Product details
Overview
R5F10WMDGFB#50 from Renesas is an RL78/L13 16-bit ultra-low-power MCU with integrated LCD controller/driver, 32 KB flash, 4 KB data flash, 1.5 KB RAM, and operation from 1.6 V to 5.5 V. It delivers 31 DMIPS at 24 MHz, supports 36-segment/4-common LCD drive, and targets battery-powered LCD displays in industrial temperature range (−40°C to +105°C).
For engineers reviewing the R5F10WMDGFB#50 datasheet, R5F10WMDGFB#50 pinout, R5F10WMDGFB#50 application, or R5F10WMDGFB#50 equivalent, key selection criteria include its true low-power HALT/STOP/SNOOZE modes (71 μA/MHz active, 0.61 μA RTC+LVD), 12-channel 10-bit ADC, dual comparators, and 80-pin LFQFP package with 65 I/Os including key interrupt and remote control output.
Technical Context
The R5F10WMDGFB#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.04167 µs @ 24 MHz to 30.5 µs @ 32.768 kHz). It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor split, or external resistor division methods for segment drive.
Its peripheral set includes four UART channels (one LIN-capable), two CSI interfaces, one I²C interface, eight 16-bit timer channels, one 16-bit KB20 timer, real-time clock 2 with calendar and alarm, and a 4-channel DMA controller - all operating within the same ultra-low-power envelope.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F10WMDGFB#50?
The R5F10WMDGFB#50 operates up to 24 MHz using its high-accuracy on-chip oscillator (±1.0%), delivering 31 DMIPS. At this speed, minimum instruction execution time is 0.04167 µs. The device also supports lower-frequency modes (e.g., 32.768 kHz subsystem clock) for ultra-low-power RTC operation, with instruction time extending to 30.5 µs.
Does the R5F10WMDGFB#50 support external crystal oscillators for both main and subsystem clocks?
Yes, the R5F10WMDGFB#50 supports external crystals on X1/X2 pins for the main system clock (up to 20 MHz) and on XT1/XT2 pins for the subsystem clock (32.768 kHz). This enables precise timing for real-time clock functions and high-accuracy system operation independent of the on-chip oscillator.
How many LCD segments and commons does the R5F10WMDGFB#50 support, and what drive methods are available?
The R5F10WMDGFB#50 supports up to 51 segment outputs and 8 common outputs. Drive methods include internal voltage boosting, capacitor split, and external resistance division - selectable via register configuration to match display type and power requirements without external components.
What are the key low-power modes supported by the R5F10WMDGFB#50, and what is the typical current consumption in each?
The R5F10WMDGFB#50 supports HALT (71 μA/MHz), STOP (0.61 μA with RTC + LVD active), and SNOOZE (low-power background flash programming) modes. STOP mode maintains RTC and voltage detection functionality while minimizing current draw - critical for battery-backed applications requiring decades of shelf life.
Can the R5F10WMDGFB#50 perform simultaneous analog measurements and LCD refresh without CPU intervention?
Yes. The R5F10WMDGFB#50 uses its 4-channel DMA controller to autonomously transfer ADC conversion results to memory and update LCD RAM, enabling concurrent analog acquisition and display refresh. This offloads the CPU and maintains deterministic timing for both functions in real-time systems.
