Product details
Overview
S25FL204K0TMFI013 from Cypress Semiconductor is a 4-Mbit (512 kB) 3.0 V SPI Flash memory with uniform 4-kbyte sectors and 64-kbyte blocks, supporting standard and dual-output SPI up to 85 MHz, 100k program/erase cycles, and 20-year data retention - deployed in microcontroller boot code storage, firmware update partitions, and configuration parameter retention for industrial controllers.
For engineers reviewing the S25FL204K0TMFI013 datasheet, S25FL204K0TMFI013 pinout, S25FL204K0TMFI013 application, or S25FL204K0TMFI013 equivalent, key selection criteria include sector granularity (4 kB), dual-output read capability, hardware write protection via WP# and status register, and industrial temperature range (–40°C to +85°C) compliance.
Technical Context
The S25FL204K0TMFI013 implements a uniform flash architecture with 128 × 4-kB sectors and 8 × 64-kB blocks, enabling fine-grained firmware partitioning and secure over-the-air (OTA) update staging. Its dual-output SPI mode (3Bh command) doubles effective read bandwidth by driving data simultaneously on SI/IO0 and SO pins under continuous CS# assertion.
It supports JEDEC-standard manufacturer/device ID reads (90h, 9Fh), status register polling during erase/program operations, and deep power-down mode (B9h) with 15 µA standby current. The HOLD# pin enables multi-device SPI bus arbitration without deselecting the chip, preserving internal state across host interrupt latency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L4006EM1I-12G | 4 Mbit, 104 MHz max clock, 3.3 V only, no dual-output read mode | Lacks dual-output acceleration; requires higher clock rate to match throughput | Select when maximum read speed is less critical than cost and vendor diversification |
| W25Q40EWUXIE | 4 Mbit, 133 MHz, Quad SPI support, 1.8 V/3.3 V dual supply | Supports QPI for 4× bandwidth but requires additional IO lines and controller support | Select when migrating to quad-interface platforms or needing lower voltage operation |
Compared with MX25L4006EM1I-12G and W25Q40EWUXIE, the S25FL204K0TMFI013 uniquely balances dual-output performance, industrial temperature reliability, and pin-compatible SOIC footprint - making it optimal for legacy SPI designs requiring upgrade headroom without board redesign.

FAQ
What SPI modes does the S25FL204K0TMFI013 support?
The device supports SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1). In both modes, data is latched on the rising edge of SCK and output on the falling edge. The difference lies only in idle clock polarity, ensuring compatibility with most MCU SPI peripherals without protocol translation.
Can the S25FL204K0TMFI013 be used in dual-output mode with any host controller?
Yes - dual-output mode (Fast Read Dual Output, command 3Bh) requires only standard SPI hardware: CS#, SCK, SI/IO0, and SO pins. No special controller support is needed beyond sending the correct command sequence and sampling both SI/IO0 and SO during read cycles while CS# remains asserted.
How does hardware write protection interact with software protection bits?
WP# pin controls write access to the status register only. When WP# is low, the Block Protect (BP0–BP3) and Status Register Protect (SRP) bits cannot be modified - preventing changes to memory protection settings even if software attempts to rewrite them. This creates a physical enforcement layer for critical firmware regions.
Is the S25FL204K0TMFI013 pin-compatible with earlier Spansion S25FLxxx devices?
Yes - it maintains identical 8-pin SOIC pinout, command set, and electrical characteristics with prior S25FL204K variants (e.g., S25FL204K0XMFI010). Migration requires no PCB change; only firmware verification for timing margins and status register initialization is recommended.
