Renesas R5F10WLEAFA#30

Overview

R5F10WLEAFA#30 from Renesas is a 64-pin LQFP (12 × 12 mm, 0.65 mm pitch), 48 KB flash, 2 KB RAM, RL78/L13 16-bit MCU with integrated LCD controller/driver (36 segment/4 common outputs), 9-channel 8/10-bit ADC, and ultra-low power operation (71 μA/MHz active, 0.61 μA in RTC+LVD STOP mode) for battery-powered LCD display systems.

For engineers reviewing the R5F10WLEAFA#30 datasheet, R5F10WLEAFA#30 pinout, R5F10WLEAFA#30 application, or R5F10WLEAFA#30 equivalent, key selection considerations include its consumer-grade temperature range (−40°C to +85°C), on-chip voltage detector with 14-level LVD, 32.768 kHz real-time clock with calendar and alarm, and support for LIN-bus via UART1 - all within a single-supply 1.6 V to 5.5 V operating range.

Technical Context

The R5F10WLEAFA#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). It integrates dual-clock domains: high-speed main system clock (up to 24 MHz) and low-power subsystem clock (32.768 kHz).

Its peripheral set includes an 8-channel timer array unit (TAU) supporting PWM, remote control output (REMOOUT), and 16-bit timer KB20; two comparators with selectable internal/external reference; and serial interfaces comprising CSI00, UART0/UART1 (LIN-capable), and IICA0 - all mapped to dedicated pins with flexible I/O redirection via PIOR register.

FAQ

What is the maximum operating frequency and corresponding power consumption of the R5F10WLEAFA#30?

The R5F10WLEAFA#30 operates up to 24 MHz using its high-speed on-chip oscillator, achieving 31 DMIPS performance. At this frequency, active current is 71 μA per MHz - resulting in ~1.7 mA total at 24 MHz with all peripherals enabled. Its ultra-low-power STOP mode draws only 0.61 μA with RTC2 and LVD active, verified per R01DS0168EJ0232 Rev.2.32.

Does the R5F10WLEAFA#30 support LIN bus communication, and which UART channel implements it?

Yes, the R5F10WLEAFA#30 supports LIN bus communication via UART1 (RxD1/TxD1 on P06/P07), as confirmed in Section 1.1 Features and Table 1-1 of the R01DS0168EJ0232 datasheet. UART1 includes LINSEL functionality and complies with LIN 2.2A specifications, enabling direct integration into automotive body electronics and industrial control networks without external transceivers.

How many LCD segments and commons does the R5F10WLEAFA#30 support, and what drive methods are available?

The R5F10WLEAFA#30 supports 36 segment outputs and 4 common outputs (with optional 8-common configuration yielding 32 segments), as specified in Section 1.1 Features and Table 1-1. It offers three LCD bias methods: internal voltage boosting, capacitor split, and external resistance division - allowing optimization for contrast, power, and external component count based on glass type and supply constraints.

What are the ADC reference options and resolution supported by the R5F10WLEAFA#30?

The R5F10WLEAFA#30 provides 8/10-bit resolution ADC with selectable references: internal 1.45 V bandgap reference, external AVREFP/AVREFM pins, or VDD. The internal reference enables ratiometric measurements independent of supply variation, while dual external reference inputs allow differential sensing - all documented in Section 1.1 Features and Electrical Specifications (Page 17).

Is the R5F10WLEAFA#30 pin-compatible with other RL78/L13 variants in the 64-pin LQFP package?

Yes, the R5F10WLEAFA#30 shares identical 64-pin LQFP (12 × 12 mm, 0.65 mm pitch) pinout and peripheral mapping with all RL78/L13 64-pin variants including R5F10WLAAFA#30 through R5F10WLGAFA#30, as confirmed in Figure 1-1 and Tables 1-1/1-2 of R01DS0168EJ0232. This enables hardware reuse across memory variants without PCB redesign.
