Rq Atmega328P microcontroller with bootloader

The high-performance Microchip picoPower® 8-bit AVR® RISC-based microcontroller combines 32 KB ISP Flash memory with read-while-write capabilities, 1024B EEPROM, 2 KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented Two-Wire serial interface, SPI serial port, a 6-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, and five software selectable power saving modes. The device operates between 1.8-5.5 volts.

By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed.

High endurance non-volatile memory segments

• In system self-programmable flash program memory
• Programming Lock for software security

Peripheral features

• Two 8-bit Timer/Counter with separate prescaler, compare mode.
• One 16-bit Timer/Counter with separate prescaler, compare mode, and capture mode
• Temperature measurement
• Programmable serial USART and watchdog timer with separate on-chip oscillator

Unique features compared to other microcontrollers (ARM, 8051, PIC):

• Power-on reset and programmable brown-out detection
• Internal calibrated oscillator
• External and Internal interrupt sources
• Six sleep modes: Idle, ADC noise reduction, power-save, power-down, standby, and extended standby
