The GD32L235 is an ultra-low-power 32-bit Arm Cortex-M23 MCU from GigaDevice at 64MHz, with 64~128KB flash / 12~24KB SRAM. Power is very low: ~66µA/MHz run, 1.8µA deep-sleep (<2µs wake), 0.26µA standby, with low-power LPUART and LPTIMER for always-on tasks. It integrates a 12-bit ADC, DAC and two comparators, USB 2.0 FS and CAN 2.0, in LQFP/QFN and WLCSP25. Versus the cataloged GD32L233, the L235 adds CAN and richer peripherals — for smart locks, metering, wearables, and battery management.
