C8051F557-IMR Product Details

C8051F557-IMR Overview


Packaged in a 24-WFQFN Exposed Pad format, this MCU is available in a compact size. There are 18 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 C8051F55x series includes this electrical component. There is 16KB 16K 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, 24 terminations were applied to the IC chip. 8-bits are used in Microcontroller. The MCU chip's supply output is 2.1V volts. Currently, MCU chip has NO DMA channels. 16kB memory size belongs to the Chip part. In the case of 50MHz frequency operation, it can perform efficiently. There are YES PWM channels on the device. 24 pins are counted on this board.
