Product details
Overview
R7FS5D57A3A01CFP#BA1 from Renesas is a 120-MHz Arm Cortex-M4 microcontroller with FPU, 512-KB code flash, 384-KB SRAM, dual CAN, Ethernet MAC, USB 2.0 Full-Speed, SDHI ×2, QSPI, CTSU, and hardware crypto engine (SCE7), designed for industrial IoT gateways requiring real-time control, secure connectivity, and deterministic timing.
For engineers reviewing the R7FS5D57A3A01CFP#BA1 datasheet, R7FS5D57A3A01CFP#BA1 pinout, R7FS5D57A3A01CFP#BA1 application, or R7FS5D57A3A01CFP#BA1 equivalent, this page delivers verified specifications, package mapping to 100-pin LQFP, validated I/O count (75), confirmed safety features (ECC, IWDT, CAC), and two field-validated alternative parts with documented functional and packaging differences.
Technical Context
This MCU implements an Armv7E-M architecture with DSP extensions and single-precision FPU, supporting deterministic real-time execution at 120 MHz with zero-wait-state 40-MHz flash access. It integrates dual independent watchdogs (WDT + IWDT), memory protection units (MPU), and ECC on 32 KB of SRAM for functional safety compliance in industrial environments.
The peripheral set includes Ethernet MAC (ETHERC) linked to EDMAC for zero-CPU packet handling, dual SDHI controllers supporting SDXC/eMMC 4.51, and a dedicated Sampling Rate Converter (SRC) for audio preprocessing. Its CTSU supports up to 18 touch channels, and the PDC unit enables parallel image sensor data capture via DMAC/DTC to SRAM or external SDRAM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4 @ 120 MHz with FPU and DSP instruction set - enables floating-point math for motor control and signal processing without software emulation. |
| Memory | 512-KB code flash (40 MHz zero wait states), 32-KB data flash (125k erase/write cycles), 384-KB SRAM (32 KB with ECC) - balances firmware size, data logging durability, and real-time buffer space. |
| Connectivity | Ethernet MAC + EDMAC, USB 2.0 FS (on-chip transceiver), CAN ×2 (ISO 11898-1), SDHI ×2 (SDXC/eMMC 4.51), QSPI - supports wired industrial networking, local storage, and secure firmware updates. |
| Analog | ADC12 ×2 (13+9 ch, 12/10/8-bit selectable), DAC12 ×2, ACMPHS ×6, TSN - enables multi-sensor monitoring, analog actuator control, and die temperature compensation. |
| Security | SCE7 crypto engine: AES128/192/256, SHA256, RSA/ECC, TRNG, 128-bit unique ID - provides hardware-accelerated TLS stack offload and secure boot root-of-trust. |
| Package & Temp | 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch), -40°C to +105°C - suitable for convection-cooled industrial enclosures with PCB assembly compatibility. |
Pinout & Package
Package: 100-pin LQFP (PLQP0100KB-B), 14 mm × 14 mm, 0.5 mm pitch, RoHS-compliant Sn finish. Pin count: 75 I/O, 1 dedicated input, 76 pull-up resistors, 75 N-ch open-drain outputs, 14 5-V tolerant pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Digital power supply / ground | Primary 2.7–3.6 V domain; decoupling required per datasheet layout guidelines to maintain 120-MHz core stability. |
| VBATT | Backup power input | Supplies RTC, SOSC, and backup registers during main power loss - enables calendar retention and wake-on-event capability. |
| XTAL / EXTAL | Main crystal oscillator interface | Supports 8–24 MHz crystals for precise system clock generation; critical for Ethernet PHY synchronization and USB timing accuracy. |
| XCIN / XCOUT | Sub-clock oscillator interface | 32.768 kHz crystal connection for RTC calendar mode and low-power timer operation in Deep Software Standby. |
| RES | Reset input | Active-low asynchronous reset pin; must be held low ≥100 ns after power stabilization for reliable initialization. |
| MD | Mode selection | Configures boot source (SCI/USB vs. flash); level must be stable before release from reset to avoid undefined startup behavior. |
| TMS / TCK / TDO / SWDIO / SWCLK | JTAG/SWD debug interface | Enables full-core debugging, flash programming, and boundary scan; SWD pins support production programming with minimal footprint. |
| ETH_MDC / ETH_MDIO / ETH_TXD[3:0] / ETH_RXD[3:0] | Ethernet MAC physical layer interface | Direct connection to external PHY; requires impedance-controlled routing and proper termination per IEEE 802.3 for 10/100 Mbps operation. |
| USB_VBUS / USB_DP / USB_DM | USB 2.0 Full-Speed interface | On-chip transceiver eliminates external PHY; VBUS detection enables host/device role negotiation and enumeration control. |

Key Features
| Feature | Design Value |
|---|---|
| Memory Mirror Function (MMF) | Maps application load address in flash to link address in unused 23-bit memory space - simplifies firmware update by eliminating relocation requirements. |
| Event Link Controller (ELC) | Hardware routing of peripheral events (e.g., ADC conversion complete → GPT trigger) without CPU intervention - reduces latency and ISR overhead in real-time control loops. |
| Capacitive Touch Sensing Unit (CTSU) | 18-channel capacitive sensing with built-in noise rejection - enables robust touch HMI on metal-front panels without external ICs or shielding. |
| Parallel Data Capture (PDC) | Direct capture of parallel image sensor output into SRAM or SDRAM via DMAC/DTC - eliminates CPU polling for vision-based inspection systems. |
| Clock Frequency Accuracy Measurement (CAC) | Measures oscillator drift against reference clock and generates interrupt on deviation - validates timing integrity for safety-critical Ethernet or CAN FD applications. |
