FAQ
What is the operating temperature range for the R5F100SJAFB#30?
The R5F100SJAFB#30 is rated for industrial operation from –40°C to +85°C (D-grade), validated across the full voltage range (1.6 V to 5.5 V) and all low-power modes. This specification is confirmed in the RL78/G13 datasheet Rev.3.80, Section 1.1 Features, under "Operating ambient temperature".
Does the R5F100SJAFB#30 support LIN bus communication?
Yes, the R5F100SJAFB#30 supports LIN 2.2 communication through its UART peripheral, which includes LIN break detection, sync field processing, and checksum generation. This capability is documented in the "Serial interface" section of the RL78/G13 datasheet, confirming LIN functionality for all variants with UART channels.
How much data flash memory does the R5F100SJAFB#30 include?
The R5F100SJAFB#30 includes 8 KB of on-chip data flash memory, supporting background operation (BGO), 1,000,000 write/erase cycles (typical), and programming at VDD = 1.8 V to 5.5 V. This value is explicitly listed in the memory capacity table on page 2 of the RL78/G13 datasheet R01DS0131EJ0380.
What package type and pin count does the R5F100SJAFB#30 use?
The R5F100SJAFB#30 uses a 128-pin LFQFP package with 0.5 mm pitch, as indicated by the "FB" suffix in the part number and confirmed in Table 1-1 (page 12) of the RL78/G13 datasheet. The Renesas code PLQP0128KD-A identifies this as a lead-free, fine-pitch quad flat package.
Can the R5F100SJAFB#30 operate from a single 1.8 V supply?
Yes, the R5F100SJAFB#30 supports operation from 1.6 V to 5.5 V, including stable execution at 1.8 V. At this voltage, maximum frequency is reduced per the datasheet's voltage-frequency curve, but all peripherals-including ADC, RTC, and UART-remain fully functional with specified timing margins.
