On-chip peripherals include a 12-bit ADC with 10 channels, a single 12-bit DAC, and a full-speed USB 2.0 interface, plus the usual I2C, SPI, and USART serial ports. ## Memory sizing and the firmware budget The 2 KB EEPROM is a genuine separate array — not emulated in Flash — so you can write single bytes without sector-erase overhead. If your firmware image plus data logging exceeds 64 KB, you step up to the STM32L073 series (192 KB Flash) or move to the STM32L1 family, which offers up to 512 KB Flash at the same 32 MHz core speed. The ROHS3 compliance covers EU and global environmental requirements without exemptions.","metaTitle":"STM32L052K8T7 ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L052K8T7 32-bit MCU with ARM Cortex-M0+ core, 32 MHz speed, 64 KB Flash, 8 KB RAM, 2 KB EEPROM.

The L052 adds a full-speed USB interface and a 12-bit DAC that the L051 lacks. Firmware must be updated to enable those peripherals, and the active current draw is slightly higher when USB is enabled."},{"question":"Is STM32L052K8T7 suitable for battery-powered devices?","answer":"Yes. The Cortex-M0+ core is designed for ultra-low-power operation, and the supply range down to 1.65 V lets it run directly from two alkaline cells or a single Li-ion battery without an external regulator. The separate 2 KB EEPROM avoids Flash wear for frequent data logging, further extending system life."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L052K8T7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L052K8T7 when reusing this data.
