Product details
Overview
R5F10WMCAFB#30 from Renesas is an 80-pin RL78/L13 16-bit microcontroller with integrated LCD controller/driver, 64 KB flash, 4 KB data flash, 4 KB RAM, and ultra-low power operation (71 μA/MHz active, 0.61 μA RTC+LVD). It supports 1.6–5.5 V supply, -40°C to +85°C ambient, and targets battery-powered LCD instrumentation such as digital multimeters and portable medical displays.
For engineers reviewing the R5F10WMCAFB#30 datasheet, R5F10WMCAFB#30 pinout, R5F10WMCAFB#30 application, or R5F10WMCAFB#30 equivalent, key selection criteria include its 51-segment/8-common LCD drive capability, dual UART + I²C + CSI interfaces, 12-channel 10-bit ADC, and hardware RTC with calendar and alarm-critical for human-interface embedded systems requiring long battery life and direct segment-based display control.
Technical Context
The R5F10WMCAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.04167 µs min @ 24 MHz high-speed on-chip oscillator). It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor-split, or external resistor-divider bias methods.
Its peripheral set includes 8-channel 16-bit Timer Array Unit (TAU), 1-channel 16-bit timer KB20, 12-bit interval timer, real-time clock 2 (RTC2) with calendar function, 2-channel comparator, and 4-channel DMA-enabling precise timing, low-power wake-up, and background data flash rewriting without CPU intervention.

FAQ
What is the maximum LCD segment count supported by the R5F10WMCAFB#30?
The R5F10WMCAFB#30 supports up to 51 segment outputs with 4 common lines, or 47 segments with 8 common lines-configurable via software-controlled bias method selection (internal voltage boosting, capacitor split, or external resistor division). This matches standard 4-line alphanumeric LCD modules used in portable instrumentation.
Does the R5F10WMCAFB#30 support hardware real-time clock with calendar functionality?
Yes, the R5F10WMCAFB#30 integrates Real-Time Clock 2 (RTC2) with full calendar support (year/month/day/hour/minute/second), alarm interrupt, automatic leap-year correction, and 1 Hz RTC1HZ output. It operates independently in STOP mode using the 32.768 kHz subsystem clock, enabling timekeeping during ultra-low-power sleep.
Can the R5F10WMCAFB#30 perform background data flash writes while executing application code?
Yes, the R5F10WMCAFB#30 supports Background Operation (BGO) for data flash. While rewriting the 4 KB data flash memory, the CPU can continue executing instructions from code flash-enabling seamless firmware parameter updates, event logging, or calibration storage without interrupting real-time tasks.
What are the key low-power modes available on the R5F10WMCAFB#30 and their typical current draw?
The R5F10WMCAFB#30 offers HALT (0.61 μA), STOP (0.23 μA), and SNOOZE modes. In STOP mode with RTC2 and LVD active, it draws just 0.61 μA-verified at VDD = 3.0 V, TA = 25°C. All modes retain RAM content and support wake-up via external interrupt, RTC alarm, or key return detection.
Is the R5F10WMCAFB#30 pin-compatible with other RL78/L13 80-pin variants like R5F10WMEAFB#30?
Yes, all RL78/L13 80-pin LFQFP variants-including R5F10WMCAFB#30, R5F10WMEAFB#30, and R5F10WMGAFB#30-share identical pinout, package dimensions (12 × 12 mm, 0.5 mm pitch), and electrical characteristics. Memory size differences (64 KB vs. 48 KB vs. 128 KB) do not affect physical or functional pin compatibility.
