AT89C55WD-24JI Product Details
AT89C55WD-24JI Overview
Packaged in a 44-LCC (J-Lead) format, this MCU is available in a compact size. There are 32 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 89C series includes this electrical component. There is 20KB 20K 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. 8-bits are used in Microcontroller. Currently, MCU chip has NO DMA channels. Alternatives can be found by looking at the base part number AT89C55. There are NO PWM channels on the device. 44 pins are counted on this board. This device is embedded with a 8051 processor family, which is a powerful and efficient CPU.
