CP2102 USB-UART chip from SiLabs. Looks like around 350nm 3-metal process.

Appears to be a rebranded C8051F326 (also made by SiLabs) due to the part number on the die and the identical pinout.

Specs for the C8051F326:

  • Full speed USB 2.0 device controller
  • 25 MHz 8051 microcontroller core
  • 1536 bytes RAM (1k data + 2x 256 byte USB FIFO)
  • 16K bytes code/data flash
  • UART
  • GPIO
