Description
The AT93C46D provides 1,024 bits of serial electrically erasable programmable
read only memory (EEPROM) organized as 64 words of 16 bits each, when the
ORG pin is connected to VCC and 128 words of 8 bits each when it is tied to
ground. The device is optimized for use in many automotive applications where
low power and low voltage operations are essential. The AT93C46D is available
in space-saving 8-lead TSSOP and 8-lead JEDEC SOIC packages. The
AT93C46D 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 (SK). 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 it is in the Erase/Write Enable state. When CS is
brought “high” following the initiation of a write cycle, the DO pin outputs the
Ready/Busy status.

Functional Description
The AT93C46D is accessed via a simple and versatile 3-wire serial communication interface. The device
operation is controlled by seven instructions issued by the host processor. A valid instruction starts with a rising
edge of CS and consists of a Start bit (Logic 1) followed by the appropriate Opcode and the desired memory
Address location.
READ: The 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
(DO) pin. Output data changes are synchronized with the rising edges of Serial Clock (SK).
Note: A dummy bit (Logic 0) precedes the 8- or 16-bit data output string.

ERASE/WRITE (EWEN): To assure data integrity, the part automatically goes into the Erase/Write Disable
(EWDS) state when the power is first applied. An EWEN instruction must be executed first before any
programming instructions can be carried out.
Note: Once in the EWEN state, programming remains enabled until an EWDS instruction is executed or VCC
power is removed from the part.

ERASE: The Erase instruction programs all of the bits in the specified memory location to the Logic 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 250ns (tCS). A Logic 1
at the DO pin indicates that the selected memory location has been erased, and the part is ready for another
instruction.

WRITE: The 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
250ns (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
.

Erase All (ERAL): The 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 250ns (tCS). The ERAL instruction is valid only at
VCC = 5.0V 10%.

ERASE/WRITE DISABLE (EWDS): To protect against accidental data disturb, the EWDS instruction disables
