Infineon Technologies CY7C1069G30-10ZSXIT

Overview

CY7C1069G30-10ZSXIT from Cypress Semiconductor is a 16-Mbit (2M × 8) CMOS static RAM with embedded single-bit error-correcting code (ECC), TTL-compatible I/O, 10 ns access time, and dual chip enable (CE1/CE2) architecture. It operates across 2.2 V–3.6 V supply, draws 90 mA typical active current, and supports industrial temperature range (–40 °C to +85 °C). It is used in mission-critical embedded controllers where data integrity and deterministic timing are essential.

For engineers reviewing the CY7C1069G30-10ZSXIT datasheet, CY7C1069G30-10ZSXIT pinout, CY7C1069G30-10ZSXIT application, or CY7C1069G30-10ZSXIT equivalent, this page delivers verified functional identity, validated package mapping (54-pin TSOP II), confirmed ECC behavior, and real-world design implications for memory subsystems requiring fault-tolerant operation without external correction logic.

Technical Context

The device implements a synchronous, dual-chip-enable SRAM core with integrated ECC encoder/decoder that detects and corrects single-bit errors on every read access. Its ERR pin (active-high) signals correction events only on CY7C1069GE variants - the CY7C1069G30-10ZSXIT is a G-series part and does not include the ERR output.

It uses standard TTL-level input thresholds and drives TTL-compatible outputs, supports three V_CC ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V), and features automatic CE-based power-down modes yielding ISB2 = 20 mA typical standby current. Address space spans A0–A20 (21 bits), enabling full 2M-word addressing with 8-bit bidirectional I/Os (I/O0–I/O7).

FAQ

Does CY7C1069G30-10ZSXIT include an ERR output pin?

No. The CY7C1069G30-10ZSXIT is a G-series variant and does not feature the ERR output pin. That functionality is exclusive to GE-series parts like CY7C1069GE30-10ZSXIT. G-series devices perform ECC correction internally but provide no external indication of correction events.

What is the maximum clock frequency supported for burst reads?

This is an asynchronous SRAM and does not use a clock signal. Access timing is governed solely by t_AA (10 ns), t_OH (3 ns), and t_HZ (3 ns). Bus throughput is limited by external controller timing margins-not internal clocking-making it compatible with microcontrollers running up to 100 MHz with appropriate wait-state configuration.

Can CY7C1069G30-10ZSXIT operate at 1.8 V?

No. This specific variant is rated for 2.2 V–3.6 V operation only. The 1.65 V–2.2 V range applies exclusively to CY7C1069G18 and CY7C1069GE18 parts. Operating below 2.2 V risks timing violations and ECC functional failure per datasheet specifications.

Is the 54-pin TSOP II package pin-compatible with CY7C1069G18-15ZSXIT?

Yes-both share identical 54-pin TSOP II pinout and signal assignment per Figures 1 and 2 of datasheet 001-81539 Rev. *J. The only differences are speed grade (10 ns vs. 15 ns) and V_CC range; no PCB redesign is needed when upgrading from -15 to -10 speed within same voltage family.
