General Description
4
The S25FL004K (4-Mbit), S25FL008K (8-Mbit), and S25FL016K (16-Mbit) Serial Flash memories provide an
ideal storage solution for systems with limited space, pins and power. The devices offer flexibility and
performance well beyond ordinary Serial Flash devices. They are ideal for code shadowing to RAM,
executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The devices operate on a
single 2.7V to 3.6V power supply with current consumption as low as 4 mA active and 1 µA for deep power-
down. All devices are offered in space-saving packages.
The S25FL004K, S25FL008K, and S25FL016K support the standard Serial Peripheral Interface (SPI), and a
high performance Dual/Quad output as well as Dual/Quad I/O SPI: Serial Clock (CLK), Chip Select (CS#),
Serial Data I/O0 (SI), I/O1 (SO), I/O2 (WP#), and I/O3 (HOLD#). SPI clock frequencies of up to 104 MHz are
supported allowing equivalent clock rates of 208 MHz (104 MHz x 2) for Dual I/O and 416 MHz (104 MHz x 4)
for Quad I/O when using the Fast Read Dual/Quad I/O instructions. These transfer rates can outperform
standard Asynchronous 8 and 16-bit Parallel Flash memories. The Continuous Read Mode allows for efficient
memory access with as few as 8-clocks of instruction-overhead to read a 24-bit address, allowing true XIP
(execute in place) operation.
A Hold pin, Write Protect pin and programmable write protection, with top or bottom array control, provide
further control flexibility. Additionally, the device supports JEDEC standard manufacturer and device
identification with a 64-bit Unique Serial Number.
S25FL004K
The S25FL004K array is organized into 2,048 programmable pages of 256 bytes each. Up to 256 bytes can
be programmed at a time. Pages can be erased in groups of 16 (4-kB sector erase), groups of 128 (32-kB
block erase), groups of 256 (64-kB block erase) or the entire chip (chip erase). The S25FL004K has 128
erasable sectors and 8 erasable blocks respectively. The small 4-kB sectors allow for greater flexibility in
applications that require data and parameter storage.
S25FL008K
The S25FL008K array is organized into 4,096 programmable pages of 256 bytes each. Up to 256 bytes can
be programmed at a time. Pages can be erased in groups of 16 (4-kB sector erase), groups of 128 (32-kB
block erase), groups of 256 (64-kB block erase) or the entire chip (chip erase). The S25FL008K has 256
erasable sectors and 16 erasable blocks respectively. The small 4-kB sectors allow for greater flexibility in
applications that require data and parameter storage.
S25FL016K
The S25FL016K array is organized into 8,192 programmable pages of 256 bytes each. Up to 256 bytes can
be programmed at a time. Pages can be erased in groups of 16 (4-kB sector erase), groups of 128 (32-kB
block erase), groups of 256 (64-kB block erase) or the entire chip (chip erase). The S25FL016K has 512
erasable sectors and 32 erasable blocks respectively. The small 4-kB sectors allow for greater flexibility in
applications that require data and parameter storage.
