Product details
Overview
R5F10WLCGFB#30 from Renesas is a 64-pin LFQFP ultra-low-power 16-bit RL78/L13 MCU with integrated LCD controller/driver, 16 KB flash, 4 KB data flash, 1 KB RAM, and operation from 1.6 V to 5.5 V across –40°C to +105°C industrial temperature range. It delivers 31 DMIPS at 24 MHz, supports 36-segment/4-common LCD drive, and features HALT/STOP/SNOOZE low-power modes for battery-powered LCD instrumentation.
For engineers reviewing the R5F10WLCGFB#30 datasheet, R5F10WLCGFB#30 pinout, R5F10WLCGFB#30 application, or R5F10WLCGFB#30 equivalent, key selection criteria include its industrial-grade temperature rating, on-chip LCD driver eliminating external bias circuitry, 2-channel comparator with internal reference, 9-channel 8/10-bit ADC, and UART/LIN-capable serial interfaces for smart metering and HMI control.
Technical Context
The R5F10WLCGFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.04167 µs at 24 MHz up to 30.5 µs at 32.768 kHz). Its power management includes dedicated low-speed on-chip oscillator for watchdog and RTC2, plus POR/LVD with 14-level voltage detection.
Peripherals are tightly coupled to the LCD subsystem: VL1–VL4 supply rails support internal boosting/capacitor-split/external-resistor LCD bias methods; COM0–COM7 and SEG0–SEG50 pins provide direct segment/common drive; and TKBO outputs enable infrared remote carrier generation via TAU timer channels.

FAQ
What is the maximum operating frequency and associated current consumption of the R5F10WLCGFB#30?
The R5F10WLCGFB#30 operates up to 24 MHz using its high-accuracy on-chip oscillator (±1.0% over VDD = 1.8–5.5 V, TA = –40 to +85°C). At 24 MHz, typical active current is 71 µA/MHz, equating to ~1.7 mA total. This enables high-performance LCD refresh and sensor processing while maintaining ultra-low power efficiency critical for battery-operated R5F10WLCGFB#30 designs.
Does the R5F10WLCGFB#30 support hardware LCD bias generation without external components?
Yes, the R5F10WLCGFB#30 integrates full LCD bias generation capability. It supports three methods - internal voltage boosting, capacitor split, and external resistance division - all configurable via registers. No external charge pump or bias resistors are required when using internal boosting or capacitor split, significantly reducing BOM count and PCB area for R5F10WLCGFB#30-based displays.
How many analog input channels does the R5F10WLCGFB#30 provide, and what is their resolution?
The R5F10WLCGFB#30 features a 9-channel 8/10-bit successive approximation ADC with VDD as reference. Input channels include ANI0, ANI1, ANI16–ANI25 (mapped to physical pins P21, P20, P22, P26, P27, P10–P13). Resolution is selectable per conversion, supporting both 8-bit (fast) and 10-bit (precision) modes - essential for accurate sensor reading in R5F10WLCGFB#30-based metering applications.
What low-power modes are available on the R5F10WLCGFB#30, and which peripherals remain active in each?
The R5F10WLCGFB#30 offers HALT, STOP, and SNOOZE modes. In STOP mode (0.61 µA), RTC2 and LVD remain active; in SNOOZE mode, selected peripherals like UART or ADC can operate autonomously while CPU sleeps. HALT mode stops the CPU but keeps peripherals running. All modes preserve RAM content and support wake-up via interrupts - a key advantage for R5F10WLCGFB#30 in always-on display applications.
Can the R5F10WLCGFB#30 generate infrared remote control carrier signals?
Yes, the R5F10WLCGFB#30 supports IR carrier generation via its Timer Array Unit (TAU) channels configured as TKBO outputs (TKBO00, TKBO01-0/1/2). These outputs deliver precise 32–56 kHz carrier waveforms synchronized to the subsystem clock (32.768 kHz), enabling direct IR transmission without external encoder ICs - a validated feature used in R5F10WLCGFB#30-based remote-controlled appliances and industrial HMIs.
