Microchip ATSAMG55J19A-MU

ARM® Cortex®-M4120MHz512KB（512K x 8）

Overview

The ATSAMG55J19A-MU is a SMART SAM G55 series 32-bit Flash Microcontroller based on the high-performance ARM Cortex-M4 RISC processor with floating point unit (FPU). It operates at a maximum speed of 120MHz and features 512kB of flash and up to 176kB 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 I²S controllers, one-channel pulse density modulation, one 8-channel 12-bit ADC, one real-time timer (RTT) and one real-time clock (RTC). The SMART SAM G55 devices have three software-selectable low-power modes, sleep, wait and backup. In sleep mode, the processor is stopped while all other functions can be kept running. In wait mode, all clocks and functions are stopped but some peripherals can be configured to wake up the system based on events, including partial asynchronous wake-up (SleepWalking™). In backup mode, RTT, RTC and wakeup logic are running.
