Description of Hardware
HS I2C-Compatible Module Supplies
The HS I2C-compatible module requires two supplies.
The on-board 3.3V regulator requires an input voltage at
VIN of 4.5V to 24V (J3-5, J3-6). The module also requires
a regulated 5V logic supply (J3-7, J3-8). A Maxim µC
module normally provides both of these supplies.
EPM3256AQC208-10 PLD (Altera)
The EPM3256AQC208-10 is from Altera’s MAX3000A
family of PLDs. This 256 product-term device accepts
3.3V or 5V logic even when powered from a 3.3V sup-
ply. Contact Altera for any questions relating to the
PLD. See the Component Suppliers section for contact
information.
