80 MHz RXv2 core with 256 KB Flash — what this MCU brings to the BOM
The R5F524UBAGFP#30: The 100-LQFP package (14x14 mm body) gives access to 79 I/O lines, enough to drive a parallel LCD interface, a keypad matrix, and a handful of discrete sensors without external GPIO expanders. On-chip peripherals include DMA, LVD, POR, PWM, and WDT — the set covers the usual watchdog, brown-out, and pulse-width modulation needs for motor-drive or power-conversion loops.
Industrial temperature and connectivity — where this part fits
Rated for -40°C to 105°C, this MCU is specced for the industrial temperature band. The connectivity block includes CANbus, I²C, SCI, and SPI. The internal oscillator eliminates the external crystal for applications that can tolerate a few percent frequency drift over temperature, but the device also supports an external clock source when tighter timing is needed. The 20-channel 12-bit ADC and dual 8-bit DAC handle analog front-end tasks like current-sense feedback or setpoint generation. For a three-phase motor drive, the 12-bit ADC can sample two phase currents and the DC-link voltage in one conversion sequence; the DACs can output a reference or a compensation signal.
