Product details

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.

Frequently asked questions

What is the operating voltage range of STM32L083RZH6?

Design engineers need to ensure the MCU's power supply matches the rest of the system.

Is STM32L083RZH6 compatible with ST-Link/V2?

Engineers and hobbyists need to know if their existing debug probe will work with this MCU for programming and debugging.

Where can I buy STM32L083RZH6 in small quantities?

Sourcing buyers and prototype developers often need small quantities from reliable distributors.

What is the lead time for STM32L083RZH6?

Production buyers must plan inventory and avoid supply chain delays.

Does STM32L083RZH6 have an alternative pin-compatible microcontroller?

Designers may need a drop-in replacement for availability or cost reasons without redesigning the PCB.

Is STM32L083RZH6 obsolete or active?

Brokers and buyers need lifecycle status to avoid end-of-life surprises and ensure long-term availability.
