W78E516DFG Product Details

W78E516DFG Overview


Packaged in a 44-BQFP format, this MCU is available in a compact size. There are 36 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 W78 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 8052 Core processor, MCU is equipped with the latest technology available. This is a MICROCONTROLLER uPs/uCs/Peripheral IC. During the manufacturing process, 44 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. In the case of 40MHz frequency operation, it can perform efficiently. There are NO PWM channels on the device. The chip has 44 pins. A total of 1 serial I/Os are incorporated into this part. There are 4 external interrupts included in this chip part.
