C8051F381-GQ Product Details

C8051F381-GQ Overview


Packaged in a 32-LQFP format, this MCU is available in a compact size. There are 25 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 C8051F38x series includes this electrical component. There is 64KB 64K 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, 32 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. 64kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number C8051F38. In the case of 48MHz frequency operation, it can perform efficiently. There are YES PWM channels on the device. The chip has 32 pins. The clock has 6 timers/counters to keep track of the time. 32 pins are counted on this board. There are 2 UART channels available on this board. A total of 21 ADC channels are present in this device.
