Renesas D6417709SBP100BV

Overview

D6417709SBP100BV from Renesas is a 32-bit RISC microcontroller in the SH7709S Group, featuring the SH-3 CPU core, integrated MMU, on-chip cache, RTC, three serial interfaces (SCI/SCIF), interrupt controller, timer units, and external bus interface supporting SDRAM and PCMCIA. It operates at up to 100 MHz with 2.0 V core supply and targets embedded systems requiring real-time responsiveness and memory management.

For engineers reviewing the D6417709SBP100BV datasheet, D6417709SBP100BV pinout, D6417709SBP100BV application, or D6417709SBP100BV equivalent, this page delivers verified hardware specifications, functional module mapping, package-aware I/O configuration, and validated alternative options for industrial control, network terminal, and multimedia device design.

Technical Context

The D6417709SBP100BV implements the SH-3 instruction set architecture with 5-stage pipeline execution, supports both big- and little-endian memory access, and includes a 4-KB unified instruction/data cache with write-back capability. Its memory management unit provides 64-entry TLB with software- and hardware-managed page translation for protected multitasking environments.

It integrates a programmable bus state controller (BSC) with configurable wait-state generation, synchronous DRAM timing control (CAS latency = 2), and PCMCIA interface compliant with JEIDA 4.2. The chip supports multiple clock operating modes including sleep and module standby, with independent power domains for RTC (VCC–RTC), PLL (VCC–PLL1/VCC–PLL2), and core logic (VCC).

FAQ

What is the maximum supported external bus clock frequency for D6417709SBP100BV?

The D6417709SBP100BV supports a maximum bus clock (Bφ) frequency of 33.34 MHz, as specified in the Hardware Manual Rev. 5.00 Section 9.3. This limit applies to all external memory and peripheral accesses, including SDRAM and PCMCIA interfaces. Exceeding this frequency risks timing violations and data corruption, especially under temperature or voltage variation.

Does D6417709SBP100BV include an integrated memory management unit (MMU)?

Yes, D6417709SBP100BV includes a full-featured MMU with a 64-entry TLB and support for 1 KB, 4 KB, 64 KB, and 1 MB page sizes. This enables virtual memory abstraction, process isolation, and compatibility with Linux and other protected-mode operating systems - a key differentiator versus SH-2 or SH-2A derivatives.

Can D6417709SBP100BV operate with a 1.7 V core supply voltage?

Yes, D6417709SBP100BV is rated for VCC = 1.7 V to 2.0 V, as confirmed in Table 23.2 DC Characteristics (page 659) and Pin Specification Table A.2 (page 723). Operation at 1.7 V is valid across the full commercial temperature range and supports ultra-low-power modes such as module standby with RTC retention.

How many serial communication interfaces does D6417709SBP100BV integrate?

D6417709SBP100BV integrates three independent serial interfaces: two standard SCI modules and one enhanced SCIF module with DMA-triggered transmit/receive capability. All support asynchronous communication at configurable baud rates and include framing error detection and break signal generation - essential for multi-protocol industrial connectivity.

Is the D6417709SBP100BV pin-compatible with other SH7700 Series microcontrollers?

No, D6417709SBP100BV uses the BP-240A 240-ball BGA package, which differs from the FP-208C/FP-208E packages used by earlier SH7709 variants. While functional register sets and instruction compatibility exist within the SH7709S Group, physical pinout, power domain assignment, and peripheral multiplexing are specific to this variant - PCB layout is not interchangeable.
