Infineon Technologies CY7S1061G30-10ZXIT

Overview

CY7S1061G30-10ZXIT from Infineon Technologies (formerly Cypress) is a 16-Mbit (1 M × 16) CMOS static RAM with embedded Error Correcting Code (ECC), PowerSnooze™ deep-sleep mode, and TTL-compatible I/O. It delivers 10 ns access time at 2.2–3.6 V, supports byte-level writes via BHE/ BLE, and features an ERR pin for single-bit error detection/correction-used in industrial control memory buffers requiring data integrity and ultra-low standby power.

For engineers reviewing the CY7S1061G30-10ZXIT datasheet, CY7S1061G30-10ZXIT pinout, CY7S1061G30-10ZXIT application, or CY7S1061G30-10ZXIT equivalent, key selection criteria include ECC-enabled reliability, 22 µA deep-sleep current, 10 ns tAA timing, multi-voltage support (2.2–3.6 V), and 48-ball VFBGA package compatibility with space-constrained embedded systems.

Technical Context

This SRAM implements a synchronous, non-volatile-retentive memory architecture with dedicated ECC logic that detects and corrects single-bit errors on read access without automatic write-back. The ERR pin asserts during correction events, enabling system-level fault logging.

PowerSnooze™ operation is controlled by the DS pin: asserting DS LOW disables all internal circuitry except retention latches, reducing ICC to ≤22 µA while preserving data at 1.0 V. Address and data I/Os are fully TTL-compatible across all supported VCC ranges, eliminating level-shifting requirements in mixed-voltage designs.

FAQ

Does CY7S1061G30-10ZXIT support automatic error correction write-back?

No. The device detects and corrects single-bit errors during read operations but does not perform automatic write-back to memory. The corrected data appears on I/O lines, and the ERR pin pulses to signal the event-leaving correction logging and recovery strategy to the host system firmware.

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

The device has no internal clock; it is asynchronous. Maximum sustained operation is determined by tCYC (cycle time), specified as 10 ns minimum for 2.2–3.6 V operation-enabling up to 100 MHz burst access when interfaced with appropriate address setup/hold timing from the controller.

Can the ERR pin be left unconnected if ECC functionality is unused?

Yes. The ERR pin is open-drain and inactive (high-impedance) when no correction occurs. If ECC monitoring is not required, the pin may be left floating or tied to VCC via a pull-up resistor-no functional impact on memory operation or power consumption.

Is the 48-ball VFBGA package of CY7S1061G30-10ZXIT compatible with standard reflow profiles?

Yes. The part is qualified for lead-free reflow per J-STD-020D, with peak temperature up to 260 °C and time above liquidus of 60–150 seconds. Its 0.5 mm ball pitch and 1.0 mm profile support standard Type III stencil printing and automated optical inspection.
