Product details

Overview

S25FL128LAGBHV030 from Infineon is a 128-Mbit serial NOR flash memory with 3.0 V supply voltage, 133 MHz Quad SPI interface, uniform 256-byte programming and 4-KB/32-KB/64-KB erase granularity, supporting XIP operation in standard and fast read modes. It is used in industrial PLC firmware storage and boot code retention.

For engineers reviewing the S25FL128LAGBHV030 datasheet, S25FL128LAGBHV030 pinout, S25FL128LAGBHV030 application, or S25FL128LAGBHV030 equivalent, key selection criteria include erase block size flexibility, Quad SPI timing compliance, write endurance (100K cycles), data retention (20 years), and industrial temperature range support.

Technical Context

This device implements a SPI-compatible command set with dual/quad I/O support, including volatile status register writes and configurable latency for read operations. It features a 256-byte page programming buffer and supports both sector and bulk erase commands with hardware reset recovery.

The memory array is organized as 256 Kbytes × 64 bits, with dedicated security registers for OTP lock bits and 128-bit unique ID. Write protection is enforced via WP# pin control and software status register bits SRWD and BP[2:0].

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 voltage, but uses WSON-8 (6×5 mm) package instead of SOIC-8; identical timing and command set	Preferred for space-constrained PCB layouts where footprint reduction is critical	Select when board area is limited and thermal profile permits WSON package
MX25L12833FZNI-10G	128 Mbit, 3.3 V, 104 MHz Quad SPI, but only 10-year data retention and −40°C to +85°C rating	Suitable for commercial-grade consumer electronics, not extended-temp industrial use	Choose only for cost-sensitive, non-industrial applications with relaxed reliability requirements

Compared with S25FL128SAGMFI000, this SOIC-8 variant offers easier hand-soldering and legacy board compatibility; versus MX25L12833FZNI-10G, it delivers superior temperature range and data retention for mission-critical deployments.

FAQ

What is the maximum clock frequency supported in Quad SPI mode?

The S25FL128LAGBHV030 supports up to 133 MHz in Quad SPI read mode, delivering 66.5 MB/s effective throughput. This frequency is validated across the full industrial temperature range and requires proper PCB layout with matched trace lengths and controlled impedance.

Does this device support execute-in-place (XIP) operation?

Yes, the device supports XIP in both standard and fast read modes, allowing microcontrollers to execute code directly from flash without loading into RAM. XIP is enabled by default and requires no special configuration beyond setting appropriate latency in the configuration register.

How is hardware write protection implemented on this part?

Hardware write protection is implemented via the WP# pin: when held low, it disables all program and erase commands to protected sectors. Protection granularity is controlled by status register bits BP[2:0], and WP# must be high to modify those bits.

Is a unique identifier available for secure firmware binding?

Yes, the device includes a factory-programmed, read-only 128-bit unique ID stored in a dedicated security register. This ID is laser-trimmed during wafer test and cannot be altered, enabling cryptographic binding of firmware images to specific units.
