Infineon Technologies CY7C1061G-10BVXIT

Overview

CY7C1061G-10BVXIT from Infineon Technologies (formerly Cypress) is a 16-Mbit (1M × 16-bit) CMOS static RAM with embedded single-bit error-correcting code (ECC), designed for high-reliability data storage in industrial control and telecom infrastructure. It operates at 10 ns access time, supports 1.65–2.2 V / 2.2–3.6 V / 4.5–5.5 V supply ranges, and features an ERR output pin for real-time single-bit error detection and correction during read cycles.

For engineers reviewing the CY7C1061G-10BVXIT datasheet, CY7C1061G-10BVXIT pinout, CY7C1061G-10BVXIT application, or CY7C1061G-10BVXIT equivalent, this device delivers deterministic ECC protection without automatic write-back, TTL-compatible I/Os, low standby current (20 mA typical), and dual chip enable support - critical for fault-tolerant memory subsystems in avionics data recorders, baseband processors, and programmable logic controllers.

Technical Context

The CY7C1061G-10BVXIT implements a synchronous SRAM architecture with dedicated ECC logic that computes and checks Hamming codes on every read access. Its ERR pin asserts high only when a correctable single-bit error is detected and corrected in the accessed 16-bit word - no action required from the host controller.

It supports byte-level writes via independent BHE (I/O8–I/O15) and BLE (I/O0–I/O7) controls, and offers three voltage-range options with corresponding speed grades: 10 ns at 2.2–3.6 V and 4.5–5.5 V, 15 ns at 1.65–2.2 V. The -10 suffix confirms 10 ns access time under specified VCC and temperature conditions.

FAQ

Does CY7C1061G-10BVXIT perform automatic write-back after ECC correction?

No. The device corrects single-bit errors during read operations and asserts the ERR pin, but does not automatically rewrite the corrected data back to the memory array. System firmware must initiate a separate 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 NC pins in the 48-ball VFBGA package?

NC (No Connect) pins - such as Ball A16 and Ball H6 in certain configurations - are physically present but not bonded to the silicon die. They serve mechanical or thermal roles only and must remain unconnected in PCB layout. The datasheet explicitly states "NC pins are not connected internally to the die" and warns against routing traces or applying voltage to them.

Can the ERR pin be left unconnected if ECC reporting is not used?

Yes. The ERR pin is an open-drain output and may be left floating if error indication is not monitored. However, the datasheet recommends leaving it unconnected rather than tying it LOW or to VCC, as improper termination could cause contention or false assertions. No pull-up resistor is required unless the host system needs to detect the ERR signal.

How does the dual CE architecture affect timing during bank selection?

For dual CE devices, CE is defined as the logical AND of CE1 (active-low) and CE2 (active-high). Access occurs only when CE1 = LOW and CE2 = HIGH. This configuration allows hierarchical decoding - e.g., CE1 driven by major address bits and CE2 by chip-select logic - without adding propagation delay beyond standard CE timing parameters (tCE, tCES).
