Product details
Overview
R5F5634BCDFB#30 from Renesas is a 32-bit RX634 Group microcontroller with 1 Mbyte on-chip flash, 128 Kbytes SRAM, and 32 Kbytes data flash, operating at up to 54 MHz (90 DMIPS) on a 2.7–3.6 V supply. It integrates a 12-bit ADC (16 channels, 1 μs conversion), dual 10-bit DACs, CEC transceiver, dual remote control receivers, ELC, MPC, and supports IEC60730 safety compliance in industrial motor control and home appliance HMI applications.
For engineers reviewing the R5F5634BCDFB#30 datasheet, R5F5634BCDFB#30 pinout, R5F5634BCDFB#30 application, or R5F5634BCDFB#30 equivalent, this page delivers verified technical context, exact package mapping (PLQP0144KA-A, 144-pin LQFP), validated pin functions, real-world use cases, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The R5F5634BCDFB#30 implements the 32-bit RX CPU core with Harvard architecture, 5-stage pipeline, and hardware FPU compliant with IEEE 754 single-precision. It executes floating-point and DSP instructions natively and supports memory protection via an MPU.
Its clock system combines external crystal/oscillator input, internal PLL, dedicated 125-kHz LOCO for IWDT, and Clock Accuracy Check (CAC) circuitry. Peripheral operation is decoupled across four clocks: ICLK (54 MHz max), PCLKB (32 MHz), BCLK (27 MHz), and FCLK (32 MHz), enabling precise power/performance tuning.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F5634ECDFB#30 | Same RX634 core, identical pinout and peripherals, but 2 Mbyte flash (vs. 1 Mbyte) and same 2.7–3.6 V supply | Required where larger firmware image size or future feature expansion is needed; no hardware change required | Select when firmware growth headroom or bootloader+application separation is critical |
| R5F563NEDFB#30 | RX63N Group variant: same 1 Mbyte flash, 128 Kbytes RAM, but lacks CEC, RCR, and external bus; adds USB 2.0 FS host/device | Suitable for USB-connected devices (e.g., smart plugs) but unsuitable for CEC/IR-based appliances or external memory expansion | Choose only if USB connectivity outweighs CEC/RCR needs and external bus is unused |
