Product details
Overview
CY7C1041GE-10ZSXIT from Infineon Technologies (formerly Cypress) is a 4-Mbit (256K × 16-bit) CMOS static RAM with embedded single-bit error-correcting code (ECC), TTL-compatible I/O, 10 ns access time, and dedicated ERR output pin for real-time error detection/correction - deployed in industrial-grade memory subsystems requiring data integrity in avionics control units, medical imaging buffers, and telecom baseband processors.
For engineers reviewing the CY7C1041GE-10ZSXIT datasheet, CY7C1041GE-10ZSXIT pinout, CY7C1041GE-10ZSXIT application, or CY7C1041GE-10ZSXIT equivalent, key selection criteria include ECC-enabled reliability at 1.65–3.6 V or 4.5–5.5 V operation, 6 mA typical standby current, 44-pin TSOP II package compatibility, and ERR pin behavior during read-cycle correction events.
Technical Context
The CY7C1041GE integrates on-die ECC encoding/decoding logic that detects and corrects single-bit errors in real time during read operations without external circuitry; correction occurs transparently, and the ERR pin asserts HIGH to signal successful correction. It supports byte-level writes via independent BHE and BLE controls for upper/lower 8-bit lanes.
Its dual-voltage architecture enables operation across three distinct VCC ranges: 1.65–2.2 V (15 ns speed grade), 2.2–3.6 V (10 ns), and 4.5–5.5 V (10 ns); all variants maintain 1.0-V data retention and TTL-compatible input thresholds. The device uses a single chip-enable (CE) architecture with no separate output-enable polarity inversion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4 Mbit (256K words × 16-bit) - provides 512 KB of parallel-access SRAM with full word-wide I/O bandwidth. |
| Access Time (tAA) | 10 ns - guarantees sub-100 MHz synchronous bus timing margin for high-speed microcontroller or FPGA interfaces. |
| ECC Function | Embedded single-bit error correction with ERR output assertion - eliminates need for external ECC logic in safety-critical memory paths. |
| Supply Voltage Ranges | 1.65–2.2 V, 2.2–3.6 V, and 4.5–5.5 V - supports legacy 5 V systems and modern low-voltage SoC coexistence without level shifters. |
| Standby Current (ISB2) | 6 mA typical - enables low-power hold mode in battery-backed instrumentation and portable diagnostic equipment. |
| Data Retention Voltage | 1.0 V - ensures nonvolatile data preservation during brown-out conditions or controlled power-down sequences. |
| I/O Compatibility | TTL-compatible inputs/outputs - simplifies integration with 3.3 V or 5 V microprocessors without interface translation. |
Pinout & Package
Package: 44-pin TSOP II (Type II, 400 mil width), Pb-free, industrial temperature grade (–40 °C to +85 °C), JEDEC MO-141AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CE | Chip Enable (active-low) | Primary device select; places all I/Os in high-impedance state when deasserted, enabling multi-chip memory expansion. |
| /OE | Output Enable (active-low) | Controls read-data output gating; allows shared bus operation with other peripherals when disabled. |
| /WE | Write Enable (active-low) | Initiates write cycle; combined with /CE and byte enables, defines valid write window timing. |
| /BHE | Byte High Enable | Enables write/read access to I/O8–I/O15 only - supports 8-bit peripheral interfacing on 16-bit buses. |
| /BLE | Byte Low Enable | Enables write/read access to I/O0–I/O7 only - enables mixed-width data transfers without software masking. |
| ERR | Error Report Output | Open-drain output asserted HIGH during single-bit correction event - used for fault logging or system-level error handling. |
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word addressing; A17 is MSB for 4-Mbit capacity. |
| I/O0–I/O15 | Bidirectional Data Bus | 16-bit parallel data path; tri-stated automatically during deselect, write, or byte-disable conditions. |
Key Features
| Feature | Design Value |
|---|---|
| On-die ECC engine | Corrects single-bit errors in real time during reads; no CPU overhead or external logic required. |
| Multi-range voltage support | Operates natively across 1.65–2.2 V, 2.2–3.6 V, and 4.5–5.5 V rails - reduces BOM count in mixed-voltage systems. |
| ERR output signaling | Dedicated open-drain pin indicates correction event with precise timing alignment to read cycle completion. |
| Low-power standby mode | 6 mA typical ISB2 current at VCC = 3 V - extends uptime in always-on edge nodes and remote sensors. |
| Byte-select write control | Independent /BHE and /BLE enable partial-word writes without read-modify-write cycles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECC SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61WV25616EDBLL-10MLI | No integrated ECC; requires external error-handling logic; 10 ns access, 2.5 V only; 48-ball TFBGA. | Lacks hardware error reporting; suitable for cost-sensitive designs where ECC is implemented in firmware or FPGA. | Select when board space permits external logic and functional safety certification is not required. |
| AS6C4008-10TIN | 4-Mbit × 8-bit organization; no ECC; 10 ns; 3.3 V only; 32-pin SOJ; higher standby current (15 mA). | Half the data bus width; requires two devices for 16-bit interface; no error resilience capability. | Choose only for legacy 8-bit bus upgrades where ECC is unnecessary and footprint constraints favor SOJ. |

FAQ
Does CY7C1041GE-10ZSXIT support automatic error correction during write cycles?
No. The device performs single-bit error correction only during read operations. Write cycles do not trigger ECC encoding or correction; the ERR pin remains inactive during writes. Error detection and correction occur exclusively on read data retrieved from the memory array, as confirmed in the functional description and truth table of datasheet Rev. *N.
What is the function of the ERR pin, and how is it electrically driven?
The ERR pin is an open-drain output that asserts HIGH (pulled up externally) when a single-bit error is detected and corrected during a read cycle. It remains LOW otherwise. No internal pull-up is provided; a 4.7 kΩ external resistor to VCC is required per datasheet recommendations to ensure clean logic-level signaling.
Can CY7C1041GE-10ZSXIT operate reliably at 1.8 V with 10 ns access time?
No. At 1.65–2.2 V, the device is rated for 15 ns access time (CY7C1041G(E)18 speed grade). The 10 ns rating applies only to the 2.2–3.6 V and 4.5–5.5 V voltage ranges. Operating at 1.8 V with tAA = 10 ns violates the specified speed grade and may result in timing violations or data corruption.
Is the 44-pin TSOP II package of CY7C1041GE-10ZSXIT RoHS-compliant and lead-free?
Yes. The "Z" in the part number suffix denotes Pb-free (lead-free) construction, and the device complies with RoHS Directive 2011/65/EU. The TSOP II package uses matte tin terminations and meets JEDEC standard J-STD-020 moisture sensitivity level 3 (MSL-3) for surface-mount assembly.
