FAQ
What is the maximum operating frequency and supply voltage range for R5F2136ACNFA#30?
The R5F2136ACNFA#30 operates at up to 20 MHz when supplied with 2.7–5.5 V, and supports reduced-frequency operation down to 5 MHz at 1.8 V. This dual-voltage capability allows deployment in both standard 3.3 V/5 V systems and battery-powered designs where low-voltage tolerance is critical. The minimum instruction execution time is 50 ns under full-speed conditions.
Does R5F2136ACNFA#30 support background programming of its data flash memory?
Yes, the R5F2136ACNFA#30 supports Background Operation (BGO) for its 8 KB data flash (four 1 KB blocks). This allows the CPU to execute application code while simultaneously erasing or programming flash sectors - essential for over-the-air updates, runtime parameter storage, and calibration data persistence without system interruption.
How many PWM output channels does R5F2136ACNFA#30 provide, and what advanced modes are supported?
The R5F2136ACNFA#30 provides up to six PWM output channels via Timer RD, supporting complementary PWM with programmable dead time, three-phase synchronous reset, sawtooth/triangular wave modulation, and fixed-period PWM3 mode. These capabilities enable direct control of 3-phase inverters for BLDC and PMSM motors without external gate driver logic.
Is hardware LIN bus support integrated into R5F2136ACNFA#30, and how is it implemented?
Yes, R5F2136ACNFA#30 includes dedicated hardware LIN support implemented through coordinated operation of Timer RA and UART0. This offloads LIN protocol timing, checksum calculation, and frame synchronization from firmware, ensuring strict compliance with LIN 2.x specifications and freeing CPU resources for application tasks.
What analog peripherals are integrated into R5F2136ACNFA#30, and how are they configured?
R5F2136ACNFA#30 integrates a 12-channel 10-bit ADC with sample-and-hold and sweep mode, two independent 8-bit DACs (DA0/DA1), and two comparator B circuits with configurable reference inputs. ADC channels share pins with GPIO and timers; DAC outputs map to P0_6 (DA0) and P0_7 (DA1), enabling simultaneous analog sensing and actuation in closed-loop systems.
