General Description
4
The S25FL064K (16-Mbit) Serial Flash memory provides an ideal storage solution for systems with limited
space, pins and power. The device offers flexibility and performance well beyond ordinary Serial Flash
devices. It is ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing
voice, text and data. The device operates 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 S25FL064K array is organized into 32,768 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 S25FL064K has
2048 erasable sectors and 128 erasable blocks respectively. The small 4 KB sectors allow for greater
flexibility in applications that require data and parameter storage.
The S25FL064K supports 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 80 MHz are supported allowing equivalent
clock rates of 160 MHz (80 MHz x 2) for Dual I/O and 320 MHz (80 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.
