32 MHz Cortex-M0+ in a 14-TSSOP — ultra-low-power foundation
It runs at 32 MHz, with 16 KB of Flash and 2 KB of SRAM, plus 512 bytes of embedded EEPROM for configuration data that survives power loss without external storage. The 14-TSSOP package with 11 I/O keeps the board footprint small, making this a fit for space-constrained, battery-powered designs like sensor nodes, portable instruments, and IoT edge devices.
The integrated brown-out detect and POR keep the core from misbehaving during ramp-up or sag.
Industrial temp range and peripherals
On-chip peripherals include a 4-channel 12-bit ADC, DMA, PWM timers, and a watchdog timer.
Active lifecycle — no LTB concern
STMicroelectronics lists the STM32L011D4P7 as Active. There is no announced last-time-buy or end-of-life notice. The base product number STM32L011 covers several Flash and package variants, so production volume across the family supports stable supply.
