On-chip peripherals include I²C, SPI, USART, USB, and an LCD driver, making it a fit for metering, sensor nodes, and portable instruments that need to run from a coin cell or two AA batteries. ## Industrial temperature range — where it goes and where it doesn't It is not AEC-Q100 qualified, so it is not intended for under-hood automotive or engine-bay environments. The ROHS3 compliance is current. ## 48-LQFP rework and storage notes The 48-LQFP package is lead-free and hand-solderable with a fine-tip iron or hot-air station.","metaTitle":"STM32L053C8T6TR MCU, 32 MHz Cortex-M0+, 64 KB Flash, 48-LQFP","metaDescription":"STMicroelectronics STM32L053C8T6TR 32-bit MCU, ARM Cortex-M0+ at 32 MHz, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, 48-LQFP.

It is not a pin-compatible drop-in — the LQFP footprint differs. For a direct pin-compatible upgrade within the STM32L0 family, look at the STM32L073 series (larger Flash/RAM) in the same 48-LQFP package."},{"question":"How to program STM32L053C8T6TR?","answer":"The MCU supports SWD (Serial Wire Debug) through the standard ARM 4-pin interface. Boot from internal Flash with BOOT0 pulled low. ST's ST-Link programmer or any CMSIS-DAP probe works. The internal oscillator is enabled by default, so no external crystal is required for initial bring-up."},{"question":"What is the lead time for STM32L053C8T6TR?","answer":"As an active part with no LTB, it is generally available through the independent distribution channel, but current lead times vary by batch and demand."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L053C8T6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L053C8T6TR when reusing this data.
