STM32G0B1KCT6 - 64MHz Cortex-M0+ MCU | STMicroelectronics
MPN: STM32G0B1KCT6 ✓ نشطSTM32G0B1KCT6 نظرة عامة
A microcontroller is a programmable semiconductor that combines a CPU core, memory, and peripherals in one device. The STM32G0 belongs to the STM32G0 mainstream microcontroller family, where the Arm Cortex-M0+ RISC core provides compact, energy-efficient control for embedded products. Its combination of serial interfaces, analog converters, and general-purpose timers supports industrial controllers, communication equipment, access controls, and compact consumer devices.
The 256 KB Flash configuration provides room for application firmware, while 144 KB of RAM supports protocol buffers, data acquisition, and real-time control state. The six-USART configuration is especially useful for multi-port gateways, serial concentrators, programmable controllers, and equipment that must connect several external devices. The integrated ADC and DAC enable measurement and signal-generation functions without requiring separate analog devices.
The STM32G0 architecture targets efficient embedded control with a maximum core frequency of 64 MHz and a 1.7 V to 3.6 V supply range. The operating-temperature families associated with the STM32G0B1 xB, xC, and xE devices span options identified by STMicroelectronics as extending from -40 °C to 85 °C, 105 °C, or 125 °C. The exact temperature grade for this orderable part must be confirmed from its ordering information before deployment.
Typical uses include serial-to-Ethernet gateways, motor and valve controllers, access-control readers, programmable logic controllers, building automation controllers, and low-cost sensor-hub designs. Engineers can use the USARTs for downstream and upstream links, the ADC for analog monitoring, the DAC for controlled outputs, and timers for periodic or capture-based operations.
PCB design should preserve a short return path for every supply pin and place decoupling capacitors close to the device. Confirm pin assignments, alternate functions, and debug connections against the STM32G0B1KC product documentation before routing a new board. This page combines the verified product characteristics, sourcing guidance, interface use cases, and design checks needed for initial component selection.

التطبيقات النموذجية
STM32G0B1KCT6 مناسب لـ 6 التطبيقs: Industrial Serial Gateway, Programmable Logic Controller, Access-Control Reader, Building Automation Controller, Sensor and Data-Acquisition Hub, Battery-Powered Instrumentation.
Industrial Serial Gateway
The STM32G0B1KCT6 fits an industrial serial gateway because its six USARTs can support multiple downstream devices while the 64 MHz Arm Cortex-M0+ core handles protocol conversion and local control. Its 144 KB of RAM provides useful capacity for frame buffering, while 256 KB of Flash accommodates gateway firmware, configuration data, and update logic. The 1.7 V to 3.6 V operating range supports compact low-voltage implementations. Designers should assign each serial channel according to the package pin table, isolate exposed connector interfaces where required, and use the integrated ADC for supervisory measurements rather than assuming automatic protection for external signals.

Programmable Logic Controller
The STM32G0B1KCT6 is well suited to compact PLC and machine-control modules because it combines a 64 MHz Cortex-M0+ core, timers, 256 KB of Flash, 144 KB of RAM, ADC, DAC, and serial communications in one 32-LQFP device. Timers can organize deterministic input scanning and output updates, while the ADC and DAC support analog process signals. Use a regulator and local bulk capacitance selected for the complete I/O power budget, and preserve the MCU ground connections from switching-output return currents to prevent timing or measurement errors.
موصى به
Access-Control Reader
The STM32G0B1KCT6 can manage access-control readers that combine credential input, status indication, communications, and local event handling. Its 144 KB of RAM is adequate for buffering credential and transaction records, while the six USARTs can support reader peripherals, host communication, and configuration or maintenance links. The 32-LQFP 7 x 7 mm footprint helps create compact reader electronics. Security-sensitive designs should implement authentication, key storage, and communication protection according to the product requirements rather than assuming that the presence of a general-purpose MCU provides a dedicated security boundary.
موصى به
Building Automation Controller
The STM32G0B1KCT6 supports building automation controllers that coordinate lighting, HVAC interfaces, sensors, and remote communications. Six USARTs allow multiple field-bus or service interfaces to coexist with an optional site controller, while the integrated ADC can monitor environmental or equipment analog signals. The 64 MHz core provides sufficient throughput for supervisory logic, while 144 KB of RAM supports protocol state and event queues. Place the MCU away from relay drivers and switching regulators, use a continuous ground plane, and validate timing margins under worst-case electrical noise and temperature conditions.
موصى به
Sensor and Data-Acquisition Hub
The STM32G0B1KCT6 is appropriate for compact sensor hubs that gather analog measurements and forward them over serial links. Its integrated ADC reduces the need for a separate converter in straightforward measurement systems, while the DAC can generate reference or excitation signals where appropriate. The 256 KB of Flash holds configuration, calibration, and application firmware, and 144 KB of RAM can hold sampled batches. Engineers should calculate conversion and acquisition timing from the operating configuration, ensure signal levels remain within the selected peripheral limits, and use short, quiet analog routing where the hub also includes switching circuitry.
موصى به
Battery-Powered Instrumentation
The STM32G0B1KCT6 can serve as the control device in low-power instrumentation because it accepts a 1.7 V to 3.6 V supply and provides substantial memory and peripheral integration in a compact 32-LQFP package. The MCU can manage sensor sampling, local display or logging, and serial configuration while retaining enough Flash for application firmware and RAM for acquisition buffers. Actual battery life depends on the selected operating mode, peripheral activity, regulator efficiency, and sleep hardware configuration. Validate the complete power budget rather than inferring consumption from the maximum CPU frequency alone.

ملاحظات التصميم
Use the exact STM32G0B1KC power-supply guidance when assigning the 1.7 V to 3.6 V operating range. Place local decoupling capacitors directly beside the associated supply and ground pins, keep their ground returns short, and provide adequate bulk energy close to the device. Confirm regulator headroom during startup, peripheral transients, and the highest configured core frequency. The 64 MHz operating rate is a maximum capability, not a requirement for continuous full-speed operation.
Create the 32-LQFP 7 x 7 mm land pattern from the manufacturer package drawing rather than from a generic LQFP footprint. Verify pin 1 orientation, lead width, lead pitch, courtyard clearance, and the paste mask before fabrication. The six USARTs and mixed analog functions can create routing congestion, so assign pins early and preserve short access to SWD programming and power-reset signals.
Separate analog measurement paths from digital clocks, serial edges, relay drivers, and switching-converter connections. Keep the ADC and DAC routes away from high-current return paths, provide a continuous ground reference, and avoid routing communications signals across split ground boundaries. If switching circuitry shares the board, evaluate its conducted and radiated noise at the MCU pins rather than relying only on schematic separation.
Do not treat another STM32G0 member as a drop-in replacement solely because it uses an LQFP package. The STM32G0B1KCT6 combines a 32-pin 7 x 7 mm package, 256 KB Flash, 144 KB RAM, six USARTs, and specific peripheral assignments. A replacement can require a different land pattern, pin reassignment, firmware migration, peripheral redesign, or recalibration. Check every affected peripheral and software driver before approving a substitution.
