Application Scenarios & Design Considerations

Piccolo Microcontroller 48-LQFP -40 to 105

Alternative Part Number

  • TMS320F28027 --: Same C2000 Piccolo F2802x family with identical core and peripherals, higher flash and memory, pin-compatible in many packages, so it can replace the original with minimal redesign.
  • TMS320F28020 --: Sister device in the same F2802x Piccolo series with the same architecture and peripheral set, offering a lower-cost, lower-memory option that is largely pin-compatible.
  • TMS320F28023 --: Another F2802x family member with the same CPU core and peripherals, providing a middle memory option that fits the same board layout and toolchain.
