SUMMARY DESCRIPTION
The M25P32 is a 32Mbit (4M x 8) Serial Flash Memory, with advanced write protection mechanisms,
accessed by a high speed SPI-compatible bus.
The memory can be programmed 1 to 256 bytes at a time, using the Page Program instruction.
The memory is organized as 64 sectors, each containing 256 pages. Each page is 256 bytes wide.
Thus, the whole memory can be viewed as consisting of 16384 pages, or 4,194,304 bytes.
The whole memory can be erased using the Bulk Erase instruction, or a sector at a time, using the
Sector Erase instruction.

SIGNAL DESCRIPTION
Serial Data Output (Q). This output signal is used to transfer data serially out of the device.
Data is shifted out on the falling edge of Serial Clock (C). Serial Data Input (D). This input signal 

is used to transfer data serially into the device. It receives instructions, addresses, and the data to 

be programmed. Values are latched on the rising edge of Serial Clock (C). Serial Clock (C). This 

input signal provides the timing of the serial interface. Instructions, addresses, or data present 

at Serial Data Input (D) are latched on the rising edge of Serial Clock (C). Data on Serial Data Output (Q) 

changes after the falling edge of Serial Clock (C). Chip Select (S). When this input signal is High, 

the device is deselected and Serial Data Output (Q) is at high impedance. Unless an internal Program,
Erase or Write Status Register cycle is in progress, the device will be in the Standby Power
mode (this is not the Deep Power-down mode). Driving Chip Select (S) Low enables the device,
placing it in the Active Power mode. After Power-up, a falling edge on Chip Select (S)
is required prior to the start of any instruction. Hold (HOLD). The Hold (HOLD) signal is used to
pause any serial communications with the device without deselecting the device.
During the Hold condition, the Serial Data Output (Q) is high impedance, and Serial Data Input (D)
and Serial Clock (C) are Don’t Care. To start the Hold condition, the device must be selected,
with Chip Select (S) driven Low. Write Protect (W). The main purpose of this input
signal is to freeze the size of the area of memory that is protected against program or erase
instructions (as specified by the values in the BP2, BP1 and BP0 bits of the Status Register).
