STMicroelectronics ST7570 | Demoboard EVALKITST7570-1

Beschreibung

The ST7570 is a powerful power line networking system-on-chip. It combines a high-performance PHY processor core and a protocol controller core with a fully integrated analog front end (AFE) and line driver.The ST7570 features allow the most costeffective, single-chip power line communication solution based on IEC61334-5-1 S-FSK standard.
