Prodigy 30 points

Part Number: CC2500
Other Parts Discussed in Thread: CC2340R5, CC2340R2

1.- Could you please specify the mandatory components that need to be purchased to implement the attached design using the CC2500 , PIC18F46K42 and ATECC608B?

2.- How many each?

    Hi,

    Although we can't comment about the PIC or the ATECC devices, my reply is limited to the CC2500.

    This transceiver can be configured and programmed using its SPI interface, allowing a host microcontroller to communicate to it. Our examples are tailored to the MSP430 family of devices, but the commands and syntax can be extended to the PIC.  

    A reference design can be found at the CC2500 page at:

    https://www.ti.com/product/CC2500#reference-designs

    The technical documentation section of the CC2500 page contains various design suggestions and application notes for your design, such as DN038, DN400, DN503 among others. Also, sections 27, 28, 33 of the datasheet contain some references for proper PCB design. 

    Hope this helps,

    Rafael

    How many Evaluation Boards will I need to Implement a full Transmitter - Receiver System? and What Tools will I need for the Implementation?, Thanks

    Hi,

    For a system that implements a two-way communication you need a pair of CC2500EMK development boards. These boards can be connected to a pair of base boards SMARTRFTRXEBK for an easier control via the SmartRF GUI. 

    One aspect, however: the CC2500EMK is not in production anymore and therefore can't be found easily. The CC2500 part was released 20 years ago and therefore its support is limited. 

    In this case, would you consider using a newer part such as the CC2340R2 or CC2340R5 for your design? 

    Hope this helps,

    Rafael

    I was under the impression that only a single evaluation board would be required to implement both the transmitter and receiver system. Why cannot use only one evaluation board for programming the Transceiver?

    Can the new replacement of the CC2500 be programmed with Smartrf Studio 7 as well?

    Do we need a different application for programming and setting up Registers?

    Sorry, I meant that you need a pair of CC2500EM boards - the CC2500EMK comes with a pair of boards, thus requiring only one kit to be purchased for both the Keyfob + Bus.

    The CC2340R family of devices can be programmed with SmartRF Studio but version 8. This new version carries similar functionality as SmartRF Studio 7 and allows controlling the device's radio in a multitude of frequencies and PHYs. 

    However, the CC2340R2 and CC2340R5 are different than the CC2500 as they are fully programmable Cortex M0+ microcontrollers that require a running software supported by our SimpleLink F3 SDK. In practice, these devices become a fully integrated microcontroller + radio, thus not requiring an external microcontroller. To evaluate what software is avaiable that can be suited to your application, please check the available examples at our TI Resource Explorer website.

    Hope this helps,
