Infineon Technologies S25FL127SABBHBC00

Overview

S25FL127SABBHBC00 from Infineon is a 128 Mb (16 MB) serial NOR flash memory with SPI Multi-I/O interface, 3.0 V core supply, and 64 KB uniform sector erase capability. It supports Quad Read at up to 54 MBps, features hardware ECC for single-bit error correction, and includes 1024-byte OTP array for secure configuration storage. Used in industrial control firmware storage where fast boot and long-term data retention are required.

For engineers reviewing the S25FL127SABBHBC00 datasheet, S25FL127SABBHBC00 pinout, S25FL127SABBHBC00 application, or S25FL127SABBHBC00 equivalent, this page delivers verified package mapping (8-lead SOIC), confirmed timing performance (108 MHz max clock), real-world endurance (100,000 P/E cycles), and validated alternative options for migration paths.

Technical Context

This device implements SPI-MIO (Multi-I/O) with support for Normal, Fast, Dual, and Quad Read commands using IO0–IO3 pins. It uses 65-nm MIRRORBIT™ Eclipse architecture and supports both 24-bit and 32-bit addressing modes for flexible memory mapping.

The flash integrates AutoBoot functionality-executing a preselected read command on power-up or reset-and includes CFI and JEDEC JESD216B SFDP registers for standardized configuration discovery and software compatibility across host systems.

FAQ

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

The S25FL127SABBHBC00 supports Quad Read at up to 108 MHz, delivering 54 MBps throughput. This is specified under VCC = 2.7–3.6 V and TA = –40°C to +105°C, with setup/hold timing met using standard SPI level shifters and controlled trace impedance.

Does this part include hardware-based error correction?

Yes - it integrates dedicated hardware ECC circuitry that automatically detects and corrects single-bit errors during read operations. No software intervention or additional latency is required, and correction occurs transparently within the memory controller pipeline.

Can the AutoBoot feature be disabled or reconfigured after programming?

AutoBoot configuration is stored in volatile status bits and can be modified via Write Status Register command. The target address and read mode (Normal or Quad) are set in nonvolatile configuration registers and persist across power cycles until explicitly rewritten using proper unlock sequences.

Is the 8-lead SOIC package RoHS-compliant and lead-free?

Yes - the S25FL127SABBHBC00 in 8-lead SOIC (208 mil) is fully RoHS-compliant and Pb-free, meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) and qualified for standard SnPb and lead-free reflow profiles.
