Overview
R5F3650MDFA#U0 from Renesas is a 16-bit M16C/65 microcontroller with 512 KB Flash ROM, 32 KB RAM, and integrated 10-bit ADC (26 channels), 8-bit DAC (2 channels), and multiple timer modules including 11-channel 16-bit TimerA/TimerB, PWM, and intelligent I/O for motor control. It operates at up to 50 MHz across 3.0–5.5 V and targets industrial motor drives and embedded control systems.
For engineers reviewing the R5F3650MDFA#U0 datasheet, R5F3650MDFA#U0 pinout, R5F3650MDFA#U0 application, or R5F3650MDFA#U0 equivalent, key selection criteria include its 50 MHz M16C/65 core execution speed, 26-channel 10-bit ADC with sample-and-hold, dual 8-bit DACs, 84 CMOS I/O pins in PLQP0100KB-A package, and support for UART, I²C, and intelligent serial I/O interfaces.
Technical Context
The R5F3650MDFA#U0 implements the M16C/65 CPU core with 108 basic instructions and 20 ns minimum instruction execution time at 50 MHz. It integrates DMACII for peripheral-initiated data transfers and supports four clock sources: main clock, PLL, subclock (125 kHz), and on-chip oscillator.
Its analog subsystem includes a 10-bit ADC with sample-and-hold and 26 input channels, plus two independent 8-bit DACs. Digital peripherals include 11-channel 16-bit TimerA/TimerB, 24-channel intelligent I/O for PWM and encoder input, and dual UART + multi-master I²C interfaces - all synchronized to the same clock domain.

FAQ
What is the maximum operating frequency and supply voltage range for the R5F3650MDFA#U0?
The R5F3650MDFA#U0 operates at a maximum frequency of 50 MHz with a supply voltage range of 3.0 V to 5.5 V. Its M16C/65 core achieves a 20 ns minimum instruction execution time at this speed, and the device includes built-in POR and LVD circuits to ensure stable operation across the full voltage range. The R5F3650MDFA#U0 maintains timing compliance and ADC accuracy across this range when configured per Renesas' recommended decoupling and layout guidelines.
Does the R5F3650MDFA#U0 include on-chip debug support?
Yes, the R5F3650MDFA#U0 supports on-chip debugging via the single-wire background debug interface (BDI), compatible with Renesas E1/E20 emulators. This allows full breakpoint, watchpoint, and memory inspection capabilities without halting real-time peripherals - critical for validating motor control loops and ADC timing. The R5F3650MDFA#U0 debug interface is enabled by default and requires no external debug header pins beyond the standard SWDIO/SWCLK signals.
How many ADC channels does the R5F3650MDFA#U0 support, and what is their resolution and sampling capability?
The R5F3650MDFA#U0 integrates a 10-bit successive-approximation ADC with 26 input channels and sample-and-hold functionality. It supports simultaneous sampling across multiple channels using internal sequencing, with conversion times as low as 1.2 μs per channel. The ADC's input range is configurable (0–VREF or 0–2×VREF), and its performance is specified over the full −40°C to +85°C operating temperature range. This capability is fully implemented in the R5F3650MDFA#U0 silicon and documented in its hardware manual.
Is the R5F3650MDFA#U0 pin-compatible with other members of the M16C/65 family?
The R5F3650MDFA#U0 uses the PLQP0100KB-A package (100-pin LQFP) and shares identical pin mapping with other M16C/65 devices in that package variant, including R5F3650NDFA#U0 and R5F3650KDFA#U0. Pin compatibility covers power, reset, clock, I/O, ADC, DAC, and peripheral interface signals - enabling drop-in replacement where Flash size and RAM requirements align. This pinout consistency is confirmed in the official Renesas M16C/65 Group Hardware Manual.
What serial communication interfaces are integrated into the R5F3650MDFA#U0?
The R5F3650MDFA#U0 integrates two UART channels, one multi-master I²C interface, and specialized serial I/O (SSU) modules supporting clock-synchronous and clock-asynchronous protocols. These interfaces share I/O pins via function multiplexing and support baud rates up to 3 Mbps (UART) and 400 kHz (I²C Fast-mode). All are independently clocked and interrupt-capable, enabling concurrent communication with motor drivers, sensors, and HMIs - a core capability of the R5F3650MDFA#U0 architecture.
