FAQ

What is the maximum operating frequency of the HD6417145F50V?

The HD6417145F50V operates at a maximum clock frequency of 50 MHz, achieved via its on-chip PLL that multiplies an external 4–8 MHz crystal input. This frequency defines the core instruction execution rate (50 MIPS) and sets timing constraints for all synchronous peripherals including SCI, CAN, and external bus cycles. The HD6417145F50V must be powered with 3.3 V ±0.3 V to sustain stable 50 MHz operation across the full −40°C to +85°C temperature range.

Does the HD6417145F50V include on-chip flash memory?

No, the HD6417145F50V is the ROM-less variant of the SH7145 Group and contains no embedded non-volatile program memory. It relies on external memory (e.g., parallel NOR flash or SRAM) connected via its 16-bit external bus interface. In contrast, the HD64F7145F50V variant integrates 256 KB of on-chip flash. The HD6417145F50V is intended for applications where firmware resides externally or is loaded dynamically at boot.

Which communication interfaces are integrated into the HD6417145F50V?

HD6417145F50V integrates three asynchronous serial interfaces (SCI), one I²C bus interface, and one CAN v2.0B controller - all implemented in hardware with dedicated registers and DMA support. These interfaces operate independently and can run concurrently; the CAN module supports full 11-bit and 29-bit identifier filtering, while the SCIs support LIN protocol emulation via software. No external transceivers are required for basic functionality, though physical layer drivers must be added for bus compliance.

What debug capabilities does the HD6417145F50V provide?

The HD6417145F50V supports background debug mode (BDM) compliant with IEC 60356, accessible via dedicated MD and CLKOUT pins. This enables non-intrusive debugging including hardware breakpoints, real-time register and memory inspection, and single-stepping - all without halting peripheral operation. Debug requires Renesas E8/E8a emulator hardware and HEW (High-performance Embedded Workshop) IDE. The HD6417145F50V does not include JTAG; BDM is its sole standardized debug interface.

Is the HD6417145F50V pin-compatible with other SH7145 Group members?

Yes, the HD6417145F50V shares identical 144-pin LQFP packaging and pin assignment with all SH7145 Group variants including HD64F7145F50V and HD6437145F50V. Pin functions (e.g., P0_0 through P13_7, CLKIN, RESET, VCC, VSS) are fully consistent across the group. However, differences in boot configuration (MD pin states) and internal memory presence require corresponding changes to hardware strapping and startup code - making them functionally compatible but not drop-in replacements without firmware adaptation.
