Product details

32 MHz Cortex-M0+ with on-chip EEPROM — memory selection memo

The 48-LQFP package (7x7 mm) gives 37 I/Os, a 12-bit ADC with 10 channels, and a single 12-bit DAC. 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.

Frequently asked questions

What is the equivalent or replacement for STM32L053C8T6TR?

The STM32L151CBU6A is a functional peer from the STM32L1 series with a Cortex-M3 core, 32 MHz speed, and similar peripheral set, but it uses a different package (UFBGA) and has more ADC channels (16x12b) and two DACs. 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.

How to program STM32L053C8T6TR?

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.

What is the lead time for STM32L053C8T6TR?

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.
