AT89C2051-24SU Product Details

AT89C2051-24SU Overview


Packaged in a 20-SOIC (0.295, 7.50mm Width) format, this MCU is available in a compact size. There are 15 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 2KB 2K 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. This is a MICROCONTROLLER uPs/uCs/Peripheral IC. During the manufacturing process, 20 terminations were applied to the IC chip. 8-bits are used in Microcontroller. The MCU chip's supply output is 5V volts. Currently, MCU chip has NO DMA channels. 2kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number AT89C2051. In the case of 24MHz frequency operation, it can perform efficiently. There are NO PWM channels on the device. The chip has 20 pins. The clock has 2 timers/counters to keep track of the time. This device is embedded with a 8051 processor family, which is a powerful and efficient CPU. There is a FLASH memory feature on this equipment. With 8051 core architecture, it offers high performance. A total of 15 programmable I/Os are available on this board. There are 1 UART channels available on this board.
