AT89LP6440-20JU Product Details

AT89LP6440-20JU Overview


Packaged in a 44-LCC (J-Lead) format, this MCU is available in a compact size. There are 38 I/Os on the Microcontroller. It is important to note that the Microcontroller has a Surface Mount mounting type. 8-Bit core is the basis for this Microcontroller. This program has a type of memory called FLASH for this MCU's program memory. Temperatures in this range are operated by this Microcontroller. The 89LP series includes this electrical component. There is 64KB 64K x 8 bytes of program memory in MCU, which corresponds to the size of the program. With a 8051 Core processor, MCU is equipped with the latest technology available. This is a MICROCONTROLLER uPs/uCs/Peripheral IC. During the manufacturing process, 44 terminations were applied to the IC chip. 8-bits are used in Microcontroller. The MCU chip's supply output is 3.3V volts. Currently, MCU chip has NO DMA channels. 64kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number AT89LP6440. In the case of 20MHz frequency operation, it can perform efficiently. There are YES PWM channels on the device. The chip has 44 pins. The clock has 3 timers/counters to keep track of the time. This device is embedded with a 8051 processor family, which is a powerful and efficient CPU. There is a FLASH memory feature on this equipment. With 8051 core architecture, it offers high performance. A total of 38 programmable I/Os are available on this board. As a few examples, there are additional features like OPERATES AT 1.8 V MINIMUM SUPPLY AT 12 MHZ that are available in the software. A total of 8 Channel ADC channels are present in this device.
