AT89C55WD-33JC Product Details

AT89C55WD-33JC Overview


The package is in PDIP format. The MCU has 32 I/O ports. This Microcontroller belongs to the MICROCONTROLLER uPs/uCs/peripheral ICs type. During the manufacture of the IC chip, there is a number 44 of terminations. A 8-bit operation is performed by this part. There is an output of 5V volts from the Microcontroller chip. A total of NO DMA channels are available on MCU chip. This MCU is implemented with 20kB memory. It exhibits good efficiency when it operates at a frequency of 33MHz and it is able to operate at a high frequency. It is possible for the device to work with the motor using the PWM channel NO. It is possible to access the 44 pins on the chip through the 44 pins. It is equipped with 3 timers and counters. There's an integrated FLASH memory in the equipment. There is a 8051 core architecture integrated into it. Among the eight programmable I/O sections, there are many different ways in which it can be programmed.
