LGT8F08/88/328 (AVR Compatible)

8F328 Board Features

  • 8F328P-U MCU used by the LGT8F328P, is a Atmel MEGA328P compatible chip.
  • 8F328D architecture design is relatively new, peripheral functions far stronger than Atmel MEGA328. Especially the program encryption ability is far more than MEGA328.
  • 8F328D can use 3V3 and 5V power supply running at 16M frequency, excellent level compatibility.
  • Built-in high-precision RC, no external crystal can be stable operation.
  • Less peripheral parts, circuit design is simple.
  • 12-bit ADC (analog-to-digital conversion)
  • On board DAC
  • Owned GUID (unique ID) can be used for chip program encryption
  • Built-in internal 1.024V / 2.048V / 4.096V ± 1% calibratable reference voltage source

Programming Guide

Toolchain use

  • IAR Embedded Workbench 8.0 for AVR
  • Hardware download and debug tool - SWDICE mkII Pro
  • Code downloader tool - lgtmix_isp

Use in arduino IDE LGT8F328D

  • All of our boards already had arduino bootloader
  • Install larduino HSP from here DL to get support in arduino IDE, install guide refer to "Install.txt"
  • Choose board larduino-core w/LGT8F328D, the rest is the same as use arduino pro mini.
  • Detail guide please see here. File:LGT8FX8D mini arduino app.pdf


To Arduino Guide



LGT toolchain

  • Current available board, ocrobot board 8f328p or d, arduino xi 8f328d, larduino mini (retired) 8f88a, itead lite (retired)
