Product details
Overview
R5F56108WNBG#G0 from Renesas is a 32-bit RX610 Group MCU featuring a 100 MHz RX CPU core with single-cycle instruction execution, integrated 2 Mbyte flash, 128 Kbyte RAM, 32 Kbyte data flash, 10-bit A/D and D/A converters, and dual I²C interfaces - deployed in industrial HMI panels and office automation controllers requiring deterministic real-time response.
For engineers reviewing the R5F56108WNBG#G0 datasheet, R5F56108WNBG#G0 pinout, R5F56108WNBG#G0 application, or R5F56108WNBG#G0 equivalent, this page delivers verified package mapping (176-pin LFBGA), validated peripheral register-level functions (TPU, SCI, RIIC), confirmed operating voltage (3.0–3.6 V), and direct alternative part comparisons for migration or second-sourcing.
Technical Context
The R5F56108WNBG#G0 implements a 32-bit RX CPU with IEEE 754-compliant single-precision FPU, 32×32→64-bit multiplier, and 32/32→32-bit divider - enabling floating-point control loops without external coprocessors. Its memory subsystem includes on-chip 2 Mbyte flash with three programming modes (SCI boot, user program, user boot) and 32 Kbyte data flash for parameter storage.
Peripheral timing is decoupled across three clocks: system clock (ICLK, 8–100 MHz for CPU/RAM), peripheral clock (PCLK, 8–50 MHz for timers/ADC/SCI), and external bus clock (BCLK, 8–25 MHz). The device supports eight interrupt priority levels, 116 peripheral interrupts, and four power-down modes including deep software standby.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F56108VNFP | Same RX610 core, identical memory and peripheral specs, but 144-pin LQFP package (PLQP0144KA-A) instead of 176-pin LFBGA. | LQFP simplifies prototyping and rework but limits I/O count (117 vs. 140 pins) and high-speed signal integrity for BCLK/external bus. | Select when board space permits larger footprint and manual soldering is preferred over BGA reflow. |
| R5F56107WNBG | Same 176-pin LFBGA package and peripheral set, but reduced 1.5 Mbyte flash (vs. 2 Mbyte) and same 128 Kbyte RAM/data flash. | Lower flash capacity restricts firmware size for feature-rich applications like encrypted OTA updates or multi-language UI support. | Select when application firmware fits within 1.5 Mbyte and cost sensitivity outweighs future scalability needs. |
Compared with R5F56108WNBG#G0, R5F56108VNFP trades BGA density for LQFP accessibility while retaining full functionality, whereas R5F56107WNBG sacrifices 512 Kbyte flash for lower unit cost - both require no firmware changes but differ in layout compatibility and long-term feature headroom.

FAQ
What is the maximum operating frequency and core architecture of the R5F56108WNBG#G0?
The R5F56108WNBG#G0 operates at a maximum frequency of 100 MHz using the 32-bit RX CPU core. It executes most instructions in a single clock cycle and includes a single-precision floating-point unit compliant with IEEE 754. This architecture enables deterministic real-time performance for control-intensive applications without external math acceleration.
Does the R5F56108WNBG#G0 support external memory expansion, and what interface options are available?
Yes, the R5F56108WNBG#G0 supports external memory expansion via an 8/16-bit parallel external bus with eight independently configurable chip-select areas (CS0–CS7), each supporting up to 16 Mbyte addressing. Signals include WR#, RD#, BCLK, WAIT#, and address/data lines - enabling direct connection to NOR flash, SRAM, or FPGA peripherals without glue logic.
How many analog-to-digital and digital-to-analog converter channels does the R5F56108WNBG#G0 integrate?
The R5F56108WNBG#G0 integrates four independent 10-bit A/D converter units (totaling 16 input channels) with 1.0 µs conversion time at 50 MHz PCLK, plus two 10-bit D/A converter channels (DA0 and DA1) with output range from 0 V to VREFH. These are used for sensor interfacing, actuator control, and calibration reference generation.
What power management features does the R5F56108WNBG#G0 offer for low-power industrial applications?
The R5F56108WNBG#G0 provides four power-down modes: sleep mode, all-module clock stop mode, software standby mode, and deep software standby mode. In deep software standby, current drops below 10 µA while retaining RAM content and wake-up capability via RTC or external interrupt - ideal for battery-backed sensor nodes or intermittently active control modules.
Is the R5F56108WNBG#G0 pin-compatible with other RX610 Group MCUs, and what package does it use?
The R5F56108WNBG#G0 uses the 176-pin LFBGA package (PLBG0176GA-A) and shares identical pin functions with other WNBG-suffixed RX610 variants (e.g., R5F56107WNBG, R5F56106WNBG). However, it is not pin-compatible with VNFP-suffixed LQFP variants due to differing pin counts and physical layout - PCB redesign is required for package substitution.
