FAQ
What is the maximum operating frequency and associated current consumption of the R5F10WMDGFB#10?
The R5F10WMDGFB#10 achieves 31 DMIPS at 24 MHz using its high-accuracy ±1.0% on-chip oscillator. At this speed and VDD = 3.3 V, typical active current is 71 μA/MHz - meaning ~1.7 mA total at 24 MHz. This value scales linearly with clock frequency, enabling dynamic power scaling across HALT, STOP, and SNOOZE modes.
Does the R5F10WMDGFB#10 support hardware-based LCD bias generation without external components?
Yes, the R5F10WMDGFB#10 integrates full LCD bias generation with three configurable methods: internal voltage boosting (for 3–5 V supplies), capacitor split (for 2.7–3.3 V), and external resistor division (for 1.8–2.5 V). No external charge pump or bias IC is required, reducing BOM count and PCB area for all supported LCD types.
How many UART interfaces does the R5F10WMDGFB#10 provide, and which support LIN bus protocol?
The R5F10WMDGFB#10 provides three UART interfaces: UART0, UART1, and UART3. UART0 supports LIN bus protocol (LINSEL pin enabled), making it suitable for automotive body electronics and industrial sub-networks. UART1 and UART3 operate in standard asynchronous mode with full baud rate flexibility and noise filtering.
What is the endurance and voltage range for data flash programming on the R5F10WMDGFB#10?
The R5F10WMDGFB#10 data flash supports 1,000,000 write/erase cycles (typical) and operates across the full VDD range of 1.8–5.5 V. Background operation (BGO) allows code execution from program memory during data flash rewrite, enabling seamless firmware updates and parameter storage without system interruption.
Is the R5F10WMDGFB#10 pin-compatible with other RL78/L13 80-pin variants such as R5F10WMAGFB#10 or R5F10WMGGFB#10?
Yes, all RL78/L13 80-pin variants-including R5F10WMDGFB#10, R5F10WMAGFB#10, and R5F10WMGGFB#10-share identical LFQFP-80 (PLQP0080KB-B) mechanical footprint and pinout. Differences are limited to flash/RAM size and temperature grade; no PCB redesign is needed when migrating between G-grade members of the same pin count.
