ATMEGA48-20AU Overview
Packaged in a 32-TQFP format. There are 23 I/O ports on this device. This Microcontroller is mounted using the Surface Mount mounting type. The 8-Bit core is the core of the MCU. As far as its program memory type is concerned, it is FLASH. Temperatures in this range are operated by this Microcontroller. It is part of the AVR® ATmega series of electrical components. This program has a program memory of 4KB 2K x 16 bytes, which is the size of the program. A AVR Core Processor is at the core of this Microcontroller. This device falls under the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. The MCU has a number of 32 terminals. The part works on a 8-bit basis. Microcontroller chip has outputs of 3V volts. There are NO DMA channels on this Microcontroller chip. This IC part has a memory size of 4kB. Alternatives can be found by searching through the base part number ATMEGA48 to find them. A good performance can be achieved at a frequency of 20MHz, as long as it is operated at a low power consumption. It is possible to access the 32 pins on the chip. There are 3 timers/counters in this device. A total of 8 channels of ADC are available on this device. A total of 6 PWM channels are used by the device. An 1-channel PWM controller is used by the device. MCU chip is equipped with 1 serial I/Os in the part. As part of the part, there are 2 external interrupts that can be used.
