AT89LP2052-20SU Product Details

AT89LP2052-20SU Overview


Packaged in a 20-SOIC (0.295, 7.50mm Width) format. A total of 15 I/Os are on the Microcontroller. Surface Mount 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 89LP series electrical component is used in this application. This program has a program memory of 2KB 2K 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. There are 20 terminations on the IC chip, which means there are 20 terminations on the integrated circuit chip. In addition, MCU chip comes with a 8-bit size. Microcontroller chip has outputs of 3V volts. The system has NO channels for DMA communication. There is 2kB memory size assigned to the part. Alternatives can be found by searching through the base part number AT89LP2052 to find them. At a frequency of 20MHz, Microcontroller can operate efficiently. This MCU Chip uses YES PWM channels to operate. Chips have 20 pins. There are 2 Timer timers/counters in this device. 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 15 Programmable I/O section, it can be programmed in many different ways. It has 8 channels that can be accessed through UART. This device uses 2 PWM channels to generate the voltage.
