It supports 64-bit SDRAM, PCMCIA, and synchronous DRAM interfaces, and targets high-performance multimedia embedded systems requiring real-time processing and memory management.

For engineers reviewing the HD6417750RX240DV datasheet, HD6417750RX240DV pinout, HD6417750RX240DV application, or HD6417750RX240DV equivalent, key selection criteria include its 240 MHz SH-4 core performance, 1.5 V core voltage, -40°C to +85°C industrial temperature grade, BGA package compatibility, and integrated peripheral set including dual SCIF, RTC, UBC, and BSC.

Technical Context

The HD6417750RX240DV implements the full SH-4 architecture with five-stage superscalar pipeline, dynamic branch prediction, and IEEE 754-compliant FPU. It integrates a unified TLB (UTLB) and separate instruction TLB (ITLB), supporting both single and multiple virtual memory modes with ASID-based context switching.

Its bus state controller (BSC) provides configurable timing for ROM, SRAM, DRAM, SDRAM (including 4-bank 64-bit), and PCMCIA, while the memory management unit (MMU) enables protected multitasking OS environments via page-level protection and address translation.

FAQ

What is the core architecture and maximum operating frequency of the HD6417750RX240DV?

The HD6417750RX240DV implements the SuperH™ SH-4 32-bit RISC CPU core and operates at a maximum frequency of 240 MHz. Its five-stage superscalar pipeline, dynamic branch prediction, and integrated FPU deliver high integer and floating-point throughput. This frequency is achievable under specified conditions: VDD = 1.5 V, VDDQ = 3.0–3.6 V, and ambient temperature within –40°C to +85°C. The HD6417750RX240DV's clock tree and PLL configuration are detailed in Section 22.3 of the Hardware Manual Rev. 7.02.

Does the HD6417750RX240DV include an integrated memory management unit (MMU)?

Yes, the HD6417750RX240DV includes a full-featured MMU supporting virtual memory, page-level protection, and ASID-based context switching. It features both a unified TLB (UTLB) and a dedicated instruction TLB (ITLB), enabling secure multitasking OS environments such as Linux or VxWorks. The MMU is fully programmable via system registers and supports both single and multiple virtual memory modes. This capability is confirmed in Sections 3 and 2.2.4 of the HD6417750RX240DV Hardware Manual.

What package type and pin count does the HD6417750RX240DV use?

The HD6417750RX240DV uses a 256-pin fine-pitch ball grid array (BGA) package with 1.0 mm ball pitch and a 17 mm × 17 mm body size. This package is distinct from the 292-pin BGA used by HD6417750RBG240 and the enhanced 256-pin variant HD6417750RBA240HV. Pin functions-including VDD/VSS core power, VDDQ/VSSQ I/O power, CLKIN, RESET#, ADDR/DATA buses, and control signals-are fully documented in Section 1.4.1 of the Hardware Manual Rev. 7.02.

What is the operating temperature range and quality grade of the HD6417750RX240DV?

The HD6417750RX240DV is rated for operation from –40°C to +85°C and belongs to Renesas Electronics' "High Quality" grade. As defined in the manual's Notice section, this grade is intended for transportation equipment, traffic control, anti-disaster, and safety-critical systems. The device meets industrial environmental requirements and is not authorized for life-support or nuclear safety applications. Full thermal and reliability specifications are provided in Table 22.1 (Absolute Maximum Ratings) and Section 22.2 (DC Characteristics).

Which peripheral interfaces are integrated into the HD6417750RX240DV?

The HD6417750RX240DV integrates a comprehensive set of peripherals: two serial communication interfaces (SCIF), real-time clock (RTC) with battery backup, user break controller (UBC), bus state controller (BSC), memory management unit (MMU), instruction and data caches (16 KB each), and a smart card interface compliant with ISO/IEC 7816-3. These are detailed in the Preface and Section 1.1 (Features) of the Hardware Manual Rev. 7.02. No Ethernet MAC, USB, or CAN controller is included - external PHY or bridge ICs are required for those functions.
