FAQ

What is the maximum operating frequency of the R7S721001VCBG#AC1?

The R7S721001VCBG#AC1 operates at a maximum CPU frequency of 600 MHz under specified thermal and voltage conditions (VDD = 1.15 V ± 3%, junction temperature ≤ 105°C). This frequency is achieved using the on-chip PLL with programmable dividers and is validated across process corners per Renesas' AC characteristics table in the Hardware User's Manual Rev.7.00.

Does the R7S721001VCBG#AC1 support TrustZone security?

Yes, the R7S721001VCBG#AC1 integrates ARM TrustZone technology at the silicon level, enabling hardware-isolated secure and normal worlds. The R7S721001VCBG#AC1 implements TrustZone Address Space Controllers (TZASC), TrustZone Protection Controllers (TZPC), and secure boot ROM to enforce memory and peripheral access separation - confirmed in Section 1.1 "Features of This LSI" and Chapter 12 "Security Functions" of the RZ/A1H Hardware User's Manual.

What boot media does the R7S721001VCBG#AC1 support natively?

The R7S721001VCBG#AC1 supports four native boot sources selected via BOOT[3:0] pins: Quad SPI flash (QSPI), SD/MMC card, USB host (mass storage class), and UART (for recovery flashing). Each mode is implemented in the on-chip ROM bootloader and documented in Section 3 "Boot Mode" of the Hardware User's Manual, with no external firmware required to initiate execution.

Is the R7S721001VCBG#AC1 pin-compatible with other RZ/A1H variants?

Yes, the R7S721001VCBG#AC1 shares identical 516-pin FBGA packaging and pin assignment with all RZ/A1H Group MPUs including R7S721021VCBG#AC1 and R7S721031VCBG#AC1. Pin functions, power domains, and signal timing are fully compatible per Section 1.4 "Pin Assignment" and Table 1.1 "Pin List" in the Hardware User's Manual Rev.7.00.

What display interfaces does the R7S721001VCBG#AC1 integrate?

The R7S721001VCBG#AC1 integrates a dual-channel 24-bit RGB LCD controller supporting up to 1920×1080 resolution at 60 Hz, plus hardware overlay blending, alpha blending, and gamma correction. It also supports MIPI DSI through external bridge ICs, as detailed in Section 1.1 and Chapter 11 "LCD Controller" of the Hardware User's Manual.
