SKU CH-5Y3K-XG703

A 40-pin RF microcontroller with 256 KB flash in a VQFN package

  • Product typeICs Semicoductors
  • RF microcontroller with 256 KB flash memory
  • 40-pin VQFN package for compact PCB integration
  • CC2540 core supports low-power wireless applications
  • Semiconductor-grade IC for embedded system designs

RF microcontroller for embedded wireless designs

The YINGHUA CC2540TF256RHAR is an RF microcontroller built for engineers developing compact wireless nodes. Its VQFN40 package suits space-constrained printed-circuit boards in sensor networks, remote controls or medical monitors. The device integrates radio and processing functions in a single new component.

256 KB flash with 40-pin VQFN footprint

On-chip flash of 256 KB holds application code and data for typical low-power protocols. The 40-pin VQFN outline limits I/O count, so designs needing many peripherals or external memory interfaces will require a larger package. Complex stacks or heavy buffering may exceed the available resources.

Questions about this item

Will the CC2540TF256RHAR share a PCB footprint with other VQFN40 parts I already use?

Yes, the VQFN40 package uses the standard 40-lead very-thin quad flat no-lead outline, so any existing footprint for that package will fit.

How can I confirm the CC2540TF256RHAR is running after I solder it?

Apply power and verify the device responds to its debug interface; successful communication proves the MCU is active.
