The Renesas R5F524TCAGFP#31 is a 32-bit RX24T microcontroller built around the RXv2 CPU core running at 80 MHz. It carries 384 KB of Flash program memory, 32 KB of RAM, and an additional 8 KB of data Flash (EEPROM emulation) — enough for a moderate sensorless field-oriented-control (FOC) firmware image plus parameter storage. The 22-channel 12-bit ADC and dual 8-bit DAC are sized for three-phase current sensing and analog reference generation in a single inverter stage.
384 KB Flash + 32 KB RAM — firmware headroom for FOC stacks
The 384 KB Flash (384K x 8) is sized for a full motor-control library with sensorless observer, PI current loops, and space-vector PWM, plus a communication stack. The 32 KB RAM handles the rotating frame variables and lookup tables without forcing external SRAM. The separate 8 KB EEPROM block (8K x 8) stores calibration constants and fault logs — no external serial EEPROM needed for the nonvolatile data that must survive power cycles.
22-channel 12-bit ADC — three-phase current sensing coverage
The 22 analog inputs on the 12-bit ADC let you sample all three phase currents, the DC-link voltage, and a temperature input in a single conversion sequence — no external mux. The two 8-bit DAC channels can provide analog reference voltages or offset trim signals without adding a separate DAC IC.
Renesas lists the R5F524TCAGFP#31 as Active.
