On the peripheral side you get I²C, SPI, two UARTs, IrDA, and a USB 2.0 full-speed device interface. The 12-bit ADC has ten channels and there is one 12-bit DAC — enough for single-channel analog output or battery monitoring. ## 48-LQFP package and layout fit The 48-LQFP (7x7 mm body, 0.5 mm pitch) is a common footprint that hand-solders easily and fits two-layer boards without blind vias. 37 I/O are brought out, leaving enough pins for a parallel LCD data bus or a row of keypad inputs alongside the serial interfaces.","metaTitle":"STM32L052C6T6 ARM Cortex-M0+ MCU, 32MHz, 32KB Flash, 48-LQFP","metaDescription":"STM32L052C6T6 32-bit MCU with ARM Cortex-M0+ core, 32MHz, 32KB Flash, 8KB SRAM, 2KB EEPROM, 48-LQFP.

The main difference is the L052 adds a USB device interface and a DAC channel, so firmware and peripheral configuration must account for the extra blocks. It is a drop-in hardware replacement if the extra features are not used or are enabled in software."},{"question":"What is the difference between STM32L052C6T6 and STM32L053C6T6?","answer":"The STM32L053C6T6 is a higher-density variant in the same L0 family with 64 KB Flash and 8 KB SRAM versus the L052's 32 KB Flash and 8 KB SRAM. Both are pin-compatible in the 48-LQFP package, so the L053 is a firmware-upgrade path when the application outgrows the 32 KB Flash budget."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L052C6T6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L052C6T6 when reusing this data.
