SIM3U156-B-GM Product Details

SIM3U156-B-GM Overview


Packaged in a 64-VFQFN Exposed Pad format, this MCU is available in a compact size. There are 50 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 SiM3U1xx series includes this electrical component. There is 128KB 128K 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, 64 terminations were applied to the IC chip. 32-bits are used in Microcontroller. The MCU chip's supply output is 3V volts. Currently, MCU chip has YES DMA channels. 128kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number SIM3U1. In the case of 80MHz frequency operation, it can perform efficiently. There are YES PWM channels on the device. The chip has 64 pins. The clock has 2 timers/counters to keep track of the time. With ARM core architecture, it offers high performance. A total of 65 programmable I/Os are available on this board.
