STM8L152 + STPM10: Basis of modular plug-and-measure single-phase
electricity meter solution
The STM8L152 and STPM10 chips from STMicroelectronics are designed to form the basis of a cost-effective
single-phase electricity meter solution.
The STPM10 metrology IC accurately measures the energy, voltage and current of the target.
The STM8L152 8-bit microcontroller efficiently and securely stores, displays, controls and transfers the measurements.
The scalability of this platform (extendable with the STM32L, STPMx) and the flexible connectivity (SPI, External
memories, UART, I2C) gives driving capability for a large set of periphe
