FAQ
What is the maximum LCD segment count supported by the R5F10WLAAFB#10?
The R5F10WLAAFB#10 supports up to 36 segment outputs and 4 common outputs using its integrated LCD controller/driver. When configured for 8-common operation (via software register setting), it can drive up to 32 segments. This configuration is fixed per hardware variant - the R5F10WLAAFB#10 does not support the 51-segment capability found in 80-pin RL78/L13 variants like R5F10WMAAFB#10.
Does the R5F10WLAAFB#10 include an internal temperature sensor?
Yes, the R5F10WLAAFB#10 includes an on-chip temperature sensor usable only in HS (high-speed main) mode. It is accessible via the 10-bit ADC channel and provides calibrated readings referenced to the internal 1.45 V reference voltage. The sensor output is documented in the RL78/L13 User's Manual Chapter 24 and requires ADC conversion and linear compensation per datasheet coefficients.
Can the R5F10WLAAFB#10 operate from a single 1.8 V supply?
Yes, the R5F10WLAAFB#10 supports operation from 1.6 V to 5.5 V across its full -40°C to +85°C temperature range. At 1.8 V, it can run in LV (low-voltage main) mode up to 4 MHz or in LS (low-speed main) mode up to 8 MHz, enabling compatibility with single-cell lithium or alkaline batteries without external regulators.
What debug interface does the R5F10WLAAFB#10 use?
The R5F10WLAAFB#10 uses Renesas' on-chip debug interface accessed via three dedicated pins: TOOL0 (P40), TOOLRxD (P17), and TOOLTxD (P00). This interface supports full breakpoint, step, and memory inspection capabilities through E2 studio and Renesas Flash Programmer tools - no external JTAG adapter is required.
Is the R5F10WLAAFB#10 pin-compatible with other RL78/L13 64-pin variants?
Yes, all RL78/L13 64-pin variants - including R5F10WLAAFB#10, R5F10WLCAFB#10, and R5F10WLD...FB#10 - share identical LFQFP-64 pinouts and electrical characteristics. Memory size differences (16 KB vs. 32 KB vs. 48 KB flash) do not affect pin function mapping, enabling direct PCB reuse across firmware-scaling SKUs.
