LM3S2939-IBZ50-A2 Product Details

LM3S2939-IBZ50-A2 Overview


Packaged in a 108-LFBGA format, this MCU is available in a compact size. There are 57 I/Os on the Microcontroller. It is important to note that the Microcontroller has a Surface Mount mounting type. 32-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 Stellaris® ARM® Cortex®-M3S 2000 series includes this electrical component. There is 256KB 256K x 8 bytes of program memory in MCU, which corresponds to the size of the program. With a ARM® Cortex®-M3 Core processor, MCU is equipped with the latest technology available. This is a MICROCONTROLLER, RISC uPs/uCs/Peripheral IC. During the manufacturing process, 108 terminations were applied to the IC chip. 32-bits are used in Microcontroller. The MCU chip's supply output is 2.5V volts. Currently, MCU chip has NO DMA channels. 256kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number LM3S2939. In the case of 50MHz frequency operation, it can perform efficiently. There are YES PWM channels on the device. The chip has 108 pins. The clock has 5 timers/counters to keep track of the time. 108 pins are counted on this board. With ARM core architecture, it offers high performance. There are 3 UART channels available on this board. There are a total of 1 A/D converters on the device. There are 10 bits in total on an IC chip.
