For engineers reviewing the R5F52104BDFF#V0 datasheet, R5F52104BDFF#V0 pinout, R5F52104BDFF#V0 application, or R5F52104BDFF#V0 equivalent, key selection criteria include its 80-pin LQFP package with 0.65-mm pitch, −40°C to +85°C temperature grade, 5-V-tolerant I/Os, and support for deep software standby with RTC wake-up in low-power embedded systems.
Technical Context
The R5F52104BDFF#V0 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip debugging via FINE interface. It integrates a 50-MHz system clock (ICLK), peripheral clock (PCLK) up to 32 MHz, and dedicated IWDT oscillator at 125 kHz.
Its event-driven operation leverages the Event Link Controller (ELC) to trigger timer, ADC, and communication peripherals without CPU intervention, while the Multi-function Pin Controller (MPC) enables flexible peripheral pin assignment across 52 general-purpose I/Os.

FAQ
What is the maximum operating frequency and performance rating of the R5F52104BDFF#V0?
The R5F52104BDFF#V0 operates at a maximum frequency of 50 MHz and delivers 78 DMIPS of processing performance. This is achieved through its 32-bit RX CPU core with 5-stage pipeline, variable-length instruction set, and zero-wait-state flash access. The R5F52104BDFF#V0 maintains this performance across its full 1.62 V to 5.5 V supply range when voltage conditions meet specification thresholds.
Does the R5F52104BDFF#V0 support IEC60730 Class B compliance features?
Yes, the R5F52104BDFF#V0 integrates dedicated hardware features for IEC60730 Class B compliance, including self-diagnostic functions for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), and RAM testing assistance. These capabilities are documented in the R01DS0041EJ0150 datasheet and reduce external component count for safety-certified appliance designs.
What package type and pin count does the R5F52104BDFF#V0 use?
The R5F52104BDFF#V0 uses the PLQP0080JA-A package: an 80-pin LQFP with 14 × 14 mm body size and 0.65-mm pin pitch. It includes an exposed thermal pad for enhanced heat dissipation. This package variant is specific to chip version B, D-grade (−40°C to +85°C), and is distinct from the 0.5-mm pitch PLQP0080KB-A used in other R5F52104 variants.
How many analog-to-digital and digital-to-analog converter channels does the R5F52104BDFF#V0 provide?
The R5F52104BDFF#V0 includes a 12-bit successive-approximation A/D converter with 8 input channels (AN000–AN002, AN006, AN009–AN012) and two independent 10-bit D/A converters (DA00, DA01). Conversion time is as fast as 1.0 μs per channel at 50 MHz ADCLK, and the A/D module supports synchronized sampling and self-diagnostic modes.
What low-power modes are supported by the R5F52104BDFF#V0, and which peripherals remain active in deep software standby?
The R5F52104BDFF#V0 supports four low-power modes: sleep, all-module clock stop, software standby, and deep software standby. In deep software standby, the RTC remains fully operational using the 32.768 kHz sub-clock, enabling timekeeping and alarm-triggered wake-up while drawing less than 1 μA. The IWDT and selected I/Os retain configuration, but CPU, flash, and most peripherals are powered down.
