Overview
R5F10WMGAFB#30 from Renesas is an 80-pin RL78/L13 16-bit microcontroller with integrated LCD controller/driver, 128 KB flash, 6 KB RAM, and 4 KB data flash. It operates from 1.6 V to 5.5 V, delivers 31 DMIPS at 24 MHz, and achieves ultra-low power consumption (71 μA/MHz active, 0.61 μA in RTC+LVD STOP mode), targeting battery-powered LCD-based industrial instrumentation.
For engineers reviewing the R5F10WMGAFB#30 datasheet, R5F10WMGAFB#30 pinout, R5F10WMGAFB#30 application, or R5F10WMGAFB#30 equivalent, this page provides verified technical context, validated pin functions, real-world use cases for LCD metering and sensor interfaces, and confirmed alternative parts with documented functional trade-offs.
Technical Context
The RL78 CPU core uses a CISC architecture with 3-stage pipeline and supports selectable instruction execution times from 0.04167 µs (24 MHz high-speed on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). It features a unified 1 MB address space and four banks of 8-bit general-purpose registers.
Power management includes HALT, STOP, and SNOOZE modes, plus on-chip POR and 14-level LVD with interrupt/reset selection. The peripheral set integrates 12-channel 8/10-bit ADC, dual comparators, 8-channel 16-bit timer array (TAU), real-time clock 2 with calendar and alarm, and 3 UART channels (including LIN support).

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F10WMGAFB#30?
The R5F10WMGAFB#30 achieves 24 MHz operation using its high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V supply. At this frequency, active current is specified at 71 μA/MHz (1.7 mA typical at 24 MHz, VDD = 3.0 V, TA = 25°C), making it suitable for high-performance yet battery-sensitive applications.
Does the R5F10WMGAFB#30 support hardware-based LIN bus communication?
Yes, the R5F10WMGAFB#30 supports LIN 2.2 protocol via UART2 channel with dedicated LINSEL pin and automatic sync-break detection. This enables direct connection to LIN transceivers without software bit-banging, reducing CPU load and improving timing reliability in automotive body electronics.
How many LCD segments and commons can the R5F10WMGAFB#30 drive simultaneously?
The R5F10WMGAFB#30 drives up to 51 segment signals and 4 common signals (or 47 segments with 8 commons) using its integrated LCD controller/driver. All segment and common outputs are configurable via register settings, and bias voltage generation is supported via internal boosting, capacitor-split, or external resistor-divider methods.
What debug and programming interfaces are available on the R5F10WMGAFB#30?
The R5F10WMGAFB#30 includes on-chip debug functionality accessible through TOOLRxD/TOOLTxD (P17/P00) and TOOL0 (P40) pins. It supports Renesas E2 emulator and E2 studio IDE for full-cycle development, including flash programming, real-time variable watch, and low-power mode validation without external debug probes.
Is the R5F10WMGAFB#30 pin-compatible with other RL78/L13 variants in the 80-pin package?
Yes, all RL78/L13 80-pin variants - including R5F10WMAx through R5F10WMGx - share identical pinouts and electrical characteristics. This allows hardware reuse across memory configurations (16–128 KB flash) and simplifies design scaling, provided firmware accounts for differing RAM and peripheral enablement.
