Product details
Overview
CY7C1061GE18-15ZXI 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 ERR output pin. It operates across three voltage ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V), delivers 15 ns access time, and supports industrial temperature (–40 °C to +85 °C) in a 48-pin TSOP I package - used in mission-critical memory subsystems requiring data integrity.
For engineers reviewing the CY7C1061GE18-15ZXI datasheet, CY7C1061GE18-15ZXI pinout, CY7C1061GE18-15ZXI application, or CY7C1061GE18-15ZXI equivalent, key selection criteria include ECC-enabled read reliability, dual-voltage support, ERR signal timing behavior, byte-enable write control (BHE/ BLE), and industrial-grade standby current (ISB2 = 20 mA typical).
Technical Context
The CY7C1061GE18-15ZXI implements on-die Hamming-code ECC logic that detects and corrects single-bit errors during read cycles, asserting the ERR pin high upon correction. It does not perform automatic write-back, requiring external logic for error logging or recovery coordination.
It supports both single CE (CE pin only) and dual CE (CE1/CE2) configurations; this variant uses single CE and includes the ERR output. Addressing uses A0–A19 (20-bit), enabling full 1M-word access, with I/O0–I/O15 bidirectional data lines and dedicated byte enables (BHE for upper byte, BLE for lower byte).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit words) - provides 2 MB of byte-addressable storage with ECC protection per word. |
| Access Time (tAA) | 15 ns at VCC = 1.8 V - guarantees deterministic read latency for real-time control and boot memory applications. |
| VCC Operating Ranges | 1.65–2.2 V, 2.2–3.6 V, and 4.5–5.5 V - enables drop-in compatibility 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 - defines power budget for high-throughput memory interfaces in industrial controllers. |
| Standby Current (ISB2) | 20 mA typical - ensures low quiescent draw during system sleep modes without disabling ECC logic. |
| ECC Function | Single-bit error detection and correction per 16-bit word - reduces uncorrectable error rate to <0.1 FIT/Mb, critical for safety-aware firmware storage. |
| ERR Output | Open-drain active-high signal asserted during corrected read - enables hardware-triggered error logging or fault flagging without CPU polling. |
Pinout & Package
Package: 48-pin TSOP I (12 × 18.4 × 1 mm), RoHS-compliant, industrial-grade (–40 °C to +85 °C).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| CE | Chip Enable (active-low) | Enables memory access; device enters high-Z state when deasserted, reducing bus contention and dynamic power. |
| OE | Output Enable (active-low) | Controls tri-state output drivers; allows shared data bus operation with other peripherals without external buffers. |
| WE | Write Enable (active-low) | Initiates write cycle; combined with address and BHE/ BLE determines which bytes are updated in the target location. |
| BHE / BLE | Byte High / Low Enable | Enable independent 8-bit writes to upper (I/O8–I/O15) or lower (I/O0–I/O7) byte lanes - essential for mixed-endian or partial-word updates. |
| ERR | Error indication output | Asserted high during successful single-bit correction; requires external pull-up; no internal driver - avoids false triggers in floating conditions. |
| A0–A19 | Address inputs | 20-bit address bus supporting full 1M-word linear addressing; A19 placement fixed at pin 25 in ZXI package per datasheet Figure 7. |
| I/O0–I/O15 | Bidirectional data bus | 16-bit parallel interface with TTL-compatible thresholds - interoperable with legacy microcontrollers and FPGAs without level shifters. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC logic | On-die Hamming-code circuitry corrects single-bit errors in real time without software overhead or external syndrome calculation. |
| Multi-voltage operation | Three discrete VCC ranges allow reuse across 5 V legacy systems, 3.3 V mid-range designs, and 1.8 V low-power applications - no redesign needed for voltage migration. |
| ERR output signaling | Dedicated open-drain pin reports correction events synchronously with read data - enables deterministic fault response in safety-critical boot loaders. |
| Industrial temperature range | Rated –40 °C to +85 °C with guaranteed timing and ECC functionality - suitable for factory automation, transportation, and outdoor edge nodes. |
| Low ISB2 standby current | 20 mA typical at max VCC and f = 0 - maintains data retention (1.0 V minimum) while minimizing energy use during idle periods. |
Applications
| Industrial PLC Memory Buffer | Medical Imaging Frame Store |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECC SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS7C31026B-15TIN | No integrated ECC; requires external syndrome generator and correction logic; 15 ns access, 3.3 V only. | Lacks hardware-level error reporting; increases FPGA resource usage and firmware complexity for error handling. | Select only if cost sensitivity outweighs reliability requirements and external ECC logic is already implemented. |
| IS61WV102416BLL-15TLI | Includes ECC but no ERR output pin; correction status visible only via status register read; 15 ns, 3.3 V only. | Requires polling or interrupt-driven register reads to detect corrections - adds latency and CPU load versus direct ERR signaling. | Prefer when system architecture already uses register-based status monitoring and lacks GPIO for dedicated ERR handling. |
Compared with AS7C31026B-15TIN and IS61WV102416BLL-15TLI, CY7C1061GE18-15ZXI uniquely delivers autonomous, pin-level error notification without software intervention or additional logic - critical for hard real-time and safety-certified systems where latency and determinism are non-negotiable.

FAQ
Does CY7C1061GE18-15ZXI 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. External logic or firmware must handle write-back if persistent correction is required. This design minimizes latency and avoids unintended writes during transient faults.
What is the function of the NC pins in the 48-pin TSOP I package?
NC (No Connect) pins - such as pin 26 and pin 47 in the ZXI package - are physically present but not bonded to the silicon die. They serve mechanical or thermal roles in the package and must remain unconnected in PCB layout. Routing traces or applying voltage to NC pins may cause electrical interference or mechanical stress.
Can CY7C1061GE18-15ZXI operate reliably at 1.65 V with 15 ns timing?
Yes. The 15 ns access time is fully specified and tested over the entire 1.65–2.2 V range, including at the 1.65 V minimum. Datasheet AC switching characteristics (page 10) confirm tAA ≤ 15 ns under VCC = 1.65 V, TA = –40 °C to +85 °C, and load conditions defined in Figure 8.
How is the ERR pin electrically configured, and what pull-up value is recommended?
The ERR pin is an open-drain output requiring an external pull-up resistor. Infineon recommends a 4.7 kΩ resistor to VCC (same rail as memory VCC) for reliable rise time and noise immunity. Leaving ERR floating is acceptable per datasheet Note 8, but a pull-up ensures defined logic levels during power-up and error-free system reset sequencing.
