Renesas HD6417708SF60

Overview

HD6417708SF60 from Renesas Electronics is a 32-bit SuperH™ RISC microcontroller (SH-3 core) with on-chip MMU, 8 KB unified cache, RTC, SCI, timers, and interrupt controller - operating at 60 MHz with 3.3 V supply. It targets embedded control systems requiring virtual memory support and real-time peripheral integration, such as industrial HMIs and networked gateways.

For engineers reviewing the HD6417708SF60 datasheet, HD6417708SF60 pinout, HD6417708SF60 application, or HD6417708SF60 equivalent, key selection criteria include its SH-3 instruction compatibility, 60 MHz max clock, 3.3 V I/O voltage, 208-pin PQFP package, and integrated memory management unit for OS-based designs.

Technical Context

The HD6417708SF60 implements the SH-3 CPU core with a 5-stage pipeline, single-cycle basic instruction execution, and a 32×32→64-bit hardware multiplier. Its on-chip MMU supports 4 GB virtual address space translation via 64-entry TLB with software-managed page tables.

It integrates a bus state controller (BSC) enabling direct interface to SDRAM, DRAM, and pseudo-SRAM without external glue logic, alongside a user break controller (UBC) for in-circuit debugging and a real-time clock with calendar function.

FAQ

What is the maximum operating frequency of the HD6417708SF60?

The HD6417708SF60 operates at a maximum clock frequency of 60 MHz, as specified in the Renesas SH7708 Series Hardware Manual Rev.9.0. This frequency is achieved using an external 60 MHz clock source applied to the CLKIN pin, with internal PLL circuitry generating the core clock. The 60 MHz rating applies under standard 3.3 V supply and commercial temperature conditions (0°C to +70°C).

Does the HD6417708SF60 include an on-chip memory management unit (MMU)?

Yes, the HD6417708SF60 integrates a full-featured MMU with a 64-entry Translation Lookaside Buffer (TLB), supporting 4 GB virtual address space mapping to physical memory. This MMU enables HD6417708SF60 to run protected-mode operating systems such as μClinux or VxWorks, providing memory isolation between processes and facilitating robust firmware architecture in safety-aware applications.

What package type and pin count does the HD6417708SF60 use?

The HD6417708SF60 uses a 208-pin Plastic Quad Flat Package (PQFP) with 0.65 mm lead pitch and 28 mm × 28 mm body size. This package is RoHS-compliant and designed for standard surface-mount reflow assembly. Pin assignments match the SH7708 Series specification in Renesas Hardware Manual Section 1.3, ensuring mechanical and electrical compatibility within the family.

Is the HD6417708SF60 pin-compatible with other SH7708 Series variants?

Yes, the HD6417708SF60 is pin-compatible with the HD6417708S and HD6417708R variants, all sharing the same 208-pin PQFP footprint and identical pin functions. Differences between these variants lie in internal configuration (e.g., mask ROM content, boot mode settings) rather than pinout or electrical characteristics - allowing drop-in replacement in existing PCB layouts where firmware compatibility is maintained.

What peripheral modules are integrated into the HD6417708SF60?

The HD6417708SF60 integrates a real-time clock (RTC) with calendar function, serial communication interface (SCI), 32-bit timers with PWM capability, interrupt controller (INTC), user break controller (UBC), bus state controller (BSC), and oscillation circuit. These modules eliminate the need for discrete support ICs in typical embedded control applications, reducing system complexity and bill-of-materials cost.
