FAQ

What is the maximum operating frequency of the R5F72167BDBG#U1?

The R5F72167BDBG#U1 operates at a maximum CPU frequency of 120 MHz using its on-chip PLL with external crystal input. This frequency is achievable across the full industrial temperature range (−40°C to +85°C) when supplied with 3.3 V ±10% and proper decoupling. The R5F72167BDBG#U1's CPG supports multiple clock sources and fractional dividers to maintain timing integrity under dynamic load conditions.

Does the R5F72167BDBG#U1 include an integrated USB physical layer?

Yes, the R5F72167BDBG#U1 integrates a full-speed USB 2.0 transceiver with internal PHY, eliminating the need for external USB interface ICs. It supports both host and device modes, automatic speed negotiation, suspend/resume detection, and battery charging detection (BCD). This capability is confirmed in the SH7216 Group Hardware User's Manual Rev. 4.00, Section 4.8.

How many CAN controllers are implemented in the R5F72167BDBG#U1?

The R5F72167BDBG#U1 features two independent CAN 2.0B controllers, each with dedicated message RAM, acceptance filtering, and error counters. These controllers operate concurrently without shared resources, enabling simultaneous communication on separate CAN networks - such as chassis and body domains in automotive applications. This dual-CAN capability is documented in the SH7216 Group peripheral specification tables.

What is the ADC resolution and channel count supported by the R5F72167BDBG#U1?

The R5F72167BDBG#U1 integrates a 12-bit successive approximation register (SAR) ADC with 24 input channels and a minimum conversion time of 1.25 μs. It supports hardware triggering from multiple sources including MTU3 timers and external pins, and includes built-in averaging and offset calibration. This ADC configuration is specified in the "Analog Functions" section of the SH7216 Group Hardware User's Manual.

Is the R5F72167BDBG#U1 pin-compatible with other members of the SH7216 Series?

Yes, the R5F72167BDBG#U1 is pin-compatible with other 144-pin LQFP variants in the SH7216 Series, including R5F72165BDBG#U1 and R5F72168BDBG#U1. All share identical pin assignments, power sequencing requirements, and peripheral signal mapping. This allows direct substitution within the same PCB layout when memory or feature requirements change - confirmed in the "Pin Assignment" section (Section 1.3) of the SH7216 Group Hardware User's Manual.
