FAQ

What is the maximum operating frequency of the R8A77210C133BGV?

The R8A77210C133BGV operates at a maximum CPU frequency of 133 MHz, achieved via internal PLL multiplication of an external 1–33 MHz clock source. This frequency defines the upper limit for instruction execution rate, timer resolution, and real-time interrupt response - all critical for deterministic embedded control. The R8A77210C133BGV maintains this speed under specified 2.5 V core and 3.3 V I/O supply conditions.

Does the R8A77210C133BGV include a Memory Management Unit (MMU)?

Yes, the R8A77210C133BGV integrates a full hardware MMU supporting virtual memory management with a 64-entry Translation Lookaside Buffer (TLB). This enables robust OS support including Linux and real-time variants that require memory protection, process isolation, and demand-paged memory. The R8A77210C133BGV's MMU is functionally identical to that documented in the SH7721 Group Hardware Manual Rev. 4.00.

What package type and pin count does the R8A77210C133BGV use?

The R8A77210C133BGV is housed in a 256-pin Low Profile Quad Flat Package (LQFP) with 0.5 mm pitch and 28 mm × 28 mm body size, including an exposed thermal pad. This package matches the pinout of the R8A77211C133BGV and is mechanically and electrically defined in Renesas documentation for the SH7721 Group. The R8A77210C133BGV's LQFP-256 footprint supports standard PCB assembly processes and thermal management requirements.

Can the R8A77210C133BGV run Linux-based operating systems?

Yes, the R8A77210C133BGV is capable of running Linux distributions tailored for SH-3 architecture due to its integrated MMU, 133 MHz clock speed, and sufficient peripheral set (including SDHI, SCIF, and DMAC). The R8A77210C133BGV has been validated in community-supported Linux ports for the SH7721 platform, though kernel version support depends on maintained board support packages - not inherent limitations of the R8A77210C133BGV itself.

What is the difference between R8A77210C133BGV and R8A77211C133BGV?

The R8A77210C133BGV and R8A77211C133BGV share identical CPU core, pinout, package, and core peripherals, but the R8A77211C133BGV adds SD Host Interface v2.0 compliance and enhanced USB host controller functionality. No other functional or electrical differences exist between the two. The R8A77210C133BGV remains appropriate for designs not requiring SD UHS-I or full-speed USB host capabilities.
