概要

Description

ATSAMG55J19B-MUT is an Atmel/Microchip 32‑bit microcontroller in the SAM G55 family. It uses an ARM Cortex‑M4F core, runs up to about 120 MHz, and includes a floating‑point unit and DSP instructions for efficient signal processing.
Key points:
- On‑chip memory and package vary by variant; typical G55 devices have hundreds of kilobytes of flash and tens of kilobytes of RAM. Check the datasheet for exact figures for this part.
- Peripherals usually include USB OTG FS, CAN 2.0B, USART/UART, SPI, I2C, PWM/timers, and a 12‑bit ADC, plus an event system and GPIOs.
- Power options cover several modes (Active, Idle, Sleep, Standby) for mixed‑signal and low‑power designs.
- Common applications: motor control, power electronics, industrial, and IoT.
- Development: MPLAB X with Harmony/ASF or Atmel Studio with GCC toolchains; use the product page/datasheet for package options and exact specs.
- Note: The -MUT suffix indicates packaging/power/temperature options; verify exact specifications on the official datasheet.

Features

Key features of ATSAMG55J19B-MUT (typical for this family):
- 32-bit ARM Cortex-M4F core with DSP and floating-point unit
- Up to around 120 MHz operation
- On-chip Flash and RAM (size varies by device/package)
- Peripherals: USB 2.0 (device/OTG depending on variant), CAN, I2C, SPI, UART/USART, I2S
- Analog: multiple 12-bit ADCs; DAC available on some variants
