What are the key features of ATA6612C-PLQW-1?
- Integrated LIN System Basis Chip (SBC) combines AVR 8-bit MCU and LIN 2.x transceiver in one 48-QFN 7×7 mm package, reducing ECU BOM by eliminating a discrete LIN transceiver IC
- AEC-Q100 automotive qualified for –40°C to +125°C operation with 16 MHz core clock (8 MHz at 2.7 V min supply) and 8 KB Flash for in-vehicle body control nodes
- On-chip ADC and extensive timer peripherals enable direct sensor acquisition and PWM motor/lamp control without additional analog front-end components
What is ATA6612C-PLQW-1 used for?
ATA6612C-PLQW-1 is designed for LIN-connected automotive body-control modules such as seat adjustment, door lock actuators, and interior lighting systems that require a low-cost, compact single-chip solution. Its integrated LIN transceiver eliminates the external transceiver IC, reducing ECU PCB area by up to 30% compared to a two-chip implementation. The 8-bit AVR core with 8 KB Flash also suits tire pressure monitoring sensor nodes and HVAC sub-controllers where LIN communication and local closed-loop control run on the same device.

Frequently Asked Questions
How does integrating the LIN SBC into ATA6612C-PLQW-1 reduce ECU component count versus a discrete MCU plus transceiver approach?
ATA6612C-PLQW-1 combines the 8-bit AVR core, 8 KB Flash, and a full LIN 2.x transceiver with voltage regulator into a single 48-QFN 7×7 mm package. A discrete approach requires a separate LIN transceiver IC (typically 8-pin SOIC), decoupling capacitors, and protection components, adding 10 to 15 extra parts. The integrated solution cuts BOM cost and reduces PCB area by approximately 30%, critical for door-module designs where space is at a premium.
At what supply voltage does ATA6612C-PLQW-1 reduce clock frequency, and what does this mean for a battery-backed automotive sensor node?
ATA6612C-PLQW-1 runs at up to 16 MHz when supplied at 4.5 V to 5.5 V and at up to 8 MHz when the supply drops to 2.7 V minimum. In a battery-backed sensor node where the 12 V automotive bus droops below 4.5 V during engine crank (typically 6 V to 9 V at the regulator output), the device continues operating at 8 MHz, maintaining LIN communication and sensor sampling without reset. This automatic frequency scaling avoids firmware complexity for brown-out handling.
Which automotive body control applications are best matched to ATA6612C-PLQW-1 given its 8 KB Flash and integrated LIN transceiver?
ATA6612C-PLQW-1 suits seat adjustment controllers, interior lighting dimmers, door lock actuators, and mirror adjustment modules where the LIN sub-node firmware typically occupies 4 KB to 6 KB of Flash. The on-chip ADC handles position sensor or current sense inputs directly, and the integrated LIN transceiver eliminates the external device required by a standalone ATmega328. AEC-Q100 qualification confirms suitability for –40°C to +125°C underhood and door cavity environments.
For a motor-control seat adjuster, how many PWM channels does ATA6612C-PLQW-1 provide and at what resolution?
ATA6612C-PLQW-1's AVR core includes multiple 8-bit and 16-bit timer/counter units, providing at least 6 PWM output channels at configurable frequencies. With a 16-bit timer at 16 MHz input clock, PWM resolution reaches 16 bits at frequencies down to about 244 Hz, or 8-bit resolution at up to 62.5 kHz, covering both slow seat-motor DC drive and faster solenoid actuation scenarios. This eliminates the need for a discrete PWM controller in a 3-motor seat module.
