Infineon Technologies S25FL127SABBHIC03

Overview

S25FL127SABBHIC03 from Infineon is a 128 Mb (16 MB) SPI Multi-I/O serial NOR flash memory IC with 3.0 V core, 64 KB uniform sector erase, Quad Read up to 54 MBps, and integrated hardware ECC for single-bit error correction. It supports AutoBoot, CFI, SFDP, and OTP security in an 8-contact WSON 6 × 5 mm package, deployed in industrial embedded boot code storage.

For engineers reviewing the S25FL127SABBHIC03 datasheet, S25FL127SABBHIC03 pinout, S25FL127SABBHIC03 application, or S25FL127SABBHIC03 equivalent, key selection criteria include Quad I/O read bandwidth, 20-year data retention, AEC-Q100 Grade 2 qualification, hybrid/uniform erase options, and OTP-based secure silicon region configuration.

Technical Context

This device implements SPI-MIO (Multi-Input/Output) interface supporting clock modes 0 and 3, with configurable 24-/32-bit addressing and command sets compatible with S25FL-A/K/P families. It uses 65-nm MIRRORBIT™ Eclipse architecture for high endurance and low-power operation.

The internal ECC engine performs automatic single-bit error correction during read operations, while the AutoBoot feature enables automatic execution of Normal or Quad Read at power-up from a preselected address-critical for deterministic firmware initialization in safety-aware systems.

FAQ

What is the maximum clock frequency supported for Quad Read operations?

The S25FL127SABBHIC03 supports Quad Read at up to 108 MHz, delivering 54 MBps effective throughput. This rate is guaranteed across the full industrial plus temperature range (–40°C to +105°C) and requires proper PCB layout with matched trace lengths and controlled impedance to maintain signal integrity.

Does this device require external hardware ECC circuitry?

No. The S25FL127SABBHIC03 integrates a dedicated hardware ECC engine that automatically detects and corrects single-bit errors during read operations. No external circuitry or host CPU intervention is needed, and correction occurs transparently within the memory's internal data path.

Can the AutoBoot address be modified after initial programming?

Yes. The AutoBoot start address is stored in a dedicated configuration register (CR2[7:0]) and can be updated via standard Write Enable + Write Status Register commands. Changes persist across power cycles and do not require OTP programming-enabling field-upgradable boot configurations.

Is the 8-contact WSON package lead-free and RoHS compliant?

Yes. The S25FL127SABBHIC03 in the 8-contact WSON 6 × 5 mm package is fully RoHS-compliant and Pb-free, with matte tin (Sn) termination finish. It meets JEDEC J-STD-020D moisture sensitivity level 3 (MSL3) and is qualified for reflow soldering per IPC/JEDEC J-STD-020.
