For engineers reviewing the R5F61622D50FPV datasheet, R5F61622D50FPV pinout, R5F61622D50FPV application, or R5F61622D50FPV equivalent, key selection criteria include its 100-pin LQFP package, 3.3 V single-supply operation, 16-channel ADC with 10-bit resolution, and support for H8SX architecture-compatible toolchains and debug interfaces.

Technical Context

The R5F61622D50FPV implements the H8SX CPU core with three operating modes-Normal, Middle, and Advanced-enabling configurable instruction set access and privilege levels. It integrates a Clock Pulse Generator (CPG) supporting internal PLL multiplication and multiple clock sources, including external crystal (1–20 MHz) and on-chip oscillator.

Peripheral subsystems include a Data Transfer Controller (DTC) for autonomous memory-to-peripheral transfers, an Interrupt Controller (INTC) with 128 interrupt sources and priority encoding, and a Bus Controller (BSC) managing external memory bus timing and wait-state insertion for SRAM, EPROM, or NAND flash expansion.

FAQ

What is the maximum operating frequency of the R5F61622D50FPV?

The R5F61622D50FPV supports a maximum CPU clock frequency of 50 MHz, achieved via internal PLL multiplication of an external crystal (1–20 MHz) or CMOS clock source. This frequency is fully supported across the full industrial temperature range (−40°C to +85°C) and enables sub-microsecond interrupt response times essential for real-time motor control loops. The R5F61622D50FPV's CPG module provides configurable pre-divider and multiplier settings to meet precise system timing requirements.

Does the R5F61622D50FPV support in-circuit debugging?

Yes, the R5F61622D50FPV includes the User Break Controller (UBC) module, which provides non-intrusive hardware breakpoints, real-time trace, and memory access monitoring through dedicated debug pins. This capability allows full source-level debugging using Renesas E1/E20 emulators and compatible IDEs without requiring additional external probes. The R5F61622D50FPV's UBC implementation complies with H8SX architecture specifications and supports both flash and RAM execution debugging.

What package type and pin count does the R5F61622D50FPV use?

The R5F61622D50FPV is supplied in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with an exposed thermal pad. This package supports standard reflow soldering profiles and provides full access to all I/O, peripheral, and power pins as defined in the H8SX/1622 Group Hardware Manual Rev. 2.00. The R5F61622D50FPV's pin mapping is shared across the H8SX/1622 family, enabling PCB reuse for variants like R5F61620D50FPV and R5F61624D50FPV.

Can the R5F61622D50FPV operate from a single 3.3 V supply?

Yes, the R5F61622D50FPV operates from a single 3.3 V ±5% supply across its full industrial temperature range. Internal voltage regulators generate core (1.8 V) and I/O (3.3 V) domains, eliminating the need for external DC-DC converters. All I/O pins are 5 V tolerant only in specific configurations documented in the electrical characteristics table-standard operation assumes 3.3 V logic levels. The R5F61622D50FPV's power architecture is optimized for low-noise industrial environments with tight supply ripple budgets.

Is the R5F61622D50FPV qualified for automotive applications?

No, the R5F61622D50FPV is classified as a "Standard" quality grade device per Renesas documentation and is intended for industrial applications such as motor drives, PLCs, and factory automation-not automotive or safety-critical systems. It does not meet AEC-Q100 requirements, lacks automotive temperature range (−40°C to +125°C), and has no ISO 26262 functional safety certification. For automotive use, Renesas recommends RH850 or RL78/F1x families instead of the R5F61622D50FPV.
