SAMC21J in SAM Microcontrollers Family
The SAMC21J is a series of 32-bit ARM Cortex-M0+ microcontrollers by Microchip Technology designed for robust industrial and automotive applications. Operating at up to 5V, these MCUs provide high noise immunity and simplified power regulation compared to standard 3.3V alternatives. The family integrates dual CAN-FD interfaces and hardware-based motor control support, making it a reliable solution for harsh environments requiring deterministic performance and resilient communication protocols without external level shifters.
Variants in This Sub-Family
Variants within the SAMC21J sub-family are distinguished primarily by their Flash memory density, ranging from 32KB to 256KB, and their corresponding SRAM allocations. Packaging options typically include 64-pin TQFP and VQFN formats. While the J-suffix denotes the specific pin count, individual part numbers also specify temperature grades, ranging from standard industrial -40C to 85C up to AEC-Q100 Grade 1 qualified automotive versions rated for 125C operation.
