3 / 24 page ST7590 Device description Doc ID 18349 Rev 1 3/24 1 Device description ST7590 is available in two different package options: TQFP100 and QFN48. In the TQFP100 package option, order code ST7590T, the device comes with a dedicated FW implementing PRIME compliant PHY protocol Layer and a boot loader procedure that enables the IC to boot PRIME MAC, PRIME CL432 Convergence Layer and IEC 61334-4- 32 LLC Layer from an external Serial NV memory connected through SPI interface. In the QFN 48 package option, ST7590 comes with a dedicated FW implementing the full PRIME protocol stack (PHY, MAC and Convergence Layer), so without the need for external memories to run the protocol. The on-chip analog front end, featuring analog to digital and digital to analog conversion and automatic gain control, plus the integrated power amplifier delivering up to 1 Arms (typical) output current, makes the ST7590 the first complete Narrowband OFDM power line communication system-on-chip ideal for PRIME compliant applications. An HW 128-bit AES encryption block with PRIME compliant management is available on chip when secure communication is requested. Line coupling network design is also extremely simplified, leading to a very low cost Bill Of Material. Safe operations are assured while keeping power consumption and distortion levels very low, so making ST7590 an ideal platform for the most stringent application requirements and regulatory standards compliance.
