Product details
Overview
S25FL132K0XMFIQ13 from Cypress Semiconductor is a 32-Mbit (4 Mbyte), 3.0 V serial NOR flash memory with SPI Multi-I/O interface, supporting Normal, Fast, Dual, and Quad Read modes up to 108 MHz (54 MB/s), uniform 4-kB sector and 64-kB block erase, and 100K program-erase cycles - deployed in embedded boot code storage, firmware update partitions, and XIP-capable microcontroller systems.
For engineers reviewing the S25FL132K0XMFIQ13 datasheet, S25FL132K0XMFIQ13 pinout, S25FL132K0XMFIQ13 application, or S25FL132K0XMFIQ13 equivalent, key selection considerations include quad I/O read bandwidth, OTP-protected security registers, industrial temperature support (−40 °C to +105 °C), and migration path to S25FL064L for new designs.
Technical Context
This SPI flash implements JEDEC-standard Serial Flash Discoverable Parameters (SFDP) for runtime configuration discovery and supports command-set compatibility with prior S25FL-K families while adding volatile/non-volatile configuration register options and variable dummy-cycle latency tuning for optimized timing across clock rates.
The device uses 90 nm floating gate technology, operates from 2.7 V to 3.6 V, and integrates hardware write protection (WP#), hold functionality (HOLD#), and three 256-byte one-time-programmable security registers - enabling secure boot partitioning, unique device ID binding, and pointer-based block protection for firmware integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 Mbyte) - sufficient for full MCU boot image plus parameter storage in space-constrained edge nodes |
| Read Throughput | 54 MB/s (Quad Read @ 108 MHz) - enables near-parallel-NOR performance with only 6 pins |
| Erase Granularity | Uniform 4 kB sectors and 64 kB blocks - allows fine-grained firmware update without disturbing adjacent code |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - validated for industrial lifecycle deployments |
| Operating Temp | −40 °C to +105 °C (Industrial Plus) - qualified for under-hood automotive and high-ambient industrial control |
| Security Features | Three 256-byte OTP registers + 8-byte unique ID + software/hardware lock-down - supports secure boot chain verification |
| Supply Voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and brown-out tolerant power domains |
Pinout & Package
Package: 8-contact USON (4 mm × 4 mm), RoHS-compliant, moisture-sensitive level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable for SPI command initiation; must be deasserted between commands to reset interface state |
| SCK | Serial Clock Input | Edge-triggered clock up to 108 MHz; phase/polarity modes 0 and 3 supported for host controller compatibility |
| IO0 (SI) | Serial Data I/O 0 | Primary bidirectional data line; used for instruction/address/data in Single I/O mode; IO0/IO1 in Dual; all four in Quad |
| IO1 (SO) | Serial Data I/O 1 | Secondary bidirectional line; enables dual-bit transfers; disabled when Quad mode active and WP#/HOLD# repurposed |
| IO2 (WP#) | Write Protect Input | Hardware-level protection override; low = disable writes/erases; functional only in Single/Dual mode |
| IO3 (HOLD#) | Hold Input | Suspends ongoing command mid-execution; resumes on next SCK edge; not available in Quad mode |
| VCC | Power Supply | 2.7–3.6 V core/I/O supply; internal regulation ensures stable operation across voltage and temperature |
| VSS | Ground | Signal reference for all I/O and core logic; requires low-impedance connection to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read (QIO) Mode | Enables 54 MB/s continuous throughput using all four I/O lines - eliminates need for parallel NOR in cost-sensitive XIP designs |
| Program/Erase Suspend | Allows background erase or program to pause for higher-priority reads - critical for real-time firmware update without system stall |
| Security Register OTP | Three independent 256-byte one-time-programmable regions - used for cryptographic keys, calibration data, or secure boot manifests |
| Variable Dummy Cycles | Configurable latency setting per read command - balances access time vs. maximum clock rate across PCB trace lengths |
| Block Protection Range | Top/bottom relative 4 kB–full-memory protection via status register bits - enables flexible partitioning of boot vs. app firmware |
Applications
| Industrial PLC Firmware Storage | Automotive ADAS Boot Memory |

Use Value: Variable dummy cycle tuning compensates for signal integrity degradation across long PCB traces in meter base designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064L0XMFIQ13 | 64 Mbit density, 133 MHz Quad Read, 2.7–3.6 V, same USON-8 package, enhanced SFDP v1.6 | Higher capacity and speed; supports larger firmware images and faster OTA updates | Recommended for new designs requiring extended longevity and Cypress's current-generation feature set |
| MX25L3233FZNI-10G | 32 Mbit, 104 MHz Quad Read, 2.7–3.6 V, 8-pin WSON, no OTP security registers or pointer-based protection | Lacks hardware security features; suitable where cost is primary constraint and firmware integrity is managed externally | Consider only if security registers and AEC-Q100 qualification are not required |
Compared with S25FL132K0XMFIQ13, S25FL064L0XMFIQ13 offers higher density and speed with identical footprint and improved SFDP compliance, while MX25L3233FZNI-10G provides basic SPI flash functionality at lower cost but omits security and automotive qualification.

Manufacturer
Cypress Semiconductor (now part of Infineon Technologies) is a fabless semiconductor company specializing in embedded systems solutions, including microcontrollers, connectivity, and non-volatile memory.
The S25FL1-K family was designed for high-reliability embedded boot and firmware storage, targeting industrial, automotive, and medical applications requiring secure, long-life serial flash with XIP support.
FAQ
Is S25FL132K0XMFIQ13 still recommended for new designs?
No - Cypress explicitly states this part is "Not Recommended for New Design" and designates S25FL064L as the factory-recommended migration path. It remains available for legacy production and repair, but new projects should adopt the S25FL-L family for extended support, higher performance, and updated security features.
What does the 'XMF' in the part number indicate?
The 'XMF' suffix denotes an 8-contact USON (4 mm × 4 mm) package with industrial-plus temperature range (−40 °C to +105 °C) and lead-free/RoHS-compliant construction. The 'IQ13' indicates tape-and-reel packaging with 3,000 units per reel and Infineon's standard quality screening.
Can S25FL132K0XMFIQ13 operate in Quad I/O mode while using WP# or HOLD#?
No - when Quad I/O mode is enabled, IO2 (WP#) and IO3 (HOLD#) are repurposed as additional data lines (IO2 and IO3). Hardware write protection and hold functionality are disabled in Quad mode; protection must be managed via software commands or external logic.
How is the 8-byte unique ID accessed?
The 8-byte unique ID is read using the Read Unique ID command (ABh), which outputs the value starting from address 0x00. This ID is factory-programmed, non-erasable, and distinct across all devices - used for device authentication, license binding, or anti-cloning in secure systems.
