AT89LP6440-20MU Product Details

AT89LP6440-20MU Overview


The package is 44-VFQFN Exposed Pad-shaped. There are 38 I/Os on the Microcontroller. It is important to note that the Microcontroller has a Surface Mount mounting type. Powered by the 8-Bit core, it offers a wide range of capabilities. This Microcontroller's program memory type is FLASH. The Microcontroller runs in -40°C~85°C TA Operating Temperature. It is part of the 89LP series of electrical components. Having a size of 64KB 64K x 8, Microcontroller has a program memory of X bytes. With a 8051 Core Processor, Microcontroller is fast and efficient. MICROCONTROLLER uPs, uCs, and peripheral ICs make up the Microcontroller. 44 is the number of terminations on the IC chip that are present. In addition, MCU chip comes with a 8-bit size. IC Chip has 3.3V volt supply outputs. A total of NO DMA channels are available on MCU chip. Its memory size is 64kB. AT89LP6440 serves as a base part number to find alternatives. In the case of 20MHz frequency operation, it can perform efficiently. There are a total of YES channels in the device. It is possible to access the 44 pins on the chip through the 44 pins. The clock has 3 timers/counters to keep track of the time. In addition, there are several other features that can be found in the software, including OPERATES AT 1.8 V MINIMUM SUPPLY AT 12 MHZ.
