Infineon Technologies CY7C1011G30-12ZSXET

Overview

CY7C1011G30-12ZSXET from Infineon Technologies (formerly Cypress) is an AEC-Q100 qualified automotive-grade 2-Mbit static RAM with embedded ECC, organized as 128K × 16-bit, operating at 12 ns access time over –40 °C to +125 °C, supporting 2.2 V–3.6 V supply and delivering 40 mA typical active current for safety-critical memory buffering in engine control units.

For engineers reviewing the CY7C1011G30-12ZSXET datasheet, CY7C1011G30-12ZSXET pinout, CY7C1011G30-12ZSXET application, or CY7C1011G30-12ZSXET equivalent, key selection criteria include ECC-enabled single-bit error correction, TSOP II package compatibility, automotive temperature grade E, low 6 mA standby current, and TTL-compatible I/O interface timing.

Technical Context

This SRAM implements a synchronous, single-cycle read/write architecture with dedicated Byte High Enable (BHE) and Byte Low Enable (BLE) inputs for independent upper/lower byte access, enabling efficient 8-bit data transfers within 16-bit memory maps. The ECC logic operates transparently during all read cycles, detecting and correcting single-bit errors without CPU intervention.

It features dual power-down modes: ISB1 (TTL input thresholds) and ISB2 (CMOS input thresholds), with ISB2 = 6 mA typical at 3.6 V, and supports 1.0-V data retention. All I/Os enter high-impedance state when CE is HIGH or OE/BHE/ BLE are deasserted, ensuring clean bus isolation in multi-device systems.

FAQ

Does CY7C1011G30-12ZSXET support automatic error correction during reads without CPU intervention?

Yes. The embedded ECC logic automatically detects and corrects single-bit errors on every read access. No software overhead or CPU cycle consumption is required-the corrected data appears directly on the I/O bus. However, it does not perform automatic write-back on error detection, as noted in the datasheet footnote 1.

What is the maximum clock frequency supported for continuous read/write bursts?

CY7C1011G30-12ZSXET has no internal clock; it is an asynchronous SRAM. Its maximum effective throughput is determined by tRC = 12 ns, enabling up to ~83.3 MHz sustained random access. For burst transfers, timing depends on address/data setup/hold margins relative to CE/OE/WE edges-not a fixed clock rate.

Can CY7C1011G30-12ZSXET operate reliably at 2.2 V across the full –40 °C to +125 °C range?

Yes. The datasheet specifies full DC and AC functionality-including tAA = 12 ns and ISB2 ≤ 14 mA-at 2.2 V minimum supply across Automotive-E temperature range. This is validated per AEC-Q100 stress testing and reflected in the Operating Range table on page 4.

Is the 44-pin TSOP II package of CY7C1011G30-12ZSXET pin-compatible with legacy CY7C1011 series devices?

Yes. The 44-pin TSOP II pinout matches CY7C1011DV33-10ZSXI and CY7C1011DN33-10ZSXI, including identical A0–A16, I/O0–I/O15, CE, OE, WE, BHE, BLE, VCC, and VSS placements. NC pins are consistent, and timing parameters are backward-compatible at same speed grade.
