C8051F331 Product Details

C8051F331 Overview


Packaged in a 20-VFQFN Exposed Pad format. A total of 17 I/Os are on the Microcontroller. Surface Mount is the mounting type of the Microcontroller that is attached to the panel. This Microcontroller is based on a core called 8-Bit. The type of its program memory is FLASH. In this Microcontroller, temperature is controlled within the range -40°C~85°C TA. A C8051F33x series electrical component is used in this application. This program has a program memory of 8KB 8K x 8 bytes, which is the size of the program. With a 8051 Core Processor, Microcontroller is fast and efficient. ICs for MICROCONTROLLER uPs/uCs/peripheral parts. There are 20 terminations on the IC chip, which means there are 20 terminations on the integrated circuit chip. In addition, MCU chip comes with a 8-bit size. Microcontroller chip has outputs of 3V volts. The system has NO channels for DMA communication. There is 8kB memory size assigned to the part. Alternatives can be found by searching through the base part number C8051F33 to find them. At a frequency of 25MHz, Microcontroller can operate efficiently. This MCU Chip uses YES PWM channels to operate. There are 4 timers/counters in this device. In total, it has 20 pins.
