Infineon Technologies CY62147G18-55ZSXIT

Overview

CY62147G18-55ZSXIT from Infineon Technologies (formerly Cypress) is a 4-Mbit MoBL® SRAM with embedded single-bit error-correcting code (ECC), organized as 256K × 16-bit, operating at 55 ns access time across 1.65–2.2 V supply. It features TTL-compatible I/Os, ERR output for ECC event indication, and ultra-low standby current (3.5 µA typical). Used in industrial control modules requiring data integrity under radiation-prone or long-term operation conditions.

For engineers reviewing the CY62147G18-55ZSXIT datasheet, CY62147G18-55ZSXIT pinout, CY62147G18-55ZSXIT application, or CY62147G18-55ZSXIT equivalent, key selection criteria include ECC-enabled reliability, dual-chip-enable support, 48-ball VFBGA package compatibility, and 1.65–2.2 V low-voltage operation for power-constrained embedded systems.

Technical Context

This SRAM implements on-die ECC encoding/decoding logic that detects and corrects single-bit errors during read cycles without automatic write-back. The ERR pin asserts HIGH upon correction, enabling system-level fault logging. Memory array uses standard CMOS six-transistor cells with row/column decoding and sense amplifiers optimized for low-power, high-speed random access.

It supports byte-wide writes via independent BHE (I/O8–I/O15) and BLE (I/O0–I/O7) controls, and enters seamless standby when both byte enables are deasserted - independent of CE state. Dual CE architecture (CE1/CE2) allows hierarchical memory mapping in multi-bank systems.

FAQ

Does CY62147G18-55ZSXIT support automatic error correction write-back?

No. The device performs single-bit error correction during read cycles but does not automatically write the corrected data back to memory. System firmware must handle write-back if persistent correction is required. This design minimizes internal complexity and power consumption while retaining full ECC detection and correction capability on every read access.

What is the function of the ERR pin, and how should it be interfaced?

The ERR pin is an open-drain output that asserts HIGH when a single-bit error is detected and corrected during a read operation. It requires an external pull-up resistor (typically 4.7 kΩ to VCC) to establish a valid logic HIGH level. The signal remains asserted for one clock cycle after correction and can trigger interrupt-driven diagnostics in host controllers.

Can CY62147G18-55ZSXIT operate reliably at 1.65 V with full timing specifications?

Yes. The 55 ns access time, ECC functionality, and all DC/AC electrical parameters are fully specified and guaranteed over the entire 1.65 V to 2.2 V range. Typical ICC operating current is 15 mA and standby current is 3.5 µA at 1.8 V, confirming robust low-voltage operation without derating.

Is the 48-ball VFBGA package of CY62147G18-55ZSXIT compatible with standard reflow profiles?

Yes. The RoHS-compliant, lead-free 48-ball VFBGA adheres to IPC/JEDEC J-STD-020D moisture sensitivity level 3 (MSL3) and supports standard Pb-free reflow profiles with peak temperature up to 260 °C. Board layout must follow Infineon's recommended pad stack and stencil design guidelines to ensure solder joint reliability.
