Atmel recently announced its next-generation family of automotive-qualified ARM Cortext-M0+-based micrcontrollers with an integrated peripheral touch controller (PTC) for capacitive touch applications. The new SAM DA1 is the first series in this Atmel |SMART MCU automotive-qualified product family, operating at a maximum frequency of 48 MHz and reaching a 2.14 Coremark/MHz.
Atmel’s SAM DA1 series is ideal for capacitive touch button, slider, wheel or proximity sensing applications and offers high analog performance for greater front-end flexibility. The new devices are available down to a very compact QFN 5 × 5 mm package with wettable flanks for automated optical inspection.
Eliminating external components and offering more robust features, devices in the SAM DA1 series come with 32 to 64 pins, up to 64 KB of flash memory, 8 KB of SRAM, and 2-KB read-while-write flash memory and are qualified according to the AEC Q-100 Grade 2 (–40° to 105°C).
