Key characteristics of the photovoltaic module's main chip include:

• High operating frequency of 200 MHz

• Reliable Flash memory supporting ECC (Error Correction Code) and encryption.

• Large SRAM capacity of 196 KB with strong reliability, supporting parity checks and ECC

• Extensive timer resources with high precision: 1 high-precision timer (125 ps accuracy), 3 advanced timers (5 ns accuracy), and 10 general-purpose timers (5 ns or 10 ns accuracy)

• Three U(S)ART TX/RX channels supporting full pin mapping for easy customer pin assignment. 

• CAN-FD pins support full pin mapping for flexible customer pin allocation.

• Fast ADC sampling rate of 4.7 Msps, supporting both single-ended and differential modes.

• High-performance analog operational amplifiers supporting single-ended and differential modes with GBW of 40 MHz, SR of 20 V/μs (single-ended mode), and SR of 40 V/μs (differential mode) 

• Cordic supports both integer and floating-point calculations.

• Strong EFT performance with power supply rated at +/-4 kV, Level A, and I/O at +/-2 V, Level A

• Robust ESD performance with power/ground at +/-10 kV, Level A, and I/O at +/-1.5 kV, Level A
