ATSAMR30M18A
The ATSAMR30E18A SIP consists of two vertically integrated silicon dies:
• SAM L21 ARM Cortex M0+ based microcontroller
• AT86RF212B low-power, low-voltage 700/800/900 MHz transceiver
The local communication and control interface is wired within the package. Key I/O external signals are exposed
as I/O pins.

Interconnection between SAM L21 and AT86RF212B within ATSAMR30E18A SiP
This section describes the interconnection between SAM L21 and AT86RF212B. The interface comprises a client SPI
and additional control signals. This interface is a host SPI interface in SAM L21 as shown in the following figure.
