Microchip introduces first automotive-grade LIN SiP with touch hardware support

Microchip Technology Inc., a provider of microcontroller, mixed-signal, analog and Flash-IP solutions, has introduced the first automotive-grade Local Interconnect Network (LIN) System-in-Package (SiP) solution including a microcontroller with integrated touch hardware support. LiN systems are used throughout the automobile in comfort, powertrain, sensor, and actuator applications.

The SAMHA1GxxA microcontroller family contains capacitive touch hardware support, an event system and complex PWM capability. The series is suited 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 7 × 7 mm QFN package, with wettable flanks ready for automatic optical solder inspection and is available with 16k, 32k or 64k Flash memory, up to 8 KB SRAM and 2 KB Read-While-Write Flash.

The microcontroller family is automotive-grade and designed to meet the high quality standards of the automotive industry. It features easy-to-create touch buttons with high sensitivity and outstanding noise immunity, supported by the QTouch software function library. The high electromagnetic compatibility (EMC) robustness of the LIN communication fulfills the requirements of OEMs worldwide.

To accelerate development for customers, Microchip is providing the SAMHA1G16X-XPRO development kit, which includes support from Atmel Software Framework (ASF). The SAMHA1GxxA device is implemented in the Atmel Studio 7 Integrated Development Environment. Various tools such as GCC and IAR C/C++ compilers, ICE debuggers and a QTouch software function library are also available.

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