Microchip's 32-bit MCUs

Microchip's 32-bit portfolio with the MIPS (microAptiv, M4K®, and M-class) and ARM® (Cortex® M0+, M4, M7) cores offer high performance microcontrollers, and all the tools needed to develop your embedded projects. 

With MPLAB® Harmony software framework, MPLAB Advanced Software Framework (ASF)* and low cost development tools, 32-bit MCUs shorten your time to market and allow your designs to scale

Leading Performance

PIC® 32-bit MCUs

  • PIC32MZ with up to 2MB Flash and 512KB SRAM offers the highest performance and highest integrations of peripherals in PIC series with 252MHz speed, CAN, Crypto, Ethernet, FPU and HS USB with 12-bit, 18 MSPS, up to 48 channel ADC module. Also AEC-Q100 Grade 1 Qualified
  • PIC32MX series offers a broad range of products with up to 120 MHz of performance,  from 16KB Flash and 4KB SRAM to 512KB Flash and 128KB SRAM, 10-bit ADC, CAN, Ethernet, and FS USB
  • PIC32MM with up to 64KB of Flash and 8KB SRAM offers lowest power and low voltage sleep mode with RAM retention <500 nA on PIC32 with Core Independent Peripheral Integration.
  • PIC32MZ and PIC32MX are supported by MPLAB Harmony Software Framework. PIC32MM supported by MPLAB Code Configurator (MCC) for easy set-up.

SAM 32-bit MCUs

  • From 8KB of Flash and 4KB of SRAM up to 2MB of Flash memory and 384KB of SRAM, with operating frequencies up to 300MHz
  • Innovative direct memory access (DMA) and memory implementations, which enable high-speed data transfers while freeing the processor for the application
  • "Touch-ready" capability through Qtouch capacitive touch technology with The Peripheral Touch Controller
  • Serial communication module (SERCOM) is fully software-configurable to handle I2C, USART/UART, and SPI communications to enhance interface flexibility. Select SAM series also adds RS485 and LIN-interfaces to SERCOM modules as well
  • The lowest power consumption available in an ARM Cortex-M0+-based MCU with current down to 35uA/MHz in active mode

Atmel Software Framework

The Atmel® Software Framework (ASF) is a MCU software library providing a large collection of embedded software for Atmel flash MCUs: megaAVR, AVR XMEGA, AVR UC3 and SAM devices.

  • It simplifies the usage of microcontrollers, providing an abstraction to the hardware and high-value middlewares
  • ASF is designed to be used for evaluation, prototyping, design and production phases
  • ASF is integrated in the Atmel Studio IDE with a graphical user interface or available as standalone for GCC, IAR compilers
  • ASF can be downloaded for free
