C8051F122 Product Details

C8051F122 Overview


Packaged in a 100-TQFP format, this MCU is available in a compact size. There are 64 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 C8051F12x series includes this electrical component. There is 128KB 128K 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, 100 terminations were applied to the IC chip. 8-bits are used in Microcontroller. The MCU chip's supply output is 3.3V volts. Currently, MCU chip has NO DMA channels. 128kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number C8051F12. In the case of 100MHz frequency operation, it can perform efficiently. There are YES PWM channels on the device. The chip has 100 pins. The clock has 5 timers/counters to keep track of the time. 100 pins are counted on this board.
