Product details
Overview
S25FL128LAGBHV023 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0–3.6 V supply voltage, 100 MHz clock frequency, and 133 MHz DDR read speed, used in boot code storage for industrial microcontrollers.
For engineers reviewing the S25FL128LAGBHV023 datasheet, S25FL128LAGBHV023 pinout, S25FL128LAGBHV023 application, or S25FL128LAGBHV023 equivalent, key selection criteria include sector protection granularity, erase suspend/resume capability, and hardware reset support for fail-safe firmware recovery.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode, supporting both single- and dual-data-rate (SDR/DDR) read operations. It features a 4-Kbyte uniform sector architecture with individual sector lock bits and supports JEDEC JESD216B compliant SFDP for automatic configuration detection.
The memory includes an internal write state machine enabling automatic page programming and block erasure without external timing control. It supports volatile and non-volatile status register writes for configuration persistence across power cycles.
Key Specifications

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 |
|---|---|---|---|
| S25FL128SAGMFI000 | Same density and package but uses 1.8 V core supply; requires dual-voltage IO buffer | Targeted at ultra-low-power portable systems, not industrial 3.3 V rails | Select only if host MCU supports 1.8 V I/O and power budget mandates lower active current |
| MX25L12833FZNI-10G | 104 MHz max SDR read speed; no DDR mode; lacks secure silicon sector | Cost-sensitive consumer applications where security and high-speed boot are secondary | Choose when DDR performance and cryptographic key storage are not required |
Compared with S25FL128SAGMFI000, this part avoids level-shifting complexity in 3.3 V systems; versus MX25L12833FZNI-10G, it delivers faster boot and hardware-enforced security-justifying premium in industrial firmware storage.

FAQ
What is the maximum clock frequency supported in DDR mode?
The S25FL128LAGBHV023 supports up to 133 MHz in DDR mode, delivering 66.5 MB/s effective read bandwidth. This is specified under VCC = 3.0–3.6 V and TA = −40°C to +105°C, with setup/hold timing validated per JEDEC JESD252A.
Does this part support hardware reset functionality?
Yes, it includes an active-low RESET# pin that asynchronously resets the internal state machine, clears the busy flag, and returns the device to standby mode-enabling reliable recovery after brown-out or watchdog timeout events.
Can the secure silicon sector be reprogrammed after initial write?
No-the secure silicon sector is one-time-programmable (OTP). Once written, its 256 bytes cannot be erased or modified, ensuring permanent storage of cryptographic keys or device-unique identifiers for security-critical applications.
Is sector protection implemented via software or hardware?
Sector protection is implemented through both hardware and software methods: WP# pin enables physical write protection of top/bottom sectors, while status register bits allow software-controlled locking of any 4-Kbyte sector individually.
