FAQ

What is the core architecture of the HD6417750F167?

The HD6417750F167 implements the SH-4 32-bit RISC superscalar CPU core with a five-stage pipeline, dual-issue execution capability, and an integrated IEEE 754-compliant floating-point unit. This architecture delivers over 200 MIPS at its rated 167 MHz frequency and forms the foundation of the SH7750S Group's performance profile. The HD6417750F167 uses this core to enable real-time multimedia processing in resource-constrained embedded systems.

Does the HD6417750F167 include an MMU, and what does it support?

Yes, the HD6417750F167 integrates a full Memory Management Unit (MMU) with unified TLB support for virtual-to-physical address translation. It enables page-based memory protection, context switching, and OS-level features required by Linux, VxWorks, or other protected-mode operating systems. The HD6417750F167's MMU is essential for applications needing multitasking, memory isolation, or large virtual address spaces beyond physical RAM limits.

What package type and pin count does the HD6417750F167 use?

The HD6417750F167 is packaged in a 208-pin plastic quad flat pack (QFP) with 0.5 mm lead pitch and 28 mm × 28 mm body size. This package is compatible with standard surface-mount assembly processes and provides sufficient I/O density for memory buses, peripherals, and debug interfaces. The HD6417750F167 shares this footprint with other SH7750S variants like HD6417750SF200 and HD6417750SVF133, enabling drop-in frequency scaling.

What are the supported external memory interfaces for the HD6417750F167?

The HD6417750F167 supports ROM, SRAM, DRAM, synchronous DRAM (SDRAM), and PCMCIA via its programmable Bus State Controller (BSC). It handles 64-bit SDRAM with four-bank configuration and supports 32-bit data bus widths. The HD6417750F167's BSC eliminates external wait-state logic by allowing software-configurable timing parameters for each chip select, simplifying memory subsystem design across diverse storage technologies.

Is the HD6417750F167 suitable for automotive applications?

The HD6417750F167 is specified for commercial and industrial temperature ranges (–20 °C to +75 °C) and classified by Renesas as a "Standard" quality grade product, intended for applications such as office equipment, communications gear, and industrial robots - not transportation or safety-critical automotive systems. While used historically in pre-2010 infotainment units, the HD6417750F167 does not meet AEC-Q100 or extended temperature qualifications required for modern automotive deployment.
