Product details
Overview
R5F10WMAGFB#50 from Renesas is an 80-pin LFQFP (12 × 12 mm, 0.5 mm pitch), industrial-grade RL78/L13 16-bit MCU with 128 KB flash, 8 KB RAM, integrated LCD controller/driver (51 segment / 4 common outputs), and true low-power operation down to 71 μA/MHz. It features a 24 MHz high-accuracy on-chip oscillator (±1.0%), 12-channel 8/10-bit ADC, dual comparators, and supports LCD-based metering, home appliance control, and industrial HMI panels.
For engineers reviewing the R5F10WMAGFB#50 datasheet, R5F10WMAGFB#50 pinout, R5F10WMAGFB#50 application, or R5F10WMAGFB#50 equivalent, key selection criteria include its industrial temperature range (−40°C to +105°C), integrated LCD drive capability with selectable voltage-boosting methods, ultra-low power HALT/STOP/SNOOZE modes, and support for LIN-bus via UART2 - all critical for battery-powered or thermally demanding embedded displays.
Technical Context
The R5F10WMAGFB#50 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, delivering 31 DMIPS at 24 MHz. Its memory subsystem includes 128 KB code flash (1 KB block size), 4 KB data flash with background operation (BGO) and 1M write endurance, and 8 KB on-chip RAM - enabling robust firmware updates and real-time data logging without halting execution.
Peripherals are tightly integrated for LCD-centric systems: the LCD controller supports internal voltage boosting, capacitor-split, or external resistor-divider biasing; the 16-bit timer array (8 channels) provides PWM, remote carrier output (REMOOUT), and RTC2 calendar functions; and dual comparators with selectable internal/external references enable precision analog monitoring alongside display control.
