Product details
Overview
R5F10WLFGFB#30 from Renesas is a 64-pin RL78/L13 16-bit microcontroller with integrated LCD controller/driver, 96 KB flash, 4 KB data flash, 6 KB RAM, and ultra-low-power operation (71 μA/MHz active, 0.61 μA in RTC+LVD mode). It supports 1.6–5.5 V supply, operates from –40°C to +105°C (industrial grade), and targets battery-powered LCD-based instrumentation, smart meters, and portable medical devices.
For engineers reviewing the R5F10WLFGFB#30 datasheet, R5F10WLFGFB#30 pinout, R5F10WLFGFB#30 application, or R5F10WLFGFB#30 equivalent, key selection criteria include its 96 KB code flash capacity, 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch) package, integrated 36-segment/4-common LCD driver, dual UART + I²C + CSI interfaces, and industrial-temperature qualification (G-grade).
Technical Context
The R5F10WLFGFB#30 implements the RL78 CPU core - a CISC architecture with 3-stage pipeline, 1 MB address space, and configurable instruction timing (0.04167 µs min @ 24 MHz, 30.5 µs @ 32.768 kHz). It integrates a dedicated 16-bit timer KB20 for PWM output and a real-time clock 2 with calendar, alarm, and correction functions.
Its power management includes HALT, STOP, and SNOOZE modes, on-chip POR/LVD (14-level selectable reset/interrupt), and a high-accuracy ±1.0% on-chip oscillator (48/24/16/12/8/6/4/3/2/1 MHz options). The device features 4-channel DMA, 16-bit × 16-bit multiply-accumulate, and background data flash rewriting (1M write cycles, 1.8–5.5 V).

FAQ
What is the maximum operating frequency and instruction throughput of the R5F10WLFGFB#30?
The R5F10WLFGFB#30 supports up to 24 MHz operation using its high-accuracy on-chip oscillator (±1.0%), delivering 31 DMIPS performance. Its minimum instruction execution time is 0.04167 µs at 24 MHz, and it maintains full functionality down to 32.768 kHz for ultra-low-power RTC operation - enabling dynamic clock scaling across active, idle, and deep-sleep states within the same R5F10WLFGFB#30 design.
Does the R5F10WLFGFB#30 support in-system programming and secure firmware updates?
Yes, the R5F10WLFGFB#30 includes full self-programming capability with boot swap function and flash shield window protection. Code flash blocks can be rewritten in-system under application control, and security features such as block erase prohibition prevent unauthorized modification. These capabilities are implemented directly in the R5F10WLFGFB#30 silicon and do not require external programmers for field firmware updates.
How many LCD segments and commons does the R5F10WLFGFB#30 drive, and what bias methods are supported?
The R5F10WLFGFB#30 drives up to 36 segment and 4 common signals (or 32 segments/8 commons via configuration). It supports three LCD bias generation methods: internal voltage boosting (charge pump), capacitor split, and external resistance division - allowing flexible optimization for contrast, power, and external component count in each R5F10WLFGFB#30 implementation.
What are the key differences between the R5F10WLFGFB#30 and the R5F10WLGGB#30?
The R5F10WLFGFB#30 contains 96 KB flash and 6 KB RAM, while the R5F10WLGGB#30 upgrades to 128 KB flash and 8 KB RAM - both in identical 64-pin LFQFP packages with matching peripherals and pinouts. This makes the R5F10WLGGB#30 a drop-in firmware upgrade path for designs needing additional code space, without altering the R5F10WLFGFB#30 hardware layout or driver software.
Can the R5F10WLFGFB#30 operate from a single 1.8 V supply, and what peripherals remain functional?
Yes, the R5F10WLFGFB#30 operates across 1.6–5.5 V, including 1.8 V nominal supply. At 1.8 V, all core functions remain active: 96 KB flash, 6 KB RAM, 10-bit ADC (with internal 1.45 V reference), LCD controller, UART, I²C, and timers. However, high-speed on-chip oscillator operation is limited to ≤16 MHz, and certain analog features (e.g., temperature sensor) are disabled - details are fully specified in the R5F10WLFGFB#30 datasheet electrical characteristics table.
