HD6417750SX167V Présentation
An SH-4 SuperH microprocessor belongs to the superscalar RISC CPU family originally developed by Hitachi and now maintained by Renesas Electronics Corporation. The SH-4 instruction set extends the earlier SH-1/SH-2 ISA with 16-bit fixed-length instructions and adds a 128-bit media extension (SIMD-style) for multimedia and DSP-style workloads. Within the broader semiconductor taxonomy, the SH7750 sits in the hierarchy: SH-4 core -> SuperH family -> 32-bit RISC microcontroller -> embedded processor -> semiconductor IC. The ROMless designation means the chip executes code from external NOR flash, SRAM, or SDRAM, providing maximum firmware flexibility for long-lifecycle industrial designs.
Key differentiating features include 167 MHz sustained core frequency, hardware IEEE 754 single-precision floating-point unit, integrated memory management unit (MMU) supporting virtual memory, separate 32 KB instruction and 32 KB data caches with write-back policy, and a peripheral set encompassing DMAC, timer, SCI, and a powerful 32-bit external bus. The on-chip FPU executes single-precision floating-point in one cycle for SIMD instructions and supports vector arithmetic. With five-stage pipeline architecture and dual-issue superscalar dispatch, the SH-4 delivers up to 360 MIPS / 1.4 GFLOPS peak throughput, enabling real-time video, audio, and control processing without external co-processors.
Typical applications include industrial machine controllers, networked printers, multifunction office imaging systems, set-top box controllers, point-of-sale terminals, and embedded HMI panels. The wide 32-bit external bus and SDRAM controller support high-bandwidth data movement required for image scanning and printing pipelines. The integrated MMU enables full Linux and Windows CE operating system support, opening the device to open-software stacks used in commercial embedded products.
When designing with this part, allocate sufficient PCB area for the 208-pin LQFP and ensure the external memory bus traces are length-matched for SDRAM operation above 100 MHz. The device requires a 3.3 V I/O supply and a separate core voltage rail; decoupling must follow Renesas reference layout for stable PLL lock.

Notes de conception
The HD6417750SX167V requires a stable 3.3 V I/O supply and a separate lower-voltage core rail driven by the on-chip voltage regulator. Decoupling must follow the Renesas reference design with bulk capacitors near each VCC/GND pair and 0.1 uF ceramics on every supply pin. Estimated: at 167 MHz full operation, total power consumption is approximately 1.5 W - use at least 4-layer PCB with a dedicated ground plane to keep impedance low.
Allocate a 208-pin LQFP land pattern with 0.5 mm pitch per the JEDEC MS-026 package outline. Length-match the external SDRAM address/command traces within +/-50 mil and route data signals with impedance control (typically 50 ohm single-ended). The exposed pad on certain variants should be soldered to a thermal copper pour connected to digital ground for heat spreading.
Do not boot the device with the BSC configured for the wrong external memory type - incorrect SDRAM timing parameters cause intermittent boot failures. The PLL requires stable clock reference with appropriate load capacitance; mismatch causes PLL unlock. Designers should verify boot mode pins are pulled correctly at reset for the chosen memory map configuration.
