FAQ

What is the maximum operating frequency of the R7S721010VCBG#AC0?

The R7S721010VCBG#AC0 operates at a maximum CPU frequency of 400 MHz under specified voltage (1.2 V core) and temperature (−40°C to +85°C) conditions. This frequency is achieved using the on-chip PLL with fractional divider and is validated per the RZ/A1H Hardware User's Manual Rev.7.00. The R7S721010VCBG#AC0 does not support dynamic frequency scaling beyond this rated speed.

Does the R7S721010VCBG#AC0 support DDR3 or DDR3L memory?

The R7S721010VCBG#AC0 supports DDR3L (Low Voltage) memory only, with VDDQ = 1.35 V nominal. It does not support standard DDR3 (1.5 V) operation. The DDR3L interface is 16-bit wide and capable of 800 MT/s data rates, as confirmed in the Memory Controller section of the RZ/A1H Hardware User's Manual. The R7S721010VCBG#AC0 requires strict adherence to DDR3L timing parameters and termination schemes.

What boot sources are supported by the R7S721010VCBG#AC0?

The R7S721010VCBG#AC0 supports four primary boot sources determined by the BOOT[3:0] strap pins: SPI NOR flash, NAND flash, SD card, and serial interface (UART/I²C). Boot mode selection is latched at power-on reset and cannot be changed dynamically. The R7S721010VCBG#AC0 includes on-chip ROM bootloader with built-in drivers for all supported interfaces and validates image integrity before execution.

Is the R7S721010VCBG#AC0 pin-compatible with other RZ/A1H variants?

Yes, the R7S721010VCBG#AC0 is fully pin-compatible with other members of the RZ/A1H Group in the same 324-pin LQFP package, including R7S721020VCBG#AC0 and R7S721030VCBG#AC0. All share identical pin assignments, electrical characteristics, and mechanical footprint per the RZ/A1H Hardware User's Manual Rev.7.00. This allows direct PCB reuse across variants when memory or feature requirements evolve.

Does the R7S721010VCBG#AC0 include hardware cryptographic acceleration?

Yes, the R7S721010VCBG#AC0 integrates dedicated hardware accelerators for AES-128/192/256, SHA-1/256, and RSA-1024/2048 operations. These accelerators are accessible via the Crypto IP block and operate independently of the Cortex-A9 cores, enabling high-throughput encryption without CPU overhead. The R7S721010VCBG#AC0 uses these engines for secure boot, firmware signature verification, and TLS offload in Linux environments.
