It delivers 31 DMIPS at 24 MHz, supports 12-channel 8/10-bit ADC, dual comparators, RTC2 with calendar, and real-time LCD driving for battery-powered instrumentation.
For engineers reviewing the R5F10WMDGFB#30 datasheet, R5F10WMDGFB#30 pinout, R5F10WMDGFB#30 application, or R5F10WMDGFB#30 equivalent, this page provides verified electrical specs, validated 80-pin LFQFP terminal mapping, confirmed industrial-grade (−40°C to +105°C) operation, and direct alternatives for LCD-based embedded control designs requiring true low power (0.61 μA RTC+LVD mode).
Technical Context
The R5F10WMDGFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.04167 µs (24 MHz HS oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.
It integrates a dedicated LCD controller/driver supporting up to 51 segment × 8 common outputs using internal voltage boosting, capacitor split, or external resistor division methods - all selectable in firmware. The device includes four DMA channels, a 16-bit timer KB20 for PWM, and hardware BCD correction for numeric display handling.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F10WMDGFB#30?
The R5F10WMDGFB#30 operates up to 24 MHz using its high-speed on-chip oscillator, achieving 31 DMIPS performance. At this frequency, typical active current is 71 µA per MHz under VDD = 1.8–5.5 V. In STOP mode with RTC2 and LVD enabled, it draws just 0.61 µA-verified across the full −40°C to +105°C industrial temperature range.
Does the R5F10WMDGFB#30 support hardware LCD bias generation without external components?
Yes, the R5F10WMDGFB#30 includes an integrated LCD controller/driver capable of generating required bias voltages internally via voltage boosting, capacitor split, or external resistor division-configurable in firmware. No external charge pump or bias IC is needed for standard 3–5 V LCD modules.
How many UART interfaces does the R5F10WMDGFB#30 provide, and which support LIN bus?
The R5F10WMDGFB#30 provides three UART interfaces: UART0, UART1, and UART2. UART1 is explicitly LIN-bus compliant per ISO 14229 and supports automatic LIN header detection, sync field processing, and checksum validation-enabling direct integration into automotive body electronics networks.
Can the R5F10WMDGFB#30 perform background data flash writes while executing application code?
Yes, the R5F10WMDGFB#30 supports Background Operation (BGO) for data flash memory. While rewriting 4 KB of data flash, the CPU can continue executing instructions from code flash-enabling seamless firmware updates, parameter logging, or calibration storage without system interruption.
What is the function of the REMOOUT pin on the R5F10WMDGFB#30, and how is it configured?
The REMOOUT pin (P30) on the R5F10WMDGFB#30 generates carrier-wave output for infrared remote control transmission. It is driven by Timer Array Unit channel 3 (TAU0 ch3) and supports programmable carrier frequencies (e.g., 38 kHz) and modulation depth-configured via TMR03 register settings and enabled through the REMOEN bit in the REMOCTL register.
