RTOS/CC430F5123: CC430F5123

na jang young

Part Number: CC430F5123

Tool/software: TI-RTOS

above CC430F5123 is set for rf frequency band 433, 868 or some.

but in korea above RF bandwide are not allowed. so.i want to change 433 mhz band to 447mhz.

how can i do so ,for example, can i have a reviced circuit for 447mhz which is allowed in our country

for data exchange.

As page 68 in www.ti.com/.../cc430f5123.pdf shows this chip covers the range 389 MHz to 464 MHz in the 400 MHZ band.

The frequency programming is covered in 25.3.3.9 in www.ti.com/.../slau259e.pdf

hello,

thanks for your info. i understand a little for rf.

can i have "Typical Application Circuit CC430F5123 for rf 447mhz receiver module".

i see a lots of rf 433 ,868mhz info including "Typical Application Circuit CC430F51xx".

thanks,

You can use the 433 MHz application circuits for 447 MHz since the frequency difference is limited.

hello TER,

i will develope rf447mhz receiver sample as you requested.

the main controler will be cc430f5123 and helical antenna to save money and very simple function.

i have the circuit diagram for cc430f5123 from ti' datasheet.

but in realty, it is very complicate to design without your EVM or BOM etc.

please give me more information for designing cc430f5123 device and rf447mhz antenna.

i will attatch a simple JPG file which confiure my expecting devices. it is impossible.

regards,

What do you refer to by " it is impossible."?
