ARM Cortex-M0+ core with 64 KB flash and on-chip EEPROM
The STM32L062K8T6 is a 32-bit microcontroller built around the ARM Cortex-M0+ core running at 32 MHz — the entry-level 32-bit architecture that balances code density and power draw for battery-operated and always-on sensing applications. Its 64 KB flash program memory pairs with 8 KB SRAM and a separate 2 KB EEPROM block, which is unusual for this class: the EEPROM stores calibration constants and configuration data without wearing the flash, and it survives 100,000 write cycles typical per the STM32L0 family datasheet.
Peripheral set and I/O allocation in a 32-pin LQFP
The 32-LQFP package (7x7 mm body) exposes 27 general-purpose I/O pins — only five pins are consumed by power and ground, which is a high utilization ratio for this pin count. The fine-pitch 0.8 mm leads are hand-solderable and route easily on a two-layer board. IrDA support is available for wireless optical links in noisy industrial environments.
Temperature range and deployment context
It is ROHS3 compliant and suitable for new designs targeting EU markets.
