Product details
Overview
CY7C1041GE-10VXI from Infineon Technologies (formerly Cypress) is a 4-Mbit (256K × 16-bit) CMOS static RAM with embedded single-bit error-correcting code (ECC), operating at 10 ns access time across 1.65–2.2 V, 2.2–3.6 V, or 4.5–5.5 V supply ranges. It features an active ERR output pin for real-time ECC event indication and supports byte-level writes via BHE/ BLE control. Used in industrial embedded controllers requiring data integrity under radiation-prone or long-term reliability conditions.
For engineers reviewing the CY7C1041GE-10VXI datasheet, CY7C1041GE-10VXI pinout, CY7C1041GE-10VXI application, or CY7C1041GE-10VXI equivalent, this page delivers verified package mapping (48-ball VFBGA, BVXI grade), confirmed ECC behavior (single-bit correction with ERR assertion), true standby current (6 mA typical), and functional distinction from non-ERR CY7C1041G variants.
Technical Context
This SRAM integrates dedicated ECC encoder/decoder circuitry within the memory array path, enabling automatic detection and correction of single-bit errors during read cycles without CPU intervention. The ERR pin asserts HIGH only upon successful correction - not on uncorrectable multi-bit errors - and does not trigger automatic write-back.
It operates in single chip-enable mode with TTL-compatible I/Os, supports independent high- and low-byte write enables (BHE/BLE), and places all 16 I/O lines in high-impedance state when CE is HIGH or OE/BHE/BLE are deasserted. Data retention is guaranteed at 1.0 V down to –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4 Mbit (256K words × 16-bit); provides 512 KB of word-addressable storage with ECC protection per 16-bit word. |
| Access time (tAA) | 10 ns max at VCC = 2.2–3.6 V or 4.5–5.5 V; defines minimum cycle time for reliable read/write in high-speed control loops. |
| ECC capability | Single-bit error correction with ERR output assertion; detects and corrects bit flips in stored data without software overhead. |
| Supply voltage ranges | 1.65–2.2 V, 2.2–3.6 V, and 4.5–5.5 V; enables drop-in use across legacy 5 V, modern 3.3 V, and ultra-low-power 1.8 V systems. |
| Standby current (ISB2) | 6 mA typical at VCC = 3 V and TA = 25°C; ensures low power consumption during idle states in battery-backed or energy-sensitive designs. |
| Operating temperature | –40°C to +85°C (Industrial grade); validated for continuous operation in motor drives, PLCs, and telecom line cards. |
| Data retention voltage | 1.0 V minimum; guarantees non-volatile data hold during brown-out or controlled power-down sequences. |
Pinout & Package
Package: 48-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA), 6 mm × 8 mm × 1.0 mm, JEDEC-compliant BVXI grade (pinout matches Figure 2 in datasheet Rev. *N).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address inputs | 18-bit address bus supporting full 256K-word addressing; A0–A17 decoded internally for row/column selection. |
| I/O0–I/O15 | Bidirectional data bus | 16-bit parallel interface; high-impedance when CE HIGH or OE/BHE/BLE deasserted; supports byte-wide access. |
| CE | Chip Enable | Active LOW enable; disables all outputs and reduces current to ISB2 level when HIGH. |
| OE | Output Enable | Active LOW control for read data output; must be LOW with CE LOW to drive I/Os. |
| WE | Write Enable | Active LOW signal initiating write cycle; latches data on I/O0–I/O15 into addressed location. |
| BHE | Byte High Enable | Active LOW control for upper byte (I/O8–I/O15); allows selective 8-bit writes to high byte only. |
| BLE | Byte Low Enable | Active LOW control for lower byte (I/O0–I/O7); enables independent 8-bit writes to low byte only. |
| ERR | Error indication output | Open-drain output asserted HIGH during successful single-bit ECC correction; requires external pull-up. |
| VCC / VSS | Power / Ground | Dual VCC pins (balls C4, D3) and multiple VSS balls (C3, D4, E3, F3, G4) ensure low-noise power delivery and signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC engine | Hardware-based single-bit error correction with no CPU overhead; ERR pin signals correction events in real time. |
| Multi-voltage operation | Three discrete VCC ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V) allow reuse across 1.8 V microcontrollers, 3.3 V FPGAs, and legacy 5 V systems. |
| Byte-selective write control | BHE and BLE pins enable independent 8-bit writes without masking logic or additional glue logic. |
| Low-power standby mode | ISB2 = 6 mA typical at 3 V enables extended operation in power-constrained industrial gateways and edge nodes. |
| 1.0 V data retention | Guaranteed data hold at 1.0 V supply supports graceful shutdown and brown-out recovery in safety-critical firmware. |

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 Hamming logic or processor-based correction; 10 ns access, 256K × 16-bit, 3.3 V only. | Lacks hardware ERR signal; increases firmware complexity and latency for error handling. | Select only if system already implements software ECC and cost sensitivity outweighs reliability risk. |
| AS6C4008-10TIN | 4-Mbit (512K × 8-bit) SRAM with no ECC; 10 ns access, 2.7–3.6 V; SOJ-32 package. | Byte-wide architecture limits bandwidth vs. 16-bit CY7C1041GE; no error detection capability. | Use only in non-critical buffering where ECC is handled upstream or omitted entirely. |
Compared with IS61WV25616EDBLL-10MLI and AS6C4008-10TIN, CY7C1041GE-10VXI uniquely delivers hardware-accelerated ECC with visible correction feedback (ERR), multi-voltage support, and industrial-grade thermal performance - making it the sole choice for safety-aware, long-lifecycle embedded memory.

FAQ
Does CY7C1041GE-10VXI support automatic write-back after ECC correction?
No. The device performs single-bit error correction during read cycles and asserts the ERR pin, but does not automatically rewrite corrected data to the memory array. External logic or firmware must initiate a write cycle if persistent correction is required. This behavior is explicitly documented in Note 1 of the datasheet.
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 during successful single-bit ECC correction. It requires an external pull-up resistor (typically 4.7 kΩ to VCC) to generate a valid logic HIGH. It remains LOW during normal reads and uncorrectable errors, providing unambiguous status for diagnostic logging.
Can CY7C1041GE-10VXI operate at 2.5 V supply?
Yes. The device supports the 2.2 V–3.6 V VCC range, and 2.5 V falls within specification. Electrical characteristics (e.g., tAA ≤ 10 ns, ICC ≤ 45 mA) are guaranteed across this full range, with typical values measured at 3.0 V per datasheet Note 4.
How does the BVXI package differ from BVJXI for CY7C1041GE?
BVXI and BVJXI are both 48-ball VFBGA packages, but BVJXI swaps the physical ball positions of I/O[7:0] and I/O[15:8] relative to BVXI. This requires PCB layout revision - they are not pin-compatible. BVXI is used for CY7C1041GE-10VXI; BVJXI appears in alternate ordering codes per datasheet Figure 4.
