Infineon Technologies CY7C1061GE18-15ZXIT

Overview

CY7C1061GE18-15ZXIT 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, 15 ns access time, and ERR output pin for real-time error indication. It operates across 1.65–2.2 V supply, supports byte-wide writes via BHE/ BLE, and targets high-reliability industrial memory subsystems requiring data integrity in mission-critical control or instrumentation.

For engineers reviewing the CY7C1061GE18-15ZXIT datasheet, CY7C1061GE18-15ZXIT pinout, CY7C1061GE18-15ZXIT application, or CY7C1061GE18-15ZXIT equivalent, this device delivers deterministic ECC correction without write-back, low ISB2 standby current (20 mA typical), and dual-chip-enable compatibility - key selection criteria for fault-tolerant SRAM replacement in avionics, medical imaging buffers, and programmable logic controllers.

Technical Context

The CY7C1061GE18-15ZXIT implements on-die Hamming-code ECC logic that detects and corrects single-bit errors during read cycles, asserting the ERR pin high upon correction. Its architecture separates address decoding, ECC syndrome generation, and data path correction into synchronous, non-intrusive stages - ensuring no latency penalty beyond tAA = 15 ns.

It supports three voltage ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V), but the -15ZXIT suffix confirms 1.65–2.2 V operation at 15 ns speed grade. The TSOP I package (48-pin) uses single CE with dedicated ERR output, distinguishing it from dual-CE variants and enabling simplified interface timing in microcontroller-based systems.

FAQ

Does CY7C1061GE18-15ZXIT support automatic error write-back after correction?

No. The device performs single-bit error correction during read cycles but does not automatically write the corrected data back to the memory array. Correction is transient and applies only to the output data bus; the original corrupted bit remains unmodified in the array until overwritten by a subsequent write operation. This behavior is explicitly documented in Note 1 of the datasheet.

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 cycle. If unused, it must be left floating per datasheet Note 6; if monitored, it requires an external pull-up resistor (typically 4.7 kΩ to VCC) to generate a valid logic HIGH signal for interrupt or status capture.

Can CY7C1061GE18-15ZXIT operate at 3.3 V?

No. The -15ZXIT suffix specifies the 1.65–2.2 V voltage range and 48-pin TSOP I package. While other variants (e.g., CY7C1061GE30) support 2.2–3.6 V, this specific part is characterized and guaranteed only for 1.65–2.2 V operation - applying 3.3 V exceeds absolute maximum ratings and risks permanent damage.

How does the CY7C1061GE18-15ZXIT differ from the CY7C1061G18 variant?

The CY7C1061GE18 includes the ERR output pin for hardware error indication, whereas the CY7C1061G18 omits this pin and provides no error status signal. Both share identical memory density, ECC functionality, timing, and voltage specs - the GE suffix denotes the presence of the ERR feature, confirmed by pinout Figures 7 and 4 in the datasheet.
