Description:
The Microchip Technology Inc. 93XX86A/B/C devices
are 16K bit low-voltage serial Electrically Erasable
PROMs (EEPROM). Word-selectable devices such as
the 93XX86C are dependent upon external logic
levels driving the ORG pin to set word size. In the
SOT-23 package, the 93XX86A devices provide
dedicated 8-bit memory organization, while the
93XX86B devices provide dedicated 16-bit memory
organization. A Program Enable (PE) pin allows the
user to write-protect the entire memory array.
Advanced CMOS technology makes these devices
ideal for low-power, nonvolatile memory applications.
The entire 93XX Series is available in standard
packages including 8-lead PDIP and SOIC, and
advanced packaging including 8-lead MSOP, 6-lead
SOT-23, 8-lead 2x3 DFN and 8-lead TSSOP. Pb-free
(Pure Matte Sn) finish is available.

2.4 Erase
The ERASE instruction forces all data bits of the
specified address to the logical ‘1’ state. The rising
edge of CLK before the last address bit initiates the
write cycle.
The DO pin indicates the Ready/Busy status of the
device if CS is brought high after a minimum of 250 ns
low (TCSL). DO at logical ‘0’ indicates that programming
is still in progress. DO at logical ‘1’ indicates that the
register at the specified address has been erased and
the device is ready for another instruction.
Note:
After the Erase cycle is complete, issuing
a Start bit and then taking CS low will clear
the Ready/Busy status from DO.
