A18) to access its full 512 K-word depth. Each word is 32 bits wide, so no multiplexing or external address latching is needed for standard parallel interface implementations. The 119-ball PBGA package allocates dedicated pins for all address bits without sharing.
