DESCRIPTION
The FT25C08A is 8192 bits of serial Electrical Erasable and Programmable Read Only Memory, commonly
known as EEPROM. They are organized as 1024 words of 8 bits (1 byte) each. The devices are fabricated
with proprietary advanced CMOS process for low power and low voltage applications. These devices are
available in standard 8-lead DIP, 8-lead SOP and 8-lead TSSOP packages. The memory is accessed via a
simple Serial Peripheral Interface (SPI) compatible serial bus. The HOLD pin may be used to suspend
any serial communication without resetting the serial sequence. While the device is paused, transitions on
its inputs will be ignored. Our extended VCC range (1.8V to 5.5V) devices enables wide spectrum of
applications.

DEVICE OPERATION
The FT25C08A utilizes an 8-bit instruction register. The list of instructions and their operation codes are
contained in Table A. All instructions, addresses, and data are transferred with the MSB first and start with a
high-to-low CS transition.

WRITE ENABLE (WREN): The device will power up in the write disable state when VCC is applied. All
programming instructions must therefore be preceded by a Write Enable instruction.
WRITE DISABLE (WRDI): To protect the device against inadvertent writes, the Write Disable instruction
disables all programming modes. The WRDI instruction is independent of the status of the WP pin.
READ STATUS REGISTER (RDSR): The Read Status Register instruction provides access to the status
register. The READY/BUSY and Write Enable status of the device can be determined by the RDSR
instruction. Similarly, the block write protection bits indicate the extent of protection employed. These bits
are set by using the WRSR instruction.
Table C Status Register Bit Definition
Bit Definition
Bit 0 ( RDY )
Bit 0 = “0” ( RDY ) indicates the device is READY. Bit 0 = “1”
indicates the write cycle is in progress.
Bit 1 (WEN)
Bit 2 (BP0)
Bit 1= “0” indicates the device is not WRITE ENABLED. Bit 1 = “1”
indicates the device is write enabled.
See table D.
Bit 3 (BP1)
See table D.
Bits 4-6 are “0”s when device is not in an internal write cycle.
Bit 7 (WPEN) See table E.
Bits 0-7 are “1” during an internal write cycle.
