The Pro Trinket 3V uses the Atmega328P chip, which is the same core chip in the Arduino. However, it uses 3V logic and 12MHz clock. It's like an Arduino Pro Mini with more pins and USB tossed in. The Pro Trinket has 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM. It has onboard USB bootloading support. Optiboot is supported, so you can either program your Pro Trinket over USB or with a FTDI cable/adapter.
