Description
The AT93C86A provides 16,384 bits of Serial Electrically Erasable Programmable
Read-Only Memory (EEPROM), organized as 1,024 words of 16 bits each when
the ORG pin is connected to VCC and 2,048 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 AT93C86A is available
in space saving 8-lead JEDEC SOIC and 8-lead TSSOP packages.
The AT93C86A 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 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 AT93C86A is available in a 2.7V to 5.5V
version.
