FAQ
What is the maximum operating frequency of the R5F64167PFB#UB?
The R5F64167PFB#UB is a normal-speed version rated for 50 MHz operation at VCC = 3.0 to 5.5 V. Its CPU core supports up to 64 MHz in high-speed variants (e.g., R5F64167HPFD#UA), but the R5F64167PFB#UB itself is specified for 50 MHz maximum - ensuring thermal stability and timing margin in industrial ambient conditions.
Does the R5F64167PFB#UB include an integrated floating-point unit?
Yes, the R5F64167PFB#UB integrates an IEEE-754 compatible single-precision floating-point unit (FPU) as part of its R32C/100 Series CPU core. This enables efficient execution of trigonometric, exponential, and filtering operations essential for motor control algorithms and audio DSP without software emulation overhead.
How many analog-to-digital converter channels does the R5F64167PFB#UB support?
The R5F64167PFB#UB supports 34 channels of 10-bit analog-to-digital conversion with integrated sample-and-hold. This includes dedicated AN_0–AN_7 (P10_0–P10_7), AN0_0–AN0_7 (P0_0–P0_7), and AN15_0–AN15_7 (P15_0–P15_7), plus additional analog inputs mapped to timer and serial function pins.
What is the purpose of the OUTC2_x pins on the R5F64167PFB#UB?
The OUTC2_x pins (e.g., OUTC2_0 on P7_0, OUTC2_2 on P7_1) are outputs of the 8-bit programmable dead-time timer used exclusively by the three-phase motor control timer block. They drive external gate drivers with configurable delay to prevent shoot-through in inverter half-bridges - a hardware safety feature critical for BLDC and PMSM drives.
Is on-chip debug supported for the R5F64167PFB#UB?
Yes, the R5F64167PFB#UB includes full on-chip debug (OCD) capability via the standard Renesas E1/E20 emulator interface. This enables real-time breakpoint setting, register inspection, and flash programming during development - eliminating need for external debug probes beyond standard JTAG/SWD adapters.
