2.1 General Specifications Overview

The Portenta C33 is a powerful microcontroller board designed for low-cost IoT applications. Based on the high-
performance R7FA6M5BH2CBG microcontroller from Renesas®, it offers a range of key features and a low-power
design that make it well-suited for a variety of applications. The board has been designed with the same form
factor as the Portenta H7 and is backward compatible, making it fully compatible with all Portenta family shields
and carriers through its MKR-styled and high-density connectors. Table 1 summarizes the board's main features,
and Table 2, 3, 4, 5, and 6 shows more detailed information about the board's microcontroller, secure element,
Ethernet transceiver, and external memory.
