192 KB Flash, 20 KB RAM, 6 KB EEPROM — memory fit for a sensor-node firmware
The STM32L083RZH6: It carries 192 KB of Flash program memory, 20 KB of SRAM, and a separate 6 KB EEPROM block.
With 51 general-purpose I/Os, this MCU can handle a mix of digital sensors, keypad scanning, and display segment control. The data converter block provides 16-channel 12-bit ADC and two 12-bit DAC channels for analog front-end tasks.
The base product number is STM32L083, which covers the family of density and package variants.
Packaging and assembly note
The 64-TFBGA (5x5 mm) package has a 0.5 mm ball pitch typical of this class — the PCB layout must route the balls with a via-in-pad or microvia strategy for dense designs.
