Product details
Overview
R5F72866N100FP#U2 from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A core, featuring 1 MB of on-chip Flash memory, 128 KB RAM, and integrated peripherals including USB 2.0 FS host/device, CAN controller, multiple SCI/UART channels, and 12-bit ADC. It operates at up to 100 MHz and targets industrial motor control and factory automation systems requiring deterministic real-time response.
For engineers reviewing the R5F72866N100FP#U2 datasheet, R5F72866N100FP#U2 pinout, R5F72866N100FP#U2 application, or R5F72866N100FP#U2 equivalent, key selection criteria include its 100-pin LQFP package, dual CAN interface with time-triggered communication support, USB 2.0 full-speed capability without external PHY, and integrated CPG with PLL for flexible clock generation across multiple domains (CPU, peripheral, USB).
Technical Context
The R5F72866N100FP#U2 implements the SH-2A CPU core with FPU support, executing instructions in a five-stage pipeline with branch prediction. Its system architecture integrates a bus controller (BSC) supporting external memory expansion up to 64 MB, a data transfer controller (DTC) enabling autonomous DMA transfers between peripherals and memory without CPU intervention, and an interrupt controller (INTC) with 128 interrupt sources and programmable priority levels.
Peripheral integration includes two independent CAN controllers compliant with ISO 11898-1:2003, each supporting 32 message objects and configurable FIFO modes; a 12-bit, 24-channel ADC with conversion times as low as 1.2 μs; and six 16-bit timer units (MTU2S) supporting PWM generation, input capture, and dead-time insertion for three-phase inverter control.

FAQ
What is the maximum operating frequency of the R5F72866N100FP#U2?
The R5F72866N100FP#U2 operates at a maximum CPU frequency of 100 MHz, achieved using its integrated Clock Pulse Generator (CPG) with PLL. This frequency is sustained under full load within the specified −40°C to +85°C ambient temperature range and requires proper decoupling and thermal management. The R5F72866N100FP#U2's SH-2A core delivers 1.35 DMIPS/MHz, resulting in ~135 DMIPS total performance for real-time control tasks.
Does the R5F72866N100FP#U2 include an integrated USB transceiver?
Yes, the R5F72866N100FP#U2 integrates a full-speed USB 2.0 transceiver compliant with USB Specification Revision 2.0. It supports both host and device modes without requiring an external PHY, and includes internal pull-up resistors and voltage regulators for VBUS sensing. This capability is confirmed in the SH7280 Group Hardware User's Manual Rev. 3.00 and enables direct USB connectivity for firmware updates, configuration, and HMI communication in the R5F72866N100FP#U2.
What peripheral interfaces does the R5F72866N100FP#U2 support for industrial networking?
The R5F72866N100FP#U2 supports dual CAN 2.0B controllers with time-triggered communication capability, six serial communication interfaces (SCI) configurable as UART, LIN, or IrDA, and a USB 2.0 full-speed interface. It does not include an on-chip Ethernet MAC - that feature appears only in the R5F72867N100FP#U2 variant. These interfaces allow the R5F72866N100FP#U2 to serve as a protocol gateway or distributed controller in CANopen, DeviceNet, or custom industrial networks.
Is the R5F72866N100FP#U2 qualified for automotive applications?
No, the R5F72866N100FP#U2 is classified as a "Standard" quality grade device per Renesas documentation, intended for industrial applications such as motor drives and PLCs. It is not AEC-Q100 qualified and lacks the extended temperature range (−40°C to +125°C), enhanced ESD immunity, or automotive-specific failure-in-time (FIT) metrics required for automotive use. For automotive-grade equivalents, consult Renesas' RH850 or RL78/F1x families instead of the R5F72866N100FP#U2.
What debug interface is supported by the R5F72866N100FP#U2?
The R5F72866N100FP#U2 supports the standard Renesas E2000/E2 emulator interface via the 14-pin JTAG connector (pin-compatible with IEEE 1149.1). Debugging includes full hardware breakpoints, real-time trace via the on-chip trace buffer, and flash programming through the built-in bootloader. This interface is documented in Section 1.4 (Pin Functions) and Appendix A of the SH7280 Group Hardware User's Manual, and is fully supported by Renesas' CS+ and e2 studio IDEs for the R5F72866N100FP#U2.
