1 Overview of Microchip Cortex-M7 based MCUs
The PIC32CZ CA family and SAM E70/S70/V7x family of Microcontrollers (MCUs) from Microchip are high-performing MCUs with an Arm Cortex-M7 core. This series of MCUs offers a rich set of peripherals with a large built-in code and data memory. To ensure high-speed, low-latency, and deterministic access for time-critical code and data, the Arm Cortex-M7 core is connected to the TCM.
PIC32CZ CA Family Microcontrollers
The PIC32CZ CA series of microcontrollers features a high-performance Arm Cortex-M7 core and is designed with an advanced memory architecture. These microcontrollers offer up to 8 MB of Flash memory and 1 MB of SRAM to meet the rigorous memory demands of sophisticated applications. The Arm Cortex-M7 core includes an interface with a dedicated TCM that incorporates Error Correction Code (ECC) for enhanced high-speed, low-latency, and deterministic processing.
The PIC32CZ CA9x family offers an integrated Hardware Security Module (HSM) and a diverse range of connectivity features, making it an outstanding choice for applications in the automotive and industrial sectors, as well as other areas requiring robust security measures, such as communications encryption, secure boot processes, authentication protocols, and secure key storage.
It offers an extensive array of connectivity features, such as high-speed USB, CAN FD, Serial Quad I/O (SQI), Secure Digital High Capacity (SDHC), Inter-IC Sound (I2S™), Media Local Bus (Media LB™), External Bus Interface (EBI), 10/100/1000 Ethernet, and Serial Communication Interface (SERCOM).
These MCUs are equipped with a Memory Protection Unit (MPU) to enhance security, incorporate a clock failure detection mechanism complemented by a fail-safe internal RC oscillator, and provide write protection for selected peripherals to ensure system integrity.
SAM E70/S70/V7x Family Microcontrollers
The SAM E70/S70/V7x series of microcontrollers are equipped with a high-performance Arm Cortex-M7 core and features an advanced memory architecture, including up to 384 KB of multi-port internal SRAM.
In conjunction with a robust set of peripherals, these microcontrollers are exceptionally suitable for sophisticated applications, such as IoT and Smart Energy gateways, industrial automation, and building control systems.
The comprehensive peripheral set encompasses an Ethernet MAC with dedicated support for Ethernet AVB, high-speed USB with an integrated PHY, I2S, QSPI, and dual CAN-FD. For additional information on these device’s peripherals and package options, refer to the relevant data sheets.
To facilitate high-speed, low-latency, and deterministic processing for critical code and data, the Arm Cortex-M7 core is interfaced with TCM. A multi-layer bus matrix also provides efficient interconnection between the peripherals and the multi-port RAM.
Overall, the SAM E70/S70/V7x family of devices delivers an unparalleled combination of connectivity options, top-tier Arm Cortex-M7 processing power, and a distinctive multi-port memory architecture, positioning it as a leading choice for high-end applications.
