STM32 – a wealth of peripherals and enormous computing power
STM32 microcontrollers use 32-bit ARM cores. The first family of these processors introduced to the market - STM32F1 - is based on the ARM Cortex-M3 architecture, the subsequent ones - on newer cores, e.g. ARM Cortex-M4 or M0 and M0+. The most modern systems from the STM32F7 family are based on the ARM Cortex-M7 core, which is currently one of the most efficient and technically advanced architectures used in microcontrollers. STM32 systems offer a wide selection of analog peripherals, including fast ADCs with 12-bit resolution and sampling rates of 1 Msps or more, DACs (also 12-bit) and fast hardware comparators. Digital peripherals include, for example, extremely flexible (and numerous!) hardware timers, a rich set of communication interfaces (USART, UART, SPI, I2C, I2S, CAN, USB - including OTG - or Ethernet). Universal blocks of memory controllers, DMA, clock and reset control (RCC) and system clock monitoring (CSS) systems, as well as advanced LCD and camera controllers and graphics accelerators are invaluable.
STM32 housings and memories – there are plenty to choose from!
A particularly important advantage of the STM32 family is the richness of both housings and built-in Flash and RAM memories. Some groups (e.g. STM32F0) offer tiny, 20-pin TSSOP20 or WLCSP25 housings, but the most popular are the LQFP32, LFQP48, LFQP64 and LFQP100 housings - these are available in virtually all product lines of the STM32 family. The most complex systems - in particular those belonging to the STM32F4 and STM32F7 families - are also available in LQFP144, 176 or 208 housings, as well as UFBGA and TFBGA. Even microcontrollers from the same series and in the same housing can usually be purchased in several variants, differing in the amount of memory (Flash, RAM) and - of course - price.
STM32 microcontrollers available at the Botland store
In this category you will find several very popular models of STM32 microcontrollers, eagerly used both in evaluation boards and in end devices, mass-produced by many companies. Our offer includes immediately available microcontrollers from the STM32F1 family, belonging to various subgroups of this series: F100 and F103, equipped with large amounts of Flash memory (from 16, through 64 to 128 kB) and RAM (4, 8 or 20 kB) . We chose versions in two of the most commonly used housings: LQFP48 and LQFP64. It is worth knowing that in other categories of our store you will also find programmers/debuggers dedicated to STM32, evaluation boards and books that will allow you to quickly start your adventure with these excellent systems.
