Product details

Overview

S25FL208K0RMFI013 from Cypress Semiconductor is an 8-Mbit serial NOR flash memory with uniform 4-kB sectors, supporting standard and dual-output SPI interfaces up to 76 MHz, 2.7–3.6 V single-supply operation, and 100k program/erase cycles - deployed in embedded boot code storage and firmware update partitions.

For engineers reviewing the S25FL208K0RMFI013 datasheet, S25FL208K0RMFI013 pinout, S25FL208K0RMFI013 application, or S25FL208K0RMFI013 equivalent, key selection criteria include sector granularity (4 kB), dual-output read capability, hardware write protection via WP# and HOLD#, and industrial temperature range (–40°C to +85°C).

Technical Context

The S25FL208K0RMFI013 implements a uniform sector architecture with 256 × 4-kB sectors and 16 × 64-kB blocks, enabling fine-grained firmware partitioning. It supports SPI modes 0 and 3 with rising-edge input sampling and falling-edge output timing.

Dual Output Read (0x3B) repurposes SI/IO0 as a second data output during fast reads, doubling throughput versus standard SPI. The device integrates non-volatile block protect bits (BP0–BP3), SRP bit, and hardware WP#/HOLD# pins for layered write protection without software intervention.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	8 Mbit (1,048,576 bytes), organized as 4,096 pages × 256 bytes - supports byte-aligned firmware image storage and incremental updates.
Supply Voltage	2.7–3.6 V - compatible with 3.3 V logic systems without level-shifting; no separate VIO required.
Max Clock Frequency	76 MHz for both Standard Read (0x03) and Dual Output Read (0x3B) - enables ≤133 ns per byte access in dual mode.
Erase Granularity	Uniform 4-kB sectors and 64-kB blocks - allows independent erasure of bootloader, config, and application sections.
Endurance & Retention	100,000 program/erase cycles; 20-year data retention at 85°C - validated for long-life industrial deployments.
Power Consumption	12 mA active current; 15 µA standby - suitable for low-duty-cycle firmware fetch and battery-backed systems.
Package	8-pin SOIC (208-mil), RoHS-compliant - surface-mount compatible with standard reflow profiles and legacy PCB footprints.

Pinout & Package

8-pin SOIC (208-mil) package with gull-wing leads, JEDEC MS-012AC compliant, body size 7.62 mm × 5.33 mm, lead pitch 1.27 mm.

Pin/Terminal	Circuit Role	Design Meaning
CS#	Chip Select (active-low)	Enables SPI communication; high-Z SO when deasserted; required to transition H→L after power-up before first command.
SCK	Serial Clock Input	Drives all timing; supports SPI modes 0 and 3; rising edge latches input, falling edge outputs data.
SI/IO0	Serial Input / Dual Output	Input for commands/addresses/data; becomes second data output during Fast Read Dual Output (0x3B) instruction.
SO	Serial Output	Primary data output; driven during all read operations; high-impedance during HOLD# assertion.
WP#	Hardware Write Protect	Locks status register when asserted low; works with BP bits to enforce hardware-level memory partition protection.
HOLD#	Communication Pause	Halts ongoing SPI transfer without deselecting chip; preserves internal state while sharing bus with other peripherals.
VCC	Power Supply	2.7–3.6 V supply; decoupling capacitor (0.1 µF) required within 10 mm of pin per layout guidelines.
GND	Ground Reference	Signal and power return; must be connected to low-impedance ground plane to maintain timing integrity at 76 MHz.

Key Features

Feature	Design Value
Uniform 4-kB Sector Architecture	Enables precise firmware partitioning (e.g., bootloader, parameter table, app code) without wasted erase overhead.
Dual Output Read (0x3B)	Delivers 152 MB/s effective throughput (76 MHz × 2 bits/cycle), accelerating boot-time code shadowing to RAM.
Hardware + Software Write Protection	Combines WP# pin control with non-volatile BP0–BP3 bits to lock critical sectors independently of host firmware state.
Auto-Increment Read Capability	Supports continuous sequential reads across page boundaries without address retransmission - reduces host CPU overhead.
JEDEC ID & Manufacturer ID Support	Enables runtime device identification (0x90, 0x9F commands) for BOM validation and field firmware compatibility checks.

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
S25FL208K0XMFI010	Same die, 150-mil SOIC package; identical electrical specs and command set.	Requires different PCB footprint; thermal dissipation marginally lower due to smaller package size.	Select only if legacy board design mandates 150-mil SOIC; otherwise prefer 208-mil for improved manufacturability.
MX25L8006EM1I-12G	8-Mbit SPI flash with 104 MHz max clock; lacks Dual Output Read; uses different status register map and protection scheme.	Not drop-in; requires firmware driver modification for erase/write sequences and protection enablement.	Choose only when higher clock rate is critical and dual-output functionality is unused; verify BP bit mapping compatibility.

Compared with S25FL208K0XMFI010, the 0RMFI013 offers better thermal margin and solder joint reliability in reflow; versus MX25L8006EM1I-12G, it delivers faster effective read bandwidth and more flexible hardware/software write protection - critical for secure firmware update architectures.

FAQ

Is S25FL208K0RMFI013 pin-compatible with earlier S25FLxxx generations?

No. While sharing the same 8-pin SOIC footprint, the S25FL208K uses updated command codes and status register definitions versus S25FL0xx devices. Migration requires firmware driver updates for erase, write protection, and ID read sequences - especially BP bit handling and Dual Output Read enablement.

Does S25FL208K0RMFI013 support Quad SPI mode?

No. The S25FL208K0RMFI013 supports only Standard SPI and Dual Output SPI (using SI/IO0 and SO). It does not implement Quad SPI (QSPI) commands or four-line data transfer. Devices with Quad SPI capability belong to the S25FL512S or S25FS series.

What is the purpose of the HOLD# pin during multi-device SPI bus sharing?

HOLD# allows the S25FL208K0RMFI013 to pause an ongoing SPI transaction (e.g., a long read) without releasing CS#, preserving internal address and state. This lets another device seize the shared SCK/SI/SO lines immediately, then resume the flash operation once HOLD# is deasserted - eliminating bus arbitration delays and command restart overhead.

How does hardware write protection interact with software block protection bits?

WP# pin assertion (low) locks the status register from writes, preventing modification of BP0–BP3 and SRP bits. When WP# is high, those bits remain modifiable via Write Status Register (0x01) command. This two-layer scheme ensures that even if firmware is compromised, critical sectors remain protected by hardware-enforced register lockdown.
