Product details
Overview
R5F3650MNFB#U0 from Renesas is a 16-bit M16C/60 Series core microcontroller with 512 KB program flash, 31 KB data flash, and 16 KB RAM, operating at up to 32 MHz with 2.7–5.5 V supply. It integrates dual A/D converters (10-bit × 26 channels), two 8-bit D/A outputs, six UARTs, multi-master I²C, CEC interface, real-time clock, and three-phase motor control timers - deployed in industrial HMI and consumer audio/video systems.
For engineers reviewing the R5F3650MNFB#U0 datasheet, R5F3650MNFB#U0 pinout, R5F3650MNFB#U0 application, or R5F3650MNFB#U0 equivalent, key selection criteria include its 100-pin LQFP (PLQP0100KB-A) package, -20°C to +85°C temperature grade, on-chip debug support, and CEC compliance for HDMI-adjacent control subsystems.
Technical Context
The R5F3650MNFB#U0 implements the M16C/60 CPU core with 16×16-bit multiplier and MAC instruction, enabling deterministic motor control loop execution. Its peripheral set includes Timer A (5×16-bit) and Timer B (6×16-bit) with dedicated three-phase inverter logic, on-chip dead-time generation, and encoder input processing.
System-level timing is managed by five independent clock 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 ±10%), and PLL frequency synthesizer - all supporting wait/stop power-saving modes and oscillation stop detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F3650MNFA#U0 | Same core, memory, and peripherals; packaged in 100-pin QFP (PRQP0100JD-B) instead of LQFP; identical -20°C to +85°C rating. | Preferred where legacy PCB layout uses QFP footprint or requires different thermal pad characteristics. | Select R5F3650MNFA#U0 only when mechanical compatibility with PRQP0100JD-B is required; electrical behavior is identical. |
| R5F3651MNFC#U0 | 512 KB program ROM + 31 KB data flash + 16 KB RAM, but in 128-pin LQFP (PLQP0128KB-A); adds 26 additional GPIO and expanded external bus interface. | Suitable for designs needing >85 GPIO, wider data bus (16-bit), or memory expansion beyond 1 MB address space. | Choose R5F3651MNFC#U0 when pin count, external memory bandwidth, or I/O density exceeds R5F3650MNFB#U0 capabilities. |
Compared with R5F3650MNFA#U0, the R5F3650MNFB#U0 offers identical functionality in a finer-pitch LQFP package with better thermal performance; versus R5F3651MNFC#U0, it trades pin count and bus width for compactness and lower BOM cost in space-constrained consumer applications.

FAQ
What is the maximum operating frequency and voltage range for the R5F3650MNFB#U0?
The R5F3650MNFB#U0 operates at up to 32 MHz with a supply voltage range of 2.7 V to 5.5 V on both VCC1 and VCC2 pins. At 32 MHz, minimum instruction execution time is 31.25 ns under specified VCC conditions. The device supports wait and stop modes to reduce power consumption during idle periods.
Does the R5F3650MNFB#U0 support HDMI CEC functionality out of the box?
Yes, the R5F3650MNFB#U0 includes a dedicated CEC transceiver on pin P8_5 (NMI/SD/CEC), compliant with HDMI CEC standards. It provides built-in arbitration loss detection, automatic ACK generation, and 32 kHz baseband operation - requiring only external 100 Ω series resistor and pull-up to 3.3 V per HDMI specification.
How many analog input channels does the R5F3650MNFB#U0 support, and what is the ADC resolution?
The R5F3650MNFB#U0 integrates a 10-bit successive approximation A/D converter with 26 input channels, including sample-and-hold circuitry. Conversion time is 1.72 µs per sample, and inputs are accessible via ports P0_0–P0_7, P10_0–P10_7, P2_0–P2_7, and P9_7, supporting both single-ended and differential acquisition modes.
What debug interfaces are available on the R5F3650MNFB#U0?
The R5F3650MNFB#U0 features an on-chip debug interface supporting real-time tracing, breakpoint setting, and memory inspection via a standard JTAG or single-wire interface. It includes four address match interrupts and supports in-application flash rewriting - enabling firmware updates without removing the R5F3650MNFB#U0 from the target board.
Is the R5F3650MNFB#U0 pin-compatible with other members of the M16C/65 Group?
No - the R5F3650MNFB#U0 uses the 100-pin LQFP (PLQP0100KB-A) package and is not pin-compatible with 128-pin variants like R5F3651MNFC#U0. Within the 100-pin family, R5F3650MNFB#U0 shares pinout with R5F3650MNFA#U0 (same functions, different package type), but differs from earlier M16C/62 or M16C/63 derivatives.
