Infineon Technologies S25FL032P0XNFI011

Overview

S25FL032P0XNFI011 from Cypress Semiconductor is a 32-Mbit, single-power-supply SPI Flash memory operating across 2.7 V to 3.6 V. It features uniform 64-KB sectors, 4-KB/8-KB sub-sectors, 256-byte page programming (1.5 ms typical), and Quad I/O FAST_READ at 80 MHz (40 MB/s). Used for firmware storage in industrial microcontroller boot loaders requiring secure, field-upgradable nonvolatile memory.

For engineers reviewing the S25FL032P0XNFI011 datasheet, S25FL032P0XNFI011 pinout, S25FL032P0XNFI011 application, or S25FL032P0XNFI011 equivalent, key selection criteria include sub-sector erase granularity, OTP security space (16 bytes + 490 bytes), W#/ACC-accelerated programming, CFI compliance, and industrial temperature range (–40°C to +85°C).

Technical Context

The S25FL032P implements a serial peripheral interface with five extended command sets enabling Dual Output Read, Quad Output Read, Dual I/O, Quad I/O, and Quad Page Programming - all using SI/IO0, SO/IO1, W#/ACC/IO2, and HOLD#/IO3 as bidirectional data lines. Its architecture supports simultaneous read-while-write via status register polling and includes dedicated OTP regions for secure device identification.

Memory protection relies on Status Register BP2–BP0 bits and hardware W#/ACC pin control, while power management includes Deep Power-Down mode (3 µA typical) and Standby Mode (80 µA typical). The device uses Cypress's 0.09 µm MirrorBit® process and is fully backward compatible with S25FL032A.

FAQ

Is S25FL032P0XNFI011 still in production?

No - Cypress officially retired the S25FL032P family and does not recommend it for new designs. However, Aetrix Electronics maintains legacy inventory with full traceability and supports existing production programs through lifecycle coordination and last-time-buy planning.

What package type does S25FL032P0XNFI011 use?

S25FL032P0XNFI011 uses the 8-contact WSON package (6 × 8 mm), identified by the 'N' in the part number suffix. It features an exposed thermal pad that must be connected to GND with zero voltage differential to ensure signal integrity and thermal reliability.

Can S25FL032P0XNFI011 be used with standard SPI controllers?

Yes - it supports standard SPI Mode 0 and Mode 3 protocols for basic read/write. Full feature utilization (e.g., Quad I/O, sub-sector erase) requires host firmware that implements Cypress-specific command opcodes (e.g., 0x6B for QIOR, 0x20 for P4E) defined in the datasheet.

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

No - the S25FL032P does not support true XIP execution. While fast Quad I/O read enables low-latency data streaming, code must be copied to RAM before execution. Host processors require explicit fetch-and-copy routines or external memory controllers with caching support.
