FAQ

What is the primary CPU architecture used in the HD6417727BP160CV?

The HD6417727BP160CV implements the SH-3 32-bit RISC CPU core, delivering deterministic real-time performance with instruction-level compatibility across the SuperH™ family. This architecture supports MMU-based virtual memory, enabling robust multitasking operating systems. The HD6417727BP160CV's SH-3 core operates up to 160 MHz and integrates tightly with on-chip peripherals including DMAC, USB controllers, and SDRAM interface logic.

Does the HD6417727BP160CV support both USB host and USB device functionality?

Yes, the HD6417727BP160CV supports dual USB host mode and USB function (device) mode. Pin 123 serves as bidirectional USB1_ovr_current/USBF_VBUS, enabling overcurrent detection in host mode and VBUS sensing in function mode. The chip includes dedicated USB function controller logic, allowing it to emulate standard USB classes such as CDC or MSC without external PHY. This dual-role capability is confirmed in the SH7727 Hardware Manual Rev.6.00 section 14.1 and pin function table.

What package type and pin count does the HD6417727BP160CV use?

The HD6417727BP160CV uses a 240-pin plastic quad flat pack (PQFP) package designated PRQP0240KC-B. This surface-mount package features 0.5 mm lead pitch and is compatible with standard reflow soldering processes. The pin arrangement includes dedicated signals for SDRAM control (RAS3, CKE), USB overcurrent detection (pins 123 and 124), and RTC oscillator (XTAL2/EXTAL2), as documented in Figures 1.2 and 1.3 of the Renesas SH7727 Hardware Manual.

How does the HD6417727BP160CV handle synchronous DRAM addressing for 64-Mbyte configurations?

The HD6417727BP160CV supports 64-Mbyte SDRAM addressing using the RAS3 signal (pin 129) in conjunction with CAS and CKE. When configured for Area 3 memory mapping, the MCR register enables RAS3 assertion alongside CAS and RD/WR to manage row/column addressing and timing. This capability is explicitly detailed in Section 12.3.2 and Figure 12.11–12.21 of the SH7727 Hardware Manual, distinguishing it from earlier SH77xx variants lacking RAS3.

Is the HD6417727BP160CV qualified for automotive or safety-critical applications?

No, the HD6417727BP160CV is classified as a Standard quality grade device per Renesas documentation, intended for computers, office equipment, communications gear, and industrial robots-not automotive, aerospace, or life-support systems. Renesas explicitly states that products not designated for automobile applications are unsuitable for safety-critical use without prior written consent. The HD6417727BP160CV datasheet contains no AEC-Q100 qualification data or extended temperature range ratings required for automotive deployment.
