SIM3U146-B-GM Product Details

SIM3U146-B-GM Overview


Packaged in a 64-VFQFN Exposed Pad format. A total of 50 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 SiM3U1xx series electrical component is used in this application. This program has a program memory of 64KB 64K 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 64 terminations on the IC chip, which means there are 64 terminations on the integrated circuit chip. In addition, MCU chip comes with a 32-bit size. Microcontroller chip has outputs of 3V volts. The system has YES channels for DMA communication. There is 64kB memory size assigned to the part. Alternatives can be found by searching through the base part number SIM3U1 to find them. At a frequency of 80MHz, Microcontroller can operate efficiently. This MCU Chip uses YES PWM channels to operate. Chips have 64 pins. There are 2 timers/counters in this device. It is equipped with a ARM core architecture which is integrated into it. In the 65 Programmable I/O section, it can be programmed in many different ways.
