Product details
Overview
R5F3650TNFB#10 from Renesas is a 16-bit M16C/65 microcontroller with 512 KB Flash ROM, 32 KB RAM, 10-bit ADC (26 channels), 8-bit DAC (2 channels), and integrated intelligent I/O timers supporting PWM, encoder input, and inverter control. It operates at up to 50 MHz across 3.0–5.5 V and targets industrial motor control and embedded automation systems.
For engineers reviewing the R5F3650TNFB#10 datasheet, R5F3650TNFB#10 pinout, R5F3650TNFB#10 application, or R5F3650TNFB#10 equivalent, key selection criteria include its 50 MHz R32C/100 core execution speed, 4-channel DMACII with full peripheral interrupt startup capability, 10-bit × 26-channel ADC with sample-and-hold, and PLQP0100KB-A 100-pin LQFP package with 5V-tolerant inputs.
Technical Context
The R5F3650TNFB#10 implements the R32C/100 CPU core with 108 basic instructions and 20 ns minimum instruction execution time at 50 MHz. Its clock system integrates four independent sources: main clock, PLL, subclock (125 kHz), and on-chip oscillator, enabling flexible low-power and high-precision timing modes.
Peripheral integration includes dual UARTs with multi-master I²C support, 11-channel 16-bit timer group (TimerA/TimerB), 24-channel intelligent I/O for PWM and event counting, and dedicated hardware for 3-phase inverter control with dead-time insertion - all coordinated via DMACII for autonomous data movement without CPU intervention.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F64165DFB | Same R32C/100 core, identical PLQP0100KB-A package, but 384 KB Flash + 40 KB RAM vs. 512 KB + 32 KB | Suitable for cost-sensitive motor control where reduced Flash suffices for fixed-function firmware | Select when firmware size < 384 KB and higher RAM not required; shares same pinout and peripheral set |

FAQ
What is the maximum operating frequency of the R5F3650TNFB#10?
The R5F3650TNFB#10 operates at a maximum frequency of 50 MHz using its on-chip PLL with external crystal input. This is achieved with a 20 ns minimum instruction execution time on the R32C/100 core. The device also supports lower-speed modes (e.g., 125 kHz subclock) for ultra-low-power standby operation - all configurable via the clock generation circuit registers in the R5F3650TNFB#10 datasheet.
Does the R5F3650TNFB#10 include an integrated real-time clock (RTC)?
No, the R5F3650TNFB#10 does not include a hardware RTC module. While it supports subclock operation (125 kHz) for low-power timing, it lacks dedicated calendar registers, alarm functions, or battery-backed timekeeping. For RTC functionality, designers must implement external RTC ICs or use software-based timekeeping driven by the subclock - unlike variants such as R5F64176DFB which integrate full RTC capability.
How many ADC channels does the R5F3650TNFB#10 support, and what is their resolution?
The R5F3650TNFB#10 supports 26 analog input channels with 10-bit resolution and integrated sample-and-hold circuitry. All 26 channels are accessible via dedicated AD0–AD25 pins and can be scanned in sequence or triggered by external events. This configuration enables simultaneous sampling across multiple sensors - a key requirement in energy metering and motor phase current monitoring applications using the R5F3650TNFB#10.
Is the R5F3650TNFB#10 pin-compatible with other M16C/65 family members?
Yes, the R5F3650TNFB#10 uses the PLQP0100KB-A 100-pin LQFP package shared across multiple M16C/65 devices including R5F64165DFB and R5F64176DFB. Pin assignments for power, clocks, reset, and core peripherals are identical. However, some variant-specific functions (e.g., RTC pins on R5F64176DFB) are No Connect on the R5F3650TNFB#10 - confirming mechanical and electrical pin compatibility for drop-in replacement in most designs.
What development tools are officially supported for the R5F3650TNFB#10?
Renesas provides official support for the R5F3650TNFB#10 through the HEW (High-performance Embedded Workshop) IDE and the E8a/E10A-USB debug emulators. These tools enable full C/C++ debugging, Flash programming, and real-time trace via the on-chip debug interface. Renesas also publishes application notes covering motor control libraries and ADC calibration routines specific to the R5F3650TNFB#10 and related M16C/65 devices.
