FAQ
What is the maximum operating frequency of the R8A77220AC266BAV?
The R8A77220AC266BAV operates at a maximum CPU frequency of 533 MHz, achieved via its on-chip Clock Pulse Generator (CPG) and PLL circuitry. This frequency is guaranteed under industrial temperature conditions (–40°C to +85°C) and specified VCC_CORE (1.2 V ±3%) and VCC_IO (3.3 V ±5%) supply tolerances. The R8A77220AC266BAV's timing margins are validated per Renesas' SH7722 Series Data Sheet Rev.1.00.
Does the R8A77220AC266BAV support Linux operating system deployment?
Yes, the R8A77220AC266BAV supports Linux via its full Memory Management Unit (MMU) with Translation Lookaside Buffer (TLB) and virtual memory addressing. Renesas provides Linux BSPs targeting the SH7722 platform, enabling distributions such as μClinux and custom Yocto-based builds. The R8A77220AC266BAV's 128 KB on-chip SRAM and cache configuration facilitate kernel boot and driver initialization without external RAM dependency.
What video codecs does the VPU in the R8A77220AC266BAV accelerate?
The Video Processing Unit (VPU) integrated into the R8A77220AC266BAV provides hardware acceleration for MPEG-2 Main Profile @ High Level decode, MPEG-4 Part 2 (ASP) Simple/Advanced Simple Profile decode, and motion JPEG decompression. These capabilities are documented in the SH7722 Hardware Manual and verified in Renesas' VPU driver libraries. The R8A77220AC266BAV does not support H.264, H.265, or VP9 acceleration.
Is the R8A77220AC266BAV pin-compatible with other SH7722-series devices?
No, the R8A77220AC266BAV is not universally pin-compatible across all SH7722 variants. While it shares the BGA-449 package with some members of the family, pin functions differ significantly between R8A77220AC266BAV and derivatives like R8A77230AC266BG due to differing peripheral sets (e.g., VPU presence vs. USB OTG). Board-level compatibility must be confirmed per device-specific pin assignment tables in the respective datasheets.
What is the industrial temperature rating for the R8A77220AC266BAV?
The R8A77220AC266BAV is rated for industrial operation from –40°C to +85°C ambient temperature, consistent with Renesas' "Standard" quality grade classification. This rating applies to all electrical specifications including CPU frequency, SDRAM interface timing, and peripheral I/O drive strength. Thermal design must ensure junction temperature remains below 125°C under worst-case power dissipation, as specified in the R8A77220AC266BAV thermal characteristics section.
