5 Microcontroller (R7FA4M1AB3CFM#AA0)
The UNO R4 Minima is based on the 32-bit RA4M1 series microcontroller, R7FA4M1AB3CFM#AA0, from Renesas,
which uses a 48 MHz Arm® Cortex®-M4 microprocessor with a floating point unit (FPU).
On the UNO R4 Minima, the operating voltage is fixed at 5 V to be fully retro compatible with shields, accessories &
circuits originally designed for older UNO revisions.
The R7FA4M1AB3CFM#AA0 features:
256 kB flash / 32 kB SRAM / 8 kB data flash (EEPROM)
Real-time Clock (RTC)
4x Direct Memory Access Controller (DMAC)
up to 14-bit ADC
up to 12-bit DAC
OPAMP
1x CAN bus
