Product details
Overview
S25FL132K0XBHB020 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 108 MHz and delivering up to 54 MB/s continuous data transfer. It features uniform 4 kB sector and 64 kB block erase, 100K program-erase cycles, 20-year data retention, and hardware/software write protection. Used in embedded boot code storage and XIP applications requiring compact, low-pin-count non-volatile memory.
For engineers reviewing the S25FL132K0XBHB020 datasheet, S25FL132K0XBHB020 pinout, S25FL132K0XBHB020 application, or S25FL132K0XBHB020 equivalent, key selection criteria include Quad I/O timing compliance, industrial temperature support (−40 °C to +105 °C), security register OTP configuration, and migration path to S25FL064L for new designs.
Technical Context
This device implements JEDEC-standard SPI command set with modes 0 and 3 clock polarity/phase, supports Serial Flash Discoverable Parameters (SFDP) for runtime configuration, and enables Execute-In-Place (XIP) via Continuous and Wrapped Read modes. Its 90 nm floating gate technology ensures stable operation across Industrial Plus (−40 °C to +105 °C) and AEC-Q100 Grade 2 automotive conditions.
The memory integrates three 256-byte one-time-programmable (OTP) security registers, pointer-based block protection, and dual protection mechanisms-software command lock and hardware WP#/HOLD# inputs-with Quad I/O disabling WP#/HOLD# when active. Erase suspend/resume and program suspend/resume provide real-time command interruption capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 Mbyte) - sufficient for full firmware images in resource-constrained microcontrollers |
| Interface | SPI Multi-I/O (SIO/DIO/QIO) - reduces signal count vs parallel NOR while maintaining high throughput |
| Max Read Speed | 108 MHz Quad Read - enables 54 MB/s burst transfer, matching x16 parallel NOR performance |
| Erase Granularity | Uniform 4 kB sectors and 64 kB blocks - supports fine-grained firmware updates without full chip erase |

| IO1 (SO) | Serial Data I/O (Input/Output) | Second bidirectional line; enables dual-bit transfers and quad-mode data paths |
| IO2 (WP#) | Write Protect Input | Hardware-level protection; disables program/erase when asserted low (disabled in Quad mode) |
| IO3 (HOLD#) | Hold Input | Suspends ongoing command mid-execution; resumes on deassertion (disabled in Quad mode) |
| VCC | Power Supply | Single 2.7–3.6 V supply; powers core logic and I/O buffers; no separate VIO required |
| VSS | Ground | Reference return path for all signals and internal circuitry; requires low-impedance PCB connection |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064L0XMFI000 | 64 Mbit density, 133 MHz Quad Read, 1.8 V/3.0 V dual supply, enhanced SFDP v1.6, 200K endurance | Supports larger firmware images and higher clock rates; requires voltage translation if interfacing with legacy 3.3 V hosts | Select for new designs needing extended density, longer lifecycle, and future-proof SFDP compatibility |
| MX25L3233FZNI-10G | 32 Mbit, 104 MHz Quad Read, single 2.7–3.6 V supply, no OTP security registers, no program suspend/resume | Lacks hardware security and real-time command interruption - suitable only for cost-sensitive, non-security-critical applications | Consider only where BOM cost is primary constraint and security/robustness requirements are minimal |
Compared with S25FL132K0XBHB020, S25FL064L offers higher density and endurance for next-gen platforms, while MX25L3233F provides basic functionality at lower cost but omits critical reliability and security features required in industrial and automotive use.

FAQ
Is S25FL132K0XBHB020 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, but lacks long-term roadmap support, updated qualification, or newer feature sets like enhanced SFDP or dual-voltage operation.
What package does S25FL132K0XBHB020 use?
S25FL132K0XBHB020 uses an 8-contact WSON package (5 mm × 6 mm, code WND008), with exposed thermal pad, RoHS-compliant, and moisture sensitivity level 3. Pinout matches industry-standard SPI flash layout for drop-in replacement within same footprint constraints.
Does this device support Execute-In-Place (XIP)?
Yes. It supports efficient XIP via Continuous Read Mode (8-clock overhead per access) and Wrapped Read Mode (cache-line optimized). Combined with 108 MHz Quad Read, it delivers 54 MB/s throughput - sufficient for direct code execution in Cortex-M and RISC-V microcontrollers without external RAM buffering.
How is data protection implemented on this flash?
Data protection uses layered mechanisms: hardware WP#/HOLD# pins, software command lock (via Status Register bits), non-volatile configuration, OTP-locked security registers, and top/bottom block protection ranges configurable down to 4 kB granularity - enabling bootloader isolation and secure key storage.
