Cypress Semiconductor Corp CY7C1011G30-10ZSXA

Overview

CY7C1011G30-10ZSXA from Infineon Technologies (formerly Cypress) is an automotive-grade 2-Mbit (128K × 16-bit) CMOS static RAM with embedded single-bit error-correcting code (ECC), operating at 10 ns access time over –40 °C to +125 °C, supporting 2.2 V–3.6 V supply and TTL-compatible I/O for safety-critical memory subsystems in engine control units.

For engineers reviewing the CY7C1011G30-10ZSXA datasheet, CY7C1011G30-10ZSXA pinout, CY7C1011G30-10ZSXA application, or CY7C1011G30-10ZSXA equivalent, key selection factors include AEC-Q100 qualification, ECC implementation without automatic write-back, dual-byte enable (BHE/ BLE) control, and VFBGA48/TSOP II package compatibility in automotive-E temperature grade.

Technical Context

The CY7C1011G30-10ZSXA implements a synchronous SRAM architecture with dedicated ECC encoder/decoder logic adjacent to the 128K × 16-bit memory array, detecting and correcting single-bit errors on read paths only - no error injection or write-back capability. It uses a single Chip Enable (CE) with active-low assertion and supports byte-level writes via independent BHE (I/O8–I/O15) and BLE (I/O0–I/O7) controls.

Timing is governed by strict AC parameters including tAA = 10 ns (max), tACE = 10 ns (max), and tDOE = 4.5 ns (max), with all I/Os entering high-impedance state when CE is HIGH or OE/BHE/BLE are deasserted. Data retention operates down to 1.0 V at ambient temperatures up to 125 °C, with ISB2 = 6 mA typical standby current under CMOS input conditions.

FAQ

Does CY7C1011G30-10ZSXA support automatic error correction write-back?

No. The device performs single-bit error correction on read operations only and does not automatically rewrite corrected data to memory. Error detection flags are not exposed externally, and no write-back mechanism is implemented in hardware or firmware.

What is the maximum operating frequency supported by CY7C1011G30-10ZSXA?

The device does not operate on a clock signal. Its maximum effective throughput is determined by tRC = 10 ns, enabling up to 100 million random accesses per second in ideal conditions with zero wait states and proper bus timing alignment.

Can CY7C1011G30-10ZSXA be used in industrial applications outside automotive?

Yes. While qualified to AEC-Q100 Grade 0, its –40 °C to +125 °C operating range, 2.2 V–3.6 V supply, and ECC functionality make it suitable for industrial motor drives, medical imaging buffers, and railway signaling systems requiring high-reliability SRAM.

Is the 48-ball VFBGA package of CY7C1011G30-10ZSXA compatible with standard reflow profiles?

Yes. The package complies with JEDEC J-STD-020D moisture sensitivity level 3 and supports standard lead-free reflow profiles with peak temperature ≤260 °C, ramp rates ≤3 °C/s, and time above liquidus of 60–150 seconds.
