Nine 12-bit ADC channels let the part read multiple current-sense resistors, voltage taps, and temperature sensors without external muxing. The single 12-bit DAC can output a setpoint or analog reference directly. It is not nearing end-of-life and no last-time-buy notification has been issued. For a production BOM, this means no urgency to qualify a replacement or stockpile inventory. ## 48-LQFP footprint — land pattern and routing notes The 48-LQFP package with a 7x7 mm body uses a 0.5 mm pitch. The exposed pad is not present on this LQFP variant, so thermal dissipation relies on the leadframe and board copper. Decoupling should follow the STM32F3 reference design: one 100 nF ceramic per VDD pair plus a 4.7 µF bulk on the main rail.","metaTitle":"STM32F302CBT7 STM32F3 ARM Cortex-M4 MCU, 72 MHz","metaDescription":"STM32F302CBT7 32-bit ARM Cortex-M4 MCU from STMicroelectronics: 72 MHz core, 128 KB Flash, 32 KB SRAM, 9x12-bit ADC, 1x12-bit DAC, 48-LQFP, -40 to 105°C.","metaKeywords":null},"attributes":{"series":"STM32F3","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F3","Package":"Tray","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"37","Core Processor":"ARM® Cortex®-M4","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 9x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F302","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.3700","priceTiers":[{"qty":1,"price":"$6.37000","currency":"USD"},{"qty":10,"price":"$5.75000","currency":"USD"},{"qty":25,"price":"$5.48280","currency":"USD"},{"qty":80,"price":"$4.76075","currency":"USD"},{"qty":250,"price":"$4.54680","currency":"USD"},{"qty":500,"price":"$4.14560","currency":"USD"},{"qty":1000,"price":"$3.61068","currency":"USD"},{"qty":2500,"price":"$3.47696","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/abc7277dd36d539fcf2d3c46eff57822.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F302CBT7/alternatives.json"},"ai":{"faq":[{"question":"What are the exact specifications of STM32F302CBT7 (core, speed, flash, RAM, package)?","answer":"The package is a 48-pin LQFP with a 7x7 mm body.
