Typical firmware for a UART-to-I2C bridge, a simple PWM fan controller, or a single-zone temperature monitor fits comfortably. If the project needs a USB stack, a real-time OS kernel, or over-the-air update staging, the Flash budget gets tight — the pin-compatible STM32F031C6T6TR doubles the Flash to 32 KB and is worth evaluating before the layout locks. The 4 KB SRAM (4K x 8) supports moderate data buffers and a few stack frames; DMA offloads peripheral transfers without consuming CPU cycles. ## 48-LQFP package — footprint and routing Housed in a 48-LQFP (7x7 mm) with 0.5 mm pitch, the STM32F031C4T6TR uses a standard JEDEC footprint that routes easily on two-layer boards. The 39 I/Os are distributed around all four sides; the supply pins (VDD, VDDA, VSS) sit on opposite corners, so a 100 nF ceramic per supply pair plus a bulk 4.7 µF on the main 3.3 V rail covers decoupling. The exposed pad is not present on this package — thermal dissipation relies on the leadframe and airflow, adequate for the sub-100 mA typical draw at 48 MHz. The base product number STM32F031 spans multiple Flash and SRAM density variants in the same package, so a firmware-only migration to a higher-density sibling (e.g., STM32F031C6T6TR) is possible without a board spin. ## Sourcing posture As an active STM32 part, the STM32F031C4T6TR is available through the independent distribution channel. For volume production, a firm lead time is quoted per order — no allocation constraints are currently reported on this density tier.","metaTitle":"STM32F031C4T6TR ARM Cortex-M0 MCU, 48 MHz, 16 KB Flash","metaDescription":"STMicroelectronics STM32F031C4T6TR 32-bit MCU: ARM Cortex-M0 at 48 MHz, 16 KB Flash, 4 KB SRAM, 13-ch 12-bit ADC, 39 I/O, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"STM32F0","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"48MHz","Series":"STM32F0","Package":"Tape & Reel (TR) Cut Tape (CT)","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I2S, POR, PWM, WDT","Connectivity":"I2C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"39","Core Processor":"ARM® Cortex®-M0","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 13x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F031","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3000","priceTiers":[{"qty":1,"price":"$3.30000","currency":"USD"},{"qty":10,"price":"$2.96700","currency":"USD"},{"qty":25,"price":"$2.80480","currency":"USD"},{"qty":100,"price":"$2.43100","currency":"USD"},{"qty":250,"price":"$2.30628","currency":"USD"},{"qty":500,"price":"$2.06942","currency":"USD"},{"qty":1000,"price":"$1.74530","currency":"USD"},{"qty":2400,"price":"$1.65803","currency":"USD"},{"qty":4800,"price":"$1.59570","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7127f169a82fed95ea2bf9d385a9c5f9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F031C4T6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the flash size of STM32F031C4T6TR?","answer":"The STM32F031C4T6TR has 16 KB of Flash program memory (16K x 8), which is the firmware capacity limit for this variant."},{"question":"Is STM32F031C4T6TR equivalent to STM32F031C6T6TR?","answer":"The STM32F031C6T6TR is a pin-compatible sibling in the same STM32F031 base series with double the Flash (32 KB vs 16 KB).
