R5F72167FPU Descripción general
Key features include a SuperH SH-2A 32-bit RISC core with built-in FPU for single-precision IEEE 754 floating-point operations, 1 MB (1M x 8) program flash, 32 KB SRAM, and a rich set of on-chip peripherals. The device integrates multiple serial interfaces, a 12-bit ADC, motor-control timers (MTU2), and a hardware multiply/accumulate unit, making it suitable for computationally demanding control loops.
The SH-2A architecture belongs to the SuperH family of RISC microcontrollers developed by Hitachi and continued by Renesas. It uses a fixed 16-bit instruction encoding with 32-bit extensions, delivering high code density and deterministic pipeline behaviour. The integrated FPU eliminates the need for software floating-point emulation, allowing real-time DSP-style algorithms to execute within microseconds rather than milliseconds.
Typical applications include industrial motor control (servo drives, AC inverter control), factory automation controllers, automotive body and powertrain subsystems, and precision mechatronics such as robotics and CNC machines. The combination of deterministic interrupt latency, hardware FPU, and rich timer peripherals makes it ideal for closed-loop torque and speed regulation.
When designing with this device, ensure the firmware stack is built for the SuperH-2A instruction set and uses the Renesas HEW or e2 studio toolchain. The 176-pin LQFP package requires careful PCB layout for the high-speed oscillator traces, and decoupling capacitors should be placed as close as possible to every VCC/VSS pair to handle the core's switching current.

Aplicaciones típicas
R5F72167FPU es adecuado para 6 aplicacións: Industrial Servo Drive Control, AC Inverter and Variable-Frequency Drive, Industrial Robot and CNC Machine Controller, Automotive Body and Powertrain ECU, Renewable Energy Solar Inverter Controller, Precision Mechatronics and Medical Equipment.
Industrial Servo Drive Control
The R5F72167FPU drives industrial servo amplifiers where 200 MHz SH-2A FPU throughput keeps current-loop PI regulators inside 20 kHz PWM cycles. The MTU2 timer unit emits complementary PWM with hardware dead-time insertion, while the on-chip 12-bit ADC and hardware trigger sampling provide deterministic phase-current measurement. Compared with Cortex-M motor MCUs, the deterministic SuperH interrupt latency and integrated FPU remove software-emulation jitter in field-oriented control loops and deliver motor-control bandwidth without DSP cost.
Recomendado
AC Inverter and Variable-Frequency Drive
The R5F72167FPU is widely used in low-voltage AC inverter drives for HVAC, pumps, and fans because the SH-2A core can execute a complete V/Hz or sensorless vector-control loop in a 100-microsecond control tick. The integrated FPU accelerates slip-frequency estimation and Clarke/Park inverses, while the motor-control timer unit produces multi-channel PWM for three-phase IGBT bridges. Industrial-grade 176-pin LQFP packaging supports conformal-coated boards inside sealed inverter cabinets operating from -40 C to +85 C ambient.
Recomendado
Industrial Robot and CNC Machine Controller
The R5F72167FPU executes multi-axis trajectory planning in CNC machines and six-axis robots, where path interpolation, jerk-limited profile generation, and forward kinematics are computed every 1-4 milliseconds. The 1 MB program flash stores complex motion libraries while 32 KB SRAM retains real-time state. EtherCAT or CANopen slave stacks run on its SCI channels and the on-chip FPU computes inverse-kinematics at full servo update rate, eliminating the need for an additional DSP coprocessor.
Recomendado
Automotive Body and Powertrain ECU
The R5F72167FPU serves in automotive body controllers where deterministic real-time response is required for ECU multiplexing, CAN bus processing, and sensor-fusion calculations. Its SuperH-2A FPU executes powertrain diagnostics with single-precision accuracy, while multiple SCI channels handle CAN, LIN, and K-Line communications. Although not AEC-Q100 qualified for the FPU suffix, the SH2A family is widely deployed in automotive aftermarket body modules and industrial vehicle dashboards through wide-temperature-range variants of the same die.
Recomendado
Renewable Energy Solar Inverter Controller
The R5F72167FPU controls string-inverter power stages in solar PV installations where maximum-power-point tracking (MPPT) and grid-synchronisation calculations must run in real time. The 200 MHz core with hardware FPU executes perturb-and-observe or incremental-conductance MPPT algorithms inside 10-millisecond tracking loops, while the on-chip timers generate grid-tie inverter PWM. Multiple ADC channels monitor PV voltage, current, and grid voltage simultaneously with hardware-trigger sync to MTU2 PWM.
Recomendado
Precision Mechatronics and Medical Equipment
The R5F72167FPU drives precision mechatronics such as dialysis pumps, infusion systems, and laboratory automation, where its hardware FPU delivers floating-point accuracy for closed-loop flow-control calculations and Kalman-filter-based sensor fusion. The deterministic interrupt response meets IEC 60601 medical electrical equipment safety expectations in supervisory firmware layers, while 1 MB flash accommodates safety stacks and FDA-510(k) audit logging. Industrial-temperature LQFP packaging supports sterilisation environments common in clinical lab hardware.

Notas de diseño
Route the high-speed oscillator traces (EXTAL/XTAL) with short, symmetric paths and guard them with a ground ring to keep the 200 MHz core phase-noise-free. Decouple every VCC/VSS pair with 100 nF X7R ceramic plus a 10 uF tantalum bulk cap, placed within 5 mm of the pin. The 176-pin LQFP footprint requires via-in-pad or stitched via fan-outs under the die paddle to maintain thermal impedance and signal return paths.
Power-supply sequencing is critical for SH-2A devices - bring up the core VCC (3.3 V or 5 V depending on variant) before the analog VCC rail to avoid latch-up. Use a separate LDO for the PLL supply if the on-chip regulator cannot hold tolerance across the industrial temperature range. A 4.7 uF ceramic on the PLL_AVCC pin per Renesas hardware manual recommendations removes jitter-induced baud-rate drift on SCI channels.
Do not confuse the R5F72167FPU with the lower-frequency R5F72115 family - the 200 MHz vs 100 MHz core speed grade requires matching flash-erase wait states and voltage scaling. The MTU2 timer interrupt vector table must be enabled in the INTC priority register before PWM output will start; missing this step is a common cause of no-PWM-output debug sessions. Always verify the JTAG pins are not assigned as GPIO in the pin-function-select register at reset.
