R5F56216BDFB#V0 - 100MHz RX MCU 256KB Flash 144-LFQFP | Renesas
MPN: R5F56216BDFB#V0 ✓ Hoạt độngR5F56216BDFB#V0 Tóm tắt
A 32-bit MCU is a microprocessor in which the data path, registers, and ALU are 32 bits wide, allowing a single instruction to handle larger integer and floating-point values than an 8- or 16-bit controller. The RX core sits in the broader taxonomy as 32-bit microcontroller -> embedded MCU -> semiconductor -> integrated circuit. Combining high CPU throughput, large SRAM, and integrated connectivity, the RX621 family targets applications that previously required an external host processor plus discrete communication ICs.
Key features include 100 MHz core with 165 DMIPS, hardware single-precision FPU, 256 KB Flash / 64 KB SRAM, 10 KB data Flash, Ethernet MAC, USB 2.0 FS Host/Function, CAN, and up to 123 I/O pins. The 12-bit ADC achieves up to 1 Msps with three sample-and-hold units, while the EXDMAC and DTC subsystems handle data movement without CPU intervention.
Typical applications include industrial Ethernet gateways, factory automation controllers, USB-connected human-machine interfaces (HMIs), building-automation concentrators, and CAN-connected sensor hubs. The wide peripheral mix and large SRAM also make the part suitable for point-of-sale terminals and small-format IoT edge nodes.
When designing with the R5F56216BDFB#V0, allocate decoupling per the hardware manual, observe the 0.5 mm LQFP pitch soldering profile (JEDEC J-STD-020 MSL classification applies), and verify the pin assignments against the device's full 144-pin LQFP variant symbol. The part is RoHS-compliant per Renesas product information.
This page synthesizes distributor pricing, drop-in same-package alternatives from the RX621 family, and practical design notes that complement the official Renesas hardware manual rather than repeating it verbatim.

Ứng dụng tiêu biểu
R5F56216BDFB#V0 phù hợp cho 6 Áp dụngs: Industrial Ethernet Gateway, USB Human-Machine Interface (HMI), Building Automation Controller, CAN-Connected Sensor Hub, Point-of-Sale (POS) Terminal, Industrial IoT Edge Node.
Industrial Ethernet Gateway
The R5F56216BDFB#V0's integrated 10/100 Ethernet MAC and EDMAC controller pair with an external PHY to realize deterministic TCP/IP communication in factory-floor gateways. At 100 MHz and 165 DMIPS, the RX v1 core can sustain multi-protocol bridging between Modbus TCP, EtherNet/IP and PROFINET with room for application-layer processing. The 64 KB SRAM allows full socket buffering without dropping packets under burst load.
Được đề xuất
USB Human-Machine Interface (HMI)
The integrated USB 2.0 Full-Speed Host/Function controller eliminates external glue logic in USB-connected HMIs. The 256 KB Flash runs USB HID, CDC, or vendor-class stacks with display-driver code, while the 12-bit ADC reads analog control inputs at up to 1 Msps. The 0.5 mm-pitch LFQFP package is suitable for hand-solderable prototypes and short-cycle industrial designs.
Được đề xuất
Building Automation Controller
The R5F56216BDFB#V0 supports multiple UARTs, I2C buses and CAN 2.0B simultaneously, allowing a single MCU to interface with HVAC sensors, lighting controls, and security subsystems. The deep Sleep and Standby modes combined with the 10 KB data Flash for non-volatile parameter storage suit battery-backed building controllers. Integrated Ethernet provides BACnet/IP or KNX/IP uplink connectivity.
Được đề xuất
CAN-Connected Sensor Hub
The R5F56216BDFB#V0's hardware CAN 2.0B controller with 32 mailbox slots enables robust CANopen and DeviceNet implementations. The 123 I/O pins allow direct connection to digital and analog sensor arrays, while the EXDMAC off-loads bulk ADC reads into SRAM without CPU intervention. The 2.7 V to 3.6 V supply range is compatible with industrial 3.3 V CAN transceivers.
Được đề xuất
Point-of-Sale (POS) Terminal
The R5F56216BDFB#V0 balances security and connectivity needed in POS terminals. The hardware FPU accelerates financial cryptography primitives (AES, SHA, RSA partial) while the Ethernet MAC supports IP-based payment authorizers and the USB host connects to peripherals such as NFC readers. The 256 KB Flash accommodates boot, payment, and TLS libraries within a single image.
Được đề xuất
Industrial IoT Edge Node
The R5F56216BDFB#V0 fits edge nodes that aggregate sensor data over RS-485 or CAN and forward via Ethernet or USB. The low-power Sleep modes (down to single-digit microamp range per the RX621 hardware manual) keep idle consumption low. The 64 KB SRAM handles TLS session buffers and MQTT message queuing without external memory, keeping the BOM compact.

Ghi chú thiết kế
Place a 0.1 uF X7R decoupling capacitor as close as possible to every VCC pin and to the AVCC pin; add a single 10 uF bulk cap on each power domain. The 0.5 mm pitch LFQFP is hand-rework-friendly but requires careful reflow profile control (JEDEC J-STD-020); verify the part MSL on the label before floor-life exposure.
The R5F56216BDFB#V0 requires a 2.7 V to 3.6 V single supply with VCL and USB_PVCC pins both decoupled. Recommended: use a 3.3 V LDO with at least 200 mA headroom (typical Ethernet and USB current consumption). For USB applications, route USBDP/USBDM as 90-ohm differential pair.
Estimated: at 100 MHz CPU and full peripheral block operation, the MCU consumes around 100 mA during active mode. Sleep modes drop to single-digit mA. The MODE pin must be pulled correctly during reset for boot mode selection; an open or floating MODE pin can prevent code execution. The Ethernet PHY needs an external 50 MHz reference unless sourced from the MCU's dedicated Ethernet clock output pin.
