looks an interesting component for low cost short range applications
it supports the MiWi protocol which I mentioned in my last post

were you talking about the controller that i posted? MRF49XA?
 

yes, I was looking at the MRF49XA PICtail Plus Daughter Board which gives some details

can i program the MRF49XA using ICD2?

oooh,okay. can i use rfPIC12F675K as transmitter and MRF49XA as receiver? i think both of the support FSK.

Looking at the specifications they are not compatible (they use different frequencies etc).
You could use a couple of PICs with MRF49XAs

ow.okay.but wouldn't it add to the power consumption of the overall system? i mean, PIC + MRF49XAs > power consumption than rfPIC12F675K alone?
 

you could use a low power PIC and the MRF49XA has power saving modes so you only switch it on when transmitting
you need to do the calculations for cost, power consumptions, etc.
e.g. you could use the rfPIC12F675K to talk to a rfRXD0420 receiver connected to a PIC
rfRXD0420

have alook at

this helped a lot.last question!....(i hope) the PIC that i should connect to rfRXD0420 should have UART capability right?
 

I think you need to read thru the application notes for the device, e.g. on page
rfRXD0420

it may be simpler to buy a receiver module
**broken link removed**

but make sure it will talk to a rfPIC12F675K.
You are getting to a very specialised area, it may be worth putting your questions on the microchip forum

do you have an IM account? can i just ask you through it? haha. if it isn't too much :)
 

Hay you can use MRF24J40MA ready made microchip's module which needs only SPI interface. I think if you use MiWi rather than zigbee it will be cheaper as horace1 suggested somewhere. I have used it with atmel microcontroller. It is working on ZigBee. but now I am implemeting it with MiWi. Right now I am facing problem but it is because it's my first time with miwi. In conclusion MiWi is better solution for you using low power nano Watt technology MCU of microchip
