Microchip ATmega328P-AU IC 8-bit AVR Microcontroller with 32K Bytes In-System Programmable Flash

ATmega328P-AU MCU 8-bit AVR RISC 32KB Flash 2.5V/3.3V/5V 32-Pin TQFP

ATmega328PB-AU MCU 8-Bit ATmega AVR RISC 32KB Flash 5V 32-Pin TQFP

Overview:

The Atmel® ATmega328P is a low-power CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture.

By executing powerful instructions in a single clock cycle, the ATmega328P achieves throughputs approaching 1MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

Features:

● High performance, low power AVR® 8-bit microcontroller

● Advanced RISC architecture

● 131 powerful instructions – most single clock cycle execution

● 32 * 8 general purpose working registers

● Fully static operation

● Up to 16MIPS throughput at 16MHz

● On-chip 2-cycle multiplier

● High endurance non-volatile memory segments

● 32K bytes of in-system self-programmable flash program memory

● 1Kbytes EEPROM ● 2Kbytes internal SRAM

● Write/erase cycles: 10,000 flash/100,000 EEPROM

● Optional boot code section with independent lock bits

● In-system programming by on-chip boot program

● True read-while-write operation

● Programming lock for software security

● Peripheral features

● Two 8-bit Timer/Counters with separate prescaler and compare mode

● One 16-bit Timer/Counter with separate prescaler, compare mode, and capture mode

● Real time counter with separate oscillator

● Six PWM channels

● 8-channel 10-bit ADC in TQFP and QFN/MLF package

● Temperature measurement

● Programmable serial USART

● Master/slave SPI serial interface

● Byte-oriented 2-wire serial interface (Phillips I2 C compatible)

● Programmable watchdog timer with separate on-chip oscillator

● On-chip analog comparator

● Interrupt and wake-up on pin change

● Special microcontroller features

● 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

● I/O and packages
● 23 programmable I/O lines
● 32-lead TQFP, and 32-pad QFN/MLF
● Operating voltage:
● 2.7V to 5.5V for ATmega328P
● Temperature range:
● Automotive temperature range: –40°C to +125°C
● Speed grade:
● 0 to 8MHz at 2.7 to 5.5V (automotive temperature range: –40°C to +125°C)
● 0 to 16MHz at 4.5 to 5.5V (automotive temperature range: –40°C to +125°C)
● Low power consumption
● Active mode: 1.5mA at 3V - 4MHz
