Renesas D17709SHF167BDV

Overview

D17709SHF167BDV from Renesas is a 32-bit RISC microcontroller based on the SuperH™ SH-3 CPU core, featuring an integrated MMU, 8 KB unified cache, real-time clock (RTC), three serial interfaces (SCI/SCIF), timer units (TMU), interrupt controller (INTC), and bus state controller (BSC). It operates at up to 167 MHz with 1.9 V core supply and targets embedded systems requiring deterministic real-time performance and memory management.

For engineers reviewing the D17709SHF167BDV datasheet, D17709SHF167BDV pinout, D17709SHF167BDV application, or D17709SHF167BDV equivalent, key selection criteria include SH-3 instruction set compatibility, 208-pin FP-BGA package footprint, synchronous DRAM interface support, module standby power control, and PCMCIA host controller capability.

Technical Context

The D17709SHF167BDV implements the SH-3E architecture with 5-stage pipeline execution, little-endian memory addressing, and privileged/supervisor/user mode operation. It integrates a 32-bit external bus interface supporting burst ROM, synchronous DRAM, and PCMCIA memory card access with configurable wait states and bank control.

Its memory management unit (MMU) provides 64-entry TLB with page-level protection and virtual-to-physical address translation, while the on-chip cache uses write-through policy with software-controlled invalidation per entry or full array. Clock generation supports dynamic frequency scaling via FRQCR register with Iφ/Bφ ratio control.

FAQ

What is the maximum operating frequency of the D17709SHF167BDV?

The D17709SHF167BDV operates at a maximum CPU frequency of 167 MHz, derived from its internal PLL that multiplies the 33.34 MHz maximum CKIO input clock. This frequency is sustained under specified 1.9 V core supply and ambient temperature conditions, and is validated in the SH7709S Hardware Manual Rev. 5.00. The D17709SHF167BDV's bus clock (Bφ) runs at 33 MHz, enabling high-throughput external memory access while maintaining timing margins for synchronous DRAM and PCMCIA interfaces.

Does the D17709SHF167BDV include a memory management unit (MMU)?

Yes, the D17709SHF167BDV integrates a full-featured MMU with a 64-entry Translation Lookaside Buffer (TLB), supporting virtual-to-physical address translation, page-level protection, and memory isolation. This MMU enables certified real-time operating systems like μITRON and embedded Linux to run securely on the D17709SHF167BDV, making it suitable for applications requiring task protection and dynamic memory allocation-such as industrial HMIs and medical data loggers where firmware integrity is critical.

What package type and pin count does the D17709SHF167BDV use?

The D17709SHF167BDV is packaged in a 208-pin Fine-Pitch Ball Grid Array (FP-208C/E) with 1.0 mm ball pitch and a 17 mm × 17 mm body size. This package supports high-density PCB layouts while providing dedicated power/ground balls for noise reduction and thermal dissipation. Pin assignments are documented in Section 1.3 of the SH7709S Hardware Manual Rev. 5.00, including separate VCC, VCC–RTC, and VCC–PLL supplies to ensure signal integrity across mixed-signal domains within the D17709SHF167BDV.

Can the D17709SHF167BDV interface directly with synchronous DRAM?

Yes, the D17709SHF167BDV includes a dedicated synchronous DRAM interface supporting 32-bit bus width, auto-precharge, and bank-active modes. Configuration is managed via the MCS[0–7] control registers and MCR register, with timing parameters programmable to match specific SDRAM parts. The D17709SHF167BDV's hardware handles row/column address multiplexing and refresh cycles, eliminating the need for external DRAM controller logic-reducing BOM cost and board area in memory-intensive applications such as data acquisition systems.

Is the D17709SHF167BDV suitable for battery-powered applications with long uptime requirements?

Yes, the D17709SHF167BDV supports multiple low-power states including module standby, where individual peripherals (RTC, SCI, TMU) can be powered down independently while the CPU remains active. Its RTC operates from a separate 1.7–2.0 V supply (VCC–RTC) and retains time/date/alarm functions during main power loss. Measured current in sleep mode is as low as 10–20 µA (IccQ), enabling years of operation on coin-cell backup-making the D17709SHF167BDV well-suited for portable medical loggers and remote industrial sensors requiring persistent timekeeping without external RTC ICs.
