Infineon Technologies S25FL032P0XNFA013

Overview

S25FL032P0XNFA013 from Cypress Semiconductor is a 32-Mbit, single-supply (2.7–3.6 V) SPI NOR Flash memory with uniform 64-KB sectors, 4-KB/8-KB sub-sectors, 256-byte page size, and Quad I/O FAST_READ support up to 80 MHz (40 MB/s). It implements MirrorBit® 0.09 µm process technology and includes 16-byte factory- or customer-programmable OTP for secure identification. Used in embedded boot code storage and firmware update storage where SPI interface density and sector flexibility are required.

For engineers reviewing the S25FL032P0XNFA013 datasheet, S25FL032P0XNFA013 pinout, S25FL032P0XNFA013 application, or S25FL032P0XNFA013 equivalent, key selection criteria include sub-sector erase granularity (4-KB/8-KB), accelerated programming via W#/ACC pin, CFI compliance for host auto-detection, and industrial temperature range (–40°C to +85°C) with Pb-free, halogen-free USON package.

Technical Context

The S25FL032P0XNFA013 implements a serial peripheral interface (SPI) with standard, dual, and quad I/O modes, supporting READ, FAST_READ, DOR, QOR, DIOR, and QIOR commands. Its memory array is organized as 64 × 64-KB sectors, with top/bottom parameter blocks subdivided into thirty-two 4-KB sub-sectors each.

It features hardware-based memory protection using Status Register BP2–BP0 bits and W#/ACC pin control, supports Deep Power-Down mode (3 µA typical), and enables accelerated programming via external 9-V signal on W#/ACC. The device is CFI-compliant and provides JEDEC two-byte ID plus one-byte RES signature for legacy compatibility.

FAQ

Is S25FL032P0XNFA013 still recommended for new designs?

No. Cypress explicitly states this part is "Not Recommended for New Design" and designates S25FL064L as the official migration path. While fully functional and supported for existing production, new projects should adopt the higher-density, faster S25FL064L to ensure long-term supply and feature alignment.

What does the 'NFA013' suffix indicate in S25FL032P0XNFA013?

The suffix decodes as: N = 8-contact USON/WSON package, F = Pb-free, A = Industrial temperature (–40°C to +85°C), 013 = 13-inch tape-and-reel packaging. This confirms the device is in the 5 × 6 mm USON package with halogen-free, RoHS-compliant materials.

Can the W#/ACC pin be left unconnected?

No. W#/ACC must be actively driven: pulled low for standard write protection or supplied with 9 V for accelerated programming. Leaving it floating risks unintended write-enable states or latch-up. In non-accelerated operation, tie it to VCC via 10-kΩ resistor or drive it low with GPIO.

Does S25FL032P0XNFA013 support XIP (eXecute-In-Place)?

No. This device lacks an address bus and operates exclusively via SPI serial interface; it cannot be memory-mapped for direct CPU instruction fetch. XIP requires parallel or octal SPI NOR with address pins - a capability absent in the S25FL032P series.
