Technical Context
The R5F11EBAAFP#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and hardware multiply/divide/accumulate instructions. It integrates a 12-bit interval timer, watchdog timer, event link controller (19 event inputs), and programmable clock/buzzer output unit supporting frequencies from 2.44 kHz to 10 MHz.
Its analog subsystem includes an 8/10-bit ADC with internal 1.45 V reference and temperature sensor (HS mode only), two comparators with 8-bit DAC reference selection, and a single PGA channel.

FAQ
What is the maximum operating frequency of the R5F11EBAAFP#50?
The R5F11EBAAFP#50 supports a maximum system clock frequency of 24 MHz using its high-speed on-chip oscillator (±2% accuracy) or 20 MHz when driven by an external crystal oscillator. Instruction execution time ranges from 0.04167 µs (24 MHz) to 1.0 µs (1 MHz), configurable per application requirements.
Does the R5F11EBAAFP#50 support in-system programming?
Yes, the R5F11EBAAFP#50 supports self-programming of its 16 KB flash memory via the on-chip debug interface or user firmware using the flash shield window function. This enables field firmware updates without external programmers, though Renesas cautions against using the on-chip debug function in mass-produced units due to flash endurance limits.
How many analog input channels does the R5F11EBAAFP#50 have?
The R5F11EBAAFP#50 provides 12 analog input channels: ANI0–ANI3 on Port 2, plus ANI16–ANI19 mapped to P01, P00, P147, and P120 respectively. All channels support 8/10-bit resolution A/D conversion with VDD = 2.7–5.5 V, and internal 1.45 V reference voltage is available for precision measurements.
What low-power modes are available on the R5F11EBAAFP#50?
The R5F11EBAAFP#50 offers HALT, STOP, and SNOOZE low-power modes. STOP mode achieves ≤0.23 µA (typ.) current consumption at 3.0 V, while SNOOZE allows selected peripherals (e.g., ADC, timers) to operate autonomously during low-power sleep - ideal for periodic sensor sampling without full CPU wake-up.
Is the R5F11EBAAFP#50 pin-compatible with other RL78/G1G variants?
Yes, the R5F11EBAAFP#50 shares identical 32-pin LQFP (7×7 mm) packaging and pinout with R5F11EB8AFP#50, enabling drop-in replacement where flash capacity permits. However, it is not pin-compatible with 30-pin LSSOP or 44-pin LQFP variants like R5F11EFAAFP#50 due to differing pin counts and signal allocations.
