Product details
Overview
R5F10WMGAFA#10 from Renesas is an 80-pin LQFP (14 × 14 mm, 0.65 mm pitch) 16-bit RL78/L13 microcontroller with integrated LCD controller/driver, 128 KB flash, 8 KB RAM, and 4 KB data flash. It delivers 31 DMIPS at 24 MHz, operates from 1.6 V to 5.5 V, and achieves ultra-low power consumption down to 71 μA/MHz - optimized for battery-powered LCD-based consumer instrumentation.
For engineers reviewing the R5F10WMGAFA#10 datasheet, R5F10WMGAFA#10 pinout, R5F10WMGAFA#10 application, or R5F10WMGAFA#10 equivalent, this page provides verified technical context, validated pin functions, real-world LCD interface use cases, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The R5F10WMGAFA#10 implements the RL78 CPU core with CISC architecture and a 3-stage pipeline, supporting instruction execution times from 0.04167 µs (24 MHz high-speed on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.
It integrates dual-clock domain operation: a high-speed main system clock (up to 24 MHz) and a dedicated 32.768 kHz subsystem clock for RTC2 and low-power modes. The on-chip voltage regulator supports direct 1.6–5.5 V operation, while the POR/LVD circuit offers 14-level voltage detection with interrupt or reset capability.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F10WMGAFA#10?
The R5F10WMGAFA#10 achieves 31 DMIPS at 24 MHz using its high-speed on-chip oscillator. At this frequency, typical active current is 71 μA/MHz (≈1.7 mA total), verified per R01DS0168EJ0232 Rev.2.32 Section 2. Electrical Specifications. This value assumes VDD = 3.0 V and TA = 25°C, with all peripherals disabled except core clock.
Does the R5F10WMGAFA#10 support hardware-based LCD bias generation without external components?
Yes, the R5F10WMGAFA#10 integrates three LCD bias methods: internal voltage boosting, capacitor split, and external resistance division. When configured for capacitor split mode, it drives 4-common × 51-segment LCDs using only two external capacitors (CAPH/CAPL), eliminating external charge pumps or resistor networks per R01DS0168EJ0232 Section 1.1 Features.
Can the R5F10WMGAFA#10 generate NEC-standard infrared remote control signals directly?
Yes, the R5F10WMGAFA#10 includes dedicated TKBO (Transmit Key Button Output) pins - TKBO00 (P74), TKBO01-0 (P77), TKBO01-1 (P76), and TKBO01-2 (P75) - which output carrier-modulated signals compliant with NEC protocol timing, as defined in Section 1.3.2 and Figure 1-1 of R01DS0168EJ0232.
What are the key differences between the R5F10WMGAFA#10 and the R5F10WLGAFA#10?
The R5F10WMGAFA#10 uses an 80-pin LQFP package with 65 I/O, 12-channel ADC, TKBO outputs, and 51-segment LCD drive. In contrast, the R5F10WLGAFA#10 is a 64-pin LQFP device with 49 I/O, 9-channel ADC, no TKBO, and max 36-segment drive. Both share 128 KB flash and -40°C to +85°C rating, but pinout and peripheral set differ significantly.
Is the R5F10WMGAFA#10 compatible with Renesas' E2 emulator for on-chip debugging?
Yes, the R5F10WMGAFA#10 supports on-chip debugging via the TOOLRxD/TOOLTxD pins (P17/P00) and TOOL0 (P40), fully compatible with Renesas E2 Emulator (Y-NU-LP-EMUL-E2) and CS+ IDE. Debug functionality includes breakpoints, watchpoints, and flash programming - confirmed in Section 1.1 Features and Chapter 4 of R01DS0168EJ0232.
