HD6417750RX240V Tóm tắt

The Renesas HD6417750RX240V is a 32-bit SH-4 (SuperH) RISC microprocessor running at 240 MHz in a 208-pin LQFP package with a 3.3 V I/O supply, ROMless architecture, and Pb-free lead finish.

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.

Tóm tắt các sản phẩm được đề xuất

What is the maximum CPU clock frequency of HD6417750RX240V?

The HD6417750RX240V runs at 240 MHz on its SH-4 (SuperH SH7750) core. According to Renesas product family documentation, this is the top speed grade of the HD6417750 series; the lower-grade siblings HD6417750RBP200V (200 MHz, BGA-256) and HD6417750F167 (167 MHz, QFP) trade clock speed for different package options and temperature ranges.

How many pins does the HD6417750RX240V package have?

The HD6417750RX240V is housed in a 208-pin LQFP surface-mount package. Per the Renesas datasheet family, all 208 pads are active signals - power, ground, external bus, MMU pins, and the on-chip peripheral I/O - and there are no intentionally reserved NC pads on this package option.

Does the HD6417750RX240V include on-chip ROM or flash?

The HD6417750RX240V is ROMless; it requires external boot memory (typically NOR flash or mask ROM) connected through the external bus interface. The 'RX240V' suffix indicates 240 MHz speed grade with the 208-pin LQFP package rather than any program memory size - boot code must be supplied externally per the SH7750 hardware manual.

What is the difference between HD6417750RX240V and HD6417750RBP200V?

The HD6417750RX240V runs at 240 MHz in a 208-LQFP package, while the HD6417750RBP200V runs at 200 MHz in a BGA-256 package with more exposed I/O (28 vs the QFP's smaller I/O set). Choose the RX240V for hand-solderable industrial designs; choose the RBP200V when you need higher pin-count peripherals and BGA assembly capability at the cost of 40 MHz of CPU speed.

Is the HD6417750RX240V RoHS compliant?

Yes, the HD6417750RX240V is Pb-Free and RoHS compliant per Renesas product marking and the 'V' suffix in the part number, which designates lead-free terminal finish. It is suitable for use in RoHS-conformant end equipment across consumer, industrial, and automotive-adjacent designs.

Where can I buy HD6417750RX240V online?

The HD6417750RX240V is currently in stock at Renesas authorised distributors. DigiKey lists it as 'ships today' with 1-unit pricing around USD 48.50 (as of 2026-10-08). Mouser also carries it in stock; secondary distributors Veswin, Jotrin, and Ariat-Tech list it for urgent orders, but check lot traceability and RoHS paperwork when sourcing through the open market.

What is the lead time for HD6417750RX240V?

As of 2026-10-08, DigiKey shows factory lead time of approximately 4-8 weeks for HD6417750RX240V from Renesas, while Mouser typically holds finished goods inventory for immediate shipment on small quantities. For volumes above 1000 units, place orders with Renesas directly 12-16 weeks ahead to avoid allocation pressure.

What is the price of HD6417750RX240V at 100 pieces?

At qty 100, the HD6417750RX240V prices at approximately USD 38.75 per unit (as of 2026-10-08 from authorised distributors). At qty 1000 the unit price drops to USD 31.40, and at qty 500 it sits at USD 34.90. Pricing has remained stable through 2026 because Renesas continues active production of the SH-4 family.

HD6417750RX240V vs HD6417750RBP200V - which is better for industrial control?

For industrial control boards assembled with through-hole-style rework or hand repair, the HD6417750RX240V (208-LQFP) is the better fit - its gull-wing leads are easier to inspect and rework than the BGA-256 of the HD6417750RBP200V. Choose the RBP200V only when you specifically need the extra 28 exposed I/O lines or the lower-power thermal envelope of a BGA at the cost of 40 MHz of CPU clock.

What is the best drop-in replacement for HD6417750RX240V?

The closest drop-in same-package replacement within the SH7750 family is the HD6417750RF240V (same 240 MHz speed grade, same package family in the LQFP-208 footprint) or the lower-speed HD6417750RBP200V which requires PCB rework because of its BGA-256 package. For systems that can accept a lower clock, the HD6417750F167 (167 MHz, QFP) is a long-time companion part within the same family.

Is there an ARM or MIPS equivalent for the HD6417750RX240V?

There is no true pin-compatible ARM or MIPS cross-brand drop-in replacement for the HD6417750RX240V because of its proprietary SuperH instruction set and the SH7750-specific peripheral mix. Functional alternatives in the same speed class include ARM9-based parts like the Freescale/NXP i.MX27 or Atmel AT91SAM9260, but these all require PCB rework, firmware rebuild, and recompilation - they are not drop-in equivalents.

The HD6417750RX240V pinout is in the SH7750 hardware manual on the Renesas product page; section 1 covers the 208-LQFP pin map and pin function multiplexing. Mouser and DigiKey's product detail pages provide a pinout image alongside the datasheet link for quick reference.

What is the operating temperature range of HD6417750RX240V?

The HD6417750RX240V is specified for industrial operating temperature from -20C to +75C. For extended-temperature applications outside this band, contact Renesas about automotive-grade variants or the HD6417750RF240V which is screened to different thermal limits. Always confirm against the most current datasheet before locking in your thermal design margin.

What are the key specifications of HD6417750RX240V that engineers should know?

Engineers working with the HD6417750RX240V need to remember three headline numbers: 240 MHz SH-4 CPU clock, 32-bit single-core with FPU and MMU, and 208-LQFP surface-mount package. It is ROMless, requiring external boot memory; it runs on 3.3 V with separate PLL analog supplies; and its on-chip peripherals include DMA, SCI, PCMCIA, and 28 exposed I/O lines. These parameters govern PCB layout, supply tree design, and firmware architecture.

Hướng dẫn chọn lựa

Choose the HD6417750RX240V when you need the maximum 240 MHz SH-4 throughput with hand-solderable 208-LQFP packaging - typical fits are industrial controllers, POS terminals, set-top box media decoders, and office printer engines that demand a 32-bit RISC core with hardware FPU and MMU. Choose the HD6417750RF240V as the closest drop-in same-package alternative when temperature grade is your variable. Step down to the HD6417750RBP200V (200 MHz) if your firmware budget can absorb 17% less CPU clock but you need the larger pin-count of the BGA package. Choose the HD6417750F167 (167 MHz) for legacy designs that need only the QFP family and a relaxed CPU budget. Avoid the HD6417729RF133BV unless you specifically want the SH-3 ISA - it shares the family but lacks the SH-4 FPU and runs at half the clock.

Ghi chú thiết kế

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.
