DESCRIPTION
The FT93C46/56/66 series are 1024/2048/4096 bits of serial Electrical Erasable and Programmable
Read Only Memory, commonly known as EEPROM. They are organized as 64/128/256 words of 16 bits
each when the ORG pin is connected to VCC (or unconnected) and 128/256/512 words of 8 bits (1 byte)
each when the ORG pin is tied to ground. 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 JEDEC SOP, 8-lead TSSOP and 8-lead DFN packages. Our extended VCC range (1.8V to
5.5V) devices enables wide spectrum of applications.
The FT93C46/56/66 is enabled through the Chip Select pin (CS), and accessed via a 3-wire serial
interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SCL). Upon receiving a READ
instruction at DI, the address is decoded and the data is clocked out serially on the data output pin DO.
The WRITE cycle is completely self-timed and no separate ERASE cycle is required before WRITE. The
WRITE cycle is only enabled when the part is in the ERASE/WRITE ENABLE state. Once a device
begins its self-timed program procedure, the data out pin (DO) can indicate the READY/BUSY status by
rising chip select (CS).

(D) SERIAL DATA OUTPUT (DO)
This is data output signal for the serial device.
(E) INTERNAL ORGANIZATION (ORG)
This is internal organization input signal for the serial EEPROM device. When the ORG pin is
connected to VCC or unconnected the EEPROM is organized as 64/128/256 word of 16 bits each and

MEMORY ORGANIZATION
The FT93C46/56/66 memory is organized either as bytes (x8) or as words (x16). If Internal Organization
(ORG) is unconnected (or connected to VCC) the words (x16) organization is selected; When Internal
Organization is connected to ground the bytes (x8) organization is selected.

INSTRUCTION SETS DESCRIPTION
(A) READ
The Read (READ) instruction contains the Address code for the memory location to be read. After the
instruction and address are decoded, data from the selected memory location is available at the serial
output pin DO. Output data changes are synchronized with the rising edges of serial clock SK. It
should be noted that when a dummy bit (logic “0”) precedes the 8- or 16-bit data output string.
(B) ERASE/WRITE ENABLE
To assure data integrity, the part automatically goes into the Erase/Write Disable (EWDS) state when
power is first applied. An Erase/Write Enable (EWEN) instruction must be executed first before any
programming instructions can be carried out. Please note that once in the Erase/Write Enable state,
programming remains enabled until an Erase/Write Disable (EWDS) instruction is executed or VCC
power is removed from the part.
(C) ERASE/WRITE DISABLE
To protect against accidental data disturb, the Erase/Write Disable (EWDS) instruction disables all
programming modes and should be executed after all programming operations. The operation of the
READ instruction is independent of both the EWEN and EWDS instructions and can be executed at
any time.
(D) ERASE
The Erase (ERASE) instruction programs all bits in the specified memory location to the logical “1”
state. The self-timed erase cycle starts once the ERASE instruction and address are decoded. The
DO pin outputs the READY/BUSY status of the part if CS is brought high after being kept low for a
minimum of 250 ns (tCS). A logic “1” at pin DO indicates that the selected memory location has been
erased, and the part is ready for another instruction.
(E) WRITE
The Write (WRITE) instruction contains the 8 or 16 bits of data to be written into the specified memory
location. The self-timed programming cycle, tWP, starts after the last bit of data is received at serial
data input pin DI. The DO pin outputs the READY/BUSY status of the part if CS is brought high after
being kept low for a minimum of 250 ns (tCS). A logic “0” at DO indicates that programming is still in
progress. A logic “1” indicates that the memory location at the specified address has been written with
the data pattern contained in the instruction and the part is ready for further instructions. A
READY/BUSY status cannot be obtained if the CS is brought high after the end of the self-timed
programming cycle, tWP.
(F) ERASE ALL
The Erase All (ERAL) instruction programs every bit in the memory array to the logic “1” state and is
primarily used for testing purposes. The DO pin outputs the READY/BUSY status of the part if CS is
brought high after being kept low for a minimum of 250 ns (tCS). The ERAL instruction is valid only at
VCC = 5.0V ± 10%.
(G) WRITE ALL
The Write All (WRAL) instruction programs all memory locations with the data patterns specified in the
instruction. The DO pin outputs the READY/BUSY status of the part if CS is brought high after being
kept low for a minimum of 250 ns (tCS). The WRAL instruction is valid only at VCC = 5.0V ± 10%.
