Renesas D6417751RBP200DV

Overview

HD6417751RBP200DV from Renesas Electronics is a 32-bit RISC microprocessor based on the SH-4 core, featuring a 240 MHz-capable SH7751R architecture operating at 200 MHz, integrated FPU, MMU, PCI controller (PCIC), and dual serial interfaces (SCI/SCIF), used in multimedia terminals and industrial embedded systems requiring high-throughput real-time processing.

For engineers reviewing the HD6417751RBP200DV datasheet, HD6417751RBP200DV pinout, HD6417751RBP200DV application, or HD6417751RBP200DV equivalent, key selection criteria include internal PLL voltage requirements (VDD-PLL1/VDD-PLL2), PCI bus timing compliance (PCI Rev. 2.1 subset), cache configuration modes (IC/OC sizing and RAM mode), and hardware standby power sequencing for RTC retention.

Technical Context

The HD6417751RBP200DV implements a superscalar SH-4 CPU with parallel two-instruction execution, 16-KB instruction cache and 32-KB operand cache (half configurable as on-chip RAM), and full memory management via MMU with ITLB/UTLB support. It integrates a floating-point unit compliant with IEEE 754 single/double precision and includes 3-D graphics acceleration instructions (FTRV, FIPR).

Its bus architecture supports separate 26-bit address/32-bit data SH buses plus a 32-bit multiplexed PCI bus interface, with BSC enabling direct connection to DRAM, SDRAM, SRAM, and PCMCIA. The device operates at 1.5 V core supply and requires dedicated PLL and RTC power domains (VDD-PLL1/2, VDD-RTC) regardless of functional usage.

Key Specifications

Pinout & Package

HD6417751RBP200DV is housed in a 256-pin fine-pitch ball grid array (BGA) package with 1.0 mm pitch, thermal pad exposed on underside, and standard JEDEC MO-251AC footprint. Power delivery requires dedicated routing for VDD-PLL1/2, VDD-CPG/RTC, and VSS-PLL/RTC pins per Renesas hardware guidelines.

FAQ

What is the core voltage requirement for HD6417751RBP200DV?

The HD6417751RBP200DV requires a nominal 1.5 V core supply (VDD) with tight regulation (±3%). Additionally, dedicated 1.5 V supplies must be provided to VDD-PLL1 and VDD-PLL2 pins-even when the PLL is not used-to ensure clock stability and prevent startup failure. Failure to supply these rails causes undefined reset behavior and potential latch-up.

Does HD6417751RBP200DV support PCI Express or only legacy PCI?

The HD6417751RBP200DV implements a PCI controller compliant with a subset of PCI Revision 2.1, supporting only conventional 32-bit, 33 MHz parallel PCI-not PCI Express. It provides memory-mapped and I/O-space transactions, bus mastering, and interrupt assertion via INTA, but lacks PCIe packet-based protocol, lanes, or configuration space extensions.

Can the operand cache in HD6417751RBP200DV be used entirely as SRAM?

No. The HD6417751RBP200DV allows only half (16 KB) of its 32 KB operand cache to be configured as on-chip RAM via the ORA bit in the CCR register when OCE = 1. The remaining 16 KB remains functional as cache. Full conversion to SRAM is not supported-this is a fixed hardware partition, not a software-configurable memory region.

What is the function of the CKIO pin on HD6417751RBP200DV?

The CKIO pin on HD6417751RBP200DV outputs a synchronous clock derived from the internal PLL, intended for driving external DRAM or SDRAM chips. Its frequency is programmable via the BSC registers and matches the selected memory interface timing-e.g., 100 MHz for DDR SDRAM or 66 MHz for standard SDRAM-ensuring precise setup/hold alignment for memory transactions.

Is HD6417751RBP200DV qualified for automotive applications?

No. HD6417751RBP200DV is classified as a "Standard" quality grade device per Renesas documentation, intended for office equipment, communications gear, and industrial robots-not automotive safety-critical systems. It lacks AEC-Q100 qualification, extended temperature range (-40°C to +125°C), or fault-tolerant design features required for automotive use.
