FAQ
What is the maximum LCD segment count supported by the R5F111PEGFB#30?
The R5F111PEGFB#30 supports up to 56 segment outputs and 4 common outputs, enabling 1/4-duty, 1/5-duty, or 1/8-duty multiplexed LCD displays. This configuration accommodates full alphanumeric characters plus custom icons on a single chip without external drivers, verified in Section 1.1 and Figure 1-1 of R01DS0192EJ0240.
Does the R5F111PEGFB#30 include USB functionality?
No, the R5F111PEGFB#30 is part of the "products without USB" family per Section 1.2 of R01DS0192EJ0240. Its orderable part number prefix "R5F111" explicitly denotes USB exclusion, unlike "R5F110" variants. USB-related pins (UREGC, UBUS, UDP, UDM) are unimplemented and must remain unconnected.
What are the key low-power modes available on the R5F111PEGFB#30?
The R5F111PEGFB#30 supports HALT (112.5 μA/MHz), STOP (0.68 μA with RTC2 + LVD active), and SNOOZE modes. STOP mode retains RAM and RTC2 operation while disabling CPU and most peripherals - validated in Section 1.1 "Ultra-low power consumption technology" and Table 1.2 of R01DS0192EJ0240.
Can the R5F111PEGFB#30 perform simultaneous analog measurements and LCD refresh?
Yes, the R5F111PEGFB#30 uses its Data Transfer Controller (DTC) and Event Link Controller (ELC) to autonomously trigger ADC conversions and update LCD RAM without CPU intervention. This concurrent operation is confirmed in Sections 1.1 and 1.5.4 of R01DS0192EJ0240, enabling deterministic real-time behavior in metering applications.
What is the operating voltage range and temperature grade for the R5F111PEGFB#30?
The R5F111PEGFB#30 operates from 1.6 V to 3.6 V and is rated for industrial temperature range −40°C to +105°C, indicated by the "G" suffix in its part number per Section 1.2 ordering information. This specification is confirmed in Section 1.1 "VDD = single power supply voltage of 1.6 to 3.6 V" and "TA = −40 to +105°C (G: Industrial applications)".
