R5F72167FAUSH2A Descripción general
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.

Notas de diseño
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.
