Renesas R5F72167ADFA#V1

Overview

R5F72167ADFA#V1 from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A core, featuring 1 MB Flash memory, 128 KB RAM, and integrated peripherals including CAN, SCI, I²C, and 12-bit ADC. It operates at up to 100 MHz and targets real-time industrial control applications requiring deterministic timing and robust peripheral integration.

For engineers reviewing the R5F72167ADFA#V1 datasheet, R5F72167ADFA#V1 pinout, R5F72167ADFA#V1 application, or R5F72167ADFA#V1 equivalent, this page delivers verified hardware specifications, validated package mapping (LQFP-144), confirmed peripheral register-level behavior, and cross-referenced alternative MCUs for migration or second-sourcing in motor control, PLC, and embedded HMI designs.

Technical Context

The R5F72167ADFA#V1 implements the SH-2A CPU core with FPU support, executing instructions in a five-stage pipeline with branch prediction. It integrates a Clock Pulse Generator (CPG) supporting multiple clock sources - crystal resonator (1–20 MHz), external clock input, and internal oscillator - with programmable PLL for core and peripheral clock domain derivation.

System-level features include a Data Transfer Controller (DTC) for autonomous memory-to-peripheral transfers, an Interrupt Controller (INTC) with 128 interrupt sources and priority levels, and a Bus State Controller (BSC) enabling flexible external memory interface configuration for SRAM, NOR Flash, or FPGA co-processor expansion.

FAQ

What is the maximum operating frequency of the R5F72167ADFA#V1?

The R5F72167ADFA#V1 operates at a maximum CPU frequency of 100 MHz, achieved via its integrated PLL clock generator configured from an external crystal (1–20 MHz) or external clock source. This frequency applies to the SH-2A core and associated bus matrix; peripheral clocks (e.g., CAN, ADC) are derived independently via prescalers and may run at lower rates to meet timing specifications.

Does the R5F72167ADFA#V1 support CAN FD?

No, the R5F72167ADFA#V1 supports only Classical CAN 2.0B (ISO 11898-1) with bit rates up to 1 Mbps. It does not implement CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. For CAN FD capability, Renesas offers later-generation RH850 or RA-family MCUs - the R5F72167ADFA#V1's CAN controllers are strictly legacy-compliant.

What debug interface does the R5F72167ADFA#V1 provide?

The R5F72167ADFA#V1 supports on-chip debugging via the E10A-USB emulator interface using the dedicated TDI, TDO, TCK, TMS, and TRST pins compliant with IEEE 1149.1 (JTAG). It does not support SWD or Serial Wire Debug; JTAG is required for full visibility into CPU state, memory, and peripheral registers during development and validation of R5F72167ADFA#V1-based systems.

Is the R5F72167ADFA#V1 qualified for automotive applications?

No, the R5F72167ADFA#V1 is rated for Industrial grade (−40°C to +85°C) and classified as "Standard" quality per Renesas documentation. It is not AEC-Q100 qualified and lacks automotive-specific features such as enhanced ESD immunity, extended temperature screening, or fault collection mechanisms required for passenger vehicle ECUs. Its intended use is factory automation, not automotive powertrain or body control.

How is Flash memory protected against unauthorized access on the R5F72167ADFA#V1?

Flash protection on the R5F72167ADFA#V1 is implemented via a 32-bit security ID register and read-out protection bit. When enabled, it prevents external readback of Flash contents through the debug interface and disables mass erase commands. Protection is irreversible without chip erase - once activated, the R5F72167ADFA#V1 requires full Flash blanking to re-enable programming, ensuring firmware intellectual property remains secured in deployed units.
