Product details
Overview
R5F52108CDFN#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 50 MHz (78 DMIPS), featuring 512 KB on-chip flash, 64 KB SRAM, 8 KB data flash, 12-bit A/D converter (12 channels), and dual 10-bit D/A converters. It serves as a main control unit in industrial HMI, smart sensor nodes, and power management systems requiring IEC60730 compliance.
For engineers reviewing the R5F52108CDFN#30 datasheet, R5F52108CDFN#30 pinout, R5F52108CDFN#30 application, or R5F52108CDFN#30 equivalent, this page delivers verified specifications, package mapping to PLQP0080KB-A (12 × 12 mm, 0.5-mm pitch), functional coverage of ELC, MPC, RTC, and confirmed alternatives for migration or second-sourcing.
Technical Context
The R5F52108CDFN#30 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and deterministic interrupt latency. Its clock system integrates PLL, sub-clock oscillator (32.768 kHz), and dedicated IWDT oscillator (125 kHz), with independent domain clocks (ICLK up to 50 MHz, PCLK up to 32 MHz).
It supports four low-power modes including deep software standby with RTC active, and features event-driven operation via ELC-allowing peripheral modules (e.g., MTU2, TPU) to trigger without CPU intervention. The chip version C variant includes full RTC support and 12-channel A/D conversion, distinguishing it from version A/B variants with reduced channel counts in smaller packages.

FAQ
What is the maximum operating frequency and voltage range for the R5F52108CDFN#30?
The R5F52108CDFN#30 operates at up to 50 MHz when supplied with 2.7–5.5 V, 32 MHz at 1.8–2.7 V, and 20 MHz at 1.62–1.8 V. Its single-supply design eliminates need for separate core/I/O rails, simplifying power architecture. All performance metrics-including 78 DMIPS and zero-wait-state flash access-are validated within these ranges per R01DS0041EJ0150 Rev.1.50.
Does the R5F52108CDFN#30 include a real-time clock (RTC), and what features does it support?
Yes, the R5F52108CDFN#30 includes a fully featured RTC module compliant with chip version C specifications. It supports calendar mode (year/month/day/hour/minute/second), binary second counter mode, leap year and 30-second adjustments, time capture on external event pins, and RTC-initiated wake-up from deep software standby mode-enabling precise timestamping and low-power scheduling.
How many A/D and D/A channels does the R5F52108CDFN#30 provide, and what are their key electrical specs?
The R5F52108CDFN#30 integrates a 12-bit S12AD converter with 12 input channels (AN000–AN011), 1 μs minimum conversion time at 50 MHz ADCLK, and sample-and-hold on three channels. It also provides two independent 10-bit D/A channels (DA0, DA1) with output range 0 V to VREFH-supporting simultaneous analog output generation for calibration or actuator control.
What low-power modes are supported by the R5F52108CDFN#30, and what is the lowest achievable current draw?
The R5F52108CDFN#30 supports four low-power modes: sleep, all-module clock stop, software standby, and deep software standby. In deep software standby with RTC active and no peripherals running, typical current draw is below 1 μA. The RTC remains fully operational and can generate wake-up interrupts-making it ideal for battery-backed timekeeping and periodic sensor polling.
Is the R5F52108CDFN#30 pin-compatible with other RX210 Group MCUs in the same package?
No-pin compatibility is not guaranteed across RX210 variants even in identical packages (e.g., PLQP0080KB-A). While R5F52108CDFN#30 shares the 80-pin LQFP footprint with R5F52108BDFN#30 and R5F52108ADFN#V0, differences in peripheral enablement (e.g., RTC presence, A/D channel count, MPC configuration) and signal multiplexing require review of individual pin function tables. Board reuse requires validation against each variant's datasheet.
