Renesas HD6417750F167D

Overview

HD6417750F167D from Renesas Electronics is a 32-bit RISC microprocessor in the SH7750S Group, implementing the SH-4 CPU core with integrated MMU, 16 KB instruction cache, 16 KB operand cache, and peripheral functions including dual serial interfaces (SCI/SCIF), RTC, UBC, BSC, and smart card interface. It operates at 167 MHz with 1.8 V core voltage and targets multimedia system-on-chip applications requiring real-time processing and memory management.

For engineers reviewing the HD6417750F167D datasheet, HD6417750F167D pinout, HD6417750F167D application, or HD6417750F167D equivalent, key selection criteria include its 208-pin QFP package, 167 MHz clock frequency, 1.8 V core supply, -20°C to +75°C operating temperature range, and compatibility with DRAM, SDRAM, and PCMCIA bus protocols.

Technical Context

The HD6417750F167D implements the SH-4 superscalar RISC architecture with five-stage pipeline, dual-issue capability, and IEEE 754-compliant floating-point unit. It integrates a 32-bit external data bus, 32-bit address bus, and supports big-endian memory organization.

Its memory management unit provides full virtual memory support with unified TLB, 64-entry ITLB, and 256-entry UTLB. The bus state controller enables direct interfacing with ROM, SRAM, DRAM, synchronous DRAM (including 64-bit 4-bank SDRAM), and PCMCIA devices without external glue logic.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating temperature specification for HD6417750F167D?

The HD6417750F167D is rated for operation from –20°C to +75°C ambient temperature. This specification applies to the standard version documented in the R01UH0456EJ0702 Rev. 7.02 Hardware Manual. Extended temperature variants (–40°C to +85°C) are available under different part numbers such as HD6417750RBA240HV, but HD6417750F167D itself does not support the extended range.

Does HD6417750F167D support DDR SDRAM directly?

HD6417750F167D does not support DDR SDRAM natively. Its bus state controller (BSC) supports standard SDRAM (including 64-bit 4-bank configurations) and asynchronous memory types, but lacks the DLL, bidirectional DQS, and command encoding required for DDR. Designers must use external memory controller ASICs or FPGAs to interface DDR SDRAM with HD6417750F167D.

Is the smart card interface on HD6417750F167D compliant with ISO/IEC 7816-3?

Yes, the smart card interface on HD6417750F167D implements full hardware support for ISO/IEC 7816-3 asynchronous T=0 protocol, including automatic guard time insertion, character parity checking, and clock frequency adaptation. It does not support T=1 or contactless protocols - those require external co-processors or dedicated secure elements.

What debug capabilities does HD6417750F167D provide?

HD6417750F167D includes a User Break Controller (UBC) supporting hardware breakpoints, watchpoints, and trace trigger events. It works with Renesas E1/E20 emulators and compatible JTAG debuggers. The UBC supports up to four independent address-match conditions and integrates with the SH-4's on-chip debug architecture for non-intrusive real-time analysis without software instrumentation.

Can HD6417750F167D execute code directly from external NOR flash without copying to RAM?

Yes, HD6417750F167D supports XIP (eXecute-In-Place) from external NOR flash via its bus state controller. The BSC allows configurable wait states, burst length, and access timing to match flash characteristics. However, instruction cache coherency must be managed manually when flash contents change - the cache does not auto-invalidate on external writes.
