1 Product Description
The TPMC816 is a standard single-width 32 bit PMC module with two complete CAN bus interfaces
using two Innovasic Semiconductor IA82527 CAN controllers. The IA82527 is a form, fit and function
replacement for the Intel 82527 CAN controller. Both channels are completely independent and
support CAN specification 2.0 part A and B (Standard 11 bit identifier and extended 29 bit identifier).
Each channel provides CAN High Speed and modified RS485 as physical interface. The physical
interfaces are optically isolated from the CAN controller and powered by an on board DC/DC converter
for each channel. The TPMC816-11 provides one CAN bus channel.
