HD6417750RX240V - SH-4 240MHz 32-Bit MPU, 208-QFP | Renesas
MPN: HD6417750RX240V ✓ فعالHD6417750RX240V نمای کلی
An MPU (Microprocessor Unit) in this category is a 32-bit superscalar RISC core that executes the SuperH instruction set and connects to external SDRAM, SRAM, and ROM through an external bus interface. The HD6417750RX240V belongs to the SH7750 family and sits at the top of the embedded processing hierarchy between microcontroller units (MCU) and full application processors, with explicit multimedia (MMU, cache, FPU) extensions. SH-4 cores have been used in set-top boxes, printers, industrial control, and automotive infotainment where deterministic 32-bit performance exceeds what 8/16-bit controllers can deliver.
Key features of the HD6417750RX240V include a 240 MHz CPU clock, an integrated FPU, separate 16 KB instruction and 8 KB data caches, an MMU with TLB, and an external bus interface supporting SDRAM, PCMCIA, and burst ROM. The 208-pin LQFP package exposes all of these signals plus serial, USB, and timer peripherals, allowing a compact PCB layout without BGA complexity.
The architecture combines a dual-issue superscalar pipeline with a Harvard-style cache structure, achieving roughly 360 MIPS / 1.4 GFLOPS sustained throughput at 240 MHz. On-chip peripherals include DMA, SCI (UART), timers, and a PCMCIA controller, which is unusual for embedded MPUs of this class. The part is fabricated in a low-power CMOS process that lets designers hold the core in software-controlled standby while keeping external bus monitoring active.
Typical applications include industrial machine controllers, point-of-sale terminals, set-top box media decoders, and OEM printer/copier controllers. The 240 MHz speed and FPU make it well suited for JPEG/MPEG-1 software codecs and for the control loops in office imaging equipment.
When designing with this part, remember that it is ROMless - boot firmware must reside in external flash or ROM. Provide a PLL loop filter network per the hardware manual and observe the 3.3 V supply tolerance (typically +/-5%) to keep the PLL locked across temperature. The LQFP package simplifies rework versus BGAs in legacy industrial designs.

کاربردهای معمول
HD6417750RX240V مناسب است برای 6 کاربردs: Industrial Machine Controllers, Point-of-Sale (POS) Terminals, Set-Top Box Media Decoders, Office Printer and Copier Controllers, Automotive Infotainment Head Units, Test and Measurement Front-Ends.
Industrial Machine Controllers
The HD6417750RX240V's 240 MHz SH-4 core with hardware FPU delivers the deterministic 32-bit throughput required for industrial machine controllers driving stepper/servo loops. Its ROMless architecture lets designers fit deterministic boot firmware in external NOR flash, while the 16 KB instruction / 8 KB data cache absorbs the tight inner loops in PID and trajectory planners. The 208-LQFP package simplifies field service and rework compared with BGA alternatives in long-life industrial equipment. PCMCIA and external bus interfaces connect to legacy I/O cards used in factory floor designs.

Point-of-Sale (POS) Terminals
POS terminals benefit from the HD6417750RX240V's 240 MHz SH-4 throughput and FPU when running encryption, display rendering, and printer-control tasks simultaneously. The integrated DMA controller offloads screen buffer transfers, and the SCI peripherals drive magnetic-stripe and smart-card readers directly without external UART chips. The 3.3 V single-supply operation simplifies the power tree in compact retail terminals where board area is at a premium. Long-term Renesas production availability keeps multi-year POS deployments supported.
پیشنهادی
Set-Top Box Media Decoders
The HD6417750RX240V's 240 MHz SH-4 with FPU and MMU handled MPEG-1, MPEG-2, and JPEG decode in early set-top box designs before dedicated DSPs took over. Its SDRAM and burst ROM bus interface supports the memory bandwidth needed for compressed video streams at standard definition. ROMless boot from external flash simplifies regional firmware variants and on-field updates. The 208-LQFP package and 3.3 V supply simplify power design in cost-sensitive consumer hardware.
پیشنهادی
Office Printer and Copier Controllers
Office printers and copiers use the HD6417750RX240V to drive the engine, scanner, and user-interface subsystems from a single 32-bit RISC core. The 240 MHz clock and FPU accelerate image processing pipelines (deskew, halftone, JPEG compression) while the on-chip DMA moves page buffers between the scanner engine and the print engine. The PCMCIA controller is ideal for option-card slots (memory, network, finisher interfaces). LQFP-208 package supports the long lifecycle typical of office equipment.
پیشنهادی
Automotive Infotainment Head Units
The HD6417750RX240V was adopted in early automotive infotainment head units for its 240 MHz multimedia performance, MMU-supported virtual memory, and 208-LQFP package that simplified under-dash PCB assembly. The SCI peripherals connect to radio tuners and CD-changer decks while the external bus interfaces to graphics LCD controllers. Designers must respect the -20C to +75C industrial temperature window and apply conformal coating for under-dash humidity. The Pb-free finish meets automotive end-of-life directives.
پیشنهادی
Test and Measurement Front-Ends
Test and measurement instruments use the HD6417750RX240V's 240 MHz performance and floating-point math to compute FFTs, RMS, and statistical aggregates on streaming ADC data. The ROMless architecture lets designers update calibration and instrument firmware through external flash without touching the silicon. The on-chip DMA pairs naturally with high-speed parallel ADC front-ends. The 208-LQFP package and 3.3 V supply simplify integration alongside precision analog chains.

یادداشت‌های طراحی
Estimated: the HD6417750RX240V draws approximately 350 mA at 3.3 V from the Vcc and AVcc rails at 240 MHz with both caches active (based on Renesas SH7750 hardware manual typical figures). Use a low-impedance 3.3 V plane with multiple 10 uF bulk plus 0.1 uF ceramic decoupling placed within 5 mm of every Vcc/Vss pair to control switching noise and to keep the PLL supply (PLLVcc, pin 208) clean - separate this analog PLL rail with an LC filter from the noisy digital 3.3 V plane per the SH7750 hardware manual.
Estimated at 240 MHz with 1.2 W typical dissipation, the 208-LQFP junction-to-ambient thermal resistance of approximately 35 C/W yields a 42 C rise above ambient - well within the -20C to +75C industrial range without active cooling. For sealed enclosures with limited airflow, however, add a 1-oz copper flood under the exposed pad region and thermal vias to the inner plane to keep Tj below 100 C at the high end of the temperature window.
Route the external address, data, and SDRAM control signals in matched-length groups with 50 ohm characteristic impedance on the outer microstrip layers. Keep the PLL loop filter network within 10 mm of pins 1 (XTAL) and 208 (PLLVcc) and surround it with a ground moat to prevent digital switching noise from corrupting the VCO. Place external SDRAM chips on the same side as the SH-4 to minimise via stubs on the high-speed byte lanes.
The HD6417750RX240V is ROMless - boot firmware must reside in external flash connected to CS0. Failing to provide a valid reset vector at boot latches the core in an undefined state. Always assert RESET for at least 100 ms after Vcc stabilises and configure the MD0-MD4 mode pins before RESET deassertion to set bus width, endianness, and clock mode.
