R5F72167FAUSH2A 概要
A 32-bit SuperH RISC microcontroller is a member of the Reduced Instruction Set Computer (RISC) family that executes most instructions in a single cycle. SuperH (SH) architecture from Renesas combines a compact 16-bit fixed-length instruction encoding with 32-bit internal registers, delivering high code density and deterministic interrupt latency. The SH-2A core adds DSP extensions, a hardware multiplier, and a Harvard bus for simultaneous instruction and data fetches, occupying the middle of Renesas's MCU taxonomy between the 8-bit RL78 and high-end RZ/A ARM Cortex-A application processors.
Key features of the R5F72167FAUSH2A include 768 KB on-chip flash, 48 KB on-chip SRAM, a 16-bit timer array (MTU2 and CMT), a 12-bit A/D converter with up to 8 channels, CAN, SCI, and I2C bus interfaces, and an operating voltage range of 3.0 V to 3.6 V. The device supports -40 C to +85 C ambient operation and offers a hardware multiplier plus multiply-accumulate unit for high-speed signal processing in motor control loops. According to the manufacturer datasheet, the SH7216 Group also includes advanced PWM outputs and encoder interfaces for servo and three-phase inverter control.
The R5F72167FAUSH2A uses Renesas's SuperH SH-2A CPU core with a 5-stage pipeline, enabling most instructions to execute in a single clock cycle at the rated 200 MHz internal frequency. On-chip debug and a trace buffer are accessible through a dedicated interface, allowing in-circuit emulation without expensive bond-out parts. The integrated CRC module, watchdog timer, and standby modes (sleep, software standby, and module stop) lower system power and improve functional safety diagnostics.
Typical applications include AC servo drives, three-phase inverter control, industrial PLCs, HVAC blower controllers, and automotive ECU body modules. The on-chip 12-bit ADC and multi-function timer pulse units (TPU) make it particularly well suited to Field-Oriented Control (FOC) of brushless DC and permanent-magnet synchronous motors. A wide operating temperature range and CAN bus interface also fit it for under-hood automotive and off-highway vehicle subsystems.
When designing with this device, pay close attention to decoupling: place a 0.1 uF ceramic bypass capacitor within 5 mm of each VCC/VSS pair, and add a bulk 10 uF or larger tantalum/ceramic capacitor near the analog supply pin to keep ADC readings clean. Use the on-chip flash programmer interface (single-wire or UART-boot) rather than socketed programming, as LQFP packages are not field-replaceable. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that go beyond what the manufacturer datasheet alone provides.

Three-Phase Motor Inverter Control
The R5F72167FAUSH2A's MTU2 complementary PWM timers and 12-bit ADC make it ideally suited to drive three-phase IGBT/MOSFET inverters for industrial servo and BLDC motor control. With a 200 MHz SH-2A core, the device executes Field-Oriented Control (FOC) loops within microseconds while leaving CPU headroom for communication and diagnostics. The on-chip 768 KB flash accommodates complex torque, speed, and position control algorithms, while 48 KB SRAM supports dual-shunt current sampling. According to Renesas application notes, the MTU2 dead-time generators prevent shoot-through on the inverter bridge. For new designs, pair the MCU with gate drivers such as the PDRV8343SPHPRQ1 to complete the power stage.

AC Servo Drive Position Control
Precision AC servo drives benefit from the R5F72167FAUSH2A's deterministic SuperH interrupt response and hardware DSP multiplier for high-speed PID and observer calculations. The MTU2 encoder interface captures quadrature signals directly from incremental encoders, offloading work from the CPU and enabling nanosecond-level edge timing accuracy. Combined with the 12-bit ADC's fast conversion rate, the controller closes position loops at rates above 20 kHz, suitable for CNC machinery and robotics. The -40 C to +85 C operating range and 3.3 V supply align with industrial cabinet environments. Renesas SH-2A libraries provide ready-to-port reference algorithms that shorten time-to-market for servo drive development.

Industrial PLC Controller
Compact industrial PLC controllers leverage the R5F72167FAUSH2A's 768 KB flash for IEC 61131-3 runtime and ladder-logic execution, plus 48 KB SRAM for variable storage and process image tables. The integrated CAN and SCI/UART interfaces connect directly to remote I/O and HMI panels, while the on-chip 12-bit ADC reads analog process variables such as temperature and pressure. With 200 MHz operation, the MCU scans typical PLC programs with deterministic cycle times under one millisecond. The lead-free LQFP package simplifies through-hole and SMT assembly on industrial-grade boards. The watchdog timer and module-standby modes improve functional safety and reduce idle power consumption for always-on factory installations.

HVAC Blower / Fan Motor Controller
HVAC blower and EC-fan controllers are an excellent fit for the R5F72167FAUSH2A's energy-efficient SuperH core and integrated motor-control peripherals. The MTU2 generates the complementary PWMs needed to drive single-phase or three-phase brushless fans with smooth torque and quiet operation. With 48 KB SRAM, the device can implement adaptive speed control and sensorless back-EMF detection algorithms without external memory. The 3.0-3.6 V supply range matches typical 24 V-to-3.3 V HVAC power rails. Built-in CAN support enables communication with building management systems, while the 12-bit ADC reads thermistor inputs for closed-loop temperature control.

Automotive Body / Chassis ECU
Although the R5F72167FAUSH2A is not AEC-Q100 qualified, its -40 C to +85 C operating range and CAN bus interface make it suitable for non-safety body electronics such as seat controllers, mirror modules, and lighting drivers. The 768 KB flash accommodates CANopen and J1939 protocol stacks, while the 12-bit ADC reads potentiometer inputs for position feedback. The MTU2 timers generate PWM signals for LED dimming and small DC motor control with smooth transitions. Lead-free LQFP packaging supports automated assembly lines typical of automotive tier-1 suppliers. For safety-critical ECUs, consider AEC-Q100 qualified alternatives from the RH850 or RX family.
おすすめ
Solar Inverter Control Board
Solar inverter controllers use the R5F72167FAUSH2A to execute MPPT algorithms and synchronize grid-tie waveforms with the utility network. The SuperH SH-2A core's DSP extensions accelerate trigonometric calculations required for phase-locked loops and reactive power compensation. The MTU2's complementary PWM outputs drive the IGBT bridge at switching frequencies from 16 to 32 kHz, while dead-time insertion is handled in hardware to prevent shoot-through. With 48 KB SRAM, the controller maintains grid-monitoring buffers and frequency-domain data without external memory. CAN connectivity allows the inverter to participate in plant-wide energy management systems.

設計ノート
The R5F72167FAUSH2A's analog and digital VCC rails share the same 3.3 V supply but require separate decoupling. Place a 0.1 uF ceramic bypass capacitor within 5 mm of each VCC/VSS pin pair, and add a 10 uF bulk ceramic or tantalum capacitor near the AVCC pin to keep the 12-bit ADC readings clean. Route AVCC traces away from the MTU2 PWM outputs and high-current gate-driver returns to avoid switching-noise coupling into ADC samples.
Estimated: at 200 MHz operation with 3.3 V supply and typical peripheral activity, the SH7216 device dissipates around 350 mW internally. The LQFP (FAU) package typically has a theta_JA around 40-50 C/W on a 4-layer JEDEC test board. With 1 square inch of top-side copper, this falls to roughly 35 C/W. For continuous full-load operation above 70 C ambient, provide thermal relief copper or consider a small heatsink for margin.
Use a 4-layer PCB with continuous ground and power planes for the SH7216. Keep crystal traces (system clock and RTC) within 8 mm of the MCU and surround them with a guard ground trace tied to the GND plane. Provide test points for the mode-control pins (MD0, MD1) to enable in-circuit programming without rework. Route the MTU2 complementary PWM outputs as matched-length differential pairs to the gate driver to avoid PWM skew.
Do not assume all SH7216 Group parts share identical flash programming protocols - check the design-step suffix (e.g., '2A') against your flash writer's support list before committing to production. The lead-free 'H' suffix requires Pb-free reflow profiles peaking at 245-260 C, not the legacy 220 C SnPb profile. Do not enable on-chip debug's trace buffer during motor-control loops, as the trace DMA can starve the MTU2 of bus bandwidth and corrupt PWM timing.
