AT91M42800A-33AU Product Details

AT91M42800A-33AU Overview


Packaged in a 144-LQFP format. A total of 54 I/Os are on the Microcontroller. Surface Mount is the mounting type of the Microcontroller that is attached to the panel. This Microcontroller is based on a core called 16/32-Bit. The type of its program memory is ROMless. In this Microcontroller, temperature is controlled within the range -40°C~85°C TA. A AT91 series electrical component is used in this application. This program has a program memory of -- bytes, which is the size of the program. With a ARM7® Core Processor, Microcontroller is fast and efficient. ICs for MICROCONTROLLER, RISC uPs/uCs/peripheral parts. There are 144 terminations on the IC chip, which means there are 144 terminations on the integrated circuit chip. In addition, MCU chip comes with a 32-bit size. Microcontroller chip has outputs of 3V volts. The system has NO channels for DMA communication. Alternatives can be found by searching through the base part number AT91M42800A to find them. At a frequency of 33MHz, Microcontroller can operate efficiently. This MCU Chip uses YES PWM channels to operate. Chips have 144 pins. There are 6 timers/counters in this device. In total, it has 144 pins. The ARM7 CPU family is embedded in the device, so it can handle a wide range of operations. The equipment has a FLASH, ROMless memory that is built in. It is equipped with a ARM core architecture which is integrated into it. As an example, one of the additional features that you can use is ALSO REQUIRES 5V SUPPLY.
