Yes, the R5F100GHAFB#10 supports LIN bus communication through its UART peripherals configured in LIN mode, compliant with ISO 17987. It generates accurate LIN break fields and sync fields in hardware, handles checksum calculation, and supports both master and slave roles. This capability is confirmed in Section 1.1 Features and Section 17.3.1 of the R01DS0131EJ0380 datasheet, eliminating need for external LIN transceivers in basic implementations.
How much data flash memory does the R5F100GHAFB#10 include, and what is its endurance?
The R5F100GHAFB#10 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash. This is documented in Section 1.1 Features and Table 1-1 of the R01DS0131EJ0380 datasheet, enabling robust parameter storage and firmware update staging without system interruption.
What package type and pin count does the R5F100GHAFB#10 use?
The R5F100GHAFB#10 uses a 48-pin LFQFP package (7 mm × 7 mm, 0.5 mm pitch), identified by the "FB" suffix per Renesas part numbering rules in Figure 1-1 of R01DS0131EJ0380. This package is RoHS-compliant, moisture sensitivity level 3, and shares pin compatibility with other RL78/G13 48-pin variants like R5F100GFAFB#10 and R5F100GGAFB#10.
Can the R5F100GHAFB#10 operate from a single 1.8 V supply?
Yes, the R5F100GHAFB#10 supports operation from 1.6 V to 5.5 V, including 1.8 V nominal supply. At 1.8 V, it achieves up to 16 MHz operation (per Section 1.1 Features), with full functionality of ADC (using internal 1.45 V reference), RTC, and low-power modes. All electrical characteristics-including current consumption and timing-are specified down to 1.6 V in the Absolute Maximum Ratings and DC Characteristics tables of R01DS0131EJ0380.
