Product details
Overview
R7S910001CFP#AA0 from Renesas Electronics is a high-performance 32-bit Arm Cortex-R4 microcontroller targeting real-time industrial motion control systems, featuring a maximum operating frequency of 450 MHz, 498 DMIPS performance, on-chip FPU with single/double-precision support, 8 KB instruction and 8 KB data caches (both with ECC), and TCM memory (512 KB ATCM + 32 KB BTCM, ECC-protected).
For engineers reviewing the R7S910001CFP#AA0 datasheet, R7S910001CFP#AA0 pinout, R7S910001CFP#AA0 application, or R7S910001CFP#AA0 equivalent, this device serves as a deterministic, safety-aware MCU for EtherCAT slave implementations, servo drive control, and time-critical PLC edge nodes requiring sub-microsecond interrupt latency and hardware-accelerated encoder interface readiness.
Technical Context
The R7S910001CFP#AA0 implements a Harvard-architecture Arm Cortex-R4 core (r1p4) with 8-stage pipeline, MPU, and CoreSight debug via JTAG/SWD. It integrates dual DMAC units (16 channels each), event link controller (ELC) for CPU-sleep module chaining, and dedicated timer subsystems (TPUa, MTU3a, GPTa) supporting PWM generation, input capture, and A/D trigger synchronization.
Its peripheral set includes one Ethernet MAC (10/100BASE-TX, MII/RMII), two CAN 2.0B channels (1 Mbps), five SCIFA UARTs with 16-byte FIFOs, two I²C interfaces (400 kbps), four RSPI channels, SPIBSC for quad-SPI flash, and a 12-bit dual-unit A/D converter (8+16 channels, 0.483 µs/unit0 conversion time) with self-diagnosis and analog disconnection detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-R4 (r1p4), 450 MHz max - enables deterministic real-time execution with 747 DMIPS and low-latency interrupt response. |
| FPU Support | Single/double-precision IEEE 754 - accelerates motor control algorithms (FOC, PID) without software emulation overhead. |
| Memory Protection | MPU + ECC on TCM/cache - ensures memory integrity and prevents unintended code/data corruption in safety-critical operation. |
| On-chip SRAM | None (0 MB extended SRAM) - relies on external memory via 32-bit bus interface; no integrated 1 MB SRAM variant. |
| Package & Pins | 176-pin HLFQFP (20 × 20 mm, 0.4 mm pitch), 97 I/O pins - compact footprint suitable for space-constrained servo drive PCBs. |
| Operating Temp | Junction temperature −40°C to +125°C - qualified for under-hood industrial motor control environments with thermal stress. |
| Power Supply | DVDD = 1.14–1.26 V; VCCQ33 = 3.0–3.6 V - dual-rail design separates core logic and I/O domains for noise isolation and EMI resilience. |
Pinout & Package
Package: PLQP0176LD-A, 176-pin plastic LQFP (20 mm × 20 mm, 0.4 mm pitch), lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, DVDD | Core power supply | 1.14–1.26 V input for Cortex-R4 core and internal logic; requires local decoupling near pins. |
| VCCQ33, AVCC0/1 | I/O and analog power | 3.0–3.6 V supply for GPIO, ADC reference, and digital I/O; separate analog domain for S12ADCa stability. |
| RES#, NMI | Reset and non-maskable interrupt | Active-low asynchronous reset pin; NMI supports critical fault handling independent of interrupt controller state. |
| ETH0_TXD[3:0], ETH0_RXD[3:0] | Ethernet MAC physical interface | MII-mode signals for 10/100BASE-TX; requires impedance-controlled routing and PHY termination. |
| CAN0_TX, CAN0_RX | CAN 2.0B transceiver interface | Differential pair for first CAN channel; compatible with ISO 11898-1 compliant transceivers (e.g., TJA1051). |
| MTU3A_TIOA0–TIOA8 | PWM/timer output capture | 28 dedicated pulse I/O lines across 9 MTU3a channels - supports 3-phase inverter gate drive with dead-time insertion. |
| AN000–AN007 | Analog inputs (unit 0) | 8-channel 12-bit A/D converter input; includes sample-and-hold and disconnection detection for current sensing. |
| CLKIN, CLKOUT | External clock interface | 25 MHz crystal/resonator input; CLKOUT provides buffered system clock for trace/debug or peripheral sync. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware Event Link Controller (ELC) | Enables inter-module triggering without CPU intervention - allows timer-triggered ADC sampling while Cortex-R4 sleeps, reducing active power by >40% in idle cycles. |
| Dual DMAC Units (32 channels) | Offloads data movement from CPU - supports concurrent Ethernet packet buffering, CAN message queuing, and SPI flash streaming without interrupt overhead. |
| Integrated Safety Functions | CRC calculator, IWDTa, register write protection, and error control module (ECM) - meets IEC 61508 SIL2 requirements for functional safety without external monitors. |
| Multi-Function Pin Controller (MPC) | Permits flexible peripheral pin assignment - simplifies PCB layout reuse across RZ/T1 variants and reduces layer count in multi-protocol servo designs. |
| Real-Time Timer Subsystem | TPUa (12 ch), MTU3a (9 ch), GPTa (4 ch) with synchronized PWM and phase-counting - delivers precise 3-phase motor commutation timing with <100 ns jitter. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7S910002CBG | 320-pin FBGA package, same 450 MHz Cortex-R4 core but adds optional EtherCAT slave controller (ECATC) and supports 32-bit external bus. | Required for dual-port EtherCAT slave designs or when >97 I/O pins needed; not pin-compatible with R7S910001CFP#AA0. | Select when EtherCAT slave functionality is mandatory and PCB redesign for FBGA is acceptable. |
| R7S910006CBG | Same 320-pin FBGA package as R7S910002CBG but includes 1 MB on-chip extended SRAM with ECC - eliminates need for external SRAM in buffer-intensive applications. | Suitable for high-throughput EtherCAT frame processing or multi-axis motion buffering where external memory latency is unacceptable. | Choose when deterministic memory access >100 MB/s is required and 176-pin QFP footprint is not constrained. |
Compared with R7S910001CFP#AA0, R7S910002CBG adds EtherCAT slave capability at the cost of larger package and layout change, while R7S910006CBG trades pin count for integrated SRAM - both require PCB redesign but offer higher integration for next-generation servo nodes.

FAQ
What is the maximum operating frequency of the R7S910001CFP#AA0?
The R7S910001CFP#AA0 operates at a maximum frequency of 450 MHz. This is confirmed in Table 1.3 of the R01DS0228EJ0200 datasheet, which lists R7S910001CFP as a 176-pin device with 450 MHz capability. The part does not support 600 MHz operation - that rating applies only to select 320-pin variants like R7S910007CBG.
Does the R7S910001CFP#AA0 include an integrated EtherCAT slave controller?
No, the R7S910001CFP#AA0 does not include an integrated EtherCAT slave controller. As stated in Table 1.2 and Table 1.3 of the datasheet, EtherCAT support is marked "Not supported" for all 176-pin variants including R7S910001CFP. Only 320-pin packages (e.g., R7S910002CBG) list EtherCAT as optional.
How much on-chip extended SRAM does the R7S910001CFP#AA0 have?
The R7S910001CFP#AA0 has zero bytes of on-chip extended SRAM. Table 1.3 explicitly states "Not supported" under the "On-Chip Extended SRAM Capacity" column for R7S910001CFP. In contrast, R7S910006xxx variants provide 1 MB with ECC - a key differentiator for memory-intensive real-time tasks.
What debug interfaces are supported by the R7S910001CFP#AA0?
The R7S910001CFP#AA0 supports Arm CoreSight debugging via JTAG and SWD interfaces, as specified in the "Debugging interface" section on page 8 of the datasheet. Trace functionality is available through the SWV interface, enabling real-time instruction and data trace without halting CPU execution during development.
Is the R7S910001CFP#AA0 qualified for automotive applications?
No, the R7S910001CFP#AA0 is not AEC-Q100 qualified. Its operating temperature range is specified as Tj = −40°C to +125°C for industrial use, and the datasheet makes no mention of automotive qualification. Renesas offers separate R-Car and RH850 families for automotive-grade applications.
