FAQ

What is the maximum operating frequency of the HD6417705BP100V?

The HD6417705BP100V operates at a maximum CPU clock frequency of 100 MHz, achieved via its internal PLL1 circuit locked to an external crystal or clock source. This frequency is specified under recommended operating conditions (VCC = 1.4–1.6 V, Ta = –20 to +75°C) and enables deterministic real-time execution of SH-3E instructions. The HD6417705BP100V's peripheral bus runs at lower frequencies derived from PLL2, ensuring balanced system performance.

Does the HD6417705BP100V include an integrated USB transceiver?

Yes, the HD6417705BP100V integrates a full-speed USB 2.0 device transceiver compliant with the USB specification. It supports 12 Mbps data rates and handles all physical layer signaling, including differential line termination and slew rate control. No external PHY is required - only standard 27 Ω series resistors and a 1.5 kΩ pull-up resistor on the USB_DP line are needed for USB device enumeration. This capability is confirmed in the SH7705 Hardware Manual Rev. 2.00, Section 1.1 and Figure 6.1.

What package type and pin count does the HD6417705BP100V use?

The HD6417705BP100V uses a 208-pin Low Profile Quad Flat Package (LQFP) with 0.5 mm lead pitch and 28 mm × 28 mm body dimensions. This package is explicitly documented in the SH7705 Hardware Manual Rev. 2.00, Section 1.3 (Pin Assignment) and Table 1.2 (Pin Functions), where pin numbers 1 through 208 are defined. The "BP100V" suffix denotes this specific LQFP variant.

Can the HD6417705BP100V execute Linux or other full-featured OSes?

Yes, the HD6417705BP100V supports full-featured operating systems including Linux and μITRON due to its integrated Memory Management Unit (MMU) with 64-entry Translation Lookaside Buffer (TLB) and support for virtual memory addressing. The SH-3E core implements the necessary privilege levels, exception vectors, and page table management instructions. Real-world deployments include Linux-based industrial gateways where the HD6417705BP100V manages network stacks, file systems, and application services.

What debug interface does the HD6417705BP100V support?

The HD6417705BP100V supports the User Debugging Interface (UDI) compliant with IEEE 1149.1 (JTAG), using pins TDI, TCK, TMS, TRST, and TDO. It also includes boundary-scan capability via a 385-bit Shift Data Boundary Scan Register (SDBSR). This allows in-circuit debugging, flash programming, and manufacturing test without requiring additional debug probes beyond standard JTAG adapters. The UDI implementation is detailed in Sections 23.3 and 23.5 of the SH7705 Hardware Manual Rev. 2.00.
