For engineers reviewing the D6417750RBA240HVU0 datasheet, D6417750RBA240HVU0 pinout, D6417750RBA240HVU0 application, or D6417750RBA240HVU0 equivalent, key selection criteria include its extended industrial temperature range (–40°C to +85°C), 256-pin BGA package with HV variant pinout, 240 MHz/1.5 V operation, and integrated peripheral set including SCIF, RTC, UBC, and BSC.

Technical Context

The D6417750RBA240HVU0 implements the SH-4 superscalar RISC architecture with five-stage pipeline, dual-issue capability, and IEEE 754-compliant FPU. Its memory management unit (MMU) supports virtual memory translation via unified TLB with 64 entries and ASID-based context switching.

It features dual serial interfaces (SCI and SCIF), real-time clock (RTC), user break controller (UBC), bus state controller (BSC) for DRAM/SDRAM/PCMCIA compatibility, and on-chip 4 KB RAM. The device uses separate 16 KB instruction and 16 KB operand caches with write-back policy and lockable cache lines.

FAQ

What is the maximum operating frequency of the D6417750RBA240HVU0?

The D6417750RBA240HVU0 operates at a maximum frequency of 240 MHz. This speed is achieved with a 1.5 V internal supply voltage and requires VDDQ between 3.0 V and 3.6 V. The device uses PLL2 for internal clock multiplication and meets timing specifications across its full –40°C to +85°C operating temperature range. All AC characteristics in the hardware manual (Rev. 7.02) are validated at this frequency for the D6417750RBA240HVU0 variant.

Does the D6417750RBA240HVU0 include an integrated memory management unit (MMU)?

Yes, the D6417750RBA240HVU0 includes a full-featured MMU supporting virtual memory translation via a 64-entry unified TLB and ASID-based context switching. This enables secure multitasking and POSIX-compliant OS deployment such as Linux or VxWorks. The MMU is functionally identical across the SH7750R family and documented in Section 3 of the Hardware Manual (R01UH0456EJ0702 Rev. 7.02).

What package type and pin count does the D6417750RBA240HVU0 use?

The D6417750RBA240HVU0 uses a 256-pin fine-pitch BGA package with 0.8 mm ball pitch and 17 mm × 17 mm body size, designated as the "HV" variant. Its pinout differs from standard 256-pin BGA variants (e.g., HD6417750RBP240) and is defined in Figure B.5 of Appendix B in the Hardware Manual (Rev. 7.02). Mechanical dimensions and solder mask layout must follow Renesas' HV-specific guidelines.

Is the D6417750RBA240HVU0 qualified for extended temperature operation?

Yes, the D6417750RBA240HVU0 is explicitly rated for –40°C to +85°C operation, as confirmed in Table 22.1 (Absolute Maximum Ratings) and Table I.1 (Product Lineup) of the Hardware Manual (Rev. 7.02). This extended temperature grade distinguishes it from other SH7750R variants like HD6417750RBP240 (–20°C to +75°C) and is critical for deployment in automotive and industrial environments.

Which serial communication interfaces are integrated into the D6417750RBA240HVU0?

The D6417750RBA240HVU0 integrates two independent serial interfaces: one Serial Communication Interface (SCI) and one Serial Communication Interface with FIFO (SCIF). Both support asynchronous communication; SCIF adds 16-byte transmit/receive FIFOs and higher baud rate capability (up to 15 Mbps), making it suitable for high-speed debug and host communication, while SCI serves legacy peripheral connectivity.
