The 32 MHz CPU speed sets the throughput ceiling for control-loop tasks — a typical PID loop with sensor read, calculation, and PWM update completes in under 5 µs, leaving headroom for communication and housekeeping. ## Memory budget and peripheral fit for a mixed-signal BOM On-chip memory: 192 KB flash for program storage, 20 KB RAM for stack and data, and 8 KB data flash for non-volatile parameters — enough for a modest RTOS (FreeRTOS footprint ~6 KB) with a few hundred lines of application code and a small parameter table. The 10-channel ADC (8/10-bit resolution) and 2-channel DAC (8-bit) cover multi-sensor input with one analog output for trim or reference — no external ADC/DAC needed for a typical sensor-fusion or actuator-control board. Connectivity includes CSI (clocked serial interface), I²C, LINbus, and UART/USART — the LIN interface qualifies this MCU for automotive body-electronics nodes like window lift or mirror control. Peripherals: DMA offloads data movement from the CPU during ADC scan or UART reception; LVD (low-voltage detect) and POR (power-on reset) handle brownout and startup sequencing without an external supervisor IC. ## 48-HWQFN package — thermal pad and layout notes 34 GPIOs are available in this 48-pin package — about 70% of the pins are I/O; the rest are power, ground, oscillator, and reset. The 0.5 mm pitch demands a 4-layer board for full fan-out; a 2-layer board breaks out only the outer rows. ## Compliance and sourcing posture ROHS3 compliant — no exemptions for lead in solder or PBB/PBDE flame retardants; passes EU RoHS recast (2011/65/EU + 2015/863).","metaTitle":"R5F104GHANA#20 Renesas RL78/G14 MCU, 32 MHz, 192 KB Flash","metaDescription":"R5F104GHANA#20 Renesas RL78/G14 16-bit MCU, 32 MHz, 192 KB Flash, 20 KB RAM, 8 KB EEPROM, 48-HWQFN.
