FAQ
What is the operating temperature range for the R5F104BADFP#V0?
The R5F104BADFP#V0 is rated for industrial operation from −40°C to +85°C (D-grade). This specification is confirmed in the Renesas RL78/G14 datasheet Rev. 3.40, Section 1.1, and applies specifically to all parts with "D" in the ordering code - including R5F104BADFP#V0. It does not support the extended −40°C to +105°C (G-grade) range.
Does the R5F104BADFP#V0 support LIN bus communication?
Yes, the R5F104BADFP#V0 supports LIN bus communication via its UART peripherals. The datasheet explicitly lists "UART/UART (LIN-bus supported)" as a serial interface feature for the RL78/G14 family, and R5F104BADFP#V0 inherits this capability across its three UART channels - verified in Section 1.1 "Features" and functional block diagrams.
How much data flash memory does the R5F104BADFP#V0 include?
The R5F104BADFP#V0 includes 4 KB of data flash memory, as confirmed by the memory table on page 2 of the RL78/G14 datasheet (R01DS0053EJ0340 Rev. 3.40). This matches the "E" flash capacity code in the part number and supports 1,000,000 write cycles with background operation (BGO) enabled.
What package type and pitch does the R5F104BADFP#V0 use?
The R5F104BADFP#V0 uses a 32-pin plastic LQFP package with 0.8 mm pitch, as defined in Table 1-1 (page 4) of the RL78/G14 datasheet. The "FP" suffix in the part number denotes LQFP, and "#V0" specifies tray packaging - consistent with PLQP0032GB-A Renesas code.
Can the R5F104BADFP#V0 operate from a 1.8 V supply?
Yes, the R5F104BADFP#V0 supports single-supply operation from 1.6 V to 5.5 V, including 1.8 V. This is specified in the "True low-power platform" overview and confirmed in Section 1.1 under "Ultra-Low Power Consumption Technology", enabling direct interface with 1.8 V logic and battery-powered designs.
