FAQ
What is the maximum LCD segment count supported by the R5F111PEGFB#10?
The R5F111PEGFB#10 supports up to 56 segment outputs and 8 common outputs, enabling direct drive of multiplexed LCDs with up to 448 (56 × 8) segments. This is confirmed in the RL78/L1C datasheet Section 1.1 under "LCD controller/driver" and verified in the 100-pin block diagram (Page 14). The R5F111PEGFB#10 achieves this using its integrated voltage boosting and capacitor-split methods, eliminating need for external LCD bias generators.
Does the R5F111PEGFB#10 include USB device functionality?
Yes, the R5F111PEGFB#10 includes a USB 2.0 function controller supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) operation, with Battery Charging Specification Revision 1.2 compliance. This is explicitly stated in the "USB" subsection of Section 1.1 (Page 1) and confirmed in the 100-pin with-USB block diagram (Page 14). The R5F111PEGFB#10 requires UREGC, UVBUS, UDP, and UDM pins for physical layer implementation.
What is the operating temperature range for the R5F111PEGFB#10?
The R5F111PEGFB#10 is rated for industrial operation from −40°C to +105°C, indicated by the "G" suffix in its part number per Renesas' ordering guide (Page 3). This is distinct from consumer-grade "A" variants (−40°C to +85°C). The R5F111PEGFB#10's thermal specification is validated across all integrated peripherals including LCD driver, USB transceiver, and A/D converter.
How much data flash memory does the R5F111PEGFB#10 provide?
The R5F111PEGFB#10 includes 8 KB of data flash memory, supporting background operation (BGO), 1,000,000 write cycles (typical), and rewrite voltage range of 1.8–3.6 V. This is specified in Section 1.1 "Data flash memory" (Page 1) and cross-referenced in the memory table for "Products with USB" (Page 2). The R5F111PEGFB#10 uses this for parameter storage, calibration data, or firmware update staging without halting application code.
Which A/D converter resolution and input count are available on the R5F111PEGFB#10?
The R5F111PEGFB#10 features a 12-bit A/D converter with 12 analog input channels, operable at 2.4–3.6 V supply. It also supports 8/10-bit modes at 1.6–3.6 V, but the 12-bit mode is the highest-resolution option. This is documented in Section 1.1 "A/D converter" (Page 1) and confirmed in the 100-pin block diagram showing 12-channel analog input routing (Page 14). The R5F111PEGFB#10 uses internal 1.45 V reference for high-accuracy measurements.
