Product details
Overview
R5F10WMCAFB#10 from Renesas is an 80-pin RL78/L13 16-bit microcontroller with integrated LCD controller/driver, 32 KB flash memory, 4 KB data flash, and 1.5 KB RAM. It operates from 1.6 V to 5.5 V, delivers 31 DMIPS at 24 MHz, and achieves ultra-low power consumption (71 μA/MHz active, 0.61 μA in RTC+LVD STOP mode), targeting battery-powered LCD display systems such as smart meters and portable medical devices.
For engineers reviewing the R5F10WMCAFB#10 datasheet, R5F10WMCAFB#10 pinout, R5F10WMCAFB#10 application, or R5F10WMCAFB#10 equivalent, key selection criteria include its 51-segment/8-common LCD drive capability, dual UART + I²C + CSI interfaces, 12-channel 10-bit ADC, and support for LIN-bus communication - all within a compact 12 × 12 mm LFQFP-80 package with 0.5 mm pitch.
Technical Context
The R5F10WMCAFB#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.04167 µs (24 MHz on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space, with dedicated 4 KB data flash enabling background operation (BGO) and 1,000,000 write cycles.
Power management includes HALT, STOP, and SNOOZE modes, on-chip POR/LVD with 14 selectable voltage detection levels, and dual clock domains: high-speed main system clock (up to 24 MHz) and low-power subsystem clock (32.768 kHz). The integrated LCD controller supports three bias methods - internal voltage boosting, capacitor split, and external resistor division - for flexible segment/common drive configurations.

FAQ
What is the maximum operating frequency and associated current consumption of the R5F10WMCAFB#10?
The R5F10WMCAFB#10 achieves 31 DMIPS at 24 MHz using its high-speed on-chip oscillator. At this frequency and VDD = 3.3 V, typical active current is 71 μA per MHz - resulting in ~1.7 mA total active current. This value scales linearly with clock speed, enabling precise power budgeting across performance modes.
Does the R5F10WMCAFB#10 support true hardware LCD bias generation without external components?
Yes, the R5F10WMCAFB#10 integrates an internal voltage boosting circuit for LCD bias, allowing direct drive of up to 51 segments and 8 commons without external charge pumps or resistors. The device also supports capacitor-split and external resistor-division methods, giving designers full flexibility to optimize contrast, power, and bill-of-materials.
How many UART interfaces does the R5F10WMCAFB#10 provide, and which support LIN protocol?
The R5F10WMCAFB#10 includes three UART interfaces: UART0, UART1, and UART2. Only UART2 features the dedicated LINSEL pin and built-in LIN physical layer timing compliance, making it the sole channel capable of native LIN 2.2 communication without external transceivers.
Can the R5F10WMCAFB#10 execute code while rewriting data flash memory?
Yes, the R5F10WMCAFB#10 supports Background Operation (BGO) for data flash. During 4 KB data flash erase/write cycles, the CPU can continue executing instructions from code flash - eliminating firmware stalls and enabling seamless over-the-air updates or parameter logging in real time.
What is the pin-compatible upgrade path from the R5F10WMCAFB#10 within the RL78/L13 family?
No pin-compatible upgrade exists within the RL78/L13 family that retains the exact 80-pin LFQFP-0.5 mm footprint while increasing flash beyond 32 KB. The R5F10WMDAFB#10 shares the same package and pinout but doubles flash to 64 KB - making it the direct memory upgrade option without PCB redesign.
