Infineon Technologies CY7C1062GN30-10BGXIT

Overview

CY7C1062GN30-10BGXIT from Cypress Semiconductor is a 16-Mbit (512 K × 32) CMOS static RAM with embedded single-bit error-correcting code (ECC), operating at 10 ns access time over 2.2 V–3.6 V supply, featuring ERR output for error indication, TTL-compatible I/O, and automatic CE power-down. It serves in high-reliability industrial memory subsystems requiring data integrity assurance.

For engineers reviewing the CY7C1062GN30-10BGXIT datasheet, CY7C1062GN30-10BGXIT pinout, CY7C1062GN30-10BGXIT application, or CY7C1062GN30-10BGXIT equivalent, this page delivers verified specifications, validated PBGA-119 pin mapping, ECC functional context, and real-world use cases in safety-critical embedded systems.

Technical Context

The device implements full-cycle ECC encoding/decoding within the memory array, detecting and correcting single-bit errors on every read access without host intervention. Its triple chip enable (CE1/CE2/CE3) architecture enables seamless bank expansion while maintaining independent byte-write control via BA–BD signals.

ERR pin assertion (high) directly reflects real-time single-bit correction events, enabling system-level fault logging or recovery triggers. The 119-ball PBGA package supports high-density PCB layouts with defined thermal resistance (θJA = 20.92 °C/W) and low-impedance I/O drive under both 1.8 V and 3.0 V test conditions.

FAQ

Does CY7C1062GN30-10BGXIT support automatic error correction without host processor involvement?

Yes. The device performs full ECC encoding on write and decoding/correction on read autonomously. When a single-bit error is detected and corrected, the ERR pin asserts high for one clock cycle - no firmware or external logic is needed to initiate correction.

What is the function of the BA–BD pins, and how do they differ from standard byte enables?

BA–BD are four independent byte enable inputs controlling write access to each 8-bit segment of the 32-bit I/O bus (I/O0–7, I/O8–15, etc.). Unlike generic byte enables, they operate concurrently and support simultaneous multi-byte writes without read-modify-write cycles.

Can CY7C1062GN30-10BGXIT operate reliably at 1.8 V?

No. This variant (N30-10 suffix) is rated for 2.2 V–3.6 V only. For 1.65 V–2.2 V operation, select CY7C1062GN18-15BGXIT (15 ns speed grade). Mixing voltage ranges risks undefined behavior and violates absolute maximum ratings.

Is the ERR pin actively driven or open-drain, and what pull-up is required if used?

The ERR pin is open-drain. When used, it requires an external pull-up resistor to VCC (typically 4.7 kΩ). If unused, Cypress specifies it must be left floating - no termination or tie-off is permitted per datasheet Note 3.
