APPLICATION NOTE
Atmel AT04389: Connecting SAMD20E to the AT86RF233
Transceiver
Atmel SAMD20
Description
This application note describes a method to connect an Atmel
®
ATSAMD20E
microcontroller to an Atmel AT86RF233 IEEE
®
802.15.4 Wireless Transceiver. The
32-pin SAM D20E is gaining popularity as a baseband processor for wireless
applications. The current development platform uses the 64-pin SAM D20J on the
ATSAMD20-XPRO and RF233-XPRO extender board. This combination is supported
in Atmel Studio 6. To translate firmware written for the 64-pin platform to a 32-pin
target product several layers of signal mapping; such as the 64-pin to 32-pin
conversion and header I/O constraints, have to be reconciled. This paper offers a
solution that matches the target product topology to the legacy development platform
as closely as possible.
