On-chip peripherals include DMA, a watchdog timer, PWM-capable timers, a temperature sensor, and POR/PVD/PDR reset management. ## Package and power — 36-VFQFPN with exposed pad for compact boards Housed in a 36-VFQFPN (6x6 mm) with an exposed thermal pad, this MCU suits space-constrained PCBs where heat spreading matters. The 26 I/O lines in this package count are enough for a keypad, a small character LCD, and a few sensor inputs — but if you need more than 26 GPIO, step up to the 48-pin or 64-pin STM32F101 variants. For dual-sourcing or a higher-density drop-in, the STM32F101 family shares the same pinout across Flash density options in the same package — a 32 KB or 64 KB sibling in the 36-VFQFPN footprint will fit the same board with a firmware update.","metaTitle":"STM32F101T4U6ATR ARM Cortex-M3 MCU, 36 MHz, 16 KB Flash","metaDescription":"STMicroelectronics STM32F101T4U6ATR 32-bit MCU, 36 MHz Cortex-M3, 16 KB Flash, 4 KB SRAM, 26 I/O, -40 to 85°C, 36-VFQFPN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"36MHz","Series":"STM32F1","Package":"Tape & Reel (TR)","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, PDR, POR, PVD, PWM, Temp Sensor, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"26","Core Processor":"ARM® Cortex®-M3","Package / Case":"36-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 10x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F101","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"36-VFQFPN (6x6)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5639","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e53b7292cece77c442cc4dfa04048599.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F101T4U6ATR/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F101T4U6ATR pin-compatible with STM32F101T6U6?","answer":"The STM32F101 family uses a common pinout across Flash density options in the same package footprint.
