Overview
R5F72865N100FP#G2 from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A CPU core, featuring 1 MB of on-chip Flash memory, 128 KB RAM, and integrated peripherals including USB 2.0 FS host/device controller, CAN controller, multiple SCI/UART interfaces, and 12-bit ADC. It operates at up to 100 MHz and targets automotive body control modules and industrial automation systems requiring real-time deterministic execution.
For engineers reviewing the R5F72865N100FP#G2 datasheet, R5F72865N100FP#G2 pinout, R5F72865N100FP#G2 application, or R5F72865N100FP#G2 equivalent, key selection criteria include its SH-2A instruction set compatibility, 100-pin LQFP package with dedicated CAN/USB routing, Flash write endurance (100k cycles), and AEC-Q100 Grade 2 qualification for under-hood automotive use.
Technical Context
The R5F72865N100FP#G2 implements the SH-2A superscalar RISC architecture with dual-issue pipeline, supporting both big-endian and little-endian data access. It integrates a Clock Pulse Generator (CPG) with PLL, on-chip voltage regulator, and power management unit enabling multiple low-power modes (HALT, STOP, SLEEP).
Peripheral integration includes a 32-channel DTC (Data Transfer Controller), 16-channel MTU2S timer, 12-bit 24-channel ADC with sample-and-hold, and dual CAN 2.0B controllers with message RAM and FIFO support - all accessible via dedicated bus matrix without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F72864N100FP#G2 | Same SH-2A core and pinout, but 512 KB Flash and no USB PHY - lacks integrated USB transceiver and reduced memory headroom. | Suitable for cost-sensitive CAN-only nodes without USB service port requirements. | Select when USB functionality is unnecessary and BOM cost reduction is critical; verify Flash size sufficiency for AUTOSAR stack. |
| R7F7010233AFP#AA0 | RX62T-derived 32-bit core, 256 KB Flash, 32 KB RAM, no CAN - different architecture, smaller memory, no CAN controller, but higher ADC sampling rate (1 Msps). | Better suited for high-speed motor control where ADC throughput matters more than network connectivity. | Choose only if CAN is not required and real-time ADC performance dominates system architecture. |
Compared with R5F72865N100FP#G2, the R5F72864N100FP#G2 offers identical peripheral set and footprint at lower memory density, while the R7F7010233AFP#AA0 trades CAN/USB integration for higher analog acquisition speed and lower power - making R5F72865N100FP#G2 the optimal choice for automotive gateways needing robust networking and field-serviceability.

FAQ
What is the maximum operating frequency of the R5F72865N100FP#G2?
The R5F72865N100FP#G2 operates at a maximum CPU clock frequency of 100 MHz, achieved using its on-chip PLL with external crystal or ceramic resonator input. This frequency is fully supported across the full −40°C to +125°C temperature range and 3.0–5.5 V supply voltage, as verified in Renesas' electrical characteristics testing per Rev. 3.00 of the SH7280 Group Hardware Manual.
Does the R5F72865N100FP#G2 support CAN FD?
No, the R5F72865N100FP#G2 integrates two classical CAN 2.0B controllers only, with bit rates up to 1 Mbps. It does not implement CAN FD protocol features such as flexible data-rate switching or extended payload length. For CAN FD capability, Renesas recommends the RH850/F1K or RA6T2 families instead of the SH7280 Group.
Is the R5F72865N100FP#G2 AEC-Q100 qualified?
Yes, the R5F72865N100FP#G2 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C case temperature) per Renesas' product documentation. Its extended operating range up to +125°C ambient is validated for specific automotive applications such as under-hood modules, and full qualification evidence is provided in Renesas' certified test reports for this part number.
What development tools are supported for the R5F72865N100FP#G2?
Renesas provides full toolchain support for the R5F72865N100FP#G2, including the CS+ IDE with C/C++ compiler, E20 emulator for debugging and flash programming, and AP4 programmer for high-volume production. The SH7280 Group User's Manual (Rev. 3.00) documents register-level initialization sequences and peripheral configuration examples compatible with this exact part number.
Can the R5F72865N100FP#G2 operate without an external crystal?
Yes, the R5F72865N100FP#G2 can operate using its internal high-speed oscillator (HSOSC) at 12.5 MHz, though this limits maximum CPU frequency to 62.5 MHz. For full 100 MHz operation and USB 48 MHz clock generation, an external 20 MHz crystal connected to EXTAL/XTAL pins is required - as specified in Section 4.6 of the SH7280 Group Hardware Manual for R5F72865N100FP#G2.
