Technical Context

The R5F52107CDFN#30 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 multiply-accumulate operations. It integrates an ELC that routes 59 event signals directly to peripherals without CPU intervention, enabling synchronized low-latency operation during sleep modes.

Its clock system includes independent PLL, sub-clock (32.768 kHz), high-/low-speed on-chip oscillators, and CAC circuit for clock accuracy validation. Power management supports four low-power modes including deep software standby with RTC active, and voltage detection across three circuits with programmable thresholds.

Which package type and pin count does the R5F52107CDFN#30 use?

The R5F52107CDFN#30 uses an 80-pin LQFP package (PLQP0080KB-A) measuring 12 × 12 mm with 0.5-mm pitch. This RoHS-compliant, lead-free package supports 64 general-purpose I/O pins, 4 of which are 5-V tolerant, and provides full access to its integrated peripherals including SCI, I²C, RSPI, A/D, D/A, and RTC - matching the mechanical and thermal requirements of compact industrial control boards.

Does the R5F52107CDFN#30 support functional safety standards like IEC60730?

Yes, the R5F52107CDFN#30 includes hardware-assisted functions for IEC60730 Class B compliance, including self-diagnostic A/D converter, clock accuracy measurement circuit (CAC), independent watchdog timer (IWDT), and RAM test assistance logic. These features are documented in the R5F52107CDFN#30 datasheet and enable certified implementations in household appliances and industrial controllers without requiring external safety monitors.

What analog peripherals are integrated into the R5F52107CDFN#30?

The R5F52107CDFN#30 integrates a 12-bit A/D converter with 14 input channels (AN000–AN013), 1 μs conversion time, and sample-and-hold on three channels; two 10-bit D/A converters (DA0, DA1); two 2-channel analog comparators (CMPA, CMPB); and an on-die temperature sensor with selectable PGA gain.
