The R5F52305AGFP#30 is a 32-bit RX230-series microcontroller built around the RXv2 core, clocked at 54 MHz. On-chip memory comprises 128 KB of program flash, 32 KB of SRAM, and a separate 8 KB data flash that serves as EEPROM emulation — enough headroom for a moderate control loop with a non-volatile parameter table.
Analog and peripheral complement
Twenty-four 12-bit ADC channels and two 12-bit DAC outputs are integrated — the ADC count alone covers multi-axis sensor feedback or a 16-channel analog input module with margin for diagnostics. The DACs can generate analog setpoints or bias voltages without external converters. With 83 general-purpose I/O in the 100-LQFP package, this part suits a control board that needs parallel bus expansion alongside serial interfaces.
