Product details
Overview
S25FL132K0XNFIQ13 from Cypress Semiconductor is a 32-Mbit (4 Mbyte), 3.0 V serial NOR flash memory with SPI Multi-I/O interface, supporting Quad Read at up to 108 MHz (54 MB/s), uniform 4-kB sector and 64-kB block erase, and 100K program-erase cycles. It operates across –40 °C to +105 °C (Industrial Plus), features three 256-byte OTP security registers, and enables Execute-In-Place (XIP) in embedded boot code storage applications.
For engineers reviewing the S25FL132K0XNFIQ13 datasheet, S25FL132K0XNFIQ13 pinout, S25FL132K0XNFIQ13 application, or S25FL132K0XNFIQ13 equivalent, key selection considerations include quad-mode timing compliance, security register configuration, sector protection granularity, and migration path to S25FL064L for new designs.
Technical Context
This device implements JEDEC-standard SPI command set with support for modes 0 and 3, Serial Flash Discoverable Parameters (SFDP), and dual/quad I/O protocols using shared IO0–IO3 pins. The memory array uses 90 nm floating gate technology and supports volatile/non-volatile configuration registers for latency and drive strength tuning.
Hardware write protection is implemented via WP# and HOLD# inputs, while software protection leverages non-volatile status register bits, OTP security registers, and pointer-based block locking. Erase suspend/resume and program suspend/resume enable real-time host control during background operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 Mbyte) - fixed address space supporting boot code and firmware storage without external expansion. |
| Interface | SPI Multi-I/O (SIO/DIO/QIO) - reduces pin count vs parallel NOR; QIO mode disables WP#/HOLD# functionality. |
| Max Read Speed | 108 MHz clock, 54 MB/s (Quad Read) - enables XIP performance comparable to x16 parallel NOR at <1/3 signal count. |
| Erase Granularity | Uniform 4 kB sectors and 64 kB blocks - allows fine-grained firmware update partitioning and wear leveling. |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - validated for industrial lifecycle requirements. |
| Supply Voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and tolerant of brown-out conditions down to 2.6 V. |
| Temperature Range | –40 °C to +105 °C (Industrial Plus) - qualified for extended thermal environments in industrial controllers and automotive ECUs. |
Pinout & Package
Package: 8-contact USON (4 mm × 4 mm), lead-free, RoHS-compliant, moisture sensitivity level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable for command initiation; must be held low for full command duration including dummy cycles. |
| SCK | Serial Clock Input | Edge-triggered clock (modes 0/3); max 108 MHz in Quad Read; controls all data and instruction timing. |
| IO0 (SI) | Serial Data I/O (Input/Output) | Primary data line in SIO mode; bidirectional in DIO/QIO; carries instruction, address, and read/write data. |
| IO1 (SO) | Serial Data I/O (Input/Output) | Second data line in DIO/QIO; outputs read data in SIO; disabled when WP#/HOLD# active in QIO mode. |
| IO2 (WP#) | Write Protect Input / Quad I/O | Hardware lock for status register and memory sectors; functions as IO2 in QIO mode (WP# disabled). |
| IO3 (HOLD#) | Hold Input / Quad I/O | Suspends ongoing command mid-execution; functions as IO3 in QIO mode (HOLD# disabled). |
| VCC | Power Supply | 2.7–3.6 V core/I/O supply; decoupling capacitor required within 10 mm of pin per layout guidelines. |
| VSS | Ground | Digital ground reference; must be connected to system GND plane with low-inductance path. |
Key Features
| Feature | Design Value |
|---|---|
| Execute-In-Place (XIP) Support | Continuous and wrapped read modes reduce cache-miss penalty; enables direct CPU execution from flash without RAM copy. |
| Security Register Architecture | Three 256-byte OTP registers with lock-down until power cycle - stores cryptographic keys, calibration data, or device identity securely. |
| Flexible Protection Scheme | Top/bottom relative block protection (4 kB to full array) + software/hardware lock - prevents accidental overwrite in field-updatable systems. |
| Program/Erase Suspend | Allows host to pause background erase or program to service higher-priority interrupts - critical for real-time deterministic response. |
| SFDP Compliance (JESD216B) | Standardized parameter table accessible via READ SFDP command - enables automatic driver configuration without hard-coded timing values. |

FAQ
Is S25FL132K0XNFIQ13 recommended for new designs?
No. Cypress explicitly designates this part as "Not Recommended for New Design" and recommends migrating to S25FL064L. It remains available for legacy production and repair, but no new design-in should occur due to obsolescence risk and lack of long-term supply assurance.
What package does S25FL132K0XNFIQ13 use?
S25FL132K0XNFIQ13 uses an 8-contact USON package (4 mm × 4 mm), identified by suffix 'U' in the ordering code and documented as UNF008 in Cypress packaging nomenclature. It is lead-free, halogen-free, and MSL3 compliant.
Does it support Quad I/O mode with hardware write protection enabled?
No. When Quad I/O mode is active, IO2 (WP#) and IO3 (HOLD#) function exclusively as data lines; hardware write protection is disabled. Software-based protection via status register bits remains fully operational in all I/O modes.
How is security implemented in this device?
Security includes three 256-byte OTP registers, top/bottom block protection with 4 kB granularity, lock-down mode (protection persists until power cycle), and non-volatile status register bits. Unique 8-byte ID per device enables secure provisioning and anti-cloning in certified systems.
