Renesas R5F52206BDFP#30

Overview

R5F52206BDFP#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (49 DMIPS), featuring 256 KB on-chip flash, 16 KB SRAM, 8 KB data flash, 12-bit A/D converter (16 channels, 1.56 μs conversion), and integrated RTC with IEC60730 support - deployed in industrial control panels requiring deterministic real-time response and functional safety compliance.

For engineers reviewing the R5F52206BDFP#30 datasheet, R5F52206BDFP#30 pinout, R5F52206BDFP#30 application, or R5F52206BDFP#30 equivalent, key selection criteria include its 100-pin LQFP package, 32 MHz max frequency under 2.7–5.5 V supply, ELC-triggered peripheral operation, MPC-configurable I/O mapping, and IrDA-capable SCI5 channel for embedded HMI communication interfaces.

Technical Context

The R5F52206BDFP#30 implements a CISC Harvard architecture with 5-stage pipeline, 64-bit accumulator for single-cycle 32×32 multiply-accumulate, and on-chip multiplication/division unit executing 32×32 operations in one CPU cycle. It supports little-endian instruction/data layout with selectable big-endian data mode.

Its clock system integrates main (up to 20 MHz crystal), sub-clock (32.768 kHz), high-speed/low-speed on-chip oscillators, and IWDT-dedicated 125-kHz oscillator - all managed via independent ICLK/PCLK/FCLK domains. The ELC enables direct event-driven peripheral activation without CPU intervention, including MTU2 timer triggers for A/D conversion start.

FAQ

What is the maximum operating frequency of the R5F52206BDFP#30 and under what voltage conditions?

The R5F52206BDFP#30 operates at a maximum frequency of 32 MHz when supplied with 2.7–5.5 V. At reduced supply voltages (1.62–2.7 V), the maximum frequency is derated to 8 MHz. This dual-voltage operation enables flexible power design in battery-backed or wide-input industrial power supplies. The R5F52206BDFP#30 maintains full peripheral functionality across both ranges, including flash access without wait states.

Does the R5F52206BDFP#30 support IrDA communication, and how is it implemented?

Yes, the R5F52206BDFP#30 supports IrDA 1.0-compliant infrared communication via SCI5, using dedicated pins IRTXD5 (transmit) and IRRXD5 (receive). The implementation leverages the SCI's clock-synchronous mode with built-in encoding/decoding logic - no external transceiver required. This capability is confirmed in the datasheet's SCIe feature list and pin function table, and is validated for use in handheld diagnostic tools interfacing with the R5F52206BDFP#30.

How many A/D converter channels does the R5F52206BDFP#30 have, and what is its minimum conversion time?

The R5F52206BDFP#30 integrates a 12-bit A/D converter with 16 input channels (AN000–AN015). Its minimum conversion time is 1.56 μs per channel when the A/D clock (ADCLK) runs at 32 MHz. This performance is specified in the "12-bit A/D converter" section of the datasheet and applies to all 16 channels in single-scan or group-scan modes. The R5F52206BDFP#30 also supports sample-and-hold and self-diagnostic functions for enhanced measurement reliability.

What low-power modes are available on the R5F52206BDFP#30, and how do they affect peripheral operation?

The R5F52206BDFP#30 offers three low-power modes: Sleep mode (CPU stopped, peripherals active), All-module Clock Stop mode (all clocks halted except sub-clock), and Software Standby mode (minimal current draw with RTC and IWDT operational). In Sleep mode, peripherals like MTU2, SCI, and A/D remain fully functional and can be triggered by ELC events - enabling wake-up on timer expiry or serial data arrival without CPU involvement. The R5F52206BDFP#30 retains full register state and SRAM content across all modes.

Is the R5F52206BDFP#30 pin-compatible with other members of the RX220 Group, and which packages share the same footprint?

Yes, the R5F52206BDFP#30 uses the PLQP0100KB-A 100-pin LQFP package (14 × 14 mm, 0.5-mm pitch), which is mechanically and electrically identical to other RX220 Group parts with the "FP" suffix (e.g., R5F52205BDFP#30, R5F52203BDFP#30). All FP-package variants share identical pin count, pitch, and signal mapping - enabling drop-in replacement for memory- or feature-downgraded versions without PCB redesign. The R5F52206BDFP#30 pinout is fully documented in Figure 1.3 and Table 1.5 of the datasheet.
