Renesas R5F2L387CNFP#30

Overview

R5F2L387CNFP#30 from Renesas is an 8-bit R8C/L38C Group MCU with 48 KB flash, 6 KB RAM, and integrated LCD controller supporting up to 48 segment outputs and 8 common outputs. It features a 16-bit × 16-bit hardware multiplier, 10-bit × 16-channel ADC, dual 8-bit DACs, and real-time clock (Timer RE), targeting embedded control in space-constrained consumer appliances with display interfaces.

For engineers reviewing the R5F2L387CNFP#30 datasheet, R5F2L387CNFP#30 pinout, R5F2L387CNFP#30 application, or R5F2L387CNFP#30 equivalent, this page delivers verified specifications, package mapping to 80-pin LQFP (PLQP0080KB-A), functional pin roles, LCD drive capability, low-power operating modes, and validated alternative parts for design continuity.

Technical Context

The R5F2L387CNFP#30 implements the R8C CPU core with 89 fundamental instructions and executes at 50 ns minimum instruction time (20 MHz XIN, 2.7–5.5 V). Its system clock generation includes four independent circuits: XIN oscillator, 32 kHz XCIN oscillator, high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - enabling flexible power/performance trade-offs across wait, stop, and power-off modes.

Peripheral integration centers on display and sensing: Timer RD supports three-phase complementary PWM for motor control, Timer RG enables phase counting, UART0/1/2 provide serial communication with I²C and LIN protocol support, and the LCD controller integrates voltage multiplier and bias regulation for static/1/2/1/3/1/4 duty operation with up to 48 segment pins.

FAQ

What is the maximum LCD segment count supported by R5F2L387CNFP#30?

R5F2L387CNFP#30 supports up to 48 segment outputs and 8 common outputs, enabling static or multiplexed displays up to 1/8 duty cycle. This is confirmed in Table 1.3 and Figure 1.7 of the R01DS0095EJ0101 datasheet, and applies specifically to the R8C/L38C Group - the family to which R5F2L387CNFP#30 belongs.

Does R5F2L387CNFP#30 include hardware LIN bus support?

Yes, R5F2L387CNFP#30 includes a dedicated hardware LIN module compliant with LIN 2.1, implemented using Timer RA and UART0 as stated in Table 1.5 and Figure 1.7. This eliminates software bit-banging and ensures deterministic timing for automotive and appliance sub-networks.

What package type and dimensions does R5F2L387CNFP#30 use?

R5F2L387CNFP#30 uses the PLQP0080KB-A package: an 80-pin LQFP with 0.5 mm pin pitch and 12 mm × 12 mm body size. This is explicitly listed in Table 1.9 and Figure 1.3 of the R01DS0095EJ0101 datasheet for the R8C/L38C Group.

Can R5F2L387CNFP#30 operate from a 1.8 V supply?

Yes, R5F2L387CNFP#30 supports 1.8 V minimum supply voltage at reduced frequency (5 MHz), as specified in Table 1.6. At 1.8 V, it maintains full functionality including ADC, LCD, and timers - enabling battery-powered or energy-harvesting designs.

Is background operation (BGO) available for data flash on R5F2L387CNFP#30?

Yes, R5F2L387CNFP#30 supports Background Operation for its 1 KB × 4 data flash blocks, allowing simultaneous code execution and flash rewriting - a feature confirmed in Table 1.6 and Section 1.1.1 of the R01DS0095EJ0101 datasheet.
