Renesas R7S910025CBA#BC0

Overview

R7S910025CBA#BC0 from Renesas Electronics is a high-performance real-time MCU featuring an Arm Cortex-R4 processor (r1p4) operating at 450 MHz, integrated 1 Mbyte on-chip extended SRAM with ECC, dual Ethernet MAC support (1 port + optional switch), and dual CAN 2.0B interfaces - deployed in industrial motion control systems requiring deterministic low-latency response and functional safety compliance.

For engineers reviewing the R7S910025CBA#BC0 datasheet, R7S910025CBA#BC0 pinout, R7S910025CBA#BC0 application, or R7S910025CBA#BC0 equivalent, key selection criteria include its 450 MHz Cortex-R4 core with FPU, 1 Mbyte ECC-protected SRAM, EtherCAT slave controller readiness (optional), encoder interface capability (EnDat 2.2/BiSS-C), and -40°C to +125°C junction temperature rating for harsh environments.

Technical Context

The R7S910025CBA#BC0 implements a dual-core architecture with a primary 450 MHz Arm Cortex-R4 core (r1p4) supporting Thumb-2, Harvard pipeline, TCM (512 KB ATCM + 32 KB BTCM), and single/double-precision FPU - optimized for hard real-time control loops. It integrates a dedicated event link controller (ELC) enabling peripheral-triggered operation without CPU wake-up, critical for ultra-low-latency motor control timing.

Its peripheral set includes two independent CAN 2.0B controllers (1 Mbps), dual Ethernet MAC (IEEE 802.3, 10/100BASE-TX, MII/RMII), and a configurable ΔΣ interface supporting up to four external modulators - all synchronized via shared clock domains and ELC-triggered A/D conversion start signals from MTU3a/GPTa timers.

FAQ

What is the maximum operating frequency of the R7S910025CBA#BC0?

The R7S910025CBA#BC0 operates at a maximum CPU frequency of 450 MHz using its Arm Cortex-R4 core. This frequency is achieved with a 25 MHz external crystal input feeding the on-chip PLL. The device also supports fixed 150 MHz system clock and 75 MHz peripheral bus clock - all derived from the same PLL source to ensure phase coherence for real-time control timing.

Does the R7S910025CBA#BC0 include EtherCAT slave functionality?

The R7S910025CBA#BC0 includes the EtherCAT Slave Controller (ECATC) IP core as an optional feature - it is physically present and enabled in this part variant. The ECATC supports two ports and complies with EtherCAT protocol specifications, enabling direct integration into EtherCAT networks without external ASICs or FPGAs.

What encoder interface protocols does the R7S910025CBA#BC0 support?

The R7S910025CBA#BC0 supports EnDat 2.2, BiSS-C, FA-CODER, A-format, and HIPERFACE DSL encoder protocols via its two dedicated encoder interface channels. These are implemented as hardware-peripheral blocks with synchronous serial interfaces and ELC-triggered DMA readout - eliminating software overhead for high-speed position feedback acquisition.

How much on-chip SRAM does the R7S910025CBA#BC0 provide, and is it protected?

The R7S910025CBA#BC0 integrates 1 Mbyte of on-chip extended SRAM with full SEC-DED (single error correction/double error detection) ECC protection. This memory operates at 150 MHz and is accessible by both the Cortex-R4 core and DMA controllers - ensuring data integrity for safety-critical variables and real-time buffers in industrial applications.

What is the operating temperature range specified for the R7S910025CBA#BC0?

The R7S910025CBA#BC0 is rated for a junction temperature range of -40°C to +125°C. This specification is validated across the full 320-pin FBGA package (PRBG0320GB-A) and applies to all core and peripheral functions - confirming suitability for deployment in uncooled industrial enclosures, motor drive cabinets, and robotic joints exposed to ambient thermal stress.
