Datasheet
1. Introduction
The development board for the Atmel
ATA6625-EK) is designed to give designers a quick start with these ICs and for the
prototyping and testing of new LIN designs.
The Atmel ATA6620 and the Atmel ATA6625 are fully integrated LIN transceivers
including a low-drop voltage regulator providing 5V/85mA. The only difference
between the two parts is the improved EMC behavior of the Atmel ATA6625. The
Atmel ATA6623 is pin and function compatible with the Atmel ATA6620/25, but on the
Atmel ATA6623 the voltage at the regulator’s output is 3.3V instead of 5V. The combi-
nation of LIN transceiver and voltage regulator makes it possible to develop simple,
powerful, and cheap slave nodes in LIN bus systems.
The ICs are designed to handle the low-speed data communication in vehicles, for
example in convenience electronics. Improved slope control at the LIN-driver ensures
secure data communication up to 20Kbaud.
Besides normal mode there are two other modes, sleep mode and silent mode, which
give the designer the opportunity to create modules which meet the different require-
ments of the application with respect to low current consumption.
This document has been developed to give the user a quick start using the develop-
ment board for the Atmel ATA6620/23/25. For more detailed information about the
devices themselves, refer to the corresponding datasheets.

... LIN slave node immediately. Connecting an external 12V DC power supply with the terminals VBAT and GND puts the Atmel ATA6620/23/25 in pre-normal mode, where a 5V (3.3V) DC voltage provided by the internal voltage regulator can be measured between VCC and GND. In addition, the following voltages can be measured at the pins RXD and LIN: Table 1-1 ...
