1 General Description
The AS8202NF communication controller is an
integrated device supporting serial communication
according to the TTP specification version 1.1. It
performs all communication tasks such as reception and
transmission of messages in a TTP cluster without
interaction of the host CPU. TTP provides mechanisms
that allow the deployment in high-dependability
distributed real-time systems. It provides the following
services:
Predictable transmission of messages with minimal
jitter
Fault-tolerant distributed clock synchronization
Consistent membership service with small delay
Masking of single faults
40 MHz main clock with support for 10 MHz crystal,
10 MHz oscillator or 40 MHz oscillator
16 MHz bus guardian clock with support for 16 MHz
crystal or 16 MHz oscillator
Single power supply 3.3V, 0.35µm CMOS process
Full automotive temperature range (-40ºC to 125ºC)
16k x 16 SRAM for message, status, control area
(communication network interface) and for
scheduling information (MEDL)
4k x 16 (plus parity) instruction code RAM for
protocol execution code
Data sheet conforms to protocol revision 2.04
16k x 16 instruction code ROM containing startup
execution code and deprecated protocol code
revision 1.00
16 Bit non-multiplexed asynchronous host CPU

Certification support package according to RTCA/
DO-254 DAL A available (www.tttech.com)
80 pin LQFP80 Package
2 Key Features
Dual-channel controller for redundant data transfers
Dedicated controller supporting TTP (time-triggered
protocol class C)
Suited for dependable distributed real-time systems
with guaranteed response time
Asynchronous data rate up to 5 Mbit/s (MFM/
Manchester)
Synchronous data rate 5 to 25 Mbit/s
Bus interface (speed, encoding) for each channel
selectable independently
