SiFLEX01 TRANSCEIVER MODULE

DATASHEET

The information in this document is subject to change without notice.

Microcontroller

The CC430 contains an MSP430 16 bit RISC core with 16 registers. The radio registers allow access

to radio functions without the bottleneck of an intermediate interface.

There are 5 modes of operation including Active Mode and 4 low power modes with progressively lower

power achieved through disabling peripherals and clocks.

RAM is organized into 2k sectors which can be powered down to save current when not in use. Data is

not retained during power-down.

A DMA controller is included to allow direct memory to memory transfers without CPU intervention.

DMA can remain active in some sleep modes for increased power savings.

A hardware AES encryption engine is included to allow 128 bit Advanced Encryption Standard (AES)

(FIPS PUB 197) to be implemented without excessive firmware burden.

Figure 4 shows a block diagram of the CC430.
