GENERAL DESCRIPTION
The F25L08PA is a 8Megabit, 3V only CMOS Serial Flash
memory device organized as 1M bytes of 8 bits. The device
supports the standard Serial Peripheral Interface (SPI), and a
Dual SPI. ESMT’s memory devices reliably store memory data
even after 100,000 programming and erase cycles.
The memory array can be organized into 4,096 programmable
pages of 256 byte each. 1 to 256 byte can be programmed at a
time with the Page Program instruction. The device also can be
programmed to decrease total chip programming time with Auto
Address Increment (AAI) programming.
The device features sector erase architecture. The memory array
is divided into 256 uniform sectors with 4K byte each; 16 uniform
blocks with 64K byte each. Sectors can be erased individually
without affecting the data in other sectors. Blocks can be erased
individually without affecting the data in other blocks. Whole chip
erase capabilities provide the flexibility to revise the data in the
device. The device has Sector, Block or Chip Erase but no page
erase.
The sector protect/unprotect feature disables both program and
erase operations in any combination of the sectors of the
memory.

To transfer commands, addresses or data
serially into the device.
Data is latched on the rising edge of SCK.
To transfer data serially out of the device.
Data is shifted out on the falling edge of
SCK.
To activate the device when CE is low.
The Write Protect (

STATUS REGISTER
The software status register provides status on whether the flash
memory array is available for any Read or Write operation,
whether the device is Write enabled, and the state of the memory
Write protection. During an internal Erase or Program operation,
the status register may be read only to determine the completion
of an operation in progress. Table 2 describes the function of
each bit in the software status register.
