Product details
Overview
CY7C1069G-10ZSXI 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 three voltage ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V), supports 1.0-V data retention, and delivers 90 mA typical active current at 100 MHz - used in mission-critical industrial control memory buffers requiring ECC integrity.
For engineers reviewing the CY7C1069G-10ZSXI datasheet, CY7C1069G-10ZSXI pinout, CY7C1069G-10ZSXI application, or CY7C1069G-10ZSXI equivalent, key selection criteria include verified ECC correction behavior, TSOP II package pin mapping, dual CE timing compatibility, and multi-voltage supply support for legacy and low-power systems.
Technical Context
This SRAM implements a synchronous, non-volatile-retention-capable memory array with dedicated ECC encoder/decoder logic that detects and corrects single-bit errors on read access without host intervention. The ERR signal is absent in CY7C1069G variants (including -10ZSXI), distinguishing it from CY7C1069GE devices.
It uses transistor-transistor logic (TTL)-compatible input thresholds and output drive strength, supports high-impedance tri-state I/O during deselect, write, or OE-high conditions, and features automatic CE-based power-down modes (ISB2 = 20 mA typical) across all supported VCC ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Mbit (2,097,152 words × 8 bits) - provides byte-wide addressing for microcontroller boot buffers and real-time data logging. |
| Access Time (tAA) | 10 ns - enables direct interface with 100 MHz bus systems without wait states. |
| VCC Range | 4.5–5.5 V, 2.2–3.6 V, and 1.65–2.2 V - supports mixed-voltage board designs and legacy 5 V, modern 3.3 V, and ultra-low-power 1.8 V domains. |
| Active Current (ICC) | 90 mA typical at 100 MHz - defines thermal budget for dense memory subsystems in industrial PLCs. |
| Standby Current (ISB2) | 20 mA typical - ensures low power consumption during idle cycles in always-on edge controllers. |
| Data Retention Voltage | 1.0 V - allows memory state hold during brown-out or controlled power-down sequences. |
| ECC Function | Single-bit error detection and correction per 8-bit word - eliminates soft-error-induced crashes in radiation-prone environments. |
Pinout & Package
The CY7C1069G-10ZSXI is packaged in a 54-pin TSOP II (Thin Small Outline Package, Type II) with center power/ground pinout configuration, optimized for high-density PCB layouts and thermal dissipation in industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | 21-bit address bus supporting full 2M-word decoding; A20 enables highest address bit selection. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface with TTL-compatible levels; high-impedance when CE1 HIGH, CE2 LOW, or OE HIGH. |
| CE1, CE2 | Dual Chip Enable Inputs | Active-LOW CE1 and active-HIGH CE2 form logical AND enable; enables selective bank activation in multi-SRAM systems. |
| WE | Write Enable Input | Active-LOW control for write operations; forces I/O pins to input mode during write cycles. |
| OE | Output Enable Input | Active-LOW control for read operations; disables outputs (high-Z) when deasserted, preventing bus contention. |
| VCC, VSS | Power Supply Pins | Multiple VCC/VSS pins distributed across package for low-impedance power delivery and reduced noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC Logic | Hardware-accelerated single-bit error correction per 8-bit word without CPU overhead or external logic. |
| Dual Chip Enable Architecture | Independent CE1/CE2 control enables flexible memory banking and reduces address decoder complexity. |
| TTL-Compatible I/O | Direct interface with legacy microcontrollers and FPGAs without level-shifting circuitry. |
| Multi-Voltage Operation | Three discrete VCC ranges allow drop-in replacement across 5 V, 3.3 V, and 1.8 V system generations. |
| Low-Power Standby Mode | ISB2 = 20 mA typical enables energy-efficient operation in battery-backed or intermittent-use applications. |
Applications
| Industrial PLC Memory Buffer | Military Avionics Data Logging |
|---|---|
|
Use Scenario: Real-time I/O status buffering in programmable logic controllers with deterministic scan cycle timing. IC Role / Device Role / Timing Role: Byte-wide SRAM acting as volatile working memory for ladder logic execution and register mirroring. Use Value: 10 ns tAA ensures zero-wait-state access for 100 MHz backplane buses; ECC prevents spurious fault triggers from cosmic-ray-induced bit flips. |
Use Scenario: Capturing sensor telemetry during flight-critical avionics health monitoring. IC Role / Device Role / Timing Role: High-reliability scratchpad memory for transient data before CRC-verified flash storage. Use Value: 1.0-V data retention sustains memory contents during brief power interruptions; ISB2 = 20 mA minimizes standby drain in battery-limited platforms. |
| Railway Signaling Controller | Medical Diagnostic Imaging Buffer |
|
Use Scenario: Storing interlocking logic states in EN 5012x-compliant railway signaling hardware. IC Role / Device Role / Timing Role: Safety-critical RAM holding fail-safe control flags and route validation tables. Use Value: Dual CE architecture isolates memory banks during hot-swap maintenance; ECC meets SIL-2 functional safety requirements for memory integrity. |
Use Scenario: Temporary frame storage in portable ultrasound or X-ray image acquisition units. IC Role / Device Role / Timing Role: High-speed pixel buffer between ADC front-end and JPEG compression engine. Use Value: TTL-compatible I/O interfaces directly with legacy imaging ASICs; 4.5–5.5 V operation matches standard medical power rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM with ECC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS61WV20488BLL-10MLI | No embedded ECC; requires external Hamming logic or software correction. | Suitable only where ECC is implemented at system level or not required. | Select if cost sensitivity outweighs ECC assurance and board space permits external logic. |
| Microchip 23LCV1024-I/P | Serial SPI interface (not parallel); 1 Mbit density; no ECC. | Used in space-constrained, low-pin-count MCU designs where serial bandwidth suffices. | Choose only for new designs accepting serial latency and lower density; not a drop-in replacement. |
Compared with IS61WV20488BLL-10MLI and 23LCV1024-I/P, CY7C1069G-10ZSXI uniquely delivers integrated hardware ECC, parallel 8-bit bus timing, and multi-voltage flexibility - making it irreplaceable in deterministic, safety-aware industrial memory subsystems.

FAQ
Does CY7C1069G-10ZSXI support automatic error correction without host processor involvement?
Yes. The device performs single-bit error detection and correction transparently during read operations using on-die ECC logic. No host firmware or external circuitry is required - corrected data appears on I/O pins with no latency penalty or interrupt generation.
What is the difference between CY7C1069G and CY7C1069GE variants?
CY7C1069G (including -10ZSXI) lacks the ERR output pin; CY7C1069GE adds an active-HIGH ERR signal that asserts when a single-bit error is detected and corrected. The core ECC function is identical, but only GE versions provide visible error indication.
Can CY7C1069G-10ZSXI operate at 2.5 V supply?
No. The device supports only three discrete VCC ranges: 1.65–2.2 V, 2.2–3.6 V, and 4.5–5.5 V. A 2.5 V supply falls within the 2.2–3.6 V range and is fully supported, with ICC = 90 mA typical at 100 MHz and tAA = 10 ns guaranteed.
Is the 54-pin TSOP II package RoHS-compliant and lead-free?
Yes. The "Z" suffix in -10ZSXI denotes a lead-free (Pb-free), RoHS-compliant 54-pin TSOP II package. Cypress confirms compliance with JEDEC J-STD-020 moisture sensitivity level 3 and IPC/JEDEC J-STD-033 handling requirements.
