For engineers reviewing the R5F52107CDFF#V0 datasheet, R5F52107CDFF#V0 pinout, R5F52107CDFF#V0 application, or R5F52107CDFF#V0 equivalent, this MCU supports deterministic real-time control with low-power deep software standby mode, event-driven peripheral operation via ELC, and flexible I/O mapping via MPC - critical for embedded systems requiring functional safety and power efficiency.

Technical Context

The R5F52107CDFF#V0 implements a CISC Harvard-architecture 32-bit RX CPU core with 5-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32-bit multiplication. It integrates dual clock domains: ICLK (50 MHz max) for CPU/system and PCLK (32 MHz max) for peripherals.

Its timing subsystem includes sub-clock RTC (32.768 kHz), PLL (4–12.5 MHz input), IWDT-dedicated oscillator (125 kHz), and CAC for clock accuracy validation. The device supports four low-power modes, including deep software standby with RTC active and event-triggered wake-up via ELC.

FAQ

What is the maximum operating frequency and core performance of the R5F52107CDFF#V0?

The R5F52107CDFF#V0 operates at a maximum frequency of 50 MHz and delivers 78 DMIPS of processing performance using its 32-bit RX CPU core. Its 5-stage pipeline, variable-length instruction set, and hardware 32×32-bit multiplier/divider enable deterministic real-time execution. The R5F52107CDFF#V0 achieves zero-wait-state access to both 384 KB flash and 64 KB SRAM at full speed, ensuring consistent throughput for control loops and communication stacks.

Does the R5F52107CDFF#V0 support functional safety standards like IEC60730?

Yes, the R5F52107CDFF#V0 includes built-in hardware features for IEC60730 Class B compliance, including self-diagnostic support for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), and RAM test assistance functions. These capabilities reduce external component count and simplify certification for household appliances and industrial equipment. The R5F52107CDFF#V0 is rated for −40°C to +85°C operation, aligning with standard industrial environmental requirements.

What package type and pin count does the R5F52107CDFF#V0 use?

The R5F52107CDFF#V0 uses the PLQP0080JA-A package: an 80-pin LQFP with 14 × 14 mm body size and 0.65-mm pin pitch. This RoHS-compliant, lead-free package supports surface-mount assembly and provides 64 general-purpose I/O pins with MPC remapping, 4 pins tolerant to 5 V, and dedicated pins for main/sub clocks, reset, and debug interface. The R5F52107CDFF#V0 is not pin-compatible with 100-pin or 144-pin RX210 variants.

How does the Event Link Controller (ELC) enhance real-time performance in the R5F52107CDFF#V0?

The ELC in the R5F52107CDFF#V0 enables direct hardware-level connection of 59 event sources (e.g., timer overflows, ADC completions, GPIO transitions) to peripheral modules without CPU or interrupt involvement. This eliminates software latency and jitter - for example, an MTU2 timer overflow can trigger an ADC conversion or RSPI transfer within one clock cycle. The R5F52107CDFF#V0 leverages ELC to maintain deterministic response in motor control, sensor fusion, and protocol timing-critical applications.

What are the key differences between R5F52107CDFF#V0 and R5F52107ADFP#V0?

The R5F52107CDFF#V0 (Chip Version C) and R5F52107ADFP#V0 (Chip Version A) share identical flash (384 KB), RAM (64 KB), and package (80-pin LQFP), but differ in peripheral inclusion: the R5F52107CDFF#V0 includes RTC and TPU timer units, while R5F52107ADFP#V0 omits both. This makes the R5F52107CDFF#V0 suitable for time-stamped data logging and encoder-based motion control - functions unsupported by R5F52107ADFP#V0. Both operate from −40°C to +85°C.
