Product details
Overview
CY7C1061G-10ZXI 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 10 ns access time. It operates across three voltage ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V), supports byte-wide writes via BHE/ BLE, and features an ERR output pin for real-time ECC event indication. Used in industrial control systems requiring data integrity under extended temperature (–40 °C to +85 °C).
For engineers reviewing the CY7C1061G-10ZXI datasheet, CY7C1061G-10ZXI pinout, CY7C1061G-10ZXI application, or CY7C1061G-10ZXI equivalent, this page delivers verified package mapping (48-pin TSOP I), ECC functional behavior, byte-enable timing constraints, and validated alternatives for memory subsystems where bit-flip resilience is critical.
Technical Context
The CY7C1061G-10ZXI implements on-die Hamming-code ECC logic that detects and corrects single-bit errors during read cycles without external circuitry. Its dual-mode chip enable (CE-only or CE1/CE2) and independent byte enables (BHE/BLE) allow flexible memory partitioning in 16-bit bus architectures.
It supports three distinct VCC operating windows with corresponding speed grades: 10 ns at 2.2–3.6 V and 4.5–5.5 V, and 15 ns at 1.65–2.2 V. The ERR pin asserts high only upon successful single-bit correction-no automatic write-back-and SER FIT rate is <0.1 FIT/Mb per AN88889.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 16 Mbit (1,048,576 words × 16 bits); provides full 16-bit parallel interface without external data multiplexing |
| Access time (tAA) | 10 ns max at VCC = 2.2–3.6 V or 4.5–5.5 V; defines minimum clock-to-data valid delay in synchronous read cycles |
| ECC capability | Single-bit error detection and correction per 16-bit word; no software overhead or external logic required |
| VCC range | 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 |
| Standby current (ISB2) | 20 mA typical at VCC = 5 V; reflects deep power-down state with CE inactive and CMOS inputs held |
| Operating current (ICC) | 90 mA typical at 100 MHz, VCC = 5 V; sets thermal and supply rail sizing requirements for sustained burst reads/writes |
| Data retention | 1.0 V minimum VCC; allows battery-backed operation down to 1 V while preserving contents |
Pinout & Package
Package: 48-pin TSOP I (12 × 18.4 × 1 mm), Industrial grade (–40 °C to +85 °C), Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE | Chip Enable (active LOW) | Primary device selection signal; places all I/Os in high-Z when HIGH; enables memory access only when asserted |
| WE | Write Enable (active LOW) | Controls write cycle initiation; latches address and data on falling edge; must be stable before tSA |
| OE | Output Enable (active LOW) | Enables read data onto I/O0–I/O15; does not affect internal memory state or ECC logic |
| BHE / BLE | Byte High/Low Enable | Selectively enables upper (I/O8–I/O15) or lower (I/O0–I/O7) byte writes; supports 8-bit peripheral interfacing |
| ERR | Error indication output | Open-drain HIGH pulse during read cycle when single-bit correction occurs; requires external pull-up |
| A0–A19 | Address inputs | 20-bit address bus supporting full 1M-word decoding; A19 placement varies by package variant (Ball G2 or H6 in VFBGA) |
| I/O0–I/O15 | Bi-directional data bus | 16-bit parallel interface; high-impedance when CE, OE, BHE, or BLE are deasserted |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC logic | Hardware-based Hamming-code correction eliminates need for external ECC controller or firmware intervention |
| TTL-compatible I/O | Supports direct interface to legacy microcontrollers and FPGAs without level-shifting circuitry |
| Multi-voltage operation | Three discrete VCC ranges allow reuse across 5 V, 3.3 V, and 1.8 V system designs without redesign |
| ERR output signaling | Dedicated open-drain pin reports correction events in real time, enabling system-level logging or fault recovery |
| Low-power standby mode | ISB2 = 20 mA typical enables energy-sensitive applications such as battery-backed industrial controllers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECC SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61WV102416BLL-10MLI | No dedicated ERR pin; ECC status requires polling register; 10 ns access at 3.3 V only | Lacks real-time error reporting; unsuitable for safety-critical systems requiring immediate fault notification | Choose when cost sensitivity outweighs need for hardware-interrupt-capable ECC signaling |
| AS6C1008-10TIN | 8-bit bus width; no ECC; 10 ns access at 5 V; no byte enables or ERR output | Requires external ECC engine and data-width adaptation; increases PCB area and firmware complexity | Choose only if existing design uses 8-bit bus and can accommodate external correction logic |
Compared with IS61WV102416BLL-10MLI and AS6C1008-10TIN, CY7C1061G-10ZXI uniquely delivers 16-bit ECC SRAM with real-time ERR signaling, multi-voltage support, and byte-select capability-enabling simpler, safer, and more scalable memory subsystems in industrial and transportation electronics.

FAQ
Does CY7C1061G-10ZXI support automatic error correction write-back?
No. The device performs single-bit error correction during read cycles and asserts the ERR pin, but it does not automatically rewrite the corrected data back to the memory array. Correction is transparent to the read data path only; any persistent fix requires external firmware intervention or system-level write-back logic.
What is the function of the ERR pin, and how should it be terminated?
The ERR pin is an open-drain output that goes HIGH during a read cycle when a single-bit error is detected and corrected. It must be externally pulled up to VCC with a 4.7 kΩ resistor. Leaving it floating or connecting it directly to VCC will prevent proper signaling; unused pins should be left unconnected per datasheet Note 8.
Can CY7C1061G-10ZXI 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 within the 2.2–3.6 V range and is fully supported, delivering 10 ns access time and 90 mA typical ICC at 100 MHz per datasheet Table on page 2.
How does byte enable (BHE/BLE) interact with ECC functionality?
BHE and BLE control which 8-bit half of the 16-bit word is written; ECC logic always processes the full 16-bit word. Writing only one byte triggers ECC calculation over the entire accessed word-including unchanged bits from the other byte-ensuring consistent error coverage regardless of write granularity.
