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
The feature compare
| Feature | LGT8F328P | atmega328P |
|---|---|---|
| DAC output | Yes | - |
| Internal reference resoltuion | ±0.5% | ±1.5% |
| PWM dead zone control | Yes | - |
| High current push - pull PWM | Yes | - |
| Computing Accelerator (DSC) | Yes | - |
| Stacking expansion system | Yes | - |
| Speed | 32M | 16M |

Programming Guide
Toolchain use
- IAR Embedded Workbench 8.0 for AVR
- MPLAB+PICC for PIC
- Hardware download and debug tool - SWDICE mkII Pro
- Code downloader tool - lgtmix_isp
use official programmer, burning arduino bootloader
Use in arduino IDE LGT8F328D
- All of our boards already had arduino bootloader
- Install larduino HSP from here our github folder in the link below, 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.
