Microchip Technology has introduced an automotive-grade local interconnect network (LIN) system-in-package (SiP) solution, which includes a microcontroller with integrated touch hardware support.

The SAMHA1GxxA microcontroller family contains capacitive touch hardware support, an event system and complex PWM capability. The series is ideal for touch button, touchpad, slider, wheel or proximity sensing applications, including optical and haptic feedback.

The SAMHA1GxxA contains an ARM Cortex-M0+ microcontroller (MCU), a LIN transceiver based on Microchip's fourth-generation LIN IP and a voltage regulator. The system solution comes in a 7mm × 7mm QFN package, with wettable flanks ready for automatic optical solder inspection and is available with 16k, 32k or 64k Flash memory, up to 8KB SRAM and 2kB Read-While-Write Flash.

The microcontroller family is designed to meet the high quality standards of the automotive industry, according to Microchip. It features easy-to-create touch buttons with high sensitivity and noise immunity, supported by the company's QTouch software function library.

SAMHA1GxxA is available in volume production with prices starting at $2.88.
