Product details
Overview
R5F3650TDFA#U0 from Renesas is a 16-bit M16C/60 Series CPU core microcontroller with 768 KB program ROM, 16 KB RAM, and 47 KB data flash, operating at up to 32 MHz (2.7–5.5 V), featuring integrated A/D (10-bit × 26 ch), D/A (8-bit × 2), CEC, three-phase motor control timers, and real-time clock - deployed in HDMI-CEC-enabled consumer audio/video systems.
For engineers reviewing the R5F3650TDFA#U0 datasheet, R5F3650TDFA#U0 pinout, R5F3650TDFA#U0 application, or R5F3650TDFA#U0 equivalent, key selection criteria include its 100-pin QFP package (PRQP0100JD-B), -40°C to +85°C industrial temperature grade, CEC transceiver support at 32 kHz, and dual-voltage bus interface (VCC1/VCC2) for mixed-signal system integration.
Technical Context
The R5F3650TDFA#U0 implements the M16C/60 CPU core with 16×16-bit multiplier and MAC instruction, enabling deterministic real-time motor control and signal processing. Its peripheral set includes six 16-bit Timer B units for pulse width/period measurement and three-phase inverter timing with on-chip dead time generation.
It integrates dual-clock domain operation: main/sub crystal oscillators, 125 kHz low-speed on-chip oscillator, 40 MHz ±10% high-speed on-chip oscillator, and PLL frequency synthesizer - supporting simultaneous RTC, CEC (32 kHz), and UART/I²C communication without external timing components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F3650TDFB#U0 | Same silicon, PLQP0100KB-A LQFP package (0.5 mm pitch) instead of PRQP0100JD-B QFP (0.65 mm pitch) | Requires PCB redesign due to different footprint and thermal pad; identical functionality and timing | Select when higher pin density and improved thermal performance are prioritized over legacy QFP compatibility |
| R5F3651TDFC#U0 | 128-pin LQFP variant with identical memory (768 KB/16 KB/47 KB) but extended I/O count (111 vs. 85 CMOS ports) | Suitable for designs needing additional GPIO, UARTs, or external bus width beyond 100-pin limits | Choose when system scalability requires more peripheral resources without changing firmware architecture |
Compared with R5F3650TDFA#U0, the R5F3650TDFB#U0 offers identical electrical behavior in a finer-pitch LQFP, while R5F3651TDFC#U0 provides expanded I/O and bus capability in a larger 128-pin package - both retain full software compatibility but differ in physical integration requirements.

FAQ
What is the operating temperature range for the R5F3650TDFA#U0?
The R5F3650TDFA#U0 is rated for -40°C to +85°C operation, validated per industrial-grade specifications. This range ensures reliable performance in demanding environments such as enclosed AV equipment cabinets and factory-floor motor controllers where ambient temperatures exceed commercial limits. The device's anti-noise design further enhances stability under thermal stress.
Does the R5F3650TDFA#U0 support HDMI CEC functionality natively?
Yes, the R5F3650TDFA#U0 includes dedicated on-die CEC circuitry compliant with HDMI CEC standards, including transmit/receive, arbitration loss detection, and automatic ACK generation at 32 kHz. Pin P8_5 serves as the bidirectional CEC I/O, eliminating the need for external CEC transceivers in compliant designs.
What package type and pin count does the R5F3650TDFA#U0 use?
The R5F3650TDFA#U0 uses a 100-pin QFP package designated PRQP0100JD-B (formerly 100P6F-A), with 0.65 mm lead pitch and RoHS-compliant lead finish. This package is distinct from the 100-pin LQFP variant (PLQP0100KB-A) used in the R5F3650TDFB#U0, requiring separate PCB layout.
How many A/D converter channels does the R5F3650TDFA#U0 provide, and what is their resolution?
The R5F3650TDFA#U0 integrates a 10-bit successive-approximation A/D converter with 26 input channels, including sample-and-hold capability. Channels are distributed across multiple port groups (e.g., AN0_0–AN0_7, AN1–AN7, ANEX0/ANEX1) and support simultaneous sampling for multi-sensor monitoring in motor control or power supply supervision.
Can the R5F3650TDFA#U0 execute code from external memory?
Yes, the R5F3650TDFA#U0 supports external bus expansion with 1 MB base address space extendable to 4 MB, configurable wait states (0–8), four chip select outputs, and selectable bus format (multiplexed/separate). This enables execution from external NOR flash or SRAM when internal 768 KB ROM is insufficient for complex application firmware.
