Infineon Technologies CY62147G30-45ZSXAT

Overview

CY62147G30-45ZSXAT from Cypress Semiconductor is a 4-Mbit (256K × 16) automotive-grade MoBL® SRAM with embedded single-bit error-correcting code (ECC), 45 ns access time, 2.2–3.6 V supply range, and -40 °C to +85 °C operation. It supports byte-level write control via BHE/ BLE, TTL-compatible I/Os, and ultra-low standby current (3.5 µA typical) for safety-critical memory buffering in ADAS controllers.

For engineers reviewing the CY62147G30-45ZSXAT datasheet, CY62147G30-45ZSXAT pinout, CY62147G30-45ZSXAT application, or CY62147G30-45ZSXAT equivalent, key selection criteria include ECC-enabled data integrity, automotive-A temperature compliance, VFBGA-48 packaging, byte power-down capability, and dual-chip-enable compatibility with legacy memory interfaces.

Technical Context

This SRAM implements a synchronous CMOS architecture with dedicated ECC encoder/decoder logic integrated into the memory array path, correcting single-bit errors on read without automatic write-back. The device uses separate row/column decoders and sense amplifiers optimized for low-voltage operation across its full 2.2–3.6 V VCC range.

It supports two chip enable configurations: single CE (CY62147G) and dual CE1/CE2 (CY621472G); this part uses the single CE variant. Byte enable logic (BHE/BLE) gates write operations to upper/lower 8-bit lanes independently, enabling efficient 8-bit peripheral interfacing while maintaining full 16-bit bandwidth when needed.

FAQ

Does CY62147G30-45ZSXAT support automatic error correction during read operations?

Yes - the device performs real-time single-bit error correction on every read access using on-die ECC logic. Detected errors are corrected before data reaches the I/O pins, and no external intervention or write-back is required. However, it does not support automatic write-back on error detection per datasheet Note 1.

What is the maximum junction temperature for continuous operation in automotive under-hood environments?

The device is rated for ambient temperatures from –40 °C to +85 °C (Automotive-A grade). With θJA = 31.17 °C/W in VFBGA package and typical power dissipation of 15 mA at 45 ns, junction temperature remains within safe limits (<125 °C) even at 85 °C ambient under worst-case load, assuming standard four-layer PCB layout.

Can CY62147G30-45ZSXAT be used with a 2.5 V supply rail?

Yes - the specified VCC range is 2.2 V to 3.6 V, fully covering 2.5 V operation. All DC and AC parameters, including 45 ns access time and 3.5 µA standby current, are guaranteed across this range per the datasheet's Automotive-A characterization.

Is the 48-ball VFBGA package lead-free and RoHS-compliant?

Yes - the "Z" in the part number suffix denotes Pb-free (lead-free) construction, and the device complies with RoHS Directive 2011/65/EU. The package uses matte tin surface finish on solder balls and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements.
