Description

The AT93C46D provides 1024 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 the ORG pin is tied to

ground). The device is optimized for use in many industrial and commercial applica-

tions where low-power and low-voltage operations are essential. The AT93C46D is

available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Thin mini-

MAP (MLP 2x3), 8-lead TSSOP, and 8-lead dBGA2 packages.

AT93C46D

The AT93C46D 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 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.

Preliminary

The AT93C46D is available in 1.8 (1.8V to 5.5V) version.
