The SAM DA1 ARM® Cortex™-M0+ -based microcontrollers are operating at 48MHz (45DMIPS). The ATSAMDA1G14A provides 16KB Flash, 4kB SRAM and 512Byte RWW Flash. The connectivity peripheral set consists of 6 serial communication modules (SERCOM) that each can be configured to act as a USART, UART, SPI and I2C. Additional connectivity options are provided by the on-chip one channel Inter-IC sound interface (I2S) and the full-speed USB 2.0 embedded host and device.

Hardware touch support is provided by the embedded Peripheral Touch Controller (PTC) enabling for high-sensitivity, environmentally robust capacitive touch solutions by auto calibration/compensation and hardware noise filtering.

A 12-bit ADC with 14 channels and 350ksps with programmable gain is included as well as one 10-bit 350ksps DAC and two analog comparators with window mode. SAM DA1 features five 16bit Timer/Counter Modules and 3 TCC (Timer Counter for Control). ATSAMDA1G14A is AEC-Q100 grade2 qualified (-40 to 105°C) and is packaged in TQFP48 or in QFN48.

关键特性

  • High analogue performance— 12-bit 350ksps analog-to-digital converter (ADC) with 14 channels, programmable gain stage, automatic offset and gain error compensation, oversampling and decimation in hardware to support up to 16-bit resolution 10-bit, 350ksps digital-to-analog converter (DAC), two analog comparators (AC) with window compare function
  • Excellent real-time behavior — 12 channel Event-System, Single-Cycle IO access
  • Low-Power Optimizations — Idle and standby sleep modes, SleepWalking peripherals and versatile clocking schemes
  • Comprehensive peripheral set for connectivity — Six serial communication interfaces (SERCOM), each configurable to operate as either USART, UART, I2C up to 3.4MHz or SPI plus USB 2.0 Full-Speed embedded host and device and one channel Inter-IC sound interface (I2S)
  • State-of-the-art Touch Support— Peripheral Touch Controller supporting capacitive buttons, sliders, wheels and proximity sensing. Up to 120 channels in mutual mode and 10 channels in self-capacitance mode are supported
