W79E632A40PL Product Details

W79E632A40PL Overview


Packaged in a 44-LCC (J-Lead) 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 W79 series includes this electrical component. There is 128KB 128K 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, 44 terminations were applied to the IC chip. 8-bits are used in Microcontroller. The MCU chip's supply output is 5V volts. Currently, MCU chip has NO DMA channels. 128kB memory size belongs to the Chip part. In the case of 40MHz frequency operation, it can perform efficiently. There are YES PWM channels on the device. 44 pins are counted on this board.
