STM32L151CBU6TR Product Details

STM32L151CBU6TR Overview


The package is 48-UFQFN Exposed Pad-shaped. There are 37 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 STM32L1 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 48 has 48 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 STM32L151, you will be able to find alternatives for the part. Using a 32MHz frequency, this electronic part can perform efficiently. Devices work in YES PWM channels. On the chip, 48 pins are accessible. In total, there are 8 timers/counters on the device. The pin count is 48. There is an embedded the CORTEX-M3 CPU family inside the device, which makes it a powerful device. In addition, it comes with a ARM core architecture.
