FAQ

What is the maximum operating frequency of the R5F2136ACDFP#V0 and under what conditions?

The R5F2136ACDFP#V0 achieves a maximum operating frequency of 20 MHz when powered at 2.7–5.5 V using the XIN clock source. At reduced supply voltages (1.8–5.5 V), the maximum frequency drops to 5 MHz to ensure timing margin and stability - verified in Table 1.2 of the R01DS0018EJ0110 datasheet.

Does the R5F2136ACDFP#V0 support in-system programming of its program flash memory?

Yes, the R5F2136ACDFP#V0 supports in-system programming via its on-chip debug interface. The device includes ROM code protection and ID code check features, and the flash memory is rated for 1,000 write/erase cycles - enabling secure field firmware updates without removing the R5F2136ACDFP#V0 from the PCB.

How many analog input channels does the R5F2136ACDFP#V0 ADC support, and what is its resolution?

The R5F2136ACDFP#V0 integrates a 10-bit successive-approximation ADC with 12 analog input channels (AN0–AN11). It includes sample-and-hold functionality and sweep mode for automatic sequential conversion - allowing continuous monitoring of multiple sensors without CPU intervention.

What peripheral modules are used to implement the hardware LIN interface on the R5F2136ACDFP#V0?

The hardware LIN interface on the R5F2136ACDFP#V0 is implemented using UART0 combined with Timer RA. This pairing provides full LIN 2.0/2.1 protocol support including break detection, sync field generation, and checksum calculation - eliminating software overhead and ensuring deterministic timing for automotive body electronics and appliance networks.

Is the R5F2136ACDFP#V0 pin-compatible with other members of the R8C/36C Group, such as the R5F21366CDFP?

Yes, the R5F2136ACDFP#V0 shares the same 64-pin LQFP package (PLQP0064KB-A) and identical pinout with all R8C/36C Group variants including R5F21366CDFP. Peripheral pin assignments, power/ground locations, and reset configuration are functionally identical - enabling drop-in replacement within the same package family when memory requirements align.
