Product details
Overview
CY7C1061G-10ZSXIT from Infineon (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 for real-time ECC event indication. Used in industrial control modules requiring data integrity under radiation-prone or long-term operation conditions.
For engineers reviewing the CY7C1061G-10ZSXIT datasheet, CY7C1061G-10ZSXIT pinout, CY7C1061G-10ZSXIT application, or CY7C1061G-10ZSXIT equivalent, this page delivers verified package mapping (48-pin TSOP I), ECC functional behavior, byte-enable timing constraints, and validated alternatives for memory subsystem redesigns where bit-flip resilience is mandatory.
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-no automatic write-back is performed, preserving deterministic latency.
It supports dual chip enable (CE1/CE2) or single CE configurations, with BHE/BLE enabling independent upper/lower byte writes to I/O[15:8] and I/O[7:0]. Address range spans A0–A19 (1 M words), and data retention holds at 1.0 V, enabling low-power suspend modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit words) - defines maximum addressable storage space and bus width compatibility. |
| Access Time (tAA) | 10 ns at VCC = 4.5–5.5 V - guarantees minimum clock-to-data valid delay for synchronous system timing closure. |
| ECC Function | Single-bit error detection and correction per read cycle - eliminates need for external ECC logic in safety-critical buffers. |
| Operating Voltage | 1.65–2.2 V / 2.2–3.6 V / 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 max - sets baseline power budget for idle memory in always-on industrial controllers. |
| Data Retention Voltage | 1.0 V - allows retention during brown-out events without full power rail collapse. |
| Output Drive | TTL-compatible VOH/VOL - ensures interoperability with legacy microcontrollers and FPGAs lacking LVTTL or LVCMOS level-shifting. |
Pinout & Package
Package: 48-pin TSOP I (12 × 18.4 × 1 mm), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address inputs | 20-bit address bus supporting 1M-word addressing; A19 is MSB and determines top-half memory bank selection. |
| I/O0–I/O15 | Bidirectional data bus | 16-bit parallel interface; high-impedance when CE/OE/BLE/BHE inactive - prevents bus contention in shared-memory systems. |
| CE | Chip enable (active-low) | Single CE mode: device enabled only when CE = LOW; disables all outputs and reduces current to ISB2 level. |
| OE | Output enable (active-low) | Controls read data assertion onto I/O lines; must be LOW during valid address setup for read access. |
| WE | Write enable (active-low) | Triggers write cycle; latches data on I/O lines into addressed location when CE and OE are also asserted correctly. |
| BHE, BLE | Byte enable controls | BHE enables I/O[15:8], BLE enables I/O[7:0]; both required HIGH for full 16-bit writes, allowing partial-byte updates without read-modify-write. |
| ERR | Error indication output | Open-drain output asserted HIGH during single-bit correction event; requires external pull-up; no assertion on uncorrectable multi-bit errors. |
| VCC, VSS | Power supply pins | Dual VCC pins (pins 24 & 48) reduce IR drop; dedicated ground pins (pins 23 & 47) improve noise immunity in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC logic | On-die Hamming-code engine corrects single-bit errors per read without CPU intervention or additional latency overhead. |
| Multi-voltage support | Three discrete VCC ranges allow reuse across 5 V legacy, 3.3 V mid-range, and 1.8 V low-power designs without redesigning power delivery. |
| Byte-select write capability | BHE/BLE pins enable true 8-bit sub-word writes - critical for efficient firmware patching and configuration register updates. |
| ERR status signaling | Dedicated open-drain ERR pin provides immediate hardware-level notification of ECC correction, enabling logging or fault escalation. |
| 1.0 V data retention | Retains stored data down to 1.0 V supply - supports graceful degradation during power loss and extends battery-backed operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM with ECC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS7C31026B-10TIN | No integrated ECC; requires external logic or processor-based correction; 10 ns speed, same 1M×16 density and 48-pin TSOP I package. | Suitable only where ECC is implemented in firmware or external ASIC; lacks hardware ERR signal for real-time fault reporting. | Select when cost sensitivity outweighs ECC requirement and system architecture already handles error correction in software. |
| IS61WV102416BLL-10MLI | Includes ECC but uses different pinout (54-pin TSOP II); no ERR pin; supports 3.3 V only (2.2–3.6 V range), not 5 V or 1.8 V. | Requires PCB redesign due to package and pin mismatch; lacks voltage flexibility for mixed-rail legacy upgrades. | Choose only for new 3.3 V-only designs where board layout permits 54-pin footprint and ERR signaling is unnecessary. |
Compared with AS7C31026B-10TIN and IS61WV102416BLL-10MLI, CY7C1061G-10ZSXIT uniquely combines 5 V/3.3 V/1.8 V compatibility, hardware ERR signaling, and 48-pin TSOP I footprint - making it the sole option for retrofitting ECC into existing industrial boards without layer changes or voltage rail modifications.

FAQ
Does CY7C1061G-10ZSXIT perform automatic write-back after ECC correction?
No. The device corrects single-bit errors during read cycles but does not automatically rewrite the corrected data back to the memory array. This preserves deterministic read latency and avoids unintended write cycles that could interfere with concurrent operations. System-level software or external logic must handle persistent correction if required.
What is the function of the ERR pin, and how should it be terminated?
The ERR pin is an open-drain output that asserts HIGH only when a single-bit error is detected and corrected during a read access. If unused, it must be left floating per datasheet Note 6; adding an external pull-up resistor is required only when actively monitoring correction events for diagnostics or logging.
Can CY7C1061G-10ZSXIT operate at 2.5 V?
No. Its specified operating ranges are strictly 1.65–2.2 V, 2.2–3.6 V, and 4.5–5.5 V. A 2.5 V supply falls outside all defined ranges and may cause undefined behavior, increased leakage, or failure to meet tAA = 10 ns timing. Use only within the three validated bands.
Is the 48-pin TSOP I package of CY7C1061G-10ZSXIT compatible with standard JEDEC MO-118 specifications?
Yes. The 48-pin TSOP I package (12 × 18.4 × 1 mm) conforms to JEDEC MO-118, including lead pitch (0.5 mm), body dimensions, and solder profile recommendations. Pin 1 marking and orientation match industry-standard placement for automated assembly and rework compatibility.
