HS I2C-Compatible Module
General Description
Features
ꢀ HS-Mode I2C-Compatible Interface (3.4MHz, 1.7MHz)
ꢀ Fast-Mode I2C-Compatible Interface (400kHz)
ꢀ Standard-Mode I2C-Compatible Interface (100kHz)
ꢀ Proven Design
The HS I2C™-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 stan-
dard. 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 (µCs) with a
compatible 8-bit-memory-mapped parallel interface to
communicate with I2C-compatible slave devices.
ꢀ Proven PC Board Layout
ꢀ On-Board 40MHz Crystal Oscillator
ꢀ On-Board Regulated +3.3V
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 I2C-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 sup-
ported by Maxim.
