Atmel® Corporation (Nasdaq: ATML) announced the availability of its ATA6623 and ATA6625 LIN system basis chips (SBCs), which are designed in compliance with the LIN 2.0 specification and the SAEJ2602 standard. The new devices incorporate Atmel’s 2nd generation LIN transceiver that provides the industry’s best EMC performance and has obtained approval from major OEMs worldwide. Thanks to Atmel’s high-voltage BCD-on-SOI technology SMARTIS(TM) and the SO8 power package, the devices can operate at supply voltages up to 40V. Applications include automotive comfort applications such as door modules, seat control or intelligent sensors, and powertrain applications.
As with all Atmel LIN ICs, the new ATA6623 and ATA6625 provide excellent ESD stability. They have an ESD stability of greater than 6 kV, which is actually the standard for modules with external components.
The new LIN devices are highly integrated. In addition to the LIN transceiver, they also incorporate a low-drop voltage regulator (ATA6623: 3.3V output voltage, ATA6625: 5V output voltage). As a result, system costs can be reduced by approximately 20%. Less board space is needed, which makes these devices ideally suited for applications requiring very small footprints. The SMARTIS process uses SOI (silicon-on-insulator) substrate, which results in an extremely low leakage current and a significant reduction in crosstalk between the analog and digital circuits on the same die as well as latch-up-free operation at high temperatures. The use of SOI also results in lower parasitic effects, which improves EMC performance.
The ATA6623 and ATA6625 offer several protective features such as overtemperature shutdown and full protection against short circuits. The ATA6623/25 also meet strict automotive qualification demands and can withstand transients according to ISO/TR 7637/1.
Availability and Pricing
ATA6623 and ATA6625 samples are now available in lead-free SO8 packages with pricing starting at US $0.89 each for 10k piece quantities.
