Description
The Microchip Technology Inc. 93XX76A/B/C devices
are 8K bit, low-voltage, serial Electrically Erasable
PROMs (EEPROM). Word-selectable devices such as
the 93XX76C are dependent upon external logic
levels driving the ORG pin to set word size. For
dedicated 8-bit communication, the 93XX76A devices
are available, while the 93XX76B devices provide
dedicated 16-bit communication, available on SOT-23
devices only. 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 93XX Series is available in standard packages
including 8-lead PDIP and SOIC, and advanced
packaging including 8-lead MSOP, 6-lead SOT-23,
and 8-lead TSSOP. Pb-free (Pure Matte Sn) finish is
also 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:
Issuing a Start bit and then taking CS low
will clear the READY/BUSY status from
DO.
