Product details
Overview
R5F10WMAGFB#10 from Renesas is an 80-pin LFQFP ultra-low-power 16-bit MCU in the RL78/L13 family, integrating LCD controller/driver (51 segment / 4 common), 128 KB flash, 4 KB data flash, 8 KB RAM, and a 24 MHz RL78 CPU core delivering 31 DMIPS. It operates from 1.6 V to 5.5 V, supports HALT/STOP/SNOOZE modes (down to 0.61 μA RTC+LVD), and targets battery-powered LCD-based industrial instrumentation.
For engineers reviewing the R5F10WMAGFB#10 datasheet, R5F10WMAGFB#10 pinout, R5F10WMAGFB#10 application, or R5F10WMAGFB#10 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +105°C), integrated LCD drive capability with voltage-boosting options, 12-channel 10-bit ADC, dual comparators, and LIN-capable UART for smart metering and HMI control systems.
Technical Context
The R5F10WMAGFB#10 implements the RL78 CISC CPU core with 3-stage pipeline, 1 MB address space, and configurable instruction timing (0.04167 µs min @ 24 MHz). Its power management includes on-chip POR, 14-level LVD, and three low-power modes optimized for intermittent sensing and display update cycles.
Peripherals are organized into dedicated units: Timer Array Unit (TAU) with eight 16-bit channels supporting PWM and remote carrier output; Serial Array Unit (SAU) with four UART/CSI/I²C channels; and a dedicated 16-bit timer KB20 for high-accuracy timing. The LCD controller supports internal voltage boosting, capacitor-split, or external resistor-divider bias methods.

The R5F10WMAGFB#10 achieves a maximum CPU frequency of 24 MHz using the high-speed on-chip oscillator, delivering 31 DMIPS performance. This is confirmed in the datasheet's "Features" section and validated under VDD = 1.8–5.5 V and TA = −40°C to +105°C conditions. The RL78 core's 3-stage pipeline enables consistent throughput across voltage and temperature ranges.
Does the R5F10WMAGFB#10 support hardware-based LIN bus communication?
Yes, the R5F10WMAGFB#10 supports LIN 2.2 protocol via UART2 channel, which includes automatic sync-break detection, checksum calculation, and LIN-specific framing. This capability is explicitly documented in Section 1.1 "Features" and Section 1.6 "Outline of Functions" of the R01DS0168EJ0232 datasheet.
How many LCD segments and commons can the R5F10WMAGFB#10 drive, and what bias methods are supported?
The R5F10WMAGFB#10 drives up to 51 segment outputs and 4 common outputs (or 47 segments / 8 commons when configured for 8-com mode). It supports three bias methods: internal voltage boosting, capacitor-split, and external resistance division-enabling flexible display compatibility without external components in most configurations.
What is the guaranteed minimum data flash endurance for the R5F10WMAGFB#10?
The R5F10WMAGFB#10 guarantees 1,000,000 write/erase cycles for its 4 KB data flash memory, specified as "TYP." in the datasheet's "Data flash memory" subsection. This endurance applies across the full industrial temperature range (−40°C to +105°C) and VDD = 1.8–5.5 V, enabling reliable parameter storage in field-deployed equipment.
Is the R5F10WMAGFB#10 pin-compatible with other RL78/L13 80-pin variants like R5F10WMEGFB#10?
Yes, all RL78/L13 80-pin LFQFP variants-including R5F10WMAGFB#10 and R5F10WMEGFB#10-share identical pinouts, package dimensions (12 × 12 mm, 0.5 mm pitch), and electrical characteristics. Differences are limited to flash/RAM capacity and factory-programmed security settings, allowing drop-in replacement during design iteration or cost optimization.
