Product details
Overview
R5F10WMGAFB#50 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 mode), targeting battery-powered LCD display systems such as smart meters and portable medical devices.
For engineers reviewing the R5F10WMGAFB#50 datasheet, R5F10WMGAFB#50 pinout, R5F10WMGAFB#50 application, or R5F10WMGAFB#50 equivalent, key selection criteria include its 51-segment/8-common LCD drive capability, dual UART + LIN support, 12-channel 10-bit ADC, and industrial-grade temperature range (−40°C to +105°C) enabled by its 'G' suffix.
Technical Context
The R5F10WMGAFB#50 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-supporting instruction execution times from 0.04167 µs (24 MHz on-chip 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 16-bit timer KB20 for high-accuracy PWM generation, two comparators with selectable internal/external reference, and a 12-bit interval timer. The LCD controller supports three voltage-generation methods (internal boost, capacitor split, external resistor division) and configurable segment/common assignments via peripheral I/O redirection register (PIOR).

FAQ
What is the maximum LCD segment count supported by the R5F10WMGAFB#50?
The R5F10WMGAFB#50 supports up to 51 segment outputs and 8 common outputs when configured for 8-common operation (47 segments active). This configuration enables alphanumeric or custom symbol displays without external drivers. The LCD controller supports internal voltage boosting, capacitor-split, and external resistor-division bias methods, allowing flexible panel compatibility. All segment and common signals are routed to dedicated pins (SEG0–SEG50, COM0–COM7) as defined in the 80-pin LFQFP package.
Does the R5F10WMGAFB#50 support LIN bus communication?
Yes, the R5F10WMGAFB#50 supports LIN bus communication through UART0 with dedicated LINSEL pin functionality. When LINSEL is asserted, UART0 operates in LIN mode compliant with LIN 2.2A/SAE J2602 standards-including automatic sync field detection, checksum calculation, and slave node response timing. This eliminates need for external LIN transceivers in body electronics or sensor nodes. The R5F10WMGAFB#50 also provides UART1 and UART3 for concurrent debug or secondary communication channels.
What low-power modes are available on the R5F10WMGAFB#50 and their typical current draw?
The R5F10WMGAFB#50 offers HALT, STOP, and SNOOZE modes. HALT mode draws 0.61 μA while retaining RTC and LVD operation; STOP mode consumes 0.23 μA with RAM retention; SNOOZE enables selective peripheral wake-up (e.g., UART receive, ADC trigger) while CPU remains halted. All modes operate across the full 1.6–5.5 V supply range and −40°C to +105°C temperature span. Current values are measured with RTC running and LVD enabled-verified per Renesas datasheet R01DS0168EJ0232 Rev.2.32.
Can the R5F10WMGAFB#50 perform simultaneous code execution and data flash rewriting?
Yes, the R5F10WMGAFB#50 supports Background Operation (BGO) for data flash. While rewriting the 4 KB data flash memory-used for parameter storage or firmware updates-the CPU executes instructions from code flash without interruption. This capability is essential for fail-safe field updates and real-time logging. BGO is enabled via the DATA_FLASH_BGO bit in the FASFR register and requires proper sector locking/unlocking sequence per the RL78/L13 User's Manual Chapter 3.
What is the function of the PIOR register in the R5F10WMGAFB#50?
The Peripheral I/O Redirection (PIOR) register in the R5F10WMGAFB#50 enables dynamic assignment of alternate functions (e.g., UART, SPI, timer outputs) to non-default pins. For example, CSI00 signals can be moved from P16/P17 to P46/P47, freeing primary ports for GPIO or ADC. This hardware-level remapping simplifies PCB layout and improves signal integrity without requiring external muxing. PIOR is controlled via dedicated SFR bits and requires no CPU overhead once configured-documented in Section 4.9 of the RL78/L13 User's Manual.
