ATSAMG55G19A-UUT

ARM微控制器 - MCU WLCSP, IND TEMP T&R

Description ATSAMG55G19A-UUT

The ATSAMG55G19A-UUT Atmel® | SMART SAM G55 is a series of Flash microcontrollers based on the high-performance 32-bit ARM® Cortex®-M4 RISC processor with FPU (Floating Point Unit). It operates at a maximum speed of 120 MHz and features 512 Kbytes of Flash and up to 176 Kbytes of SRAM. The peripheral set includes eight flexible communication units comprising USARTs, SPIs and I2C-bus interfaces (TWIs), two three-channel general-purpose 16-bit timers, two I2 S controllers, one-channel pulse density modulation, one 8-channel 12-bit ADC, one real-time timer (RTT) and one real-time clock (RTC), both located in the ultra low-power backup area.
