Product details
Overview
R7S910020CBG#AC0 from Renesas Electronics is a high-performance 32-bit Arm Cortex-R4 real-time MCU operating at up to 450 MHz (747 DMIPS), featuring on-chip FPU, 8 KB instruction/data caches with ECC, 512 KB ATCM + 32 KB BTCM with ECC, and integrated safety functions including CRC, IWDTa, and error control module (ECM). It targets industrial motion control systems requiring deterministic low-latency response.
For engineers reviewing the R7S910020CBG#AC0 datasheet, R7S910020CBG#AC0 pinout, R7S910020CBG#AC0 application, or R7S910020CBG#AC0 equivalent, key selection criteria include its 112-pin FBGA package (PLBG0112KA-A), dual 12-bit A/D converters (8+8 channels), TPUa timer unit for PWM generation, MDIO slave interface for CFP MSA optical transceivers, and -40°C to +110°C junction temperature rating.
Technical Context
The R7S910020CBG#AC0 implements Arm v7-R architecture with Harvard memory system, 8-stage pipeline, and MPU support. Its real-time capability is reinforced by event link controller (ELC) enabling peripheral-triggered operation without CPU intervention-even during sleep-and vector interrupt controller handling 96 peripheral + 8 external interrupt sources.
It integrates dual DMAC units (16 channels each), SPIBSC for quad-I/O flash memory, RSPIa with 128-bit buffers, and SCIFA with 16-byte FIFOs per channel. Clock generation supports 25 MHz crystal input, PLL-derived 450 MHz CPU clock, and LOCO-based 240 kHz low-speed oscillator for independent watchdog timing.

FAQ
What is the maximum operating frequency and DMIPS rating of the R7S910020CBG#AC0?
The R7S910020CBG#AC0 operates at a maximum CPU frequency of 450 MHz and delivers 747 DMIPS performance. This is measured under standard conditions using the Dhrystone 2.1 benchmark at full speed, confirming its capability for demanding real-time control tasks such as servo motor commutation and multi-axis interpolation within the R7S910020CBG#AC0's architecture.
Does the R7S910020CBG#AC0 include on-chip extended SRAM?
No, the R7S910020CBG#AC0 does not include on-chip extended SRAM. As confirmed in Table 1.3 of the datasheet, this variant has "Not supported" for on-chip extended SRAM capacity. It relies solely on 512 KB ATCM and 32 KB BTCM with ECC for high-speed code and data storage, distinguishing it from the R7S910021CBG#AC0 which adds 1 Mbyte of extended SRAM.
What safety features are integrated into the R7S910020CBG#AC0?
The R7S910020CBG#AC0 integrates register write protection, input clock oscillation stop detection, CRC calculator (supporting 32/16/8-bit polynomials), independent watchdog timer (IWDTa), A/D self-diagnosis, and a dual-redundant error control module (ECM). These features collectively support IEC 61508 SIL2 compliance and are documented in Sections 1.1 and 1.4 of the R01DS0253EJ0170 datasheet for the R7S910020CBG#AC0.
Which communication interfaces does the R7S910020CBG#AC0 support for optical transceiver management?
The R7S910020CBG#AC0 supports MDIO slave interface (MDC/MDIO pins, up to 4 MHz) compliant with CFP MSA specifications for optical transceiver module control. It does not include MDIO master functionality - that is reserved for variants like R7S910022CBG#AC0. The R7S910020CBG#AC0 uses this slave interface to monitor and configure optical modules in industrial backplane applications.
What is the operating temperature range and package type of the R7S910020CBG#AC0?
The R7S910020CBG#AC0 is rated for junction temperature (Tj) from -40°C to +110°C and is housed in a 112-pin FBGA package (PLBG0112KA-A) with 6 mm × 6 mm footprint and 0.5 mm pitch. This package and temperature grade are explicitly specified in Table 1.1 and Figure 1.2 of the R01DS0253EJ0170 datasheet for the R7S910020CBG#AC0.
