Technical Context

The R5F11BGCGFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.03125 μs at 32 MHz up to 30.5 μs at 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (1–32 MHz), low-speed 15 kHz internal RC, and dual clock domains supporting simultaneous main/subsystem operation.

Its peripheral set includes nine 16-bit timers (TAU, RJ, RD, RG, RX), one 12-bit interval timer, calendar-based RTC with alarm/correction, two comparators with selectable reference, one PGA, and three serial interface groups (CSI, UART/LIN, I²C) - all coordinated via Event Link Controller (22 event sources) and Data Transfer Controller (32 activation sources).

FAQ

What is the maximum operating frequency and corresponding supply voltage range for the R5F11BGCGFB#10?

The R5F11BGCGFB#10 supports up to 32 MHz CPU operation using its high-speed on-chip oscillator (±1.0% accuracy) across VDD = 1.8 V to 5.5 V. At 1.6 V minimum supply, max frequency is reduced to 16 MHz. The device maintains full functionality-including ADC, DAC, and timers-across this entire voltage range, enabling single-supply designs interfacing with diverse logic families.

Does the R5F11BGCGFB#10 support hardware-based background data flash rewriting while executing application code?

Yes, the R5F11BGCGFB#10 implements Background Operation (BGO) for its 4 KB data flash memory. This allows the CPU to execute instructions from program memory concurrently with data flash erase/write operations - essential for over-the-air firmware updates and nonvolatile parameter storage without interrupting real-time tasks.

How many analog input channels does the R5F11BGCGFB#10 support, and what reference options are available for the ADC?

The R5F11BGCGFB#10 features 17 analog input channels (ANI0–ANI7, ANI16–ANI24) with 8/10-bit resolution. The ADC supports VDD as reference, an internal 1.45 V reference, or external AVREFP/AVREFM inputs - enabling high-accuracy measurements across varying supply conditions and sensor types without external reference ICs.

Can the R5F11BGCGFB#10 generate precise audio tones or PWM-driven buzzer signals without external components?

Yes, the R5F11BGCGFB#10 integrates two dedicated programmable clock/buzzer output pins (PCLBUZ0 and PCLBUZ1) capable of generating frequencies from 2.44 kHz to 10 MHz. These outputs support direct drive of piezoelectric buzzers or audio transducers - eliminating external oscillators or driver ICs in HMI and alarm applications.

What industrial temperature certification does the R5F11BGCGFB#10 carry, and how does its voltage detector differ from consumer-grade variants?

The R5F11BGCGFB#10 is qualified for −40°C to +105°C operation (G grade) and includes an 8-stage voltage detector with rising/falling thresholds from 2.61 V to 4.06 V - optimized for industrial brown-out detection under wide-voltage and high-temperature conditions. Consumer-grade A variants offer 14-stage LVD but only to +85°C.
