Active production, 32 MHz Cortex-M0+ with USB and analog
The STM32L052C8T6D is an STMicroelectronics 32-bit MCU built around the ARM Cortex-M0+ core running at 32 MHz, part of the STM32L0 ultra-low-power series.
Memory map and peripheral headroom for sensor-node designs
The 2 KB EEPROM space holds configuration parameters and calibration constants that survive power cycles without wear-leveling overhead. The 10-channel 12-bit ADC and single 12-bit DAC cover analog front-end tasks — think battery monitoring, thermistor readout, or set-point generation — without an external converter.
37 I/O and 48-LQFP package — board integration
The 48-LQFP (7x7 mm) package provides 37 general-purpose I/O lines, enough for a keypad matrix, segment LCD, or parallel sensor array alongside the serial interfaces. Surface-mount assembly with standard reflow profiles; the 0.5 mm pitch is inspectable under a microscope and reworkable with hot air.
