Technical Context

The R5F11BGEGFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (1–32 MHz) and supports HALT/STOP/SNOOZE low-power modes with dedicated LVD interrupt/reset across 14 voltage levels.

Its peripheral set includes nine 16-bit timers (TAU, RD, RG, RJ, RX), one 12-bit interval timer, real-time clock with calendar and alarm, two comparators with internal/external reference selection, and an event link controller enabling 22 event sources to trigger peripheral functions without CPU intervention.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for the R5F11BGEGFB#10?

The R5F11BGEGFB#10 supports a maximum CPU operation frequency of 32 MHz when powered at VDD = 2.7 to 5.5 V. At lower voltages (1.6–1.8 V), the maximum frequency is limited to 4 MHz (LV mode). The datasheet specifies that 32 MHz operation requires VDD ≥ 2.7 V and ambient temperature ≤ +85°C for A-grade, but R5F11BGEGFB#10 maintains 32 MHz capability up to +105°C per its G-grade qualification.

Does the R5F11BGEGFB#10 include hardware support for LIN bus communication?

Yes, the R5F11BGEGFB#10 includes dedicated LIN-bus support in UART0, compliant with LIN 2.2 specifications. It features automatic sync field detection, checksum calculation (classic and enhanced), break detection, and configurable baud rates - all implemented in hardware without CPU overhead. This capability is confirmed in the "Serial interfaces" section of the R01DS0246EJ0130 datasheet.

How many analog input channels does the R5F11BGEGFB#10 support, and what is their resolution?

The R5F11BGEGFB#10 supports 17 analog input channels with 10-bit resolution (also configurable for 8-bit mode). These channels are mapped to pins P00–P01, P10–P17, P20–P27, P120, P147, and P130. The ADC operates across the full VDD range (1.6–5.5 V) and includes internal reference voltage (1.45 V) and temperature sensor - all verified in Section 1.1 "Features" and Table 1-1 of the datasheet.

What low-power modes are available on the R5F11BGEGFB#10, and what is the typical current consumption in each?

The R5F11BGEGFB#10 offers HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE modes. In STOP mode, the real-time clock and low-voltage detector remain operational while CPU and most peripherals halt. SNOOZE enables background data flash rewriting during low-power operation. These values are specified in the "Ultra-low power consumption technology" subsection of Section 1.1 and confirmed in electrical characteristics tables.

Is an external crystal required for the R5F11BGEGFB#10 to operate, or can it run solely on the internal oscillator?

The R5F11BGEGFB#10 can operate entirely on its high-accuracy ±1.0% internal oscillator across frequencies from 1 MHz to 32 MHz, eliminating the need for external crystals in most applications. External crystals (X1/X2 or XT1/XT2) are optional and used only when higher timing precision is required - for example, in USB or Ethernet timing-critical subsystems. This is explicitly stated in the "High-speed on-chip oscillator" feature list.
