Product details
Overview
CY7C1041G30-10ZSXA from Infineon Technologies (formerly Cypress) is an AEC-Q100 qualified automotive-grade 4-Mbit static RAM (256K × 16-bit) with embedded single-bit error-correcting code (ECC), 10 ns access time, and operation over –40 °C to +125 °C. It features TTL-compatible I/Os, 2.2–3.6 V supply range, and dual-byte write control via BHE/ BLE for safety-critical memory applications in engine control units and ADAS domain controllers.
For engineers reviewing the CY7C1041G30-10ZSXA datasheet, CY7C1041G30-10ZSXA pinout, CY7C1041G30-10ZSXA application, or CY7C1041G30-10ZSXA equivalent, key selection criteria include ECC implementation method, tAA = 10 ns timing under automotive temperature extremes, VFBGA-48 package thermal resistance (θJA = 30.68 °C/W), and CE/WE/OE/BHE/ BLE control logic compatibility with legacy SRAM-based microcontroller interfaces.
Technical Context
The CY7C1041G30-10ZSXA implements a dedicated on-die ECC encoder/decoder pair that detects and corrects single-bit errors per 16-bit word without external logic or software intervention. Its memory array uses CMOS fast-static architecture with row/column decoding and sense amplifiers optimized for low-latency random access.
Control logic supports three independent enable paths: Chip Enable (CE) for device selection, Output Enable (OE) for read data gating, and separate Byte High Enable (BHE) and Byte Low Enable (BLE) for granular 8-bit writes. All I/Os enter high-impedance state when CE is HIGH or OE/BHE/ BLE are deasserted - critical for bus sharing in multi-peripheral automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4 Mbit (256K words × 16-bit); supports full-word parallel access for real-time firmware execution buffers. |
| Access time (tAA) | 10 ns max at VCC = 3.6 V and TA = –40 °C to +125 °C; enables deterministic timing in safety-critical boot and diagnostic routines. |
| ECC capability | Embedded single-bit error correction per 16-bit word; reduces uncorrectable error rate to <0.1 FIT/Mb without host CPU overhead. |
| Supply voltage | 2.2 V to 3.6 V; compatible with automotive 3.3 V power rails and tolerant of battery transients down to 2.2 V. |
| Operating current | ICC = 40 mA typical at fMAX; enables low-power active mode in always-on vehicle subsystems. |
| Standby current | ISB2 = 6 mA typical with CE HIGH and CMOS inputs; supports extended sleep modes while retaining data integrity. |
| Data retention | 1.0 V minimum VCC for data hold; allows memory contents preservation during deep power-down events. |
Pinout & Package
Package: 48-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA), 6 mm × 8 mm, 0.5 mm pitch, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address inputs | 18-bit address bus supporting 256K-word addressing; A0–A17 directly map to memory location index with no internal multiplexing. |
| I/O0–I/O7 | Data bus (lower byte) | Bi-directional 8-bit data path controlled by BLE; used for LSB-aligned transfers in 16-bit or 8-bit configurations. |
| I/O8–I/O15 | Data bus (upper byte) | Bi-directional 8-bit data path controlled by BHE; enables independent upper-byte writes for packed data structures. |
| CE | Chip Enable | Active-LOW global select; must be LOW for any read/write cycle; supports automatic power-down when HIGH. |
| OE | Output Enable | Active-LOW read strobe; gates output drivers only - does not affect internal memory state or ECC operation. |
| WE | Write Enable | Active-LOW write strobe; initiates write when CE and BHE/ BLE are also asserted; controls write timing window. |
| BLE | Byte Low Enable | Active-LOW control for I/O0–I/O7; enables lower-byte write without affecting upper byte contents. |
| BHE | Byte High Enable | Active-LOW control for I/O8–I/O15; enables upper-byte write independently of lower byte. |
| VCC | Power supply | Primary 2.2–3.6 V core and I/O supply; two dedicated VCC balls ensure stable rail distribution across die. |
| VSS | Ground | Digital ground reference; multiple VSS balls minimize ground bounce during simultaneous byte writes. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade E qualification | Validated for –40 °C to +125 °C ambient operation with full electrical characterization across temperature and voltage corners. |
| Embedded ECC with SER FIT < 0.1 FIT/Mb | Hardware-level error detection and correction per 16-bit word; eliminates need for external ECC logic or software polling. |
| TTL-compatible I/O interface | VIH/VIL thresholds match legacy 3.3 V TTL levels; enables drop-in replacement in existing SRAM-based designs without level-shifting. |
| Low-power standby with 1.0 V data retention | Retains valid data at VCC = 1.0 V while drawing ≤14 mA; supports fail-safe memory hold during brown-out conditions. |
| Dual-byte write control (BHE/ BLE) | Independent enable signals for upper and lower bytes allow atomic 8-bit updates without read-modify-write cycles. |
Applications
| Engine Control Unit (ECU) Firmware Buffer | Advanced Driver Assistance Systems (ADAS) Sensor Cache |
|---|---|
Use Scenario: Stores real-time calibration tables and interrupt service routine context during engine start-stop cycles with frequent voltage dips. IC Role / Device Role / Timing Role: High-reliability SRAM buffer with ECC protection for volatile firmware execution space; provides deterministic 10 ns tAA under transient 2.2 V supply.

| Automotive Gateway Communication Stack | Electric Powertrain Inverter Control |
Use Scenario: Holds CAN FD message buffers and protocol state machines in telematics gateways operating continuously at 125 °C under hood conditions. IC Role / Device Role / Timing Role: Automotive-E grade SRAM with θJA = 30.68 °C/W; sustains full-speed operation without derating in thermally constrained gateway PCB layouts.

Use Value: Reduces diagnostic coverage requirements for memory faults by >90%, simplifying FMEDA analysis and certification evidence for ASIL-B decomposition. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive SRAM with ECC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61WV25616EDBLL-10BLI | No embedded ECC; requires external error detection logic or software-based correction. | Lacks hardware-level single-bit correction; increases ASIL compliance effort and CPU overhead. | Select only if ECC is implemented externally and thermal budget allows TSOP-II package (θJA = 66.82 °C/W). |
| MT48LC16M16A2P-6A:G | Synchronous SDRAM, not asynchronous SRAM; requires clock and refresh management. | Not pin-compatible; incompatible control protocol (CAS/RAS vs. CE/OE/WE); unsuitable for legacy SRAM interfaces. | Consider only for new designs with SDRAM controllers and tolerance for 60+ ns latency and refresh complexity. |
Compared with IS61WV25616EDBLL-10BLI and MT48LC16M16A2P-6A:G, the CY7C1041G30-10ZSXA delivers deterministic 10 ns access, integrated ECC, and AEC-Q100 Grade E qualification in a thermally efficient VFBGA package - making it the sole choice for retrofitting ECC into existing automotive SRAM sockets without redesigning timing or error-handling architecture.

FAQ
Does CY7C1041G30-10ZSXA support automatic error correction without host processor intervention?
Yes. The device performs single-bit error correction autonomously in hardware using on-die ECC encoder/decoder circuitry. No firmware or external logic is required to detect or correct errors - correction occurs transparently during read operations, and corrected data appears on I/O lines without CPU involvement.
What is the maximum junction temperature supported during continuous operation?
The CY7C1041G30-10ZSXA is rated for continuous operation up to +125 °C ambient temperature (Automotive-E grade). With θJA = 30.68 °C/W and maximum ICC = 50 mA at 3.6 V, calculated junction temperature rise is ≤1.53 °C under typical board conditions - well within the 150 °C absolute maximum rating.
Can BHE and BLE be asserted simultaneously for full 16-bit writes?
Yes. Asserting both BHE and BLE LOW enables full 16-bit writes to I/O0–I/O15. This configuration behaves identically to standard SRAM write operation and is fully supported in all timing modes defined in the datasheet, including WE-controlled and CE-controlled cycles.
Is the 48-ball VFBGA package lead-free and RoHS-compliant?
Yes. The CY7C1041G30-10ZSXA uses a Pb-free, RoHS-compliant VFBGA package with matte tin surface finish. It meets JEDEC J-STD-020D moisture sensitivity level 3 requirements and is qualified for reflow soldering per IPC/JEDEC J-STD-020.
