Infineon Technologies S25FL216K0PMFI011

Overview

S25FL216K0PMFI011 from Cypress Semiconductor is a 16-Mbit serial NOR flash memory with uniform 4-kB sectors, supporting standard and dual-output SPI interfaces up to 65 MHz, operating across 2.7–3.6 V, and delivering 12 mA active current and 15 µA standby current for embedded code storage in microcontroller boot applications.

For engineers reviewing the S25FL216K0PMFI011 datasheet, S25FL216K0PMFI011 pinout, S25FL216K0PMFI011 application, or S25FL216K0PMFI011 equivalent, key selection criteria include sector granularity (4 kB), dual-output read capability, JEDEC ID support, hardware write protection via WP# and HOLD#, and industrial temperature range (–40°C to +85°C).

Technical Context

The S25FL216K0PMFI011 implements a uniform sector architecture with 512 × 4-kB sectors and 32 × 64-kB blocks, enabling flexible firmware partitioning and over-the-air update management. It supports SPI modes 0 and 3 with rising-edge input sampling and falling-edge output timing.

Dual-output read (command 0x3B) uses SI/IO0 and SO simultaneously to double data throughput versus standard SPI reads, while internal status register bits (BP0–BP3, SRP) enable software-configurable sector-level write protection independent of WP# pin state.

FAQ

Does S25FL216K0PMFI011 support Quad SPI mode?

No. The S25FL216K0PMFI011 supports only standard SPI and dual-output SPI (using SI/IO0 and SO). It does not implement Quad SPI commands or QPI mode. Its instruction set includes Fast Read Dual Output (0x3B) but lacks 0x6B (Quad Output Read) or 0xEB (Quad IO Read) opcodes per the official datasheet.

What is the minimum pulse width for the HOLD# signal to enter hold state?

The HOLD# signal must remain low for at least one full SCK cycle after CS# is asserted low to reliably enter hold mode. The device samples HOLD# on the falling edge of SCK, and the hold condition becomes active once SCK reaches logic low - no minimum pulse width is specified beyond synchronization with the clock domain.

Can WP# be used to protect only specific sectors?

WP# alone cannot protect individual sectors - it globally disables status register writes. Sector-level protection requires configuring BP0–BP3 bits in the status register, which can be locked permanently via the SRP bit. WP# acts as an override: when asserted low, it prevents *any* status register modification, thereby freezing all BP bit settings.

Is the 8-pin SOIC package lead-free and RoHS compliant?

Yes. The "F" in the part number S25FL216K0PMFI011 denotes a lead-free (Pb-free) package, and the datasheet explicitly states all Pb-free packages are RoHS compliant. The 208-mil SOIC package meets EU RoHS Directive 2011/65/EU and related exemptions.
