Renesas R5F3650MCDFB#30

Overview

R5F3650MCDFB#30 from Renesas is a 16-bit M16C/60 Series CPU core microcontroller with 512 KB program ROM, 31 KB data flash, and 16 KB RAM, operating at up to 32 MHz (2.7–5.5 V). It integrates dual A/D converters (10-bit × 26 channels), two 8-bit D/A outputs, CEC interface, real-time clock, and three-phase motor control timers - deployed in industrial HMI and consumer audio/video systems.

For engineers reviewing the R5F3650MCDFB#30 datasheet, R5F3650MCDFB#30 pinout, R5F3650MCDFB#30 application, or R5F3650MCDFB#30 equivalent, key selection criteria include its 100-pin LQFP package (PLQP0100KB-A), -40°C to +85°C industrial temperature grade, on-chip debug support, and CEC compliance for HDMI-adjacent control subsystems.

Technical Context

The R5F3650MCDFB#30 implements the M16C/60 CPU core with 16×16-bit multiplier and MAC instruction, enabling deterministic motor control loops. Its peripheral set includes six 16-bit Timer B units for pulse width/period measurement and three-phase inverter timing with integrated dead-time generation.

Clock architecture comprises five independent sources: main crystal (up to 20 MHz), sub-clock (32.768 kHz), low-speed on-chip oscillator (125 kHz), high-speed on-chip oscillator (40 MHz ±5%), and PLL frequency synthesizer - supporting flexible system timing and low-power wait/stop modes.

FAQ

What is the maximum operating frequency and supply voltage range for the R5F3650MCDFB#30?

The R5F3650MCDFB#30 operates at up to 32 MHz with a supply voltage range of 2.7 V to 5.5 V on both VCC1 and VCC2. At 32 MHz, the minimum instruction execution time is 31.25 ns under full voltage conditions. The device maintains full functionality across the entire voltage range without frequency derating.

Does the R5F3650MCDFB#30 support CEC functionality, and how is it implemented?

Yes, the R5F3650MCDFB#30 includes a fully compliant HDMI CEC transceiver. It is implemented on pin P8_5 (NMI/SD/CEC) and operates at 32 kHz. The hardware handles CEC arbitration loss detection, automatic ACK output, and message framing - eliminating need for external protocol logic.

How many A/D and D/A converter channels does the R5F3650MCDFB#30 provide, and what are their resolutions?

The R5F3650MCDFB#30 provides a 10-bit A/D converter with 26 input channels (including AN0_0–AN0_7, AN2_0–AN2_7, ANEX0/ANEX1, AN0–AN7) and two independent 8-bit D/A converter channels (DA0 and DA1 on P9_3 and P9_4). Conversion time is 1.72 µs per sample.

What package type and pin count does the R5F3650MCDFB#30 use, and is it RoHS-compliant?

The R5F3650MCDFB#30 uses a 100-pin LQFP package (PLQP0100KB-A), 14 mm × 14 mm body size, 0.5 mm lead pitch. Per Renesas documentation, this package is RoHS-compliant and halogen-free, meeting JEDEC standards for industrial reflow profiles.

Can the R5F3650MCDFB#30 perform three-phase motor control, and which peripherals enable it?

Yes, the R5F3650MCDFB#30 supports three-phase inverter control using dedicated hardware: Timer A1, A2, A4 and Timer B2 generate complementary PWM outputs, and the on-chip dead-time timer inserts precise delays between high-side and low-side gate signals - all managed without CPU intervention.
