STM32F091CCT6 - 48MHz Cortex-M0 MCU with 256KB Flash | ST
MPN： STM32F091CCT6 ✓ 啟用中STM32F091CCT6 概覽
A microcontroller is a programmable semiconductor that combines a processor core, memory, peripherals, and interface circuitry on one integrated circuit. The STM32F0 access-line MCU family belongs to the broader embedded-controller hierarchy: ARM Cortex-M0 processor core, 32-bit microcontroller, embedded system controller, and semiconductor. Its combination of processing speed, peripheral coverage, and compact package makes it suitable for industrial equipment, sensor nodes, motor controls, and CAN-connected products.
Key features include a 48 MHz ARM Cortex-M0 core, 256 KB of Flash, and CAN support capable of operating up to 1 Mbit/s. The device also provides 12 timers, a 12-bit ADC, and a DAC according to the manufacturer datasheet. These resources support applications that require simultaneous digital control, analog measurement, waveform generation, and field-bus communication without using several separate integrated circuits.
The STM32F091xB and STM32F091xC devices use a 32-bit RISC architecture and integrate high-speed embedded Flash memory. The CAN interface supports specifications 2.0A and 2.0B, including standard 11-bit and extended 29-bit identifiers. This makes the MCU appropriate for industrial networking, actuator control, and embedded gateways where deterministic protocol support and compact integration are important.
Typical applications include CAN-connected sensor hubs, industrial motor controllers, compact PLC modules, medical or diagnostic instrumentation, LED-control systems, and battery-powered IoT equipment. The ADC can acquire analog process variables, the DAC can generate reference or control waveforms, and the timer bank can generate PWM signals for motors, valves, lamps, and power-conversion stages.
PCB design should follow the manufacturer pinout and reference-circuit guidance. Place all decoupling capacitors close to the appropriate supply pins, provide a stable clock circuit, route sensitive analog inputs away from switching nodes, and confirm programming, reset, and boot-strapping connections before layout release. The LQFP package also requires adequate solder mask clearance and thermal copper for dependable manufacturing.
This product page combines the manufacturer specifications with application guidance, package information, comparison parameters, and practical design considerations. It helps engineers evaluate the STM32F091CCT6 for 48 MHz Cortex-M0 designs that require 256 KB Flash, CAN connectivity, 12 timers, ADC and DAC resources, and a 48-LQFP footprint.

典型應用
STM32F091CCT6 適用於 6 應用s: CAN-Connected Industrial Sensor Nodes, Compact Industrial Motor Control, Medical and Diagnostic Instrumentation, IoT and Connected Sensor Hubs, LED and Lighting Control Modules, Battery-Powered Embedded Control.
CAN-Connected Industrial Sensor Nodes
The STM32F091CCT6 fits compact CAN sensor nodes because its 48 MHz ARM Cortex-M0 core can handle protocol processing and control logic while the integrated CAN controller communicates at up to 1 Mbit/s. The 256 KB Flash provides room for application firmware, calibration data, and boot logic. A 12-bit ADC can acquire sensor signals, while CAN 2.0A/2.0B support permits standard or extended identifiers. Using the MCU in a 48-LQFP package reduces board area, but designers should reserve clean routing for the CAN transceiver and provide local decoupling close to the supply pins.
推薦
Compact Industrial Motor Control
The STM32F091CCT6 is suitable for compact motor-control subsystems because its 48 MHz Cortex-M0 core supports fast digital control, while 12 timers can generate PWM and capture timing events. The 12-bit ADC is useful for sensing current, position, or analog command signals, and the 10-bit DAC can provide an analog reference where required. The 256 KB Flash is suitable for embedded control code, while CAN allows the controller to participate in a larger machine network. Layout must separate analog inputs and power paths from switching-node signals to preserve control accuracy.
推薦
Medical and Diagnostic Instrumentation
The STM32F091CCT6 can serve as the control processor in compact diagnostic or monitoring instruments that require deterministic embedded control and mixed analog functions. Its 12-bit ADC supports acquisition from sensor front ends, its 10-bit DAC supports stimulus generation or offset control, and the 48 MHz Cortex-M0 core executes control and communication tasks. A 2.0 V to 3.6 V operating range simplifies integration with 3.3 V systems. For sensitive analog work, the PCB should use controlled grounding, short analog traces, appropriate reference design, and isolation or filtering defined by the complete measurement chain.
推薦
IoT and Connected Sensor Hubs
The STM32F091CCT6 works as a local hub in connected sensor systems because it combines a 48 MHz Cortex-M0 processor, 256 KB Flash, 12 timers, ADC, DAC, and CAN in one 48-LQFP device. The microcontroller can preprocess sensor measurements, manage local timing, and forward data through a CAN peripheral connection. Its integrated analog converters reduce the need for separate components in compact designs. Firmware should include watchdog and communications-error recovery, while the hardware design should follow the manufacturer decoupling and clock recommendations to prevent long-term reliability problems.
推薦
LED and Lighting Control Modules
The STM32F091CCT6 is appropriate for LED and lighting controllers because 12 timers support multiple PWM outputs and the 48 MHz core provides deterministic timing for dimming and effects. The 12-bit ADC can monitor a current-sense or ambient-light signal, while CAN enables centralized control across multiple lighting modules. Its 256 KB Flash can hold control tables, calibration coefficients, and communication handlers. The 48-LQFP package keeps the controller compact, although designers should confirm timer-channel assignments in the datasheet and isolate LED switching traces from sensitive analog measurements.
推薦
Battery-Powered Embedded Control
The STM32F091CCT6 can serve as the supervisory controller in a battery-powered embedded product that combines sensing, timing, and CAN communications. Its Cortex-M0 architecture is designed for efficient embedded control, and the 2.0 V to 3.6 V range supports low-voltage power systems. The ADC can monitor battery or system conditions, the DAC can support controlled analog output, and the 12 timers can manage periodic measurements. Low-power behavior must be configured in firmware using the manufacturer low-power guidance, while the PCB should minimize leakage paths and provide local supply bypass capacitance.

主要差異化特點
- Combines 48 MHz processing with an integrated CAN controller (對比STM32F091CCT7)
- Provides a broad set of mixed-signal peripherals in the same device (對比STM32F091CCU6)
- Maintains the same compact 48-LQFP footprint across identified family alternatives (對比STM32F091CCT7)
設計說明
Place the required decoupling capacitors directly beside the STM32F091CCT6 supply pins, with short ground returns and a clear separation between noisy digital paths and analog inputs. Follow the manufacturer reference schematic and pin-description table for capacitor selection and placement. Keep the 48-LQFP escape routes short enough to preserve signal integrity while avoiding acute angles and long parallel spans between high-speed clock or communications routes.
Route ADC and DAC signals away from CAN, clock, and switching-power nodes, and use a continuous ground reference beneath sensitive analog circuitry. The 12-bit ADC may require filtering and careful reference-return routing rather than simply a short signal trace. Validate the completed layout for crosstalk, ground bounce, and reference stability using measurements from a production-intent PCB.
Do not assume that two STM32F091CC orderable suffixes are interchangeable in every environment. The STM32F091CCT7 and STM32F091CCU6 retain the same core frequency, Flash capacity, and 48-LQFP footprint, but their grade codes may represent different environmental or qualification requirements. Confirm the complete ordering code, temperature range, qualification status, pin functions, and firmware assumptions before substitution.
Design the power tree for a 2.0 V to 3.6 V MCU operating range and ensure every connected peripheral shares compatible logic levels. Check supply tolerance, startup sequencing, reset behavior, and maximum input voltage for every connected device. Place bulk and local bypass capacitance according to the manufacturer reference design and verify the power rail under CAN activity and maximum timer switching load.
