Product details
Overview
CY7C1041G30-10BAJXE from Infineon Technologies (formerly Cypress) is an AEC-Q100 qualified automotive-grade 4-Mbit static RAM with embedded ECC, organized as 256K × 16-bit, operating at 10 ns access time over –40 °C to +125 °C, with 2.2 V–3.6 V supply and TTL-compatible I/Os for use in engine control units and ADAS domain controllers.
For engineers reviewing the CY7C1041G30-10BAJXE datasheet, CY7C1041G30-10BAJXE pinout, CY7C1041G30-10BAJXE application, or CY7C1041G30-10BAJXE equivalent, key selection considerations include ECC-enabled single-bit error correction, automotive-E temperature support, 48-ball VFBGA package compatibility, and byte-level write enable via BHE/ BLE signals.
Technical Context
The CY7C1041G30-10BAJXE implements a full CMOS SRAM core with integrated ECC encoder/decoder logic that detects and corrects single-bit errors in real time without automatic write-back. It uses a single Chip Enable (CE) input and supports independent upper- and lower-byte writes via dedicated BHE and BLE controls.
Its timing architecture delivers guaranteed 10 ns tAA and tRC across the full automotive-E range, with HI-Z output control synchronized to OE, CE, BHE, and BLE transitions. The device maintains data retention down to 1.0 V and draws only 6 mA typical standby current (ISB2) under CMOS input conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4 Mbit (256K words × 16-bit), enabling compact storage for firmware scratchpad or sensor buffer in space-constrained ECUs |
| Access time (tAA) | 10 ns maximum, supporting real-time deterministic read response in safety-critical control loops |
| ECC capability | Embedded single-bit error correction per word, reducing uncorrectable error risk in radiation-prone vehicle environments |
| Operating voltage | 2.2 V–3.6 V, compatible with modern low-voltage automotive power domains including 2.5 V and 3.3 V rails |
| Temperature grade | Automotive-E: –40 °C to +125 °C, qualified for under-hood applications such as transmission control modules |
| Standby current (ISB2) | 6 mA typical at 3.6 V, minimizing quiescent power in always-on vehicle subsystems |
| Data retention voltage | 1.0 V minimum, allowing memory state preservation during brown-out or battery disconnect events |
Pinout & Package
Package: 48-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA), 6 mm × 8 mm, 0.5 mm pitch, RoHS-compliant and Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address inputs | 18-bit address bus supporting full 256K-word addressing; no internal multiplexing |
| I/O0–I/O15 | Bidirectional data lines | 16-bit parallel interface with TTL-compatible levels; all placed in HI-Z when CE, OE, BHE, or BLE are deasserted |
| CE | Chip Enable | Active-low global enable; device fully deselected and enters low-power mode when HIGH |
| OE | Output Enable | Active-low control for read data output; does not affect write path or ECC operation |
| WE | Write Enable | Active-low signal initiating write cycle; write completes on first rising edge of WE, CE, or byte enable |
| BHE | Byte High Enable | Active-low control for upper byte (I/O8–I/O15); enables partial writes without disturbing lower byte |
| BLE | Byte Low Enable | Active-low control for lower byte (I/O0–I/O7); supports independent 8-bit updates in mixed-data systems |
| VCC, VSS | Power and ground | Dual VCC pins improve noise immunity; multiple VSS balls reduce ground bounce in high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualification | Validated for automotive-E stress testing including HTOL, TC, and ESD, enabling direct use in ASIL-B systems without requalification |
| Embedded ECC logic | On-die Hamming-code encoder/decoder corrects single-bit errors per 16-bit word without external controller overhead or latency penalty |
| Low-power standby mode | ISB2 = 6 mA typical at 3.6 V ensures minimal current draw during sleep states in always-on telematics modules |
| TTL-compatible I/O | Direct interface with legacy microcontrollers and FPGAs without level-shifting, reducing BOM count and PCB area |
| Byte-select write architecture | Independent BHE/ BLE control allows efficient 8-bit updates in CAN message buffers or sensor register banks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61WV25616EDBLL-10MLI | No embedded ECC; requires external error handling; 10 ns access, same 256K × 16 organization | Suitable for non-safety-critical infotainment subsystems where ECC is managed in software | Select if system-level ECC is already implemented and cost sensitivity outweighs on-die reliability benefits |
| MT45W8MW16BGX-107 IT:A | DDR SDRAM, not SRAM; requires refresh circuitry; higher density but asynchronous interface complexity | Used in high-bandwidth display buffers where burst transfers justify DRAM overhead | Choose only when bandwidth > 100 MB/s is required and controller supports DDR initialization and refresh management |
Compared with IS61WV25616EDBLL-10MLI and MT45W8MW16BGX-107 IT:A, the CY7C1041G30-10BAJXE uniquely delivers hardware ECC, automotive-E qualification, and true zero-refresh SRAM behavior-critical for deterministic control applications where latency predictability and fault containment are mandatory.

FAQ
Does CY7C1041G30-10BAJXE support automatic error correction write-back?
No. The device performs single-bit error correction on read operations but does not automatically rewrite corrected data to the memory array. Error detection and correction occur transparently during read cycles, and corrected data is presented on I/O lines without modifying the stored value unless explicitly rewritten by the host system.
What is the SER FIT rate for CY7C1041G30-10BAJXE?
The soft error rate (SER) is specified as <0.1 FIT/Mb (failures-in-time per megabit), measured under terrestrial cosmic ray exposure conditions. This value is derived from accelerated neutron irradiation testing and documented in Application Note AN88889, confirming suitability for automotive safety-critical applications.
Can CY7C1041G30-10BAJXE operate at 2.5 V supply?
Yes. The device is fully specified across 2.2 V–3.6 V, including 2.5 V nominal rails. All AC and DC parameters-including 10 ns access time, 40 mA active current, and 6 mA standby current-are guaranteed at 2.5 V within the automotive-E temperature range (–40 °C to +125 °C).
Is the 48-ball VFBGA package lead-free and RoHS compliant?
Yes. The CY7C1041G30-10BAJXE uses a Pb-free, RoHS-compliant 48-ball VFBGA package with matte tin surface finish. Reflow profile follows JEDEC J-STD-020D for MSL3 handling, and moisture sensitivity level is rated at Level 3 per J-STD-033.
