STMicroelectronics STM32F100VET6BTR

Overview

STM32F100VET6BTR from STMicroelectronics is a high-density value-line Arm® Cortex®-M3 MCU with 512 KB Flash, 32 KB SRAM, 24 MHz max CPU frequency, dual 12-bit DACs, and 16-channel 12-bit ADC-used in industrial motor control interfaces requiring real-time analog I/O and PWM timing precision.

For engineers reviewing the STM32F100VET6BTR datasheet, STM32F100VET6BTR pinout, STM32F100VET6BTR application, or STM32F100VET6BTR equivalent, key selection criteria include Flash/SRAM capacity, 100-pin LQFP package compatibility, integrated FSMC for external memory expansion, and dual DAC support for analog waveform generation.

Technical Context

The device implements an Arm Cortex-M3 core with single-cycle multiply/hardware divide, supporting deterministic real-time execution. Its clock system integrates a 4–24 MHz HSE oscillator, 8 MHz factory-trimmed HSI RC, 40 kHz LSI RC, and PLL for scalable CPU clock derivation up to 24 MHz.

Peripheral architecture includes a flexible static memory controller (FSMC) with four chip selects for SRAM/PSRAM/NOR, LCD parallel interface (8080/6800 modes), and 11 communication interfaces-including three USARTs with LIN/IrDA, two I²C, three SPIs, and CEC-enabling multi-protocol embedded connectivity.

FAQ

What is the maximum operating frequency of the STM32F100VET6BTR?

The STM32F100VET6BTR operates at a maximum CPU frequency of 24 MHz, achieved via its integrated PLL using either the 4–24 MHz HSE crystal or 8 MHz HSI RC oscillator as source. This frequency is validated across the full industrial temperature range (–40°C to +85°C) and supports zero-wait-state execution from Flash memory.

Does this MCU support external memory expansion?

Yes-the STM32F100VET6BTR includes a Flexible Static Memory Controller (FSMC) with four independent chip select outputs, supporting asynchronous and synchronous SRAM, PSRAM, and NOR flash devices. Pin mapping for FSMC signals is defined in Table 4 of DS5944 Rev 11, and timing parameters are specified in Sections 5.3.10 and 5.3.11.

How many analog-to-digital converter channels does it have?

The device integrates one 12-bit ADC with up to 16 external input channels and a 1.2 µs conversion time. It also includes an internal temperature sensor and supports dual-sampling modes. The ADC's full specification-including INL/DNL, offset/gain error, and sampling rate under various V_DD conditions-is detailed in Tables 51–54 of the datasheet.

Is the STM32F100VET6BTR pin-compatible with other STM32F100 variants?

Yes-it shares the same LQFP100 package and pinout with all STM32F100xD series members (e.g., STM32F100RDT6, STM32F100ZDT6), differing only in Flash size (384 KB vs. 512 KB) and SRAM (24 KB vs. 32 KB). Pin definitions and electrical characteristics remain identical across the LQFP100 footprint per Table 4 and Section 6.2 of DS5944 Rev 11.
