AT89LP52-20MU Product Details

AT89LP52-20MU Overview


A 44-VFQFN Exposed Pad package is included. In total, it has 36 inputs and outputs. This Microcontroller is mounted using the Surface Mount mounting type. Powered by the 8-Bit core, it offers a wide range of capabilities. The type of memory that the program uses is FLASH. The temperature range of this Microcontroller is within the range of -40°C~85°C TA. 89LP series components belong to this electrical component. Its program memory size is 8KB 8K x 8. There is a 8051 Core Processor inside MCU that provides this device with its power. MICROCONTROLLER uPs, uCs, and peripheral ICs make up the Microcontroller. Microcontroller is known that the chip has 44 terminations in total. The part works on a 8-bit basis. An output voltage of 5V volts is available for this Microcontroller chip. The Microcontroller chip has NO DMA channels. 8kB memory size belongs to the part. AT89LP52 is the base part number that you can use to find alternatives. A good performance can be achieved at a frequency of 20MHz, as long as it is operated at a low power consumption. In order for the device to work with the motor, it utilizes the PWM channel NO. On the chip, there are 44 pins that are accessible. A total of 3 timers/counters are included in the package. Devices based on the 8051 series of CPUs are embedded in the device. There's built-in FLASH memory in the equipment. It is built on a 8051 core architecture. This 8 Programmable I/O section allows you to program the device in many different ways depending on what you need. As a few examples, there are additional features like OPERATES AT 2.4 V MINIMUM SUPPLY AT 20 MHZ that are available in the software. In total, there are - channels for the ADC on this board.
