FAQ
What is the maximum operating frequency of the R5F109LBCJFB#10?
The R5F109LBCJFB#10 supports a maximum CPU clock frequency of 24 MHz. This can be achieved using the internal high-speed oscillator (HOCO) or an external crystal/resonator up to 20 MHz with PLL multiplication. The device maintains full functionality across its specified voltage range (1.6–5.5 V) at this speed, with timing margins validated per Renesas Electrical Characteristics table in the RL78/F12 Hardware User's Manual Rev.1.20.
Does the R5F109LBCJFB#10 include on-chip debug capability?
Yes, the R5F109LBCJFB#10 includes a full-featured on-chip debug interface compliant with Renesas' single-wire debug (SWD) protocol. It supports real-time variable watch, instruction trace, and breakpoint management without halting execution. Debug access requires no additional pins beyond the standard SWDIO and SWCLK signals, and is fully supported by Renesas e² studio and CS+ IDEs.
What ADC resolution and channel count does the R5F109LBCJFB#10 provide?
The R5F109LBCJFB#10 integrates a 12-bit successive approximation ADC with 24 selectable input channels. Conversion time is 1.0 µs at maximum speed, and the ADC includes a programmable gain amplifier (PGA), sample-and-hold circuit, and hardware-triggered sequencing - all accessible without CPU intervention via timer or peripheral event triggers.
Is the R5F109LBCJFB#10 qualified for automotive applications?
The R5F109LBCJFB#10 is rated as a Standard-grade Renesas product, intended for industrial, consumer, and office equipment - not certified for automotive AEC-Q100 or transportation-grade use. While it supports LIN physical layer signaling, it lacks automotive-specific qualification, extended temperature screening (-40°C to +105°C), or failure-in-time (FIT) reporting required for automotive ECUs.
What package type and pin count does the R5F109LBCJFB#10 use?
The R5F109LBCJFB#10 uses a 64-pin LQFP package measuring 10 mm × 10 mm with 0.5 mm pitch and an exposed thermal pad (EP). This matches the RL78/F12 64-pin product family pinout defined in Section 1.3.5 of the RL78/F12 Hardware User's Manual, enabling drop-in compatibility within the R5F109Lx series for design reuse and migration.
