For engineers reviewing the R9A07G075M28GBG#AC0 datasheet, R9A07G075M28GBG#AC0 pinout, R9A07G075M28GBG#AC0 application, or R9A07G075M28GBG#AC0 equivalent, this page delivers verified specifications, package mapping, safety-certified peripheral integration, and direct alternative part comparisons for motion control, robotics, and industrial PLC design.

Technical Context

The R9A07G075M28GBG#AC0 implements two Arm Cortex-R52 cores (r1p2) in lock-step–independent configuration-not DCLS-with separate TCM (CPU0: 512 KB ATCM + 64 KB BTCM), ECC-protected instruction/data caches (16 KB/32 KB per core), and Arm v8-R architecture supporting Thumb-2, FPU, NEON, and CoreSight debug. It targets deterministic real-time execution in safety-critical motion systems.

Its subsystem-level integration includes an EtherCAT slave controller (Beckhoff IP core, MII interface), 3-port Ethernet switch with TSN support (PRP, frame preemption, TDMA), dual xSPI controllers compliant with JESD251 (up to 64 MB per CS, XiP mode), and dual DSMIF units supporting up to six external ΔΣ modulators for high-resolution current sensing.

FAQ

What is the maximum operating frequency of the R9A07G075M28GBG#AC0 CPU cores?

The R9A07G075M28GBG#AC0 supports dual Arm Cortex-R52 cores operating at up to 800 MHz when paired with a 200 MHz system clock. This frequency is confirmed in Table 1.1 of the R01DS0383EJ0130 datasheet and enables hard real-time execution of complex motion control algorithms with sub-microsecond interrupt latency. The R9A07G075M28GBG#AC0 achieves this performance while maintaining ECC protection on TCM and caches.

Does the R9A07G075M28GBG#AC0 include an integrated EtherCAT slave controller?

Yes, the R9A07G075M28GBG#AC0 integrates a Beckhoff Automation–licensed EtherCAT slave controller (ESC) with three MII ports, as specified in Table 1.8 and confirmed in the Product Lineup (Table 1.16). This ESC IP core is fully compliant with EtherCAT protocol standards and supports distributed clock synchronization essential for multi-axis coordinated motion. It is enabled in all 320-pin FBGA variants including R9A07G075M28GBG#AC0.

What is the on-chip SRAM capacity and ECC implementation for the R9A07G075M28GBG#AC0?

The R9A07G075M28GBG#AC0 includes 2.0 MB of on-chip system SRAM with SEC-DED (single error correction/double error detection) ECC, as documented in Table 1.2 and Section 1.3. This memory is partitioned into four 512 KB banks, each protected independently, and operates at 150/200 MHz. The ECC implementation supports error injection for validation and is mandatory for functional safety certification in IEC 61508 applications.

Which ΔΣ modulator interfaces are supported by the R9A07G075M28GBG#AC0?

The R9A07G075M28GBG#AC0 supports up to six external ΔΣ modulators via two DSMIF units (DSMIF0 and DSMIF1), each with three configurable channels (U/V/W or U/V), as defined in Table 1.10 and Figure 1.1. Each DSMIF unit supports selectable Sinc1–Sinc3 digital filters and direct error signaling to POE3/POEG for fast fault response-critical for high-fidelity motor current sensing in servo applications.

Is the R9A07G075M28GBG#AC0 qualified for extended temperature operation?

Yes, the R9A07G075M28GBG#AC0 is rated for junction temperature operation from −40°C to +125°C, as explicitly stated in Table 1.14 and confirmed across all electrical characteristics tables in the R01DS0383EJ0130 datasheet. This qualification enables deployment in harsh industrial environments such as motor drive cabinets and robotic joints without thermal derating or additional cooling infrastructure.
