SIM3U157-B-GQ Product Details

SIM3U157-B-GQ Overview


The package is 80-TQFP-shaped. There are 65 I/Os. In the case of the IC chip, the type of mounting is Surface Mount. Microcontroller is based on the 32-Bit core architecture. The type of program memory it uses is FLASH. Temperatures in the range of -40°C~85°C TA are operated by this Microcontroller. It is part of the SiM3U1xx series of electrical components. Having a size of 128KB 128K x 8, Microcontroller has a program memory of X bytes. A ARM® Cortex®-M3 Core Processor is at the core of this Microcontroller. This device belongs to the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. IC Chip 80 has 80 terminations. 32-bits are used for its size. IC Chip has 3V volt supply outputs. With YES DMA channels, Microcontroller chip can handle large data transfers. 128kB is the size of the memory in the IC part. Using the base part number SIM3U1, you will be able to find alternatives for the part. Using a 80MHz frequency, this electronic part can perform efficiently. On the chip, 80 pins are accessible. In addition, it comes with a ARM core architecture. In order for the device to function, it uses 2 PWM channels.
