MCU Features

General Description

These devices provide a combination of a fully featured

MCU plus an RF transmitter function, giving them great

flexibility for use in wide range of wireless I/O control ap-

plications such as industrial control, consumer prod-

ucts, subsystem controllers, etc.

Analog features include a multi-channel 12-bit A/D con-

verter. Multiple and extremely flexible Timer/Event

Counters provide full timing functions. Protective fea-

tures such as an internal Watchdog Timer and Low Volt-

age Reset coupled with excellent noise immunity and

ESD protection ensure that reliable operation is main-

tained in hostile electrical environments. An extensive

choice of oscillator functions are provided including a

fully integrated system oscillator which requires no ex-

ternal components for its implementation. The ability to

operate and switch dynamically between a range of op-

erating modes using different clock sources gives users

the ability to optimise microcontroller operation and

minimise power consumption. The devices also include

flexible I/O programming features Time-Base functions

and a range of other features.

The RF transmitter is a high performance and easy to

use transmitter operating in the 300MHz to 450MHz fre-

quency band. One only needs to add a crystal reference

frequency, and a limited number of external compo-

RF Transmitter Features

nents to create a complete and versatile RF transmitter

system. The device is capable of delivering more than

+9dBm into a 50

small form factor transmitter to operate near the maxi-

mum limit of the transmission regulations. The device

can operate with ASK - Amplitude Shift Keying, and

OOK - On-Off Keying, UHF receiver types from

wide-band super-regenerative radios to narrow-band,

high performance super-heterodyne receivers. The

data rate is higher than 10kbps, allowing the device to

support more complicated control protocols.

For enhanced power saving, the device includes a data

tracking function. The data tracking function enables the

PLL to be activated as long as high transient data input

trigger signals are received. The PLL will also be auto-

matically switched off if there are no data input tran-

sients for a time exceeding approximately 300ms. As

there is a reference clock input on line PB0, the MCU

can use its internal RC clock rather than using an addi-

tional crystal for the system clock. These features add

up to ensure that the devices can offer excellent capabil-

ities in terms of functionality and power-saving as well

as being highly cost effective in a huge range of remote

wireless applications
