FAQ
What is the maximum operating frequency of the R5F2L388BNFP#V2 and under what voltage conditions?
The R5F2L388BNFP#V2 achieves a maximum operating frequency of 20 MHz when supplied with VCC = 2.7–5.5 V. At lower voltages (1.8–2.6 V), the maximum frequency is limited to 5 MHz to ensure timing margin and stability. This dual-voltage/frequency specification allows flexible power management in battery-backed or wide-input-range systems.
Does the R5F2L388BNFP#V2 include data flash memory?
No, the R5F2L388BNFP#V2 does not include data flash memory. It belongs to the R8C/L38B Group, which - per Table 1.1 in REJ03B0243-0030 - omits the 1 KB × 4 blocks with background operation (BGO) function found in the 'A' variants (e.g., R8C/L38A Group). Only program ROM (64 KB) and RAM (8 KB) are available for non-volatile data storage via software emulation or external EEPROM.
Which package type and pin count does the R5F2L388BNFP#V2 use?
The R5F2L388BNFP#V2 uses an 80-pin LQFP package (PLQP0080KB-A), measuring 12 × 12 mm with 0.5 mm pitch. This matches the R8C/L38B Group's standard packaging, as confirmed in Table 1.2 and Figure 1.15 of the preliminary specification REJ03B0243-0030. The #V2 suffix denotes tape-and-reel packaging per Renesas standard.
What LCD capabilities does the R5F2L388BNFP#V2 support?
The R5F2L388BNFP#V2 supports up to 8 common and 48 segment outputs with selectable bias (1/2, 1/3, 1/4) and duty (static, 1/2–1/8). It integrates a voltage multiplier and dedicated regulator, enabling direct LCD drive from 3–5 V supplies without external components. These capabilities are specific to the R8C/L38B Group and verified in Table 1.4 and Section 1.1.3.
Is the R5F2L388BNFP#V2 qualified for industrial temperature operation?
Yes, the R5F2L388BNFP#V2 is the D-version part, rated for -40°C to +85°C operating ambient temperature. This qualification aligns with Renesas' "High Quality" grade for industrial and transportation applications, as defined in Note 7 of the preliminary specification. The 'N' version (e.g., R5F2L388BNFP) is limited to -20°C to +85°C.
