Product details
Overview
R5F10WLAGFB#30 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), industrial-grade RL78/L13 16-bit MCU with 128 KB flash, 8 KB RAM, integrated LCD controller/driver (36 segment / 4 common outputs), and true low-power operation down to 71 μA/MHz. It operates from 1.6 V to 5.5 V, supports -40°C to +105°C ambient, and delivers 31 DMIPS at 24 MHz - optimized for battery-powered LCD-based metering and control panels.
For engineers reviewing the R5F10WLAGFB#30 datasheet, R5F10WLAGFB#30 pinout, R5F10WLAGFB#30 application, or R5F10WLAGFB#30 equivalent, key selection criteria include its industrial temperature rating, on-chip LCD driver with voltage-boosting capability, ultra-low power STOP/HALT modes, and dual UART + I²C + CSI interfaces for sensor and display subsystem integration.
Technical Context
The R5F10WLAGFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling minimum instruction execution time of 0.04167 µs at 24 MHz (high-speed on-chip oscillator) or 30.5 µs at 32.768 kHz (subsystem clock). Its memory map spans 1 MB address space, with dedicated data flash (4 KB) supporting background operation and 1,000,000 write cycles.
It integrates a full peripheral suite including 8-channel 16-bit timer array (TAU), real-time clock 2 with calendar and alarm, 2-channel comparator with selectable internal/external reference, 9-channel 8/10-bit ADC, and programmable clock/buzzer output - all managed via centralized interrupt controller with 32 internal and 11 external vectored sources.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10WLGGFB#30 | Same package and pinout; identical 128 KB flash, 8 KB RAM, and peripheral set; differs only in temperature grade (G vs G - same industrial spec) | No functional difference; both rated -40°C to +105°C | Select R5F10WLAGFB#30 when traceability to original Renesas ordering matrix (A-suffix = 128 KB variant) is required for legacy BOM alignment. |
| R5F10WMAGFB#30 | 80-pin LFQFP (12 × 12 mm); adds 3 extra ADC channels (12 vs 9), 3 additional I/O pins, and second UART channel - no pin compatibility | Suitable for designs needing expanded analog sensing or dual serial links (e.g., Modbus + local debug) | Choose R5F10WMAGFB#30 only if PCB layout accommodates larger footprint and additional peripherals are actively used - not a drop-in replacement. |
Compared with R5F10WLGGFB#30, the R5F10WLAGFB#30 offers identical functionality and industrial qualification but ensures strict compliance with Renesas' documented A-suffix memory mapping for 128 KB flash variants; versus R5F10WMAGFB#30, it trades pin count and peripheral headroom for compact 64-pin integration ideal for space-constrained LCD HMI designs.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F10WLAGFB#30?
The R5F10WLAGFB#30 achieves 31 DMIPS at 24 MHz using its high-speed on-chip oscillator. At this frequency, typical active current is 71 μA/MHz - meaning ~1.7 mA total at 24 MHz under standard VDD = 3.3 V and TA = 25°C conditions. Power drops linearly in HALT mode and reaches 0.61 μA in STOP mode with RTC + LVD active.
Does the R5F10WLAGFB#30 support hardware LCD bias generation without external components?
Yes, the R5F10WLAGFB#30 integrates full LCD bias circuitry with three configurable methods: internal voltage boosting, capacitor split, and external resistor division. When using voltage boosting, only two external capacitors (CAPH/CAPL) are required - no external DC-DC converter or bias IC is needed for standard 3V LCDs.
How many UART interfaces does the R5F10WLAGFB#30 provide, and which support LIN bus protocol?
The R5F10WLAGFB#30 provides three UART channels. UART0 and UART1 support LIN bus protocol (LINSEL pin enabled), while UART2 is a standard UART. All three operate independently and can be assigned to different pins via the Peripheral I/O Redirection Register (PIOR) for flexible routing.
What is the purpose of the REGC pin on the R5F10WLAGFB#30, and what capacitor value is recommended?
The REGC pin connects to the internal voltage regulator's stabilization capacitor. Per Renesas specification, it must be connected to VSS via a 0.47 μF to 1.0 μF ceramic capacitor - typically 0.68 μF X7R - to ensure stable core voltage regulation and prevent reset anomalies during LCD segment switching transients.
Can the R5F10WLAGFB#30 perform simultaneous ADC conversion and data flash programming?
Yes, the R5F10WLAGFB#30 supports Background Operation (BGO) for data flash. While executing code from main flash, it can rewrite data flash memory - enabling real-time logging (e.g., sensor history) without halting application logic. This requires proper interrupt masking and sector-lock configuration per the RL78/L13 User's Manual.
