Product details
Overview
S25FL256LAGBHB033 from Infineon is a 256-Mbit serial NOR flash memory with Quad SPI interface, 133 MHz clock frequency, and 3.0 V supply voltage, used for code storage and execution in embedded microcontroller boot systems.
For engineers reviewing the S25FL256LAGBHB033 datasheet, S25FL256LAGBHB033 pinout, S25FL256LAGBHB033 application, or S25FL256LAGBHB033 equivalent, key selection criteria include read latency, sector erase granularity, write protection scheme, and industrial temperature range support.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with Quad I/O (QPI) mode enabling 4-bit data transfers per clock cycle. It supports both uniform and configurable sector architectures with 4-KB, 32-KB, and 64-KB erase blocks.
The memory includes hardware write protection via WP# pin and software-controlled block protection using status register bits. It operates across –40°C to +85°C and meets JEDEC JESD22-A110 reliability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 MB), sufficient for full firmware image storage in mid-tier MCUs |
| Interface | Quad SPI (QPI), enables 532 MB/s peak throughput at 133 MHz |
| Read Latency | 8 ns address-to-data delay in QPI mode, critical for zero-wait-state XIP execution |
| Erase Granularity | Supports 4-KB, 32-KB, and 64-KB sectors; allows fine-grained firmware update without full chip erase |
| Supply Voltage | 2.7–3.6 V, compatible with 3.3 V logic domains and brown-out tolerant operation |
| Operating Temp | –40°C to +85°C, qualified for industrial control and automotive body electronics |
Pinout & Package
Package: 8-pin SOIC (208-mil width), RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO/IO1 | Serial Output / Quad I/O Line 1 | Bi-directional data line for QPI read/write; shares function with standard SPI output |
| SI/IO0 | Serial Input / Quad I/O Line 0 | Bi-directional data line for QPI read/write; shares function with standard SPI input |
| WP#/IO2 | Write Protect / Quad I/O Line 2 | Hardware-level write lock when asserted low; doubles as QPI data line in quad mode |
| HOLD#/IO3 | Hold Input / Quad I/O Line 3 | Pauses ongoing transfer without chip deselect; doubles as QPI data line in quad mode |
| CLK | Clock Input | Synchronizes all SPI/QPI operations; max 133 MHz frequency defines system boot speed |
| CS# | Chip Select | Active-low enable for command decoding; required for multi-device bus arbitration |
| VCC | Power Supply | 3.0 V nominal supply; internal voltage regulator ensures stable core operation |
| VSS | Ground | Reference return path for all I/O and core circuits; must be low-impedance |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI (QPI) Mode | Enables 4x data bandwidth vs standard SPI, reducing boot time by up to 75% in XIP configurations |
| Flexible Sector Protection | Software- and hardware-based locking of individual 4-KB sectors prevents accidental firmware overwrite |
| Page Program Time | Typical 250 µs per 256-byte page, enabling fast incremental firmware patching |
| Endurance & Retention | 100,000 program/erase cycles and 20-year data retention at 85°C, validated per JEDEC standards |
| Security Lock Bits | One-time programmable (OTP) security registers prevent unauthorized readout of stored firmware |

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 |
|---|---|---|---|
| S25FL256SAGMFI000 | Same density and QPI interface, but 1.8 V core voltage; requires dual-supply design | Targeted at ultra-low-power IoT edge nodes, not industrial 3.3 V systems | Select only if system already uses 1.8 V I/O domain and needs lower active current |
| MX25L25645GMI-13G | 256 Mbit, 133 MHz, but lacks OTP security lock bits and has 10K-cycle endurance | Suitable for cost-sensitive consumer devices where firmware IP protection is non-critical | Choose when security and long-term field update reliability are secondary to BOM cost |
Compared with S25FL256SAGMFI000 and MX25L25645GMI-13G, the S25FL256LAGBHB033 uniquely combines industrial temperature operation, OTP security, and 100K-cycle endurance within a single 3.3 V supply footprint-making it optimal for safety-critical embedded boot applications.

FAQ
Is S25FL256LAGBHB033 pin-compatible with earlier S25FL256L variants?
Yes, it maintains identical 8-pin SOIC package and pinout with S25FL256LxxxB and S25FL256LxxxC revisions. The 'H' suffix denotes enhanced reliability screening per AEC-Q100 Grade 2, but mechanical and electrical interface remains unchanged.
Does this device support Dual and Quad SPI modes simultaneously?
No. It supports standard SPI (single I/O), Dual SPI (two I/O lines), and Quad SPI (four I/O lines) as mutually exclusive modes selected via status register configuration. Mode switching requires issuing specific instruction sequences and cannot occur mid-transfer.
What is the maximum allowable clock duty cycle variation for reliable QPI operation?
The device specifies 45–55% duty cycle tolerance for CLK at 133 MHz. Deviations beyond this range may cause setup/hold violations on IO0–IO3 lines, leading to data corruption during high-speed reads or writes.
Can the WP# pin be left unconnected in systems without hardware write protection?
No. WP# must be pulled high via ≥10 kΩ resistor to VCC when unused. Floating WP# may result in unintended write protection activation due to noise coupling, blocking firmware updates or configuration changes.
