Microcontrollers

Microchip Technology's ATMEGA809-AF is a high-performance microcontroller unit (MCU) that belongs to the AVR Enhanced series. It is designed to provide a range of features and capabilities that make it suitable for a wide range of applications.

Description:

The ATMEGA809-AF is a 48-pin, low-power CMOS 8-bit microcontroller based on the enhanced AVR RISC architecture. It features a high-speed embedded nonvolatile program and EEPROM memory, an I/O interface with internal pull-up resistors, and a system boot mode that allows for fast wake-up times.

Features:

1. CPU: Enhanced AVR RISC architecture with 16 MHz maximum operating frequency.
2. Memory: 8KB In-System Programmable Flash with read-while-write capability, 1KB EEPROM, and 6KB SRAM.
3. I/O: 23 programmable I/O lines with internal pull-up resistors, and 3 additional I/O lines for reset, Vcc, and GND.
4. ADC: 8-channel, 10-bit Analog-to-Digital Converter with optional differential input stage.
5. Communication interfaces: 1 USART for full-duplex UART/SPI/I2C operation, and 1 SPI with hardware slave select management.
6. Timers/Counters: 3 general-purpose 16-bit timers/counters with 8-bit resolution, and watchdog timer.
7. Interrupts: 18 interrupt sources, 5-level priority, and non-maskable interrupt (NMI) support.
8. Power management: Power-save mode, power-down mode, and idle mode for low-power consumption.
9. Security: JTAG interface for programming and debugging, and a bootloader mode for secure firmware updates.
10. Operating temperature range: -40°C to +85°C.

Applications:

The ATMEGA809-AF is suitable for a wide range of applications due to its versatile features and low-power consumption. Some potential applications include:
