New GD32L233 Series is based on Cortex®-M23 and is manufactured on the 40nm
Ultra-Low Power Process for Energy Saving Application.
The GD32L233 series of MCUs are available (Nov.2021) in package:
The official documentation is here.

Main characteristics

System frequency of up to 64MHz
64KB to 256KB embedded eFlash
16KB to 32KB SRAM
*** Power and consumption
The GD32L233 operates from 1.7V to 3.6V and supports a battery (Vbat) power supply.
The newly designed power management unit provides up to six low-power modes, including partial sleep, deep sleep, external wake-up, etc.
The deep-sleep current is reduced to 2µA, with the wake-up time achieving less than 10µs.
The standby current is as low as 0.4µA.
Under the maximum frequency and full-speed active mode, the power consumption is only 66µA/MHz, which proves excellent energy efficiency.
Flexible power supply modes can achieve lower average power consumption and extend battery life.
