Product details
Overview
STM32F103RCY6CTR from STMicroelectronics is a high-density performance-line Arm® Cortex®-M3 microcontroller featuring 256 KB Flash, 48 KB SRAM, 72 MHz CPU frequency, USB 2.0 full-speed and CAN 2.0B interfaces, and operates across -40°C to +85°C industrial temperature range. It integrates three 12-bit ADCs (21 channels), two 12-bit DACs, 11 timers including motor-control PWM units, and supports real-time control in motor drives and industrial PLCs.
For engineers reviewing the STM32F103RCY6CTR datasheet, STM32F103RCY6CTR pinout, STM32F103RCY6CTR application, or STM32F103RCY6CTR equivalent, key selection criteria include Flash/SRAM size, USB+CAN dual-interface capability, 64-pin WLCSP package footprint, and support for deterministic real-time execution via NVIC and SysTick timer.
Technical Context
This MCU implements an Arm Cortex-M3 core with Harvard architecture, single-cycle multiplication, hardware divide, and nested vectored interrupt controller (NVIC) supporting up to 68 maskable interrupts. Memory subsystem includes 256 KB on-chip Flash with error correction, 48 KB SRAM, and FSMC supporting NOR/PSRAM/NAND external memory expansion.
Peripheral integration centers on real-time I/O control: dual 12-bit DACs with DMA-triggered waveform generation, triple 12-bit ADCs with triple-sample-and-hold and temperature sensor input, and dedicated motor-control timers with dead-time insertion and emergency stop inputs - all synchronized via shared APB bus matrix and DMA request routing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103RCT6 | LQFP64 package (10 × 10 mm), higher thermal mass, easier rework; identical electrical specs and peripheral set | Suitable for prototyping, lab equipment, and medium-volume industrial panels where board space is less constrained | Select when manual soldering, in-circuit debugging, or thermal dissipation >150 mW is required |
| STM32F103VCT6 | LQFP100 package, adds 32 additional GPIOs and 2 more ADC channels; Flash/SRAM unchanged | Required for designs needing >51 I/Os or simultaneous analog acquisition from >21 channels (e.g., multi-axis motion controllers) | Choose only if pin count or ADC channel expansion justifies larger footprint and cost increase |
Compared with STM32F103RCT6, the RCY6CTR offers identical functionality in a 60% smaller footprint but requires micro-via PCB design and reflow-only assembly; versus STM32F103VCT6, it trades I/O scalability for compactness and lower system-level BOM cost in space-limited edge nodes.

FAQ
What is the maximum operating frequency and associated power consumption in Run mode?
The STM32F103RCY6CTR achieves 72 MHz CPU frequency with typical active current of 36 mA at 72 MHz and 3.3 V supply when executing code from Flash. This value assumes all peripherals disabled except core and SysTick; adding USB or ADC increases consumption by 12–18 mA depending on activity.
Does this part support external memory expansion, and what interfaces are available?
Yes - the Flexible Static Memory Controller (FSMC) supports external NOR, PSRAM, NAND, and CompactFlash memories via dedicated address/data bus and control signals. It provides configurable timing parameters (read/write setup/hold/wait) and four chip-select outputs, enabling direct connection without external logic.
How many ADC channels are accessible in the WLCSP64 package, and are they multiplexed?
The WLCSP64 exposes 16 ADC input channels (10 from PA/PB ports, 6 from PC/PH), all mapped to ADC1 and ADC2. Channels are fully multiplexed - any enabled channel can be selected per conversion sequence, and triple ADC interleaving allows simultaneous sampling across all three converters.
Is USB functionality self-powered, and does it require an external PHY?
No external PHY is required: the integrated USB 2.0 full-speed transceiver includes differential drivers, line termination, and pull-up resistor on DP. The device operates in self-powered mode only - VBUS detection is not implemented, so host-powered enumeration must be managed externally via software-controlled VBUS sensing circuitry.
