On-chip peripherals include a USB 2.0 full-speed interface, an I2S audio bus, and a segment LCD driver — features that consolidate BOM count in portable instruments, smart meters, and IoT edge nodes. The 48-LQFP package (7x7 mm body) is a common footprint for mid-density MCUs, and the 37 available I/O pins leave room for a parallel LCD bus, keypad matrix, and sensor interfaces alongside the USB and I2S blocks.","metaTitle":"STMicroelectronics STM32L053C8T7 MCU, 32-bit Cortex-M0+","metaDescription":"STMicroelectronics STM32L053C8T7 32-bit ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, -40 to 105 °C, 48-LQFP.","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":"37","Core Processor":"ARM® Cortex®-M0+","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 10x12b; 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 ~ 105°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.3400","priceTiers":[{"qty":1,"price":"$5.34000","currency":"USD"},{"qty":10,"price":"$4.79500","currency":"USD"},{"qty":25,"price":"$4.53320","currency":"USD"},{"qty":80,"price":"$3.92875","currency":"USD"},{"qty":250,"price":"$3.72728","currency":"USD"},{"qty":500,"price":"$3.34448","currency":"USD"},{"qty":1000,"price":"$2.82065","currency":"USD"},{"qty":2500,"price":"$2.67962","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/53e74e23276668cce10b5d6ab1fe2ff9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L053C8T7/alternatives.json"},"ai":{"faq":[{"question":"What are the key differences between STM32L053C8T7 and STM32L053C8T6?","answer":"The STM32L053C8T7 and STM32L053C8T6 share the same die, Flash and RAM sizes, and peripheral set.

If your firmware does not rely on those peripherals, the pinout and memory map are compatible across the STM32L0 value-line family, so a drop-in replacement is feasible with a firmware update.
