Product details
Overview
CY7C1069G-10ZSXIT from Cypress Semiconductor is a 16-Mbit (2M × 8) CMOS static RAM with embedded single-bit error-correcting code (ECC), dual chip enable (CE1/CE2) control, 10 ns access time, and TTL-compatible I/Os. 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 features an ERR pin for error indication in the CY7C1069GE variant - used in mission-critical industrial memory subsystems requiring fault resilience.
For engineers reviewing the CY7C1069G-10ZSXIT datasheet, CY7C1069G-10ZSXIT pinout, CY7C1069G-10ZSXIT application, or CY7C1069G-10ZSXIT equivalent, key selection criteria include ECC-enabled reliability, multi-voltage support, TSOP II package compatibility, CE1/CE2 decoding logic, and 10 ns tAA timing at 5 V.
Technical Context
The CY7C1069G-10ZSXIT implements a dual-chip-enable architecture where CE1 LOW and CE2 HIGH activate the device; WE LOW enables write, OE LOW enables read. Its internal ECC encoder/decoder performs real-time single-bit correction on every read, with ERR assertion indicating corrected errors - though automatic write-back is not supported.
It uses a 21-bit address bus (A0–A20) to access 2M words, eight bidirectional I/O lines (I/O0–I/O7), and supports three distinct VCC operating windows. Input/output pins enter high-impedance state during deselection (CE1 HIGH or CE2 LOW), write (WE LOW), or output disable (OE HIGH).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Mbit (2,097,152 × 8 bits) - provides byte-wide storage for embedded controllers needing deterministic latency and no refresh overhead. |
| Access Time (tAA) | 10 ns at VCC = 4.5–5.5 V - ensures sub-100 MHz synchronous interface timing without wait states in legacy microprocessor buses. |
| ECC Function | Single-bit error detection and correction per 8-bit word - mitigates soft errors in industrial environments without software intervention. |
| Supply Voltage Ranges | 1.65–2.2 V, 2.2–3.6 V, and 4.5–5.5 V - enables drop-in replacement across legacy 5 V, modern 3.3 V, and ultra-low-power 1.8 V systems. |
| Active Current (ICC) | 90 mA typical at 100 MHz - balances performance and power in always-on industrial control modules. |
| Standby Current (ISB2) | 20 mA typical - maintains low quiescent draw during sleep modes while preserving full memory content at 1.0 V. |
| Data Retention Voltage | 1.0 V minimum - allows extended battery-backed operation during brownout or backup power scenarios. |
Pinout & Package
The CY7C1069G-10ZSXIT is packaged in a Pb-free 54-pin TSOP II (Thin Small Outline Package, Type II) with center power/ground pinout configuration. Pin functions are validated per Cypress Document 001-81539 Rev. *J, Figures 1 and 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | 21-bit address bus selecting one of 2M locations; A20 enables full 16-Mbit addressing. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface; high-impedance when CE1 HIGH, CE2 LOW, OE HIGH, or WE LOW. |
| CE1, CE2 | Dual Chip Enable Inputs | Active-LOW CE1 and active-HIGH CE2 form logical AND enable - improves noise immunity vs. single CE. |
| WE | Write Enable Input | Active-LOW signal controlling write cycle initiation; latches data on rising edge of WE in some timing modes. |
| OE | Output Enable Input | Active-LOW signal enabling output drivers; independent of WE to support read-modify-write sequences. |
| VCC, VSS | Power and Ground | Multiple VCC/VSS pins distributed across package center for low-impedance supply routing and reduced switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC | Hardware-level single-bit error correction per 8-bit word - eliminates need for external ECC logic or software overhead. |
| Dual Chip Enable (CE1/CE2) | Asymmetric enable logic (CE1 LOW + CE2 HIGH) reduces false enable risk in noisy industrial backplanes. |
| Multi-Voltage Operation | Three discrete VCC ranges allow reuse across 5 V legacy, 3.3 V mid-range, and 1.8 V low-power designs without redesign. |
| 1.0-V Data Retention | Preserves memory contents at 1.0 V - enables seamless transition to battery backup during AC loss in PLCs and HMIs. |
| TTL-Compatible I/O | Meets standard TTL voltage thresholds (VIH ≥ 2.0 V, VOL ≤ 0.4 V at 5 V) - ensures interoperability with legacy microcontrollers and FPGAs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECC SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS61WV20488BLL-10MLI | No integrated ECC; requires external error handling; 10 ns access at 3.3 V only; 48-pin TSOP. | Lacks hardware ECC - suitable for cost-sensitive, non-safety-critical applications where software ECC is acceptable. | Select if ECC is managed externally and 5 V operation is unnecessary. |
| Micron MT45W8MW16BGX-10IT | DDR2 SDRAM with optional ECC mode; 10 ns tAA not applicable (CAS latency-based); requires refresh and initialization. | Dynamic memory architecture introduces timing complexity and power variability - unsuitable for deterministic real-time buffers. | Choose only when system already uses DDR2 controller and can tolerate refresh overhead and latency jitter. |
Compared with IS61WV20488BLL-10MLI and MT45W8MW16BGX-10IT, the CY7C1069G-10ZSXIT uniquely delivers hardware ECC, true static operation, multi-voltage support, and deterministic 10 ns access - making it irreplaceable in safety-certified, battery-backed, or legacy-bus-coupled systems.

FAQ
Does CY7C1069G-10ZSXIT support automatic error correction write-back?
No. The device detects and corrects single-bit errors during read operations and asserts the ERR pin, but does not perform automatic write-back of corrected data to the memory array. Host firmware must initiate any corrective write if persistent correction is required.
What is the function of the dual chip enable (CE1 and CE2) inputs?
CE1 and CE2 implement an AND-gated chip select: the device is enabled only when CE1 is LOW and CE2 is HIGH. This asymmetric logic improves noise margin over single CE designs and prevents spurious activation in electrically noisy industrial environments.
Can CY7C1069G-10ZSXIT operate at 2.5 V?
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. Operation at 2.5 V falls outside all specified ranges and is not characterized or guaranteed for timing, current, or reliability.
Is the ERR pin present on CY7C1069G-10ZSXIT?
No. The ERR pin is exclusive to the CY7C1069GE variant. CY7C1069G-10ZSXIT is the base version without error indication output; ECC correction occurs internally but is not signaled externally.
