1. Features
2. Description
The AT93C46E provides 1024 bits of serial electrically-erasable programmable read-
only memory (EEPROM) organized as 64 words of 16 bits each. The device is opti-
mized for use in many industrial and commercial applications where low-power and
low-voltage operation are essential. The AT93C46E is available in space-saving 8-
lead PDIP, 8-lead JEDEC SOIC, and 8-lead TSSOP packages.
The AT93C46E is enabled through the Chip Select pin (CS) and accessed via a three-
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 DO pin. 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. When CS is brought high following the
initiation of a write cycle, the DO pin outputs the ready/busy status of the part.
The AT93C46E is available in 1.8V (1.8V to 5.5V) version.

... This parameter is ensured by characterization. 3. Functional Description The AT93C46E is accessed via a simple and versatile three-wire serial communication inter- face. 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 op code and the desired memory address location ...

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 a dummy bit (logic “ ...

... ERASE/WRITE DISABLE (EWDS): 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. AT93C46E 6 5207D–SEEPR–1/08 ...
