Description
The Atmel
®
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 V
CC
) 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 applications where low-power and low-voltage operations are
essential. The AT93C46D is available in space-saving 8-lead JEDEC SOIC,
8-lead TSSOP, 8-pad UDFN, 8-lead PDIP, and 8-ball VFBGA 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 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 AT93C46D operates from 1.8V to 5.5V.
