AT89C55WD-24PI Product Details

AT89C55WD-24PI Overview


Packaged in a 40-DIP (0.600, 15.24mm) format. A total of 32 I/Os are on the Microcontroller. Through Hole is the mounting type of the Microcontroller that is attached to the panel. This Microcontroller is based on a core called 8-Bit. The type of its program memory is FLASH. In this Microcontroller, temperature is controlled within the range -40°C~85°C TA. A 89C series electrical component is used in this application. This program has a program memory of 20KB 20K x 8 bytes, which is the size of the program. With a 8051 Core Processor, Microcontroller is fast and efficient. ICs for MICROCONTROLLER uPs/uCs/peripheral parts. In addition, MCU chip comes with a 8-bit size. The system has NO channels for DMA communication. There is 20kB memory size assigned to the part. Alternatives can be found by searching through the base part number AT89C55 to find them. At a frequency of 24MHz, Microcontroller can operate efficiently. This MCU Chip uses NO PWM channels to operate. Chips have 40 pins. There are 3 timers/counters in this device. In total, it has 40 pins. The 8051 CPU family is embedded in the device, so it can handle a wide range of operations. The equipment has a FLASH memory that is built in. It is equipped with a 8051 core architecture which is integrated into it. In the 32 Programmable I/O section, it can be programmed in many different ways.
