Product details
Overview
R5F52107CDFP#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 50 MHz (78 DMIPS), featuring 384 KB on-chip flash, 64 KB SRAM, 8 KB data flash, 12-bit A/D converter (16 channels), 10-bit D/A converter (2 channels), RTC, ELC, MPC, and IEC60730-compliant safety functions - deployed in industrial control panels requiring deterministic real-time response and low-power operation.
For engineers reviewing the R5F52107CDFP#30 datasheet, R5F52107CDFP#30 pinout, R5F52107CDFP#30 application, or R5F52107CDFP#30 equivalent, key selection criteria include its 100-pin LQFP package (PLQP0100KB-A), 50-MHz max frequency with 1.62–5.5 V supply range, integrated RTC with deep software standby wake-up, and dual 10-bit DACs for analog output generation in closed-loop systems.
Technical Context
The R5F52107CDFP#30 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It supports little-endian or big-endian data arrangement and includes a dedicated 64-bit accumulator for single-cycle 32×32-bit multiply-accumulate operations.
Its clock system integrates multiple oscillators - main (up to 20 MHz), sub-clock (32.768 kHz), high-speed/low-speed on-chip oscillators, and PLL - with independent domain clocks (ICLK/PCLK/BCLK/FCLK) enabling precise power/performance trade-offs across CPU, peripherals, external bus, and FlashIF subsystems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52107ADFP#V0 | Chip version A; lacks RTC and TPU; only 4 SCI channels vs. 12; no ELC or MPC | Suitable for cost-sensitive, non-time-critical embedded control without calendar functions or advanced peripheral linking | Select when RTC, ELC, or MPC are unnecessary and BOM cost reduction is prioritized over future feature scalability |
| R5F52107BDFP#30 | Chip version B; adds external bus interface (16-bit), TPU unit, and 144-pin LQFP option; same flash/SRAM | Required for designs needing external memory expansion or higher I/O count; supports larger firmware images via external NOR flash | Choose when external memory mapping or additional timer resources (TPU) are needed beyond R5F52107CDFP#30's integrated capabilities |
Compared with R5F52107ADFP#V0, R5F52107CDFP#30 delivers full RTC, ELC, and MPC functionality essential for time-aware and reconfigurable systems; versus R5F52107BDFP#30, it omits the external bus but retains identical core performance and analog peripherals in a smaller 100-pin footprint.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F52107CDFP#30?
The R5F52107CDFP#30 operates at a maximum frequency of 50 MHz, delivering 78 DMIPS of processing performance. This is achieved using the 32-bit RXv1 CPU core with a 5-stage pipeline and ultra-compact instruction encoding. Its performance enables real-time execution of complex control algorithms, such as field-oriented motor control or multi-channel sensor fusion, without instruction wait states due to its zero-wait-state flash and SRAM architecture.
Does the R5F52107CDFP#30 support real-time clock functionality with battery backup capability?
Yes, the R5F52107CDFP#30 integrates a full-featured RTC module driven by a dedicated 32.768 kHz sub-clock oscillator. It supports calendar/timekeeping, alarm interrupts, periodic interrupts, carry interrupts, and time-capture functions. Crucially, the RTC remains operational during deep software standby mode - enabling timekeeping with minimal current draw - and can initiate wake-up from that mode upon alarm or periodic event, making it suitable for battery-backed timestamping in energy meters or security systems.
How many analog-to-digital and digital-to-analog converter channels does the R5F52107CDFP#30 provide?
The R5F52107CDFP#30 includes one 12-bit successive-approximation A/D converter (S12AD) with 16 input channels and two independent 10-bit D/A converters (DA). The A/D converter achieves a minimum conversion time of 1.0 µs per channel when ADCLK runs at 50 MHz and supports synchronized sampling across three channels. The dual 10-bit DACs output voltage from 0 V to VREFH and are commonly used for analog setpoint generation, sensor biasing, or waveform synthesis in closed-loop control systems.
What low-power modes are available on the R5F52107CDFP#30, and which peripherals remain active in deep software standby?
The R5F52107CDFP#30 offers four low-power consumption modes: sleep mode, all-module clock stop mode, software standby mode, and deep software standby mode. In deep software standby, the CPU and most peripherals are halted, but the RTC, IWDT, and sub-clock oscillator remain active. This mode achieves sub-1 µA typical current consumption while preserving calendar/timekeeping and enabling wake-up via RTC alarm, external pin event, or IWDT timeout - ideal for battery-powered monitoring nodes.
Is the R5F52107CDFP#30 pin-compatible with other members of the RX210 Group, such as R5F52107ADFP#V0 or R5F52107BDFP#30?
No, the R5F52107CDFP#30 is not pin-compatible with R5F52107ADFP#V0 or R5F52107BDFP#30. While all three share the same 100-pin LQFP (PLQP0100KB-A) package and mechanical footprint, their functional pin assignments differ significantly due to chip version differences: R5F52107ADFP#V0 (version A) lacks RTC, ELC, and MPC signals; R5F52107BDFP#30 (version B) includes external bus pins (e.g., CS0#, RD#, WR#) absent in version C. PCB layout must be verified against the specific version's pin configuration table.
