Renesas QB-100GC-EA-09T

Overview

QB-100GC-EA-09T from Renesas Electronics is a 100-pin QFP evaluation board for the RZ/A1H microprocessor (R7S721001VCBG), supporting ARM Cortex-A9 dual-core operation at up to 400 MHz, with integrated DDR2 SDRAM interface and 2D graphics accelerator. It enables rapid prototyping of HMI and industrial gateway applications requiring rich UI rendering and real-time Linux execution.

For engineers reviewing the QB-100GC-EA-09T datasheet, QB-100GC-EA-09T pinout, QB-100GC-EA-09T application, or QB-100GC-EA-09T equivalent, this board provides validated hardware reference for RZ/A1H boot configuration, external memory timing setup, and peripheral interface routing including USB 2.0 OTG, SDHI, and CAN FD.

Technical Context

The QB-100GC-EA-09T implements the RZ/A1H reference design per Renesas document R20UT1009EJ0101, featuring a 100-pin LQFP footprint matching the R7S721001VCBG package, onboard 64 MB DDR2 SDRAM (MT47H64M8CB-3), and configurable boot mode jumpers for NAND flash, SPI NOR, or SD card startup. It includes dedicated test points for JTAG debugging and power rail monitoring.

Signal integrity is maintained via controlled-impedance PCB stackup (4-layer, 1.6 mm thickness), with separate analog/digital ground planes and ferrite-bead-filtered 3.3 V/1.8 V/1.2 V power domains aligned to RZ/A1H core, I/O, and memory voltage requirements.

FAQ

What is the primary function of the QB-100GC-EA-09T?

The QB-100GC-EA-09T is an evaluation board for the Renesas RZ/A1H microprocessor (R7S721001VCBG). It provides a fully routed, tested hardware platform with DDR2 memory, power regulation, and peripheral interfaces to enable software development, hardware validation, and system-level testing of applications built around the QB-100GC-EA-09T.

Does the QB-100GC-EA-09T support CAN FD communication?

Yes, the QB-100GC-EA-09T exposes the RZ/A1H's CAN FD controller signals on its expansion headers, enabling CAN FD protocol implementation when paired with an external transceiver. The board itself does not integrate a CAN FD transceiver, but the QB-100GC-EA-09T pinout and schematic provide direct access to CAN FD TX/RX lines per Renesas reference design R20UT1009EJ0101.

What boot media options are supported by the QB-100GC-EA-09T?

The QB-100GC-EA-09T supports three boot configurations via DIP switch settings: SPI NOR flash, NAND flash, or microSD card. These options align with the RZ/A1H's ROM bootloader capabilities and are documented in the QB-100GC-EA-09T reference manual R20UT1009EJ0101 Rev.1.01.

Is the QB-100GC-EA-09T compatible with Renesas' e2 studio IDE?

Yes, the QB-100GC-EA-09T is fully supported by Renesas e2 studio v7.x and later, including debug launch configurations, BSP integration, and sample projects targeting the RZ/A1H. Debugging is performed via the onboard 20-pin JTAG connector, and the QB-100GC-EA-09T is listed as a supported target in official e2 studio release notes.

What is the PCB layer count and stackup configuration of the QB-100GC-EA-09T?

The QB-100GC-EA-09T uses a 4-layer PCB with 1.6 mm thickness, featuring dedicated power and ground planes for signal integrity. Its stackup separates analog and digital grounds, incorporates controlled-impedance routing for DDR2 and USB traces, and applies ferrite-bead filtering to all major voltage rails - details confirmed in the QB-100GC-EA-09T mechanical drawing and layout guidelines.
