Automotive-grade LIN SiP includes touch support
Claimed to be the industry’s first automotive-grade LIN System in Package (SiP) with integrated touch hardware support, the SAMHA1GxxA microcontroller family is by Microchip. It contains capacitive touch hardware support, an event system and complex PWM capability and is designed for touch button, touchpad, slider, wheel or proximity sensing applications, including optical and haptic feedback.
The SAMHA1GxxA contains an ARM Cotex-M0+ microcontroller (MCU), a LIN transceiver based on Microchip’s fourth-generation LIN IP, and a voltage regulator. It is offered in a 7.0 x 7.0mm QFN package, with wettable flanks ready for automatic optical solder inspection. It is available with 16, 32 or 64k flash memory, up to 8kbyte SRAM and 2kbyte read-while-write flash.
The MCU family is automotive-grade and features easy-to-create touch buttons with high sensitivity and outstanding noise immunity, says the company, supported by its QTouch software function library.
The SAMHA1G16X-XPRO development kit includes support from Atmel Software Framework (ASF). The SAMHA1GxxA device is implemented in the Atmel Studio 7 IDE. Tools such as GCC and IAR C/C++ compilers, ICE debuggers and a QTouch software function library are also available.
