Product details
Overview
STM32C011F4P6 from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller with 32 KB flash, 6 KB SRAM, 18 GPIOs (5 V-tolerant), 12-bit ADC (0.4 µs conversion), and dual USARTs supporting LIN/IrDA/ISO7816 - deployed in industrial sensor nodes, smart metering interfaces, and low-power IoT edge controllers.
For engineers reviewing the STM32C011F4P6 datasheet, STM32C011F4P6 pinout, STM32C011F4P6 application, or STM32C011F4P6 equivalent, key selection criteria include operating voltage range (2.0–3.6 V), -40°C to 125°C extended temperature grade, 48 MHz max CPU frequency, and TSSOP20 package compatibility with legacy PCB layouts.
Technical Context
The device integrates a Cortex-M0+ core with MPU, hardware parity-checked SRAM, and securable flash area for firmware integrity. It supports three low-power modes (Stop, Standby, Shutdown) with sub-µA retention current and wake-up via GPIO or RTC alarm.
Clock architecture includes 4–48 MHz HSE, 32 kHz LSE with calibration, and factory-trimmed 48 MHz HSI48 (±1 %) and 32 kHz LSI (±5 %). Peripheral interconnect uses DMAMUX for flexible channel mapping across 3 DMA streams.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32C011F6P6 | Same package and pinout; 64 KB flash, 8 KB SRAM - no change in peripheral count or clock specs | Required where firmware image size exceeds 32 KB or additional RAM buffers needed for protocol stacks | Select F6P6 only if code growth or data buffering demands exceed F4P6 capacity; identical qualification and toolchain support |
| STM32G031F8P6 | Higher-performance Cortex-M0+ (64 MHz), 64 KB flash, 8 KB SRAM, USB 2.0 FS - adds USB but removes LIN/IrDA support | Suitable for USB-CDC virtual COM port designs; not drop-in for ISO7816 or LIN-based metering | Choose G031F8P6 when USB connectivity is mandatory and LIN/IrDA are unused; verify USB power delivery and ESD layout changes |

FAQ
What is the maximum operating frequency and associated supply voltage range?
The STM32C011F4P6 operates at up to 48 MHz across its full 2.0–3.6 V supply range. At 2.0 V, the maximum guaranteed frequency is 24 MHz per electrical characteristics Table 23; full 48 MHz operation requires ≥2.7 V supply, validated per DS13866 Rev 5 Section 5.3.1.
Does this MCU support hardware encryption or secure boot features?
Yes - it holds SESIP3 and PSA Level 3 security certifications. The securable flash area enables readout protection (RDP) Level 1/2, and the embedded CRC unit accelerates firmware signature verification. However, it lacks dedicated AES or PKA accelerators found in higher-tier STM32 lines.
Can the 32 kHz LSE oscillator be calibrated, and what is its accuracy after calibration?
Yes - the LSE oscillator supports automatic calibration against the HSI48 clock source. Post-calibration accuracy improves from ±20 ppm (uncalibrated) to ±5 ppm over -40°C to +85°C, as specified in DS13866 Rev 5 Section 5.3.39 and Table 39.
Is the TSSOP20 package lead-free and RoHS-compliant?
Yes - the STM32C011F4P6 TSSOP20 package is ECOPACK2-compliant, meeting RoHS Directive 2011/65/EU and halogen-free requirements. Lead finish is matte tin, and JEDEC-standard reflow profiles apply per Section 6.4 of the datasheet.
