Renesas D6417709SF100BV

Overview

D6417709SF100BV from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-3 CPU core, featuring an integrated MMU, cache memory, real-time clock (RTC), three serial interfaces (SCI/SCIF), timer units, interrupt controller, and bus state controller - operating at up to 100 MHz with 2.0 V core supply and supporting little/big-endian memory access for embedded control applications in industrial and office equipment.

For engineers reviewing the D6417709SF100BV datasheet, D6417709SF100BV pinout, D6417709SF100BV application, or D6417709SF100BV equivalent, key selection considerations include its 208-pin FP package, 100 MHz maximum CPU frequency, 2.0 V/1.9 V/1.8 V/1.7 V multi-rail power support, integrated memory management unit, and compatibility with SH-3 instruction set architecture for legacy real-time OS and firmware porting.

Technical Context

The D6417709SF100BV implements the SH-3 CPU core with 5-stage pipeline execution, 8 KB unified instruction/data cache, and memory management unit supporting virtual-to-physical address translation via 64-entry TLB. It integrates on-chip peripherals including three asynchronous serial interfaces (SCI/SCIF), four 32-bit timers (TMU), RTC with calendar function, UBC (user break controller), and BSC (bus state controller) for flexible external memory mapping.

It supports multiple clock modes via FRQCR register, with programmable Iφ/Bφ ratios (e.g., 1:1, 2:1, 3:1), PLL-based clock generation, and low-power states including sleep and module standby - requiring explicit register access before entering RTC standby. The device uses separate power domains for VCC (core), VCC–RTC (2.0/1.9/1.8/1.7 V), and VCC–PLL1/PLL2 (2.0/1.9/1.8/1.7 V).

FAQ

What is the maximum operating frequency of the D6417709SF100BV?

The D6417709SF100BV operates at a maximum CPU frequency of 100 MHz. This is achieved using the internal PLL driven by the CKIO input clock, which must be ≤33.34 MHz. The device supports configurable Iφ/Bφ clock ratios (e.g., 1:1, 2:1, 3:1) via the FRQCR register, enabling performance scaling while maintaining bus timing integrity. The 100 MHz rating applies under specified VCC (2.0 V) and temperature conditions per Renesas' DC characteristics table.

Does the D6417709SF100BV include a memory management unit (MMU)?

Yes, the D6417709SF100BV includes a full-featured memory management unit (MMU) with a 64-entry translation lookaside buffer (TLB). This MMU supports virtual-to-physical address translation, memory protection, and page-level access control - enabling safe multitasking operating systems such as μITRON or Linux derivatives. The MMU is integral to the SH-3 core architecture and is fully documented in the SH7709S Hardware Manual Rev. 5.00.

What power supply voltages does the D6417709SF100BV require?

The D6417709SF100BV requires three distinct voltage domains: VCC (core logic, 2.0/1.9/1.8/1.7 V), VCC–RTC (real-time clock domain, same voltage range), and VCC–PLL1/PLL2 (PLL circuits, same range). Each domain must be independently decoupled. The absolute maximum ratings specify that all supplies must stabilize before releasing RESETP, and VCC–RTC must remain powered during sleep to retain RTC state.

How many serial communication interfaces does the D6417709SF100BV support?

The D6417709SF100BV supports three asynchronous serial interfaces: two standard SCI modules and one enhanced SCIF module. All three support programmable baud rates, full-duplex operation, framing/error detection, and DMA-triggered data transfer via associated interrupt flags (TDFE/RDF). The SCIF adds FIFO buffering and deeper trigger thresholds, making it suitable for high-throughput host communication.

Is the D6417709SF100BV pin-compatible with other SH7700 Series microcontrollers?

No, the D6417709SF100BV is not pin-compatible with other SH7700 Series variants such as SH7705 or SH7706. While sharing the SH-3 core and functional similarities, pin assignments differ significantly - especially for peripheral signals like CSn, BUSREQ, and DMAC request lines. The FP-208C/E package is specific to the SH7709S group, and migration requires PCB redesign and firmware adaptation due to register map and interrupt vector differences.
