Product details
Overview
R5F10WMGGFB#30 from Renesas is an 80-pin LFQFP, industrial-grade RL78/L13 16-bit microcontroller with integrated LCD controller/driver, 128 KB flash, 8 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 display systems in industrial metering and HMI panels.
For engineers reviewing the R5F10WMGGFB#30 datasheet, R5F10WMGGFB#30 pinout, R5F10WMGGFB#30 application, or R5F10WMGGFB#30 equivalent, key selection considerations include its 51-segment/8-common LCD drive capability, 12-channel 8/10-bit ADC, dual comparators with internal reference, 3 UARTs (including LIN support), and industrial temperature range (−40°C to +105°C) with AEC-Q100 not claimed.
Technical Context
The R5F10WMGGFB#30 implements the RL78 CPU core - a CISC architecture with 3-stage pipeline and 1 MB address space - paired with a dedicated LCD controller supporting internal voltage boosting, capacitor-split, or external resistor division methods. Its timer subsystem includes eight 16-bit TAU channels, one 16-bit KB20 timer for PWM, a 12-bit interval timer, and RTC2 with calendar and alarm functions.
Power management integrates POR, LVD (14-level selectable), HALT/STOP/SNOOZE modes, and a low-power 15 kHz on-chip oscillator. Communication peripherals comprise three UARTs (one LIN-capable), two CSI interfaces (SPI-like), one I²C channel, and serial array unit support for simultaneous multi-protocol operation - all configurable via peripheral I/O redirection register (PIOR).

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10WMEGFB#30 | 48 KB flash, 2 KB RAM, same 80-pin LFQFP package and peripheral set | Lower memory footprint suits simpler HMI or sensor nodes without firmware updates or large data buffers | Select when application logic fits within 48 KB code and 2 KB RAM; retains identical pinout, LCD drive, and industrial temp rating |
| R5F10WLGGFB#30 | 64-pin LFQFP, 128 KB flash, 8 KB RAM, but only 36-segment/4-common LCD drive | Reduced LCD capability limits use to smaller displays; fewer GPIOs (49 vs. 65) constrain complex I/O expansion | Choose for space-constrained designs needing full 128 KB flash but not 51-segment LCD; saves board area with smaller 64-pin footprint |
Compared with R5F10WMEGFB#30, the R5F10WMGGFB#30 provides 2.7× more flash and 4× more RAM for field-upgradable firmware and larger data logs; versus R5F10WLGGFB#30, it adds 15 extra segments and 4 commons for richer display content while retaining identical industrial temperature and ultra-low power specs.

FAQ
What is the operating temperature range of the R5F10WMGGFB#30?
The R5F10WMGGFB#30 is rated for industrial operation from −40°C to +105°C, validated per Renesas industrial qualification standards. This range supports deployment in factory automation panels, outdoor utility meters, and other environments where ambient temperatures exceed consumer-grade limits. The G-suffix explicitly denotes this extended temperature capability.
Does the R5F10WMGGFB#30 support LIN bus communication?
Yes, the R5F10WMGGFB#30 supports LIN bus communication via UART2 - one of its three UART peripherals explicitly designated as LIN-capable in the RL78/L13 datasheet. It meets LIN 2.2 physical layer requirements when paired with an external LIN transceiver, enabling use in automotive body electronics and industrial sub-networks.
How many LCD segments and commons does the R5F10WMGGFB#30 drive?
The R5F10WMGGFB#30 drives up to 51 segment outputs and 8 common outputs, enabling multiplexed LCD configurations such as 51×8. This is confirmed in the datasheet's "Outline of Functions" section and distinguishes it from 64-pin variants (e.g., R5F10WLx) that support only 36 segments and 4 commons.
What debug interface does the R5F10WMGGFB#30 provide?
The R5F10WMGGFB#30 includes a full on-chip debug interface accessible via TOOL0, TOOLRxD, and TOOLTxD pins - compatible with Renesas E2 emulator and standard SWD/JTAG debuggers. It supports breakpoints, watchpoints, flash programming, and real-time variable monitoring without requiring external debug hardware beyond the emulator connection.
Can the R5F10WMGGFB#30 operate from a single 1.8 V supply?
Yes, the R5F10WMGGFB#30 supports operation from 1.6 V to 5.5 V, including stable execution at 1.8 V. At this voltage, the maximum allowed system clock is 16 MHz in HS mode or 4 MHz in LV mode - sufficient for most LCD-driven applications while maintaining ultra-low power consumption (e.g., 71 μA/MHz scaling applies down to 1.8 V).
