C8051F391-A-GMR Product Details

C8051F391-A-GMR Overview


Packaged in a 24-WFQFN Exposed Pad format, this MCU is available in a compact size. There are 21 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 C8051F39x 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. 16kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number C8051F39. In the case of 50MHz frequency operation, it can perform efficiently.
