Product details
Overview
S25FL128LAGBHI023 from Infineon is a 128-Mbit serial NOR flash memory with Quad SPI interface, 3.0–3.6 V supply, 100 MHz clock frequency, and 133 MHz equivalent read speed in DDR mode. It operates across –40°C to +85°C industrial temperature range and supports XIP (execute-in-place) for microcontroller boot code storage in embedded systems.
For engineers reviewing the S25FL128LAGBHI023 datasheet, S25FL128LAGBHI023 pinout, S25FL128LAGBHI023 application, or S25FL128LAGBHI023 equivalent, key selection criteria include Quad SPI timing compliance, sector protection granularity, erase suspend/resume capability, and industrial-grade reliability for firmware storage in edge nodes and programmable logic controllers.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended Quad I/O (QPI) mode for higher throughput. It uses uniform 4-KB sectors and 256-KB blocks, with configurable write protection via status register bits and hardware WP# pin.
Internal architecture includes a 256-byte page buffer for fast programming, 100K program/erase cycle endurance, and data retention of 20 years at 85°C. The device supports both volatile and non-volatile configuration registers for flexible command set control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL128SAGMFI001 | Same density and package but with 1.8 V core voltage option and enhanced deep power-down mode | Targeted at battery-powered IoT sensors requiring ultra-low standby current (<1 µA) | Select if system uses dual-voltage rails and demands sub-µA sleep current |
| MX25L12833FZNI-10G | 128 Mbit, 104 MHz max clock, no DDR mode, lacks OTP security register and erase suspend | Suitable for cost-sensitive consumer electronics where security and real-time interrupt handling are not required | Choose only when XIP performance and firmware security are secondary to BOM cost reduction |
Compared with S25FL128SAGMFI001, this part offers superior industrial temperature support and simpler 3.3 V-only biasing; versus MX25L12833FZNI-10G, it delivers faster boot, secure firmware updates, and deterministic erase behavior essential for safety-critical firmware storage.

FAQ
Is S25FL128LAGBHI023 pin-compatible with earlier S25FL128Lxxx variants?
Yes, it shares identical 8-pin SOIC (208-mil) footprint and pin assignment with all S25FL128L-series parts, including S25FL128LAGNFI000 and S25FL128LAGMFV000. No PCB redesign is needed for drop-in replacement, provided voltage and timing margins remain within spec.
Does this device support Dual Transfer Rate (DTR) mode?
No, S25FL128LAGBHI023 supports only Single Transfer Rate (STR) in Quad SPI mode, with maximum clock frequency of 133 MHz. DTR mode is not implemented; DDR functionality refers to double-data-rate sampling on the rising and falling edges of STR clocks-not true DTR command encoding.
What is the minimum erase block size supported?
The smallest erasable unit is a 4-KB uniform sector. The device does not support 256-byte or 512-byte page erase; all erase operations target either one 4-KB sector or larger blocks (32 KB or 64 KB), with no partial-sector erase capability.
Can the WP# pin be used for permanent write protection of specific sectors?
WP# provides hardware-level protection only for the top/bottom 4-KB sectors (addresses 0x000000–0x000FFF and 0xFF0000–0xFFFFF). Full sector protection requires software configuration of the status register's SEC and TB/BP bits-WP# alone cannot lock arbitrary sectors.
