Description:
The Microchip Technology Inc. 11AAXXX/11LCXXX
(11XX
*
) devices are a family of 1 Kbit through 16 Kbit
Serial Electrically Erasable PROMs. The devices are
organized in blocks of x8-bit memory and support the
patented** single I/O UNI/O
®
serial bus. By using
Manchester encoding techniques, the clock and data
are combined into a single, serial bit stream (SCIO),
where the clock signal is extracted by the receiver to
correctly decode the timing and value of each bit.
Low-voltage design permits operation down to 1.8V (for
11AAXXX devices), with standby and active currents of
only 1 uA and 1 mA, respectively.
The 11XX family is available in standard packages
including 8-lead PDIP and SOIC, and advanced
packaging including 3-lead SOT-23, 8-lead TDFN,
and 8-lead MSOP.
