ATMEGA644P-20AU Product Details
ATMEGA644P-20AU Overview
Packaged in a 44-TQFP format, this MCU is available in a compact size. 32 I/Os are available. Using the Mounting Type Surface Mount, the MCU is mounted on PCB. As the name implies, this Microcontroller is based on the 8-Bit core. The type of its program memory is FLASH. -40°C~85°C TA is the temperature range at which this Microcontroller operates. An electrical component of this type belongs to the AVR® ATmega series. 64KB 32K x 16 is the size of its program memory. The AVR Core Processor powers the device and is one of its key features. This Microcontroller belongs to the MICROCONTROLLER, RISC uPs/uCs/peripheral ICs type. 44 is the number of terminations on the IC chip that are present. 8-bits are used in Microcontroller. Input voltage for the chip is 5V volts. Currently, MCU chip has NO DMA channels. The part has a memory size of 64kB. ATMEGA644P serves as a base part number to find alternatives. The efficiency of this device can be improved when operating at a frequency of 20MHz. On the chip, there are 44 pins that are accessible. Using the timer/counter system, it has 3 timers/counters. There is a EEPROM, FLASH memory feature on this equipment. The ADC channels on this device total 8 in number. A total of 6 PWM channels are used by the device. There are 1 I2C channels included in the part, which has been designed for the purpose.
