Microchip Technology, Inc. Microcontrollers ATSAME54P20A-AF

The Microchip 32-bit ARM Cortex-M4F microcontroller, part number 47AC7950, operates at a maximum frequency of 100 MHz and is housed in a TQFP-128 package. It supports a voltage range of 1.71V to 3.63V and is rated for operating temperatures from -40¬8C to +125¬8C. The microcontroller features a combined instruction and data cache of 4 KB, a memory protection unit, and a floating-point unit. Memory options include up to 1 MB of Flash with error correction code (ECC) and up to 256 KB of SRAM, with additional tightly coupled memory and backup registers. It includes a variety of high-performance peripherals such as a 32-channel Direct Memory Access Controller (DMAC), USB 2.0 interface, Ethernet MAC, and multiple serial communication interfaces. The device also integrates dual 12-bit ADCs and DACs, as well as cryptographic features like AES and a true random number generator. This microcontroller is suitable for applications requiring robust processing capabilities, extensive peripheral support, and high reliability in harsh environments.
