Description:
The Microchip Technology Inc. 93XX66A/B/C devices
are 4Kbit low-voltage serial Electrically Erasable
PROMs (EEPROM). Word-selectable devices such as
the 93AA66C, 93LC66C or 93C66C are dependent
upon external logic levels driving the ORG pin to set
word size. For dedicated 8-bit communication, the
93XX66A devices are available, while the 93XX66B
devices provide dedicated 16-bit communication.
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. All
packages are Pb-free (Matte Tin) finish.
