HMI Dev Kit for Solar-Management Apps Features High-Res Display
Built around Microchip’s 1-GHz SAMA7D65 MPU, the Solar Monitor HMI Reference Design is a rugged, low-risk path from prototype to field-deployed solar-management solution for utility-grade operator panels, mobile maintenance kiosks, and edge-analytics systems.
Packaged in a compact 14- × 14-mm BGA with an automotive-grade roadmap, the reference design includes a bright 10-in. LVDS capacitive touchscreen driven by the ATMXT1066TD touchscreen controller. It can deliver real-time solar-farm insights — string currents, inverter output, battery-storage levels, and weather data — on a single high-resolution dashboard.
The reference design includes dual Gigabit Ethernet with IEEE-1588/TSN, multiple CAN-FD and I3C channels and 3× I2S, PDM mic input, SPDIF, and 4× stereo ASRCs.
It also features integrated hardware crypto and TrustZone security (AES/TDES/SHA/RSA/ECC), SRAM PUF, on‑the‑fly encryption/decryption, and OTP key storage, which help safeguard connected‑home credentials and firmware. They also allow developers to connect securely to SCADA networks, tracker controllers, and BMS units without external gateways.
The system’s Flexible Software Stack gives designers the choice between bare‑metal MPLAB Harmony and embedded Linux. Choose bare‑metal Harmony for instant boot, deterministic control, and minimal memory, or move to a full embedded‑Linux distro when the need arises for nrich networking, containers, and field upgradability. Both paths are fully supported on the same hardware.
Those systems work with the royalty-free Microchip Graphics Suite (MGS), which enables drag-and-drop GUI customization and effortless re-targeting to embedded Linux when cloud analytics or containerized services are required.
