FAQ
What is the operating temperature range for the R5F21357CYFP#V0?
The R5F21357CYFP#V0 is a D-version device rated for an operating ambient temperature range of –40°C to +85°C. This specification is confirmed in the R8C/35A Group datasheet (REJ03B0225-0100 Rev.1.00, p.3), and applies to the R5F21357CYFP#V0 as a member of the D-version product line. The device meets this rating under specified VCC conditions (1.8–5.5 V) and load conditions.
Does the R5F21357CYFP#V0 support in-system programming via standard interfaces?
Yes, the R5F21357CYFP#V0 supports in-system programming using the on-chip debug interface and background operation (BGO) function. Firmware updates can be performed via UART or dedicated debug pins without removing the device from the PCB. The R5F21357CYFP#V0's data flash allows erasure and reprogramming of individual 1-KB blocks while the CPU executes application code from program ROM.
What peripheral resources does the R5F21357CYFP#V0 allocate for LIN bus communication?
The R5F21357CYFP#V0 implements hardware LIN 2.1/SAE J2602 using UART0 for serial framing and Timer RA for baud rate generation and synchronization. This dedicated LIN module eliminates software bit-banging overhead and ensures timing accuracy compliant with LIN specification tolerances. No external transceiver is required for basic node operation, though one is needed for bus termination and level translation in multi-node systems.
How many analog input channels does the R5F21357CYFP#V0 support, and what is their resolution?
The R5F21357CYFP#V0 integrates a 10-bit successive-approximation ADC with 12 analog input channels (AN0–AN11). Each channel supports sample-and-hold operation and can be scanned in sweep mode. The ADC accepts input voltages from 0 V to AVCC and includes internal reference options, enabling precise measurement of temperature sensors, potentiometers, and current-sense amplifiers without external components.
Is the R5F21357CYFP#V0 pin-compatible with other members of the R8C/35A Group?
Yes, all R8C/35A Group devices-including R5F21354 through R5F2135C variants in FP (LQFP-52) package-are pin-compatible. The R5F21357CYFP#V0 shares identical pin assignment, electrical characteristics, and peripheral mapping with other 52-pin members such as R5F21356ADFP and R5F21358ADFP. Firmware portability is supported within the group, subject to memory size and feature enablement (e.g., D-version functions require D-marked silicon).
