FAQ

What is the CPU architecture and instruction set compatibility of the HD6417751RBP200?

The HD6417751RBP200 implements the SH-4 32-bit RISC architecture with superscalar five-stage pipeline and dual-issue capability. It executes the full SH-4 instruction set defined in the SH-4 Programming Manual (ADE-602-156), maintaining binary compatibility with other SH-4 family members such as SH7750 and SH7751. The HD6417751RBP200 does not support SH-2 or SH-3 code natively.

Does the HD6417751RBP200 include an integrated memory management unit (MMU)?

Yes, the HD6417751RBP200 includes a full-featured MMU with 64-entry unified TLB, virtual-to-physical address translation, address space identifier (ASID) support, and page-level protection. This MMU enables HD6417751RBP200 to run full-featured operating systems such as Linux, VxWorks, or QNX that require hardware-enforced memory isolation and process protection.

What types of external memory does the HD6417751RBP200 support directly?

The HD6417751RBP200 supports ROM, SRAM, DRAM, synchronous DRAM (SDRAM), and PCMCIA memory devices via its integrated bus state controller (BSC). Its SDRAM interface supports 16-bit data width, 13-bit addressing, and standard command sequences for initialization, refresh, and burst access - enabling up to 512 MB of SDRAM with appropriate bank configuration.

Is the HD6417751RBP200 pin-compatible with other SH7751R variants?

Yes, the HD6417751RBP200 uses the same 256-pin PBGA package and identical pinout as other SH7751R variants documented in Section 1.4.2 of the SH7751 Series Hardware Manual (ADE-602-201B Rev. 3.0). This includes consistent signal naming, power/ground distribution, and functional pin mapping - allowing direct substitution within the same footprint.

What power management modes are supported by the HD6417751RBP200?

The HD6417751RBP200 supports six hardware power-down modes: Sleep, Deep Sleep, Pin Sleep, Standby, Module Standby, and Hardware Standby. In Deep Sleep mode, core logic and most peripherals are gated while retaining RAM content and register state, achieving sub-100 µA standby current. Wake-up sources include external interrupts, RTC alarm, and PCI activity.
