SIM3U157-B-GM Product Details

SIM3U157-B-GM Overview


Packaged in a 92-VFLGA Dual Rows, Exposed Pad 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 SiM3U1xx 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 92 terminations on the IC chip, which means there are 92 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 128kB 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. Chips have 92 pins. It is equipped with a ARM core architecture which is integrated into it. This device uses 2 PWM channels to generate the voltage.
