That buys you a tiny footprint — roughly 2.5 mm square — but it also means the part is not hand-solderable and needs a proper SMT reflow profile with a stencil. The part includes DMA, I²S, POR, PWM, and a WDT, plus a 10-channel 12-bit ADC. ## 48 MHz clock and 4 KB SRAM — the firmware headroom check At 48 MHz the Cortex-M0 executes most instructions in one or two cycles. The 4 KB SRAM limits buffering for moderate applications. ## WLCSP assembly — what the rework tech needs to know The 25-WLCSP is a direct-solder-attach package with no plastic overmould. The solder balls are the package body. MSL is typically MSL 1 for ST's WLCSP parts, but verify the date code on the reel — if the moisture barrier bag has been open beyond the floor life, a bake at 125°C for 48 hours is required before reflow. The 0.4 mm pitch means a laser-cut stencil with 0.25 mm aperture is typical. After rework, X-ray the joints; the hidden balls under the die are not visually inspectable.","metaTitle":"STM32F038E6Y6TR ARM Cortex-M0 MCU, 48 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32F038E6Y6TR 32-bit ARM Cortex-M0 MCU, 48 MHz core, 32 KB Flash, 4 KB SRAM, 1.65-3.6 V supply, -40 to 85°C, 25-WLCSP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"48MHz","Series":"STM32F0","Package":"Tape & Reel (TR)","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":"19","Core Processor":"ARM® Cortex®-M0","Package / Case":"25-UFBGA, WLCSP","Product Status":"Active","Data Converters":"A/D 10x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F038","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"25-WLCSP","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3606","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/69415cebd80a008abb16ba448d62e2fa.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F038E6Y6TR/alternatives.json"},"ai":{"faq":[{"question":"Does STM32F038E6Y6TR have I2C and SPI interfaces?","answer":"Yes.
