ATMEGA324A-MCHR Overview
For the purpose of saving space, it is available in the 44-VQFN Dual Rows, Exposed Pad package. In this case, it is mounted using the method of Surface Mount. It is available in the Tape & Reel (TR) package. The device runs in AVR core processor. When working, the temperature should be kept at -40°C~85°C TA. The type of memory it uses is FLASH. The device has 32 I/Os. Based on the ATMEGA324A base part number, it can be compared with other components. The terminals are positioned at QUAD. 44 terminations are present in it. AVR? ATmega is the series number of this electrical component. This gadget has MICROCONTROLLER, RISC as its uPs/uCs/Peripheral IC. The structure is constructed from 44 pins. As a result, it is mounted in accordance with Surface Mount. In Microcontrollers, this component is included. The devices have a memory size of 32kB that can be used to store programs and data. 12mA is the maximum supply current. A 2/5V power source powers it. This device works well at 20MHz frequency when it is operating at a high rate of efficiency. 3 counters/timers are currently active. In order to maintain normal operation, the supply voltage (Vsup) should be maintained above 1.8V. Using oscillator type Internal makes it work.
