Product details
Overview
S25FL032P0XNFV000 from Cypress Semiconductor is a 32-Mbit, single-power-supply SPI Flash memory operating from 2.7 V to 3.6 V, featuring uniform 64-KB sectors, 4-KB/8-KB sub-sectors, 256-byte page programming, and Quad I/O FAST_READ at 80 MHz (40 MB/s). It supports OTP identification (16 bytes + 490 bytes), CFI compliance, and accelerated programming via W#/ACC pin. Used in firmware storage for industrial microcontrollers and boot code retention in automotive infotainment systems.
For engineers reviewing the S25FL032P0XNFV000 datasheet, S25FL032P0XNFV000 pinout, S25FL032P0XNFV000 application, or S25FL032P0XNFV000 equivalent, key selection considerations include sector/sub-sector erase granularity, 100,000-cycle endurance, Deep Power-Down (3 µA), Quad Page Programming support, and automotive-grade temperature range (–40°C to +105°C).
Technical Context
The S25FL032P implements a serial peripheral interface with five extended command sets: Dual Output Read (DOR), Quad Output Read (QOR), Dual I/O High Performance Read (DIOR), Quad I/O High Performance Read (QIOR), and Quad Page Program (QPP). All operate up to 80 MHz clock rate with dedicated I/O pin reconfiguration (SI/IO0, SO/IO1, W#/ACC/IO2, HOLD#/IO3).
Memory architecture includes two configurable parameter blocks (top/bottom 64-KB sectors), each subdivided into sixteen 4-KB sub-sectors or eight 8-KB sub-sectors. Protection is enforced via Status Register BP2–BP0 bits and hardware W#/ACC pin assertion, enabling selective read-only locking of memory regions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 MB) - sufficient for full MCU boot image and configuration data in space-constrained embedded designs |
| Supply Voltage | 2.7 V to 3.6 V - compatible with standard 3.3-V logic rails without level-shifting |
| Read Speed | QUAD I/O FAST_READ: 80 MHz clock / 40 MB/s effective - enables rapid firmware loading in real-time boot sequences |
| Erase Granularity | 64-KB sector, 4-KB & 8-KB sub-sector - allows fine-grained field updates without full device reprogramming |
| Endurance | 100,000 program/erase cycles per sector - supports frequent OTA update cycles in connected devices |
| Data Retention | 20 years typical - ensures long-term reliability in automotive and industrial deployments |
| Power Modes | Deep Power-Down: 3 µA typical - critical for battery-backed systems requiring ultra-low standby leakage |
Pinout & Package
Package: 8-contact WSON (6 × 8 mm), RoHS-compliant, lead-free, with exposed thermal pad (GND-connected per layout guidelines).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable for SPI transaction initiation; required falling edge after power-up before command acceptance |
| SO/IO1 | Serial Output / I/O | Primary data output in standard mode; becomes bidirectional I/O in Dual/Quad I/O modes for parallelized reads/writes |
| W#/ACC/IO2 | Write Protect / Acceleration / I/O | Hardware write lock when low; enables accelerated programming when driven to 9 V; functions as I/O in Quad modes |
| HOLD#/IO3 | Hold Input / I/O | Pauses ongoing SPI transfer without chip deselect; acts as I/O pin in Quad I/O and QPP operations |
| SI/IO0 | Serial Input / I/O | Command/address/data input in standard mode; bidirectional in Dual/Quad I/O and QPP for expanded bandwidth |
| SCK | Serial Clock Input | Edge-triggered timing source: rising edge latches input, falling edge triggers output |
| VCC | Supply Voltage | Single 2.7–3.6 V rail powers all read/write/erase operations; internal charge pumps generate high-voltage programming pulses |
| GND | Ground Reference | Reference for all I/O and internal circuitry; exposed pad must be tied to GND with zero voltage differential per layout spec |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O High Performance Read (QIOR) | Enables 40 MB/s effective throughput using four pins simultaneously - reduces boot time by >2× vs. standard SPI |
| Configurable Parameter Block | Top or bottom 64-KB sector split into 4-KB/8-KB sub-sectors - supports secure bootloader partitioning and incremental firmware patching |
| One-Time Programmable (OTP) Area | 16-byte factory-programmable ID + 490-byte user-programmable space - provides tamper-resistant device identity and calibration storage |
| Common Flash Interface (CFI) Compliance | Allows host system to auto-detect geometry, timing, and command set - simplifies firmware abstraction layer across flash vendors |
| Accelerated Programming Mode | 9-V signal on W#/ACC pin reduces page program time to 1.5 ms typical - improves manufacturing test throughput and field update speed |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064L | 64-Mbit density, same 2.7–3.6 V supply, identical pinout and command set, enhanced 133-MHz Quad I/O performance | Recommended for new designs requiring higher capacity or faster read throughput; supersedes S25FL032P per Cypress migration path | Select when design requires ≥64 Mbit or needs future-proofing against obsolescence; drop-in compatible with minor firmware tuning |
| MX25L3233F | 32-Mbit, 2.7–3.6 V, supports DTR mode up to 133 MHz, no OTP area, different status register layout | Lacks OTP security and parameter block flexibility; suited for cost-sensitive consumer applications without secure ID needs | Choose only if OTP and sub-sector protection are not required; verify command compatibility and timing margins in existing firmware |
Compared with S25FL032P0XNFV000, S25FL064L offers double capacity and higher speed with full backward compatibility, while MX25L3233F trades OTP and flexible protection for lower unit cost-making it viable only where security and granular erase are non-critical.

FAQ
Is S25FL032P0XNFV000 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and recommends migrating to S25FL064L. It remains available for legacy production and repair, with full technical documentation and known lifecycle support through authorized channels.
What does the 'V' suffix in S25FL032P0XNFV000 indicate?
The 'V' denotes Automotive In-Cabin qualification (–40°C to +105°C) per AEC-Q100 stress testing standards. This includes extended temperature operation, enhanced ESD tolerance, and rigorous reliability validation beyond industrial-grade parts.
Can the OTP area be reprogrammed after initial programming?
No. The 16-byte factory OTP region is permanently locked after programming. The additional 490-byte user OTP space can be programmed once and then locked via the OTP Lock command (0x87); subsequent writes to locked OTP return status error and have no effect.
How does the W#/ACC pin function in accelerated programming mode?
In accelerated mode, applying 9 V (±0.5 V) to W#/ACC reduces typical page program time from ~3 ms to 1.5 ms. This requires external voltage boosting circuitry and must be enabled via Status Register bit SRP0=1 and proper command sequencing (WREN followed by QPP).
