For engineers reviewing the R5F2L38CCNFA#V0 datasheet, R5F2L38CCNFA#V0 pinout, R5F2L38CCNFA#V0 application, or R5F2L38CCNFA#V0 equivalent, this page delivers verified specifications, package mapping, I/O configuration, real-time clock capability, and direct alternative part guidance for design-in and BOM optimization.

Technical Context

The R5F2L38CCNFA#V0 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and multiply-accumulate support-enabling efficient signal processing and motor control loops. It operates across a 1 Mbyte address space in single-chip mode.

It integrates dual UARTs (UART0/UART1), one LIN-capable UART2 (with timer RA and UART0), I²C bus, SSU, 16-bit Timer RD with complementary PWM for three-phase motor drive, and Timer RE for real-time clock functionality-all synchronized to configurable on-chip oscillators (high-speed, low-speed, 32 kHz XCIN).

FAQ

What is the maximum LCD segment count supported by R5F2L38CCNFA#V0?

R5F2L38CCNFA#V0 supports up to 48 segment outputs and 8 common outputs, enabling static, 1/2, 1/3, 1/4, or 1/8 duty LCD configurations. This matches the R8C/L38C Group specification confirmed in Table 1.3 and Figure 1.7 of the R01DS0095EJ0101 datasheet. The device integrates dedicated VL1–VL4 bias supplies and CL1/CL2 clocks to drive these segments without external components.

Does R5F2L38CCNFA#V0 include hardware LIN support?

Yes, R5F2L38CCNFA#V0 includes a hardware LIN module that uses UART0 and timer RA per the R8C/L38C Group functional description in Section 1.1.1 and block diagram (Figure 1.7). This enables ISO 9141-2 and SAE J2602 compliance without external transceivers-critical for automotive body electronics integration.

What are the operating voltage and temperature ranges for R5F2L38CCNFA#V0?

R5F2L38CCNFA#V0 operates from 1.8 V to 5.5 V and is rated for −20°C to +85°C ambient temperature (N version, as indicated by the "N" in the part number suffix). This is explicitly defined in Table 1.6 (Operating Ambient Temperature) and confirmed by the "N" classification in Figure 1.3 of the R01DS0095EJ0101 datasheet.

How many programmable I/O ports does R5F2L38CCNFA#V0 provide?

R5F2L38CCNFA#V0 provides 68 programmable CMOS I/O ports with selectable pull-up resistors, as specified in Table 1.1 (Differences between Groups) and Table 1.2 (Programmable I/O Ports Provided for Each Group) of the R01DS0095EJ0101 datasheet. Eight of these are high-current drive ports capable of >20 mA.

Is background operation (BGO) supported for data flash on R5F2L38CCNFA#V0?

Yes, R5F2L38CCNFA#V0 supports background operation (BGO) for data flash, allowing read/execute operations during erase or write cycles. This is documented in Table 1.6 (Specifications (3)) and Section 1.1 (Features) of the R01DS0095EJ0101 datasheet, enabling seamless firmware updates and parameter logging in real-time systems.
