Renesas R5F35623DFE#U0

Overview

R5F35623DFE from Renesas is an 80-pin LQFP 16-bit microcontroller in the M16C/56D Group, featuring a M16C/60 Series CPU core, 96 KB program ROM 1, 16 KB RAM, 8 KB data flash, and operation at up to 32 MHz (3.0–5.5 V). It integrates UART0–UART3, I²C-bus, 16-bit timers (A/B/S), A/D converter (10-bit × 16 channels), DMAC (4-channel), and real-time clock - designed for industrial equipment control and office automation systems.

For engineers reviewing the R5F35623DFE datasheet, R5F35623DFE pinout, R5F35623DFE application, or R5F35623DFE equivalent, key selection criteria include its 80-pin PLQP0080KB-A package, absence of CAN interface (distinguishing it from M16C/5LD variants), 16-bit timer count, UART channel count (4 total), and operating temperature range (−40°C to +85°C).

Technical Context

The R5F35623DFE implements the M16C/60 Series CPU core with 91 basic instructions, 16×16-bit multiplier, and multiply-accumulate unit. It supports single-chip mode only and executes instructions in as little as 31.25 ns at 32 MHz with 3.0–5.5 V supply.

Its peripheral set includes four UART channels (UART0–UART3), one multi-master I²C-bus interface, 16-bit Timer A (×5), Timer B (×3), Timer S (×1 base + 8 I/O channels), three-phase motor control timer (using TA1/TA2/TA4/B2), on-chip dead time timer, and dual A/D converters (10-bit × 16 + 10-bit × 4 channels).

FAQ

What is the maximum operating frequency and voltage range for the R5F35623DFE?

The R5F35623DFE operates at up to 32 MHz with a supply voltage of 3.0 to 5.5 V, and also supports 25 MHz operation down to 2.7 V. Its minimum instruction execution time is 31.25 ns at 32 MHz, enabling high-speed deterministic control loops in motor and power applications. The R5F35623DFE maintains full functionality across this voltage range without internal regulator constraints.

Does the R5F35623DFE include a CAN interface?

No, the R5F35623DFE does not include a CAN module. It belongs to the M16C/56D Group, which omits CAN functionality. In contrast, the M16C/5LD Group (e.g., R5F35L23DFE) includes a 32-slot CAN message buffer. The R5F35623DFE provides UART, I²C, and three-phase motor control peripherals instead - making it suitable for applications where CAN is not required.

How many A/D converter channels does the R5F35623DFE support, and what is their resolution?

The R5F35623DFE integrates two A/D converter blocks: a primary 10-bit A/D circuit with 16 input channels (AN0_0–AN0_3, AN2_0–AN2_3, AN3_0–AN3_2, AN_0–AN_7), and a secondary 10-bit A/D1 circuit with 4 dedicated channels. Both operate at 10-bit resolution with separate reference inputs (VREF, AVCC/AVSS), supporting simultaneous sampling for multi-sensor industrial monitoring without external multiplexers.

What package type and pin count does the R5F35623DFE use?

The R5F35623DFE uses an 80-pin plastic LQFP package designated PLQP0080KB-A (previously coded 80P6Q-A), measuring 14 mm × 14 mm with 0.65 mm lead pitch. This package is RoHS-compliant and optimized for reflow soldering. Pin assignments match the M16C/56D Group 80-pin block diagram and are fully documented in Tables 1.7–1.8 of the R01DS0132EJ0120 datasheet.

What debug and programming features are supported on the R5F35623DFE?

The R5F35623DFE supports on-board flash rewrite via on-chip debugger, with four address match breakpoints for real-time code inspection. It includes ROM code protection and ID code verification to prevent unauthorized firmware access. Programming and erasure endurance is rated at 1,000 cycles for program ROM and 10,000 cycles for data flash - enabling field firmware updates and parameter logging in deployed R5F35623DFE systems.
