Product details

The STM32L053R6H6: An LCD driver (up to 8x40 or 4x44 segments) is integrated.

Memory sizing and peripheral set for a BOM review

The 32 KB Flash and 8 KB SRAM are the exact figures a firmware engineer needs to budget the application code and runtime data. The 2 KB EEPROM saves an external serial EEPROM for calibration constants or configuration data that must survive a reset. Peripherals include brown-out detect, reset, DMA, I²S, PWM, watchdog timers, and a 12-bit ADC with 16 channels plus a 12-bit DAC.

Frequently asked questions

Is STM32L053R6H6 compatible with 3.3V logic?

Yes.

Does STM32L053R6H6 have a built-in LCD driver?

Yes, it integrates an LCD driver capable of driving up to 8x40 or 4x44 segments, eliminating an external display driver IC.

What is the closest pin-compatible alternative to STM32L053R6H6 in this component family?

The STM32L053R8H6 is a pin-compatible sibling with 64 KB Flash instead of 32 KB, otherwise identical in package, peripherals, and supply range. It is a direct drop-in replacement if more code space is needed.
