Renesas HD6417727X100CV

Overview

HD6417727X100CV from Renesas Electronics is a 32-bit SH-3 RISC microprocessor with integrated MMU, 4-channel DMAC, USB host (dual-port), RTC, and SDRAM interface supporting RAS3/CAS for 64-Mbyte addressing. It operates at 100 MHz, features cache memory, and targets embedded control systems requiring real-time I/O handling and low-power operation.

For engineers reviewing the HD6417727X100CV datasheet, HD6417727X100CV pinout, HD6417727X100CV application, or HD6417727X100CV equivalent, this page delivers verified technical context, pin-level interface roles, timing-critical peripheral specifications, and validated alternative options for industrial HMI, networked instrumentation, and USB-enabled embedded controllers.

Technical Context

The HD6417727X100CV implements the SH-3 CPU core with 32-bit address/data bus, on-chip memory management unit (MMU), and bus state controller (BSC) for configurable SDRAM timing including RAS3/CAS multiplexing and DQM-based byte masking. It supports clock mode 7 with external PLL oscillator configuration via EXTAL/XTAL pins.

Peripheral integration includes three serial interfaces (SCI, SCIF, SIOF), dual USB host controllers with overcurrent detection (USB1_ovr_current/USBF_VBUS and USB2_ovr_current), real-time clock with dedicated XTAL2/EXTAL2 inputs, and smart card interface compliant with ISO/IEC 7816-3 T=0 protocol.

FAQ

What is the maximum operating frequency of the HD6417727X100CV?

The HD6417727X100CV operates at a maximum clock frequency of 100 MHz. This rating is specified under standard industrial temperature range (–40°C to +85°C) and 3.3 V ±0.3 V supply conditions per the Renesas SH7727 Hardware Manual Rev.6.00. The HD6417727X100CV achieves this speed using its internal PLL with external crystal input on XTAL pin, and timing-critical paths are validated for worst-case voltage and temperature corners.

Does the HD6417727X100CV support USB device mode?

No, the HD6417727X100CV supports USB host mode only - it integrates two USB 1.1 host controllers with dedicated overcurrent detection pins (USB1_ovr_current/USBF_VBUS and USB2_ovr_current), but lacks USB device or OTG functionality. The HD6417727X100CV does not include a USB transceiver capable of device enumeration or VBUS sensing in device role, and no USB device-mode registers or descriptors are defined in its peripheral register map.

What SDRAM configurations are supported by the HD6417727X100CV?

The HD6417727X100CV supports 64-Mbyte SDRAM addressing using RAS3 and CAS signals with programmable timing via the Memory Control Register (MCR). It drives standard x16 or x32 SDRAM devices with burst lengths of 1, 2, 4, or 8, and supports auto-refresh and self-refresh modes. The HD6417727X100CV's SDRAM interface requires no external address latch due to integrated RAS3/CAS generation and multiplexed address/data bus control.

Is the HD6417727X100CV pin-compatible with other SH7727 variants?

Yes, the HD6417727X100CV shares identical pinout and package (PLBG0240JA-A) with other SH7727 variants including HD6417727T100 and HD6417727X120, differing only in speed grade and marking. All SH7727 devices use the same 240-pin LGA footprint, identical pin functions per Table 1.2 in the hardware manual, and require identical PCB layout - enabling drop-in replacement for frequency or temperature grade changes without board revision.

What is the role of the Scan_testen pin on the HD6417727X100CV?

The Scan_testen pin (Pin 224) enables IEEE 1149.1 boundary-scan testing on the HD6417727X100CV. It is an input pin internally pulled up to VccQ; for normal operation, it must be held high (≥2.7 V). During JTAG test, it is driven low to activate scan chain visibility. Leaving Scan_testen floating or pulling it low during runtime causes undefined behavior and may disrupt internal logic states - the HD6417727X100CV datasheet explicitly prohibits this condition.
