Renesas R7S910036CBA#BC0

Overview

R7S910036CBA#BC0 from Renesas Electronics is a high-performance real-time MCU featuring an Arm Cortex-R4 processor operating at 450 MHz, integrated 1 Mbyte on-chip extended SRAM with ECC, dual Ethernet MAC (1 port standard + optional switch for 2-port operation), dual CAN 2.0B interfaces, and industrial-grade temperature range (−40°C to +125°C). It targets deterministic motion control systems requiring tight timing, safety-critical I/O handling, and EtherCAT slave functionality.

For engineers reviewing the R7S910036CBA#BC0 datasheet, R7S910036CBA#BC0 pinout, R7S910036CBA#BC0 application, or R7S910036CBA#BC0 equivalent, key selection considerations include its 320-pin FBGA package (PRBG0320GB-A), 450 MHz Cortex-R4 core with FPU and TCM, dual CAN channels supporting 1 Mbps, Ethernet MAC with MII/RMII, and support for industrial encoder protocols including EnDat 2.2 and BiSS-C via optional interface.

Technical Context

The R7S910036CBA#BC0 implements a dual-core architecture with a primary Arm Cortex-R4 core (r1p4) running at 450 MHz (747 DMIPS), Harvard pipeline, 8 KB instruction/data caches with ECC, and 512 KB ATCM + 32 KB BTCM with ECC. It lacks the optional R-IN engine (Cortex-M3) and EtherCAT slave controller per Table 1.3, distinguishing it from R7S910011xx and R7S910013xx variants.

Its peripheral set includes two CAN modules compliant with ISO 11898-1 (1 Mbps max), one Ethernet MAC supporting IEEE 802.3, 10/100BASE-TX, full/half duplex, and MII/RMII; five SCIFA channels with 16-byte FIFOs; four RSPIa channels; and two RIICa interfaces up to 400 kbps - all configured for deterministic industrial communication without EtherCAT or encoder interface hardware.

FAQ

What is the maximum operating frequency of the R7S910036CBA#BC0?

The R7S910036CBA#BC0 operates at a maximum CPU frequency of 450 MHz, delivering 747 DMIPS performance. This frequency is fixed for this specific part number, as confirmed in Table 1.3 of the R01DS0228EJ0200 datasheet. The R7S910036CBA#BC0 does not support 300 MHz or 600 MHz configurations - those are assigned to other members of the RZ/T1 family such as R7S910001CFP and R7S910007CBA. The 450 MHz rating applies to the Arm Cortex-R4 core only.

Does the R7S910036CBA#BC0 include EtherCAT slave functionality?

No, the R7S910036CBA#BC0 does not include EtherCAT slave controller (ECATC) hardware. Per Table 1.3 in the R01DS0228EJ0200 datasheet, EtherCAT is marked as "Not supported" for this part number. EtherCAT capability is only present in variants with "11", "13", or "15" in the fourth and fifth digits (e.g., R7S910011CBA). The R7S910036CBA#BC0 retains the standard Ethernet MAC (ETHERC) but lacks the Beckhoff-designed ECATC IP core.

What package type and pin count does the R7S910036CBA#BC0 use?

The R7S910036CBA#BC0 uses a 320-pin Fine-Pitch Ball Grid Array (FBGA) package designated PRBG0320GB-A, measuring 17 mm × 17 mm with 0.8 mm ball pitch. This matches the mechanical and thermal specifications listed on page 8 of the R01DS0228EJ0200 datasheet. It is functionally and physically identical to the PRBG0320GA-A and PLBG0320GB-A packages used by other 320-pin RZ/T1 devices, ensuring board-level compatibility across the family.

Is the R7S910036CBA#BC0 equipped with on-chip extended SRAM, and how much?

Yes, the R7S910036CBA#BC0 integrates 1 Mbyte of on-chip extended SRAM with SEC-DED (single-error correction, double-error detection) ECC. This is explicitly listed in Table 1.3 of the R01DS0228EJ0200 datasheet under "On-Chip Extended SRAM Capacity" for part number R7S910036CBA. The SRAM operates at 150 MHz and is accessible without wait states, making it suitable for real-time control buffers, firmware stacks, and safety-critical data logging.

Which industrial communication interfaces are supported by the R7S910036CBA#BC0?

The R7S910036CBA#BC0 supports dual CAN 2.0B interfaces (ISO 11898-1, up to 1 Mbps), one Ethernet MAC (IEEE 802.3, 10/100BASE-TX, MII/RMII), five SCIFA UARTs with 16-byte FIFOs, four RSPIa SPI controllers, two RIICa I²C interfaces (up to 400 kbps), and one USB 2.0 HS host/function channel. It does not include EtherCAT, encoder interfaces (EnDat/BiSS), or the R-IN engine (Cortex-M3), as confirmed in Table 1.2 and Table 1.3 of the official datasheet.
