The STMicroelectronics ST7590T is a fully integrated narrow-band OFDM power line networking system-on-chip designed for PRIME compliant smart metering and smart grid applications. It features a high-performing DSP engine with embedded firmware for Orthogonal Frequency Division Multiplexing (OFDM) modulation.
Key features include 96 sub-carriers in the CENELEC A band, programmable modulations (BDPSK, QDPSK, 8DPSK), and a programmable bit rate up to 128 kbps. The device also incorporates convolutional coding and Viterbi decoding, along with signal-to-noise ratio and channel quality estimation. A full PRIME compliant PHY is integrated.
On-chip peripherals include a host controller UART/SPI interface, I2C/SPI external data memory interface, and a high-speed SRAM controller. It also has an on-chip 128-bit AES encryption hardware block. The analog front end includes ADC and DAC, a high-sensitivity receiver, and a high-linearity transmitter with intelligent gain control.
The ST7590T is suitable for applications compliant with EN50065 and FCC part 15 specifications. It operates within a temperature range of -40 °C to +85 °C and is available in QFN48 and TQFP100 package options. The device supports 3.3 V or 5 V digital I/O supply and an 8 V to 18 V line driver power supply.
