The 0.4 mm or 0.5 mm ball pitch typical of WLCSP means the escape routing uses microvias or fine-line traces. The 36 I/O count leaves room for a sensor array plus a display or UART bridge. Peripherals include I²C, SPI, UART/USART, USB OTG, SDIO, I²S, and IrDA, plus a 10-channel 12-bit ADC. The internal oscillator trims the BOM by one external crystal for many applications.","metaTitle":"STM32F401CEY6TR STM32F4 ARM Cortex-M4 MCU, 84 MHz","metaDescription":"STM32F401CEY6TR 32-bit ARM Cortex-M4 MCU at 84 MHz with 512 KB Flash and 96 KB SRAM in a 49-WLCSP package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"84MHz","Series":"STM32F4","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"96K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SDIO, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"36","Core Processor":"ARM® Cortex®-M4","Package / Case":"49-UFBGA, WLCSP","Product Status":"Active","Data Converters":"A/D 10x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F401","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"49-WLCSP","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.0552","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c1395acb0fdce6474233414430f990ad.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F401CEY6TR/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F401CEY6TR a replacement for STM32F401CEY6?","answer":"The base product number is STM32F401, and the suffix 'TR' typically indicates Tape & Reel packaging.
