HS I2C-Compatible Module
General Description
The HS I2CTM-compatible module is a reference solution for implementing an interface that is compatible with the high-speed (HS) mode (3.4MHz, 1.7MHz), fast mode (400kHz), and standard mode (100kHz) of the I2C standard. The module consists primarily of an Altera EPM3256AQC208-10 programmable logic device (PLD) containing the DI2CM core available from Digital Core Design. The module allows microcontrollers (Cs) with a compatible 8-bit-memory-mapped parallel interface to communicate with I2C-compatible slave devices. The HS I2C-compatible module is provided as part of selected Maxim evaluation systems. The main purpose of the HS I2C-compatible module is the evaluation of Maxim products. The use of the HS I 2C-compatible module as a development board or any other use not described in selected Maxim evaluation kit (EV kit)/ evaluation system (EV system) data sheets is not supported by Maxim.

Description of Hardware
HS I2C-Compatible Module Supplies
The HS 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 C module normally provides both of these supplies. I2C-compatible
