FAQ

What is the maximum operating frequency of the HD6417751RBA240HVU0?

The HD6417751RBA240HVU0 operates at a maximum frequency of 240 MHz. This speed is achieved using an internal PLL driven by an external 24–48 MHz crystal or oscillator connected to the CLKIN pin. The device maintains this frequency across its full industrial temperature range of –40°C to +85°C, as confirmed in Section 23.3 AC Characteristics of the Hardware Manual Rev. 4.01.

Does the HD6417751RBA240HVU0 include a memory management unit (MMU)?

Yes, the HD6417751RBA240HVU0 integrates a full-featured MMU supporting virtual memory translation, TLB management, and ASID-based context switching. This enables robust operation of Linux, VxWorks, and other protected-mode operating systems. The MMU is documented in Section 3 of the Hardware Manual and includes unified and instruction TLBs, page table walking, and exception handling for protection violations and TLB misses.

What package type and pin count does the HD6417751RBA240HVU0 use?

The HD6417751RBA240HVU0 uses a 256-pin plastic quad flat pack (QFP) package with 0.5 mm lead pitch and 28 mm × 28 mm body size. This is explicitly listed in Table H.1 (Product Lineup) and Figure B.3 (Package Dimensions) of the Hardware Manual Rev. 4.01. The "BA" in the part number denotes QFP, distinguishing it from "BP" (BGA) and "BG" (292-pin BGA) variants.

Is the HD6417751RBA240HVU0 qualified for industrial temperature operation?

Yes, the HD6417751RBA240HVU0 is rated for operation from –40°C to +85°C. This wide temperature range is specified as the standard qualification for this variant, as noted in Appendix H (Product Lineup) and reinforced in multiple AC/DC characteristic tables (e.g., Tables 23.2, 23.4, 23.9) where "Ta = –40 to 85°C for the HD6417751RBA240HV" is explicitly called out.

Does the HD6417751RBA240HVU0 support PCI bus connectivity?

Yes, the HD6417751RBA240HVU0 includes a fully integrated PCI controller compliant with PCI Specification Revision 2.2. It supports both master and slave modes, configurable BARs, DMA, and interrupt mapping. PCI signal timing, configuration registers (e.g., PCICONF0), and handling guidelines for unused PCI pins (Table D.4) are detailed in Sections 22 and D of the Hardware Manual Rev. 4.01.
