It operates at 240 MHz with 1.5 V internal supply voltage, integrates an MMU, 16 KB instruction cache, 16 KB operand cache, and supports 64-bit SDRAM interfaces. It targets high-performance embedded multimedia systems requiring real-time OS support and memory protection.

For engineers reviewing the HD6417750RX240V datasheet, HD6417750RX240V pinout, HD6417750RX240V application, or HD6417750RX240V equivalent, key selection criteria include its 240 MHz SH-4 execution speed, 256-pin BGA package (0.8 mm pitch), -20 to +75°C operating temperature range, and integrated peripheral set including SCIF, RTC, UBC, and BSC for system-on-chip design.

Technical Context

The HD6417750RX240V implements the SH-4 superscalar RISC architecture with dual-issue pipeline, supporting both integer and floating-point operations. It features a unified 32-entry TLB, hardware-managed MMU for virtual memory translation, and separate 16 KB instruction and operand caches with write-back policy.

Its bus state controller (BSC) supports asynchronous and synchronous DRAM, PCMCIA, and 64-bit SDRAM with 4-bank configuration. The device includes two serial interfaces (SCI/SCIF), real-time clock, user break controller, and smart card interface - all mapped into a single 32-bit address space with configurable wait states and burst access modes.

FAQ

What is the maximum operating frequency of the HD6417750RX240V?

The HD6417750RX240V operates at a maximum frequency of 240 MHz. This speed is achieved with a 1.5 V internal supply and requires stable 3.0–3.6 V I/O voltage. The device uses PLL circuitry to derive internal clocks from an external crystal or oscillator source, and timing compliance must be verified against Table 22.15 and 22.23 in the Hardware Manual Rev.7.02.

Does the HD6417750RX240V include an integrated memory management unit (MMU)?

Yes, the HD6417750RX240V includes a full-featured MMU supporting virtual memory management. It implements a 32-entry unified TLB and supports both single and multiple virtual memory modes. The MMU enables protected-mode operating systems such as Linux and VxWorks to run securely on the HD6417750RX240V, with hardware-enforced page-level access control and ASID-based context switching.

What package type is used for the HD6417750RX240V?

The HD6417750RX240V uses a 256-pin fine-pitch BGA package with 0.8 mm ball pitch and 17 mm × 17 mm body size. This package is distinct from the 292-pin BGA used in HD6417750RBG240 and the enhanced 256-pin variant in HD6417750RBA240HV. Layout guidelines, solder paste stencil recommendations, and thermal pad requirements are specified in Appendix B of the Hardware Manual.

Which serial interfaces are integrated into the HD6417750RX240V?

The HD6417750RX240V integrates two serial communication interfaces: one SCI (Serial Communication Interface) and one SCIF (Serial Communication Interface with FIFO). Both support asynchronous communication, programmable baud rates, and full-duplex operation. SCIF adds 16-byte transmit/receive FIFOs and enhanced error detection, making it suitable for high-throughput data transfer in applications like media streaming or industrial protocol bridging.

Is the HD6417750RX240V suitable for automotive applications?

The HD6417750RX240V is rated for –20 to +75°C operation and classified as a Standard-grade Renesas product, intended for commercial and industrial equipment-not automotive safety-critical systems. For automotive use, Renesas specifies the HD6417750RBA240HV (–40 to +85°C) as the qualified alternative; the HD6417750RX240V lacks AEC-Q100 qualification and does not meet transportation-grade reliability requirements.
