Product details
Overview
R5F10WLGAFA#10 from Renesas is a 64-pin LQFP (12 × 12 mm, 0.65 mm pitch), 128 KB flash, 8 KB RAM RL78/L13 microcontroller with integrated LCD controller/driver, 16-bit timer array (8 channels), 9-channel 8/10-bit ADC, and dual comparators - designed for ultra-low-power LCD-based consumer instrumentation including digital thermostats, blood glucose meters, and portable medical displays.
For engineers reviewing the R5F10WLGAFA#10 datasheet, R5F10WLGAFA#10 pinout, R5F10WLGAFA#10 application, or R5F10WLGAFA#10 equivalent, key selection criteria include its 1.6–5.5 V operation range, 71 μA/MHz active current, RTC+LVD standby at 0.61 μA, 31 DMIPS @ 24 MHz, and support for 36-segment/4-common LCD drive without external bias circuitry.
Technical Context
The R5F10WLGAFA#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 HS oscillator). It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor-split, or external resistor-divider bias methods - enabling direct drive of segment-based displays up to 36×4.
Its peripheral set includes three UART channels (one LIN-capable), two CSI/SPI interfaces, one I²C interface, four DMA channels, and a 16-bit timer KB20 for precise PWM generation.

FAQ
What is the maximum operating frequency and associated current consumption of the R5F10WLGAFA#10?
The R5F10WLGAFA#10 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. At this frequency and VDD = 3.3 V, typical active current is 71 μA/MHz - resulting in ~1.7 mA total at full speed. This value is confirmed in Section 2.1 of the R01DS0168EJ0232 datasheet under "Current Consumption (Active Mode)".
Does the R5F10WLGAFA#10 support hardware-based LCD bias generation without external components?
Yes, the R5F10WLGAFA#10 integrates an LCD controller with internal voltage boosting, capacitor-split, and external resistor-divider bias methods. When configured for internal boosting, it generates required LCD voltages directly - eliminating external charge pumps or bias resistors. This capability is documented in Section 1.1 "LCD controller/driver" and Figure 1-11 of the R01DS0168EJ0232 datasheet.
How many ADC channels does the R5F10WLGAFA#10 provide, and what reference options are available?
The R5F10WLGAFA#10 provides 9 analog input channels with 8/10-bit resolution. It supports internal 1.45 V reference voltage and external reference inputs (IVREF0/IVREF1), enabling accurate measurements across varying supply conditions. These specifications are listed in Section 1.1 "A/D converter" and Table 1-1 of the R01DS0168EJ0232 datasheet.
What packaging and lead pitch does the R5F10WLGAFA#10 use, and is it RoHS-compliant?
The R5F10WLGAFA#10 uses a 64-pin plastic LQFP package with 12 × 12 mm body and 0.65 mm lead pitch (ordering code FA). It is RoHS-compliant and rated MSL Level 3. This information is specified in Section 1.2 "List of Part Numbers" and Table 1-1 of the R01DS0168EJ0232 datasheet.
Can the R5F10WLGAFA#10 operate from a single 1.8 V supply, and what features remain functional?
Yes, the R5F10WLGAFA#10 supports 1.6 V to 5.5 V operation. At 1.8 V, all core functions remain active including CPU execution, 128 KB flash access, 8 KB RAM, LCD controller/driver, 9-channel ADC (with internal reference), and UART/CSI/I²C interfaces. This is verified in Section 1.1 "Ultra-low power consumption technology" and Section 2.1 "Electrical Specifications" of the R01DS0168EJ0232 datasheet.
