AT89C5122D-RDTUM Product Details

AT89C5122D-RDTUM Overview


Packaged in a 64-LQFP format, this MCU is available in a compact size. There are 46 I/Os on the Microcontroller. It is important to note that the Microcontroller has a Surface Mount mounting type. 8-Bit core is the basis for this Microcontroller. This program has a type of memory called FLASH for this MCU's program memory. Temperatures in this range are operated by this Microcontroller. The 89C series includes this electrical component. There is 32KB 32K x 8 bytes of program memory in MCU, which corresponds to the size of the program. With a 8051 Core processor, MCU is equipped with the latest technology available. 32kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number AT89C5122. In the case of 48MHz frequency operation, it can perform efficiently. The chip has 64 pins. The clock has 2 timers/counters to keep track of the time. There is a FLASH memory feature on this equipment. With 80C51 core architecture, it offers high performance. A total of 7 programmable I/Os are available on this board.
