LM3S9781-IQC80-C3T Product Details

LM3S9781-IQC80-C3T Overview


Packaged in a 100-LQFP format. A total of 65 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 32-Bit. The type of its program memory is FLASH. In this Microcontroller, temperature is controlled within the range -40°C~85°C TA. A Stellaris® ARM® Cortex®-M3S 9000 series electrical component is used in this application. This program has a program memory of 128KB 128K x 8 bytes, which is the size of the program. With a ARM® Cortex®-M3 Core Processor, Microcontroller is fast and efficient. ICs for MICROCONTROLLER, RISC uPs/uCs/peripheral parts. There are 100 terminations on the IC chip, which means there are 100 terminations on the integrated circuit chip. In addition, MCU chip comes with a 32-bit size. Microcontroller chip has outputs of 3.3V volts. The system has YES channels for DMA communication. There is 128kB memory size assigned to the part. Alternatives can be found by searching through the base part number LM3S9781 to find them. At a frequency of 80MHz, Microcontroller can operate efficiently. This MCU Chip uses YES PWM channels to operate. Chips have 100 pins. There are 4 timers/counters in this device. In total, it has 100 pins. It is equipped with a ARM core architecture which is integrated into it. It has 8 channels that can be accessed through UART. This device comes with a set of 2 A/D converters that have been built into it. An integrated circuit with 10 bits has a total of 10 bits.
