AT89C55WD-24PU Overview


For space savings, it is available in the 40-DIP (0.600, 15.24mm) package. Through Hole is used for mounting. This item can be found in package Tube. There is a 8051 as core processor in this device. When working, it is recommended that the temperature be kept at -40°C~85°C TA. FLASH is the type of program memory used by it. There are 32 I/Os on the board. Based on the AT89C55 base part number, it can be compared with other components. 89C is the series number of this electrical component. In data storage, FLASH is used as the memory type. The structure is constructed from 40 pins. According to Through Hole, it is mounted. The devices have a maximum memory size of 20kB that can be used to store programs and data. The core architecture of the system is 8051. At a frequency of 33MHz, it exhibits excellent efficiency. The supply voltage of 5V's adaptability can be fully utilised by designers. A total of 3 timers/counters have been set up. A maximum frequency of 24MHz is set for the device. The operating temperature should be lower than 85°C. Temperatures above -40°C are recommended for working. There are a total of 32 programmable I/Os available. Internal is the oscillator type it uses.
