Product details

Overview

S25FL132K0XBHIS30 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 for industrial microcontrollers requiring XIP-capable, space-constrained non-volatile memory.

For engineers reviewing the S25FL132K0XBHIS30 datasheet, S25FL132K0XBHIS30 pinout, S25FL132K0XBHIS30 application, or S25FL132K0XBHIS30 equivalent, key selection criteria include Quad I/O timing compliance, 2.7–3.6 V supply range, Industrial Plus (−40 °C to +105 °C) operation, and security register OTP configuration support.

Technical Context

This device implements JEDEC-standard SPI command set with full Multi-I/O support-Single, Dual, and Quad Read/Program modes-and includes Serial Flash Discoverable Parameters (SFDP) for automatic configuration. Its 90 nm Floating Gate architecture enables fast page programming (700 µs typical for 256-byte page) and supports Program/Erase Suspend & Resume for real-time system responsiveness.

The memory integrates three 256-byte Security Registers with OTP lock, pointer-based block protection, and 8-byte unique ID. Protection is enforced via non-volatile status bits, hardware WP#/HOLD# pins, and software commands-including Lock-Down until power cycle-ensuring robust firmware integrity in mission-critical boot applications.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	32 Mbit (4 Mbyte) - sufficient for full MCU boot image + firmware update partition in compact embedded systems
Interface	SPI Multi-I/O (x1/x2/x4) - reduces pin count vs parallel NOR while maintaining XIP performance up to 54 MB/s
Max Clock Rate	108 MHz (Quad Read) - enables cache-line-aligned wrapped reads for efficient instruction fetch in real-time OS
Erase Granularity	4 kB sectors / 64 kB blocks - allows fine-grained firmware updates without disturbing adjacent functional partitions
Endurance & Retention	100K program-erase cycles / 20-year data retention - validated for industrial lifecycle requirements without refresh
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 under-hood automotive and high-ambient industrial control units

Pinout & Package

Package: 8-contact USON (4 mm × 4 mm), RoHS-compliant, moisture-sensitive level 3 (MSL-3).

Pin/Terminal	Circuit Role	Design Meaning
CS#	Chip Select	Active-low enable for SPI command sequence; must be held low for entire transaction including dummy cycles
SCK	Serial Clock	Input clock synchronizing all I/O transfers; supports modes 0 and 3; max 108 MHz in Quad mode
IO0 (SI)	Serial Input / Data Line 0	Primary data input in Single I/O; bidirectional in Dual/Quad modes; used for command/address/data ingress
IO1 (SO)	Serial Output / Data Line 1	Primary data output in Single I/O; bidirectional in Dual/Quad modes; carries read data and status responses
IO2 (WP#)	Write Protect Input	Hardware-level protection override; low = enables write/erase lock-down; disabled when Quad mode active
IO3 (HOLD#)	Hold Input	Suspends ongoing command mid-cycle without CS# deassertion; resumes on next SCK edge; disabled in Quad mode
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 PCB ground plane with low-inductance path

Key Features

Feature	Design Value
Execute-In-Place (XIP) Optimization	Continuous and wrapped read modes reduce instruction fetch latency to ≤8 clocks per access, enabling deterministic real-time code execution directly from flash
Security Register Architecture	Three 256-byte OTP-protected registers store cryptographic keys, secure boot parameters, and device-specific credentials-preventing cloning or unauthorized firmware injection
Flexible Block Protection	Top/bottom relative protection range configurable from 4 kB to full array via status register bits or hardware WP#, allowing dynamic lockdown of bootloader region during field updates
Program/Erase Suspend & Resume	Interrupts active erase or program operations to service higher-priority host requests, then resumes from exact byte address-critical for time-sensitive interrupt handling
JEDEC SFDP Compliance	Self-describing parameter table (JESD216B) enables automatic driver initialization without hard-coded timing or configuration constants in host firmware

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
S25FL064L0XMFI001	64 Mbit density, 133 MHz Quad Read, 1.8 V / 3.0 V dual supply, enhanced SFDP v1.6, no HOLD#/WP# in QPI mode	Supports newer host controllers requiring higher bandwidth and dual-voltage flexibility; lacks pointer-based security but adds volatile configuration register	Select when migrating to Cypress's current-generation FL-L family for extended longevity and improved read throughput; requires PCB redesign due to different pinout (16-pin SOIC)
MX25L3233FZBI-10G	32 Mbit, 104 MHz Quad Read, 2.7–3.6 V, 4 kB sectors, no OTP security registers, no SFDP, simpler command set	Lower-cost alternative for non-security-critical applications; lacks security registers, suspend/resume, and wrapped read mode	Choose for cost-sensitive consumer IoT where firmware integrity is managed externally; verify compatibility with existing driver stack due to missing SFDP and command differences

Compared with S25FL132K0XBHIS30, the S25FL064L offers higher density and speed but requires board redesign, while the MX25L3233F provides pin-compatible drop-in replacement only for basic read/write use cases-lacking security, suspend/resume, and XIP optimizations critical for industrial boot applications.

FAQ

Is S25FL132K0XBHIS30 still recommended for new designs?

No. Cypress explicitly designates this part as "Not Recommended for New Design" and recommends migration to the S25FL064L family. However, Aetrix Electronics maintains active inventory and supply chain support for legacy industrial and automotive programs requiring continued production continuity and obsolescence mitigation.

What package does S25FL132K0XBHIS30 use, and is it RoHS-compliant?

S25FL132K0XBHIS30 uses an 8-contact USON package (4 mm × 4 mm, UNF008 footprint) with exposed pad. It is fully RoHS-compliant and rated MSL-3, requiring bake conditioning before reflow if exposed to ambient humidity beyond floor life limits.

Does this device support Quad SPI mode with hardware write protection enabled?

No. When Quad I/O mode is active, the IO2 (WP#) and IO3 (HOLD#) pins are repurposed as data lines and hardware write protection is disabled. Software-based protection via status register bits remains fully functional in all modes.

Can S25FL132K0XBHIS30 be used in AEC-Q100 Grade 2 automotive applications?

Yes. The "I" in the part number denotes Industrial Plus grade (−40 °C to +105 °C), which satisfies AEC-Q100 Grade 2 requirements. Cypress documentation confirms qualification for automotive applications, including validation of 100K endurance and 20-year retention under thermal cycling stress.
