On-chip peripherals include a 12-bit ADC with 16 channels, a 12-bit DAC, DMA, a real-time LCD driver, and a USB interface. ## Package and assembly considerations for the 64-TFBGA The supplier device package is 64-TFBGA (5x5). The surface-mount footprint is compatible with standard BGA land patterns for a 64-ball, 0.5 mm pitch array.","metaTitle":"STM32L053R8H6 STM32L0 MCU, ARM Cortex-M0+, 32 MHz","metaDescription":"STMicroelectronics STM32L053R8H6 32-bit MCU with ARM Cortex-M0+ core at 32 MHz, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, industrial temp -40°C to 85°C, 64-TFBGA","metaKeywords":null},"attributes":{"series":"STM32L0","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"32MHz","Series":"STM32L0","Package":"Tray","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"2K x 8","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"51","Core Processor":"ARM® Cortex®-M0+","Package / Case":"64-TFBGA","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L053","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"64-TFBGA (5x5)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.1300","priceTiers":[{"qty":1,"price":"$5.13000","currency":"USD"},{"qty":10,"price":"$4.60600","currency":"USD"},{"qty":25,"price":"$4.35440","currency":"USD"},{"qty":80,"price":"$3.77375","currency":"USD"},{"qty":230,"price":"$3.58022","currency":"USD"},{"qty":640,"price":"$3.21253","currency":"USD"},{"qty":1280,"price":"$2.70937","currency":"USD"},{"qty":2560,"price":"$2.57390","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/53e74e23276668cce10b5d6ab1fe2ff9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L053R8H6/alternatives.json"},"ai":{"faq":[{"question":"What are the main differences between STM32L053R8H6 and STM32L053R8T6?","answer":"The STM32L053R8H6 is packaged in a 64-TFBGA (5x5 mm), while the STM32L053R8T6 uses an LQFP-64 package.
