Arduino Nano Alternative 32MHz LGT8F328p LQFP32 MiniEVB

Features

• Runs at 32MHz (compared to 16MHz of the ATmega328P)
• Compatible with both 3.3V and 5V power supplies
• Advanced chip with stronger peripheral capabilities and program encryption support
• Built-in high-precision internal RC oscillator
• 12-bit ADC (Analog-to-Digital Converter)
• Onboard DAC (Digital-to-Analog Converter)
• Unique GUID (Globally Unique Identifier) for secure programming
• Built-in calibratable internal voltage references: 1.024V / 2.048V / 4.096V ±1%

Specifications

• High-performance 8-bit RISC core
• 131 instructions, 80% executed in 1 clock cycle
• 32 x 8-bit general-purpose registers
• Up to 32 MIPS at 32MHz
• Integrated one-cycle 8x8 multiplier
• Low power consumption

How to Add LGT8F328P to Arduino IDE

1. Download the zipped resources from this GitHub page.
2. Extract the ZIP and move the unzipped LGT/Avr folder to the hardware folder in your Arduino sketch directory.
   • If the hardware folder doesn’t exist, create it manually.
3. The folder structure should look like this:
   
4. Navigate to hardware/LGT/AVR, delete the existing boards.txt, and replace it with the updated boards.txt from the GitHub repository.
5. Open (or restart) the Arduino IDE.
6. Go to Tools → Board and scroll to find the LGT8F boards. Select the 32MHz version.
   • The default LGT8F328P board will appear as a 16MHz variant.

Example Arduino Code

void setup() {
  // Set pin D10 to output
  fastioMode(D10, OUTPUT);
  // Drive pin D10 low
  fastioWrite(D10, LOW);
}

void loop() {
  // Toggle pin D10 state
  fastioToggle(D10);
}
