Product details
Overview
R5F72395BDFP#H0 from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A CPU core, featuring 1.5 MB on-chip Flash memory, 128 KB RAM, and integrated peripherals including CAN controller, SCI, I²C, MTU, and ADC. It operates at up to 100 MHz and targets automotive body control modules requiring real-time deterministic response.
For engineers reviewing the R5F72395BDFP#H0 datasheet, R5F72395BDFP#H0 pinout, R5F72395BDFP#H0 application, or R5F72395BDFP#H0 equivalent, key selection criteria include Flash endurance (100k write/erase cycles), CAN 2.0B compliance, -40°C to +125°C operating temperature, and support for single-chip mode with external bus interface disabled.
Technical Context
The R5F72395BDFP#H0 implements the SH-2A core with FPU extension, enabling IEEE 754-compliant single-precision floating-point operations. Its CPG supports multiple clock sources - crystal resonator (4–20 MHz), external clock input, or PLL multiplication - with programmable dividers for peripheral clock domain partitioning.
Interrupt handling uses a 16-level priority INTC with vector table relocation via VBR register; exception vectors are fixed at 0x00000000 in single-chip mode. The device integrates a 12-bit, 24-channel ADC with sample-and-hold and hardware-triggered conversion sequencing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F72394BDFP#H0 | Same SH-2A core and package; reduced Flash (1 MB) and RAM (96 KB); no FPU | Suitable for cost-sensitive body control where floating-point math is not required | Select when application does not require IEEE 754 computation or has lower memory footprint needs |
| RA6M4GFP120A001 | Arm® Cortex®-M4F core, 2 MB Flash, 384 KB RAM, 12-bit ADC (24 ch), one CAN FD channel | Better suited for new designs requiring CAN FD, TrustZone security, or higher memory scalability | Choose for next-gen platforms needing CAN FD, cryptographic acceleration, or longer product lifecycle roadmap |
Compared with R5F72395BDFP#H0, the R5F72394BDFP#H0 offers identical pinout and peripheral set but omits FPU and reduces memory - ideal for legacy-compatible cost-down. The RA6M4GFP120A001 provides modern Arm architecture and CAN FD but requires PCB redesign and toolchain migration.

No, the R5F72395BDFP#H0 supports only CAN 2.0B protocol (ISO 11898-1:2003). It features two fully independent CAN controllers with message RAM, filtering, and error handling logic, but lacks CAN FD framing, bit-rate switching, or extended data length support. For CAN FD, consider Renesas' RA6M4 or RH850/F1K families.
What debug interface does the R5F72395BDFP#H0 use?
The R5F72395BDFP#H0 uses the standard Renesas E1/E20 emulator interface via the 14-pin JTAG connector (pins 1–14 on CN1 of typical evaluation boards). It supports full-speed real-time debugging, flash programming, and trace via the on-chip debug module (OCDS), compatible with Renesas CS+ and e2 studio IDEs.
Is the R5F72395BDFP#H0 qualified for automotive applications?
Yes, the R5F72395BDFP#H0 is AEC-Q100 Grade 2 qualified (-40°C to +125°C) and designed for automotive body electronics. It includes built-in diagnostic features such as clock oscillation stop detection, voltage monitor, and temperature sensor - supporting ASIL-B development when used with appropriate software safety mechanisms.
What is the Flash memory endurance specification for the R5F72395BDFP#H0?
The on-chip Flash memory in the R5F72395BDFP#H0 is rated for 100,000 write/erase cycles per sector, as specified in Renesas' SH7239 Group Hardware User's Manual Rev. 2.00.
