The 11 general-purpose I/O lines are enough for a few sensor inputs, a serial bus, and a PWM output for a small motor or indicator. ## Industrial temperature grade and active lifecycle ST lists the product status as Active, so there is no near-term last-time-buy or EOL risk for production planning. The ROHS3 compliance simplifies EU and global regulatory acceptance. ## Connectivity and peripherals for a compact control loop A 4-channel 12-bit ADC handles analog sensor inputs without an external converter.","metaTitle":"STM32L021D4P6 STM32L0 ARM Cortex-M0+ MCU, 32 MHz","metaDescription":"STMicroelectronics STM32L021D4P6 32-bit MCU, ARM Cortex-M0+ at 32 MHz, 16 KB Flash, 2 KB SRAM, 512 B EEPROM, 14-TSSOP, -40 to 85°C.
