Infineon Technologies CY7C1061G30-10ZXET

Overview

CY7C1061G30-10ZXET from Cypress Semiconductor is an automotive-grade 16-Mbit (1 M × 16) 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 CY7C1061G30-10ZXET datasheet, CY7C1061G30-10ZXET pinout, CY7C1061G30-10ZXET application, or CY7C1061G30-10ZXET equivalent, key selection factors include ECC-enabled data integrity, dual-byte write control (BHE/ BLE), low ISB2 standby current (20 mA typical), and AEC-Q100 Grade 1 qualification for automotive electronics.

Technical Context

This SRAM implements on-die ECC encoding and decoding logic that detects and corrects single-bit errors during read cycles without automatic write-back-error correction occurs transparently in the data path before output buffer stage. The device uses asynchronous address-latched access with independent byte enables for true 8-bit sub-word writes.

It supports three power states: active (ICC = 90 mA typical @ 100 MHz), automatic CE-controlled standby (ISB2 = 20 mA), and 1.0-V data retention mode (ICC_DR ≤ 50 mA). 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.

Key Specifications

Pinout & Package

Available in 48-ball VFBGA (6 × 8 × 1.0 mm) and 48-pin TSOP I (12 × 18.4 × 1 mm) packages. Pin functions are identical across both packages; NC pins are unconnected internally.

FAQ

Does CY7C1061G30-10ZXET support automatic error correction during write operations?

No. The embedded ECC logic operates only during read cycles to detect and correct single-bit errors in the output data path. It does not perform write-time encoding or automatic write-back on error detection, as explicitly stated in the datasheet Note 1. Error correction is transparent and adds no latency to read access time.

What is the maximum clock frequency supported for burst reads using this SRAM?

This is an asynchronous SRAM with no internal clock input; it does not support burst reads. Maximum effective throughput is determined by tRC = 10 ns, enabling up to 100 million random accesses per second. Interface timing relies solely on CE, OE, and address setup/hold constraints-not a system clock.

Can BHE and BLE be used simultaneously to perform a full 16-bit write?

Yes. Asserting both BHE and BLE LOW while CE and WE are LOW enables full 16-bit write to the addressed location. The device treats simultaneous assertion as a standard word write-no conflict or undefined behavior occurs, and both byte lanes drive valid data concurrently.

Is the 48-ball VFBGA package RoHS and REACH compliant?

Yes. The CY7C1061G30-10ZXET in VFBGA packaging is Pb-free and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed in Cypress's official product change notices and material declarations dated 2016 onward.
