FAQ

What is the maximum operating frequency of the R5F61652D50FPV?

The R5F61652D50FPV operates at a maximum CPU clock frequency of 40 MHz, achieved via its integrated Clock Pulse Generator (CPG) with PLL multiplier. This frequency is validated across the full −40°C to +85°C temperature range and 3.3 V ±0.3 V supply voltage, enabling sub-25 ns instruction cycle timing for hard real-time tasks. The R5F61652D50FPV's timing specifications are fully documented in the H8SX/1655 Group Hardware Manual Rev. 2.00.

Does the R5F61652D50FPV support in-circuit debugging?

Yes, the R5F61652D50FPV includes a standard IEEE 1149.1 JTAG interface for full-speed in-circuit debugging, flash programming, and boundary-scan testing. This interface supports real-time register inspection, breakpoint setting, and memory read/write operations without halting peripheral operation. The R5F61652D50FPV's JTAG implementation complies with Renesas' E10A-USB and E20 emulator protocols.

What memory protection mechanisms does the R5F61652D50FPV provide?

The R5F61652D50FPV incorporates a configurable Memory Protection Unit (MPU) that enforces region-based access control for on-chip Flash, RAM, and peripheral registers. It supports up to 8 protected memory regions with independent read/write/execute permissions, preventing accidental or malicious corruption of critical firmware sections. This MPU functionality is integral to the R5F61652D50FPV's architecture and is activated via dedicated system control registers.

Can the R5F61652D50FPV generate multi-phase PWM waveforms?

Yes, the R5F61652D50FPV combines its Programmable Pulse Generator (PPG) and 16-bit Timer Pulse Unit (TPU) to generate synchronized multi-phase PWM waveforms. The PPG provides 4 independent channels with phase-shift and dead-time control, while the TPU adds 8 additional channels with complementary output pairs. This dual-peripheral capability allows the R5F61652D50FPV to drive 3-phase inverters or stepper motor drivers without external logic.

Is the R5F61652D50FPV RoHS-compliant?

Yes, the R5F61652D50FPV is RoHS-compliant and lead-free, as indicated by the "V" suffix in its part number. It meets EU Directive 2011/65/EU and China RoHS II requirements, with homogeneous material analysis confirming Pb content below 0.1 wt%. This compliance is verified in Renesas' official product change notices and material declarations for the H8SX/1652 Group.
