System Block Diagram

The system block diagram for a stand alone reader application is shown in Figure 1-1. No

additional microcontroller is required..

Figure 1-1.

System Block Diagram - Stand Alone Reader

A system block diagram for a reader station application with a LIN transceiver IC is shown in

Figure 1-2. The reader is then communicating with a central unit.

Block Diagram

In Figure 1-3 on page 5 the basic architecture of the Atmel ATA5505 consisting of the Atmel

AVR and the front end is shown. The Atmel AVR is a low-power CMOS 8-bit microcontroller

with RISC architecture. The Atmel AVR includes several features. The main features are

in-system programmable Flash, EEPROM, SRAM, Ports A and B as general purpose I/O

lines, a timer and a LIN controller. The details of the front end are shown in Figure 1-4 on page
