It operates at 100 MHz, features three serial interfaces (SCI/SCIF/SIOF), and targets embedded systems requiring real-time control and low-power operation in industrial HMI and networked appliances.

For engineers reviewing the HD6417727BP100CV datasheet, HD6417727BP100CV pinout, HD6417727BP100CV application, or HD6417727BP100CV equivalent, key selection criteria include its 240-pin PQFP package, 100 MHz CPU clock, SDRAM timing support with RAS3/CAS, USB overcurrent detection pins (USB1_ovr_current/USBF_VBUS and USB2_ovr_current), and SH-3 instruction set compatibility.

Technical Context

The HD6417727BP100CV implements the SH-3 CPU core with 8 KB unified cache and memory management unit (MMU) for protected memory operation. It integrates a bus state controller (BSC) for configurable SDRAM timing, including RAS3 and CAS outputs for 64-Mbyte address space mapping.

Its peripheral set includes a four-channel DMAC supporting transfers to SIOF, SCIF, USBF, A/D, D/A, and I/O ports; dual USB host interfaces with dedicated overcurrent detection inputs; and an RTC with separate XTAL2/EXTAL2 oscillator circuitry. Clock modes support crystal resonator (XTAL) or external oscillator input.

FAQ

What is the maximum operating frequency of the HD6417727BP100CV?

The HD6417727BP100CV operates at a maximum CPU clock frequency of 100 MHz. This rating is specified under standard industrial conditions (Vcc = 3.3 V ±0.3 V, Ta = −20°C to +85°C) and assumes stable 3.3 V power delivery and proper decoupling. The actual achievable frequency depends on PCB layout, thermal management, and clock source stability - Renesas recommends verifying timing margins using the BSC register settings and SDRAM setup/hold constraints documented in the Hardware Manual Rev.6.00.

Does the HD6417727BP100CV support SDRAM with 64-Mbyte addressing?

Yes, the HD6417727BP100CV supports 64-Mbyte SDRAM addressing via its dedicated RAS3 and CAS outputs, as confirmed in Section 12.3.2 and Figure 12.11–12.21 of the Hardware Manual Rev.6.00. The RAS3 signal is explicitly used in Area 3 configuration for extended row addressing, and timing parameters for burst/single read/write and auto-refresh are fully specified. HD6417727BP100CV requires correct MCR register programming to enable RAS3 assertion and multiplexed address control.

How does the USB overcurrent detection work on the HD6417727BP100CV?

The HD6417727BP100CV provides two dedicated USB overcurrent detection inputs: pin 123 (USB1_ovr_current/USBF_VBUS) and pin 124 (USB2_ovr_current). These are digital inputs monitored by internal logic to trigger USB host controller fault handling - no internal ADC or threshold setting is involved. The user must connect external current-sense circuitry (e.g., comparator + shunt resistor) to drive these pins low upon overcurrent condition. Both signals are active-low and require external pull-up resistors per Renesas recommendations.

Is the HD6417727BP100CV pin-compatible with other SH7727 variants like the HD6417727BP80?

Yes, the HD6417727BP100CV is pin-compatible with other speed-grade variants in the SH7727 family, including HD6417727BP80 (80 MHz) and HD6417727BP120 (120 MHz), all sharing the PRQP0240KC-B 240-pin PQFP package and identical pinout. Electrical characteristics such as I/O voltage levels, drive strength, and timing parameters scale with rated frequency - the HD6417727BP100CV maintains full functional and mechanical compatibility, allowing frequency upgrades without PCB revision.

What development tools are officially supported for the HD6417727BP100CV?

Renesas officially supports the SuperH™ RISC engine C/C++ Compiler V.9.00, High-Performance Embedded Workshop 3 IDE, and associated debug probes for the HD6417727BP100CV. These tools are validated against the SH-3 instruction set and peripheral register map defined in the SH7727 Hardware Manual Rev.6.00 and SH-3 Software Manual REJ09B0317-0400. Application notes such as REJ05B0463-0400 provide compiler optimization guidance specific to HD6417727BP100CV's cache and DMAC architecture.
