Data Sheet  
AS8202NF  
TTP-C2NF Communication Controller  
40 MHz main clock with support for 10 MHz crystal,  
10 MHz oscillator or 40 MHz oscillator  
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:  
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  
Predictable transmission of messages with minimal  
jitter  
Data sheet conforms to protocol revision 2.04  
Fault-tolerant distributed clock synchronization  
Consistent membership service with small delay  
Masking of single faults  
16k x 16 instruction code ROM containing startup  
execution code and deprecated protocol code  
revision 1.00  
16 Bit non-multiplexed asynchronous host CPU  
interface  
2 Key Features  
Dual-channel controller for redundant data transfers  
16 Bit RISC architecture  
Software tools, design support, development boards  
available (www.tttech.com)  
Dedicated controller supporting TTP (time-triggered  
Certification support package according to RTCA/  
DO-254 DAL A available (www.tttech.com)  
protocol class C)  
Suited for dependable distributed real-time systems  
80 pin LQFP80 Package  
with guaranteed response time  
Asynchronous data rate up to 5 Mbit/s (MFM/  
Manchester)  
3 Applications  
Application fields: automotive (by-wire braking, steering,  
vehicle dynamics control, drive train control), aerospace  
(aircraft electronic systems), industrial systems, railway  
systems.  
Synchronous data rate 5 to 25 Mbit/s  
Bus interface (speed, encoding) for each channel  
selectable independently
