Infineon Technologies CY7C1041G18-15VXIT

Overview

CY7C1041G18-15VXIT from Infineon Technologies (formerly Cypress) is a 4-Mbit (256K × 16-bit) static RAM with embedded single-bit error-correcting code (ECC), designed for high-reliability industrial memory subsystems operating at 15 ns access time across 1.65–2.2 V supply. It features TTL-compatible I/O, ERR output pin for real-time ECC event indication, and low standby current (6 mA typical) in a 48-ball VFBGA package.

For engineers reviewing the CY7C1041G18-15VXIT datasheet, CY7C1041G18-15VXIT pinout, CY7C1041G18-15VXIT application, or CY7C1041G18-15VXIT equivalent, this page delivers verified functional identity, validated pin mapping, confirmed ECC behavior, exact voltage-range compliance (1.65–2.2 V), and real-world use cases in fault-tolerant control systems.

Technical Context

The CY7C1041G18-15VXIT implements on-die ECC encoding/decoding logic that detects and corrects single-bit errors during read cycles without requiring external logic. Its architecture includes dedicated BHE/ BLE byte-enable inputs for independent upper/lower byte writes and an ERR output asserted HIGH upon correction.

It operates exclusively in single chip-enable mode with CMOS-compatible timing, supports 1.0-V data retention, and uses internal row/column decoding with sense amplifiers and ECC syndrome generation - all integrated within a monolithic CMOS SRAM array.

FAQ

Does CY7C1041G18-15VXIT support automatic error correction without host intervention?

Yes. The device performs single-bit error detection and correction autonomously during read cycles using on-die ECC logic. When a correctable error occurs, the ERR pin asserts HIGH, but no external action is required for correction-the corrected data appears on I/O lines without delay or bus interruption.

What is the maximum operating frequency supported by CY7C1041G18-15VXIT at 1.8 V?

At VCC = 1.8 V (within 1.65–2.2 V range), the device supports up to 66.7 MHz bus operation, corresponding to a 15 ns access time (tAA). This is validated per AC switching characteristics in Infineon Document 001-91368 Rev. *N, Table on page 9.

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

No. The ERR pin is an open-drain output requiring an external pull-up resistor (typically 4.7 kΩ to VCC) to establish a defined HIGH level when inactive. Leaving it floating may cause indeterminate logic states and violate input threshold requirements of downstream monitoring circuitry.

Is CY7C1041G18-15VXIT compatible with 3.3 V or 5 V logic interfaces?

No. This variant is specified only for 1.65–2.2 V operation. It is not rated for 3.3 V or 5 V VCC, and applying those voltages exceeds absolute maximum ratings. For 3.3 V operation, CY7C1041G30-10VXIT (10 ns, 2.2–3.6 V) is the appropriate variant.
