Product details
Overview
CY7C1061GE-10ZXIT from Infineon Technologies (formerly Cypress) is a 16-Mbit (1M × 16-bit) CMOS static RAM with embedded single-bit error-correcting code (ECC), TTL-compatible I/O, and an active-high ERR output pin for real-time error indication. It operates across three voltage ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V), delivers 10 ns access time at 5 V, and supports industrial temperature range (–40 °C to +85 °C). Used in mission-critical embedded controllers requiring data integrity.
For engineers reviewing the CY7C1061GE-10ZXIT datasheet, CY7C1061GE-10ZXIT pinout, CY7C1061GE-10ZXIT application, or CY7C1061GE-10ZXIT equivalent, key selection criteria include ECC-enabled reliability, dual-voltage operation, TSOP I package compatibility, and ERR signal integration for fault-aware memory subsystems in avionics, medical diagnostics, and industrial PLCs.
Technical Context
This SRAM implements on-die Hamming-code ECC logic that detects and corrects single-bit errors during read cycles without external circuitry. The ERR pin asserts high only when correction occurs, enabling system-level error logging without interrupt overhead.
It supports both single CE (CE pin only) and dual CE (CE1/CE2) configurations, with byte-enable control (BHE/ BLE) for 8-bit sub-word accesses. Address space spans A0–A19 (1 M words), and all I/Os enter high-Z state when deselected or during standby modes ISB1/ISB2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit words) - provides full 2 MB of addressable data space with ECC protection per word. |
| Access Time (tAA) | 10 ns at VCC = 4.5–5.5 V - enables direct interfacing with 100 MHz bus systems without wait states. |
| ECC Function | Embedded Hamming-code single-bit error correction with ERR output assertion - eliminates need for external ECC logic or software correction routines. |
| Supply Voltage Ranges | 1.65–2.2 V, 2.2–3.6 V, and 4.5–5.5 V - supports mixed-voltage system designs and legacy 5 V interfaces while enabling low-power operation. |
| Standby Current (ISB2) | 20 mA typical at VCC = 5 V - ensures low power consumption during idle periods in always-on industrial control modules. |
| Operating Temperature | –40 °C to +85 °C (Industrial grade) - qualified for deployment in harsh environments including factory automation and outdoor telecom equipment. |
| Data Retention | 1.0 V minimum retention voltage - allows memory contents to be preserved during brown-out conditions or controlled power-down sequences. |
Pinout & Package
Package: 48-pin TSOP I (12 × 18.4 × 1 mm), RoHS-compliant, surface-mount. Pin count and layout match JEDEC MO-147AC standard for drop-in replacement in existing PCB footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE | Chip Enable (active-low) | Enables memory access; device enters high-Z standby when CE is high - primary power gating control for low-ISB2 mode. |
| WE | Write Enable (active-low) | Controls write cycle initiation; latches data on rising edge of WE when CE and OE are asserted - defines timing boundary for data setup/hold. |
| OE | Output Enable (active-low) | Gates read data onto I/O pins; disables outputs (high-Z) when deasserted - isolates bus during concurrent write or address transitions. |
| BHE / BLE | Byte High/Low Enable (active-low) | Selects upper (I/O8–I/O15) or lower (I/O0–I/O7) byte for 8-bit writes - enables partial-word updates without read-modify-write overhead. |
| ERR | Error Indication Output (active-high) | Asserts high for one clock cycle upon successful single-bit correction - provides hardware-observable fault event for diagnostic firmware or watchdog escalation. |
| A0–A19 | Address Inputs | 20-bit address bus supporting 1 M-word addressing - A19 is MSB and maps to pin 25 in ZXI package; no address multiplexing required. |
| I/O0–I/O15 | Bi-directional Data Bus | 16-bit parallel interface with TTL-compatible thresholds - supports direct connection to microcontroller data buses without level-shifting. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC logic | On-die Hamming-code correction eliminates external ECC ICs and reduces BOM cost and board area by ~25 mm². |
| Multi-voltage support | Three independent VCC operating ranges allow use in hybrid systems (e.g., 1.8 V core + 5 V I/O) without external regulators or level shifters. |
| ERR output pin | Dedicated open-drain output signals correction events synchronously with read completion - enables deterministic error response without polling. |
| Low ISB2 current | 20 mA typical at 5 V enables >10-year battery-backed retention in safety-critical black-box recorders with minimal leakage impact. |
| TTL-compatible I/O | VIL ≤ 0.8 V and VOH ≥ VCC – 0.4 V ensure interoperability with legacy 5 V microcontrollers and FPGAs without interface logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECC SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS7C31026B-10TIN | No integrated ERR pin; ECC status requires polling register; 10 ns access at 3.3 V only. | Lacks hardware-error signaling - unsuitable for safety-critical systems requiring deterministic fault response. | Prefer when cost sensitivity outweighs need for real-time error notification and multi-voltage flexibility. |
| IS61WV102416BLL-10MLI | 10 ns access at 3.3 V; no ECC; 1.65–3.6 V supply; no ERR or BHE/ BLE support. | Requires external ECC engine or software correction - increases firmware complexity and latency. | Select only if ECC is implemented externally and strict 10 ns timing must be met at 3.3 V with minimal pin count. |
Compared with AS7C31026B-10TIN and IS61WV102416BLL-10MLI, CY7C1061GE-10ZXIT uniquely combines hardware-accelerated ECC, dedicated ERR signaling, triple-voltage operation, and industrial-grade reliability - making it the sole choice for applications where error detection latency, voltage flexibility, and functional safety traceability are mandatory.

FAQ
Does CY7C1061GE-10ZXIT require external circuitry to implement ECC?
No. The device integrates full Hamming-code ECC logic on-die. Single-bit errors are automatically detected and corrected during every read cycle, with the ERR pin asserting high to indicate correction occurred. No external syndrome generator, checker, or correction logic is needed - reducing design complexity and board space.
What is the function of the ERR pin, and how should it be used in system design?
The ERR pin is an active-high open-drain output that pulses high for one clock cycle whenever a single-bit error is corrected during a read access. It should be connected to a GPIO interrupt input or debounced latch to trigger diagnostic logging or fail-safe actions. If unused, it must be left floating per datasheet Note 6.
Can CY7C1061GE-10ZXIT operate at 2.5 V, and what performance trade-offs apply?
Yes - it supports the 2.2–3.6 V range. At 2.5 V, access time remains 10 ns (guaranteed per datasheet Rev. *T), but ICC increases to 90 mA typical at 100 MHz. Standby current ISB2 rises to 25 mA typical. No derating is required, and all timing parameters remain valid within this range.
Is the 48-pin TSOP I package (ZXI) pin-compatible with earlier CY7C1061G variants?
Yes. The ZXI package uses identical pinout and mechanical dimensions as prior CY7C1061G-10ZXI devices. The only difference is the addition of the ERR pin at position 1 (pin 1 = ERR instead of NC), maintaining backward compatibility for designs where ERR is unused or tied off.
