Product details
Overview
R5F35633DFF#U0 from Renesas is a 16-bit M16C/56D Group microcontroller in 64-pin LQFP (PLQP0064KB-A), featuring the M16C/60 Series CPU core, 96 KB program ROM 1, 16 KB RAM, 4 KB × 2 blocks data flash, and operation at 32 MHz / 3.0–5.5 V for industrial control and office equipment.
For engineers reviewing the R5F35633DFF#U0 datasheet, R5F35633DFF#U0 pinout, R5F35633DFF#U0 application, or R5F35633DFF#U0 equivalent, key selection criteria include its 55 CMOS I/O ports, 70 interrupt vectors, 4-channel DMAC, 16-bit timers (A×5, B×3, S×1), and UART/serial interface configuration without CAN support.
Technical Context
The R5F35633DFF#U0 implements the M16C/60 Series CPU core with 16×16-bit multiplier and multiply-accumulate unit, executing instructions in as little as 31.25 ns at 32 MHz. It operates exclusively in single-chip mode with no external bus interface.
Its peripheral set includes four UART/clock-synchronous serial interfaces (UART0–UART3), one multi-master I²C-bus channel, 10-bit A/D converters (16 channels on A/D circuit + 4 on A/D1 circuit), CRC calculator (CCITT/CRC-16), watchdog timer with dedicated 125 kHz on-chip oscillator, and real-time clock with week-level calendar support.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F35623DFE | 80-pin LQFP package, 96 KB ROM, same peripheral set but adds UART4 and 27-channel A/D | Suitable where extra serial interface or analog inputs are needed; not pin-compatible due to package size | Select when board layout allows larger footprint and higher I/O count is required |

FAQ
What is the maximum operating frequency and voltage range for the R5F35633DFF#U0?
The R5F35633DFF#U0 operates at up to 32 MHz with a supply voltage range of 3.0 V to 5.5 V. At 25 MHz, it supports down to 2.7 V. These ratings are specified across the full industrial temperature range (−40°C to +85°C), enabling deployment in demanding environments without derating.
Does the R5F35633DFF#U0 include a CAN interface?
No, the R5F35633DFF#U0 does not include a CAN module. It belongs to the M16C/56D Group, which omits CAN functionality. The M16C/5LD Group (e.g., R5F35L33DFF) provides identical packaging and memory but adds a 32-slot CAN message buffer-confirm part number suffix and group designation before design-in.
How many analog-to-digital converter channels does the R5F35633DFF#U0 support?
The R5F35633DFF#U0 supports 20 total 10-bit A/D input channels: 16 on the primary A/D circuit and 4 on the A/D1 circuit. These are distributed across port pins including AN0_0–AN0_3, AN_0–AN_7, AN2_4, and AN3_0–AN3_2, with shared pin functionality requiring careful multiplexing in firmware.
What debug features are integrated into the R5F35633DFF#U0?
The R5F35633DFF#U0 includes on-board flash rewrite capability and four address match breakpoints for non-intrusive debugging. These features allow firmware updates in-system and precise code execution analysis without requiring external JTAG emulators-reducing development tooling cost and test complexity.
Is the R5F35633DFF#U0 pin-compatible with other members of the M16C/56D Group?
Yes, all 64-pin M16C/56D Group variants-including R5F35630DFF, R5F35633DFF, and R5F35636DFF-share the PLQP0064KB-A package and identical pinout. Memory size differences (64 KB / 96 KB / 128 KB ROM) do not affect electrical or mechanical compatibility, enabling scalable firmware reuse across product tiers.
