For engineers reviewing the R8A77210C133BAV datasheet, R8A77210C133BAV pinout, R8A77210C133BAV application, or R8A77210C133BAV equivalent, this page provides verified hardware specifications, functional module mapping, package configuration (LQFP-256), and validated alternative options for industrial HMI, automotive body control, and networked gateway designs.

Technical Context

The R8A77210C133BAV implements the SH-3E CPU core with 5-stage pipeline, 32-bit address/data bus, and full MMU supporting virtual memory via TLB-based translation. It integrates dual 16 KB caches (instruction and data), a Clock Pulse Generator (CPG) with PLL, and multiple DMA channels for high-throughput peripheral-to-memory transfers.

Peripheral subsystems include Serial Communication Interface with FIFO (SCIF), Compare Match Timer (CMT), Timer Pulse Unit (TPU), SD Host Interface (SDHI), and Interrupt Controller (INTC) with 128 vector entries. All modules are memory-mapped and accessible via the internal bus matrix without external glue logic.

FAQ

What is the maximum operating frequency of the R8A77210C133BAV?

The R8A77210C133BAV operates at a maximum frequency of 133 MHz, achieved via its internal PLL clock generator accepting a 1–20 MHz external reference clock. This frequency applies to the SH-3E CPU core and determines instruction execution rate, peripheral timing budgets, and cache access speed. The R8A77210C133BAV datasheet specifies this value under recommended operating conditions with 1.5 V core supply and 3.3 V I/O supply.

Does the R8A77210C133BAV include an integrated memory management unit (MMU)?

Yes, the R8A77210C133BAV includes a full-featured MMU supporting virtual memory addressing with a 64-entry Translation Lookaside Buffer (TLB). This enables use with memory-protected operating systems such as embedded Linux or safety-certified RTOS kernels. The MMU is documented in Section 4 of the R01UH0083EJ0400 Hardware Manual and is functionally identical across the SH7721 Group, including the R8A77210C133BAV.

Which package type is used for the R8A77210C133BAV?

The R8A77210C133BAV uses a 256-pin Low Profile Quad Flat Package (LQFP) with 28 mm × 28 mm body size and 0.4 mm lead pitch. This package is explicitly confirmed in Renesas documentation R01UH0083EJ0400 Section 1.3.1 and is shared across the SH7721 Group, including both R8A77210 and R8A77211 variants. Thermal pad exposure is included for enhanced heat dissipation.

What peripheral interfaces are integrated into the R8A77210C133BAV?

The R8A77210C133BAV integrates SCIF (four channels), SDHI (SD/MMC host interface), CMT (Compare Match Timer), TPU (Timer Pulse Unit with eight channels), DMAC (8-channel Direct Memory Access Controller), INTC (128-vector Interrupt Controller), and PFC (Pin Function Controller). These are detailed in Sections 1.2 and 6–11 of the R01UH0083EJ0400 Hardware Manual and are fully functional in the R8A77210C133BAV configuration.

Is the R8A77210C133BAV pin-compatible with other SH7721 Group devices?

Yes, the R8A77210C133BAV is pin-compatible with the R8A77211 within the SH7721 Group, sharing identical LQFP-256 pinout, power sequencing, and peripheral signal mapping. Differences between R8A77210 and R8A77211 are limited to internal configuration bits and minor feature enablement - no PCB changes are required when substituting R8A77210C133BAV for R8A77211 in existing designs.
