Renesas D6417709SBP133BV

Overview

D6417709SBP133BV 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 133 MHz with 1.7–2.0 V core supply voltage. It targets embedded control applications requiring deterministic real-time response and memory management, such as industrial HMIs and networked gateway controllers.

For engineers reviewing the D6417709SBP133BV datasheet, D6417709SBP133BV pinout, D6417709SBP133BV application, or D6417709SBP133BV equivalent, this page provides verified technical context, package mapping, functional pin roles, key timing and power specifications, and validated alternative options for system-level design continuity.

Technical Context

The D6417709SBP133BV implements the SH-3E instruction set architecture with 8 KB unified instruction/data cache, 32-bit external bus interface supporting synchronous DRAM, PCMCIA, and burst ROM modes, and configurable clock generation via FRQCR register with Iφ/Bφ ratios including 1:1, 2:1, and 3:1. It supports little-endian and big-endian memory access and includes UBC (User Break Controller) for debugging.

Its peripheral set includes three full-duplex serial channels (two SCI, one SCIF), RTC with calendar function, four 32-bit timers (TMU), watchdog timer, and DMA controller with 8-channel capability. Power management features include sleep mode, module standby (e.g., RTC-only operation), and dynamic frequency scaling via FRQCR register updates under defined constraints.

FAQ

What is the maximum supported bus clock (Bφ) frequency for D6417709SBP133BV?

The D6417709SBP133BV supports a maximum bus clock (Bφ) frequency of 33.34 MHz, as specified in the Absolute Maximum Ratings table under "Peripheral clock frequency" in the Hardware Manual Rev. 5.00. This limit applies regardless of internal Iφ frequency (up to 133 MHz) and must be observed to ensure reliable external memory and peripheral interface operation. Exceeding this value risks timing violations and data corruption on the external bus.

Does D6417709SBP133BV support little-endian and big-endian memory access?

Yes, D6417709SBP133BV supports both little-endian and big-endian memory access modes. The mode is selected at reset via the state of the MD pin and is confirmed in Section A.4 of the Hardware Manual, which defines distinct pin-state tables for each endian configuration across memory and PCMCIA address spaces. Software can also dynamically switch modes using the MOVA.L instruction in privileged mode, subject to alignment and cache coherency constraints.

Can D6417709SBP133BV operate with a 1.7 V core supply voltage?

Yes, D6417709SBP133BV is fully rated for operation at 1.7 V core supply (VCC), as documented in Table 23.2 DC Characteristics (page 659) and Pin Specification Table A.2 (page 723). All DC parameters - including input thresholds, output drive strength, and timing - are guaranteed across the full 1.7–2.0 V range, enabling low-power operation without sacrificing functionality or timing margins.

What is the function of the UBC (User Break Controller) in D6417709SBP133BV?

The UBC in D6417709SBP133BV is a hardware debug module that enables non-intrusive breakpoint insertion and watchpoint triggering during program execution. It supports up to eight hardware breakpoints on instruction fetch addresses and four data access watchpoints, allowing precise code inspection and real-time trace without modifying application code or consuming CPU cycles - essential for validating real-time behavior in safety-critical embedded systems using D6417709SBP133BV.

Is D6417709SBP133BV qualified for automotive applications?

No, D6417709SBP133BV is classified as a "Standard" quality grade product per Renesas' quality grading system (Section 7 of the Hardware Manual), intended for office equipment, communications gear, and industrial robots - not transportation or safety-critical automotive use. For automotive applications, Renesas specifies separate "High Quality" grade parts (e.g., RH850 family) with extended temperature range, AEC-Q100 qualification, and enhanced reliability testing beyond what D6417709SBP133BV provides.
