Renesas R5F2L368ANFP#V2

Overview

R5F2L368ANFP#V2 from Renesas Electronics is a 16-bit R8C/L36A Group microcontroller featuring 64 KB flash program ROM, 1 KB × 4 data flash with background operation (BGO), and 8 KB RAM in a 64-pin LQFP package. It integrates an R8C CPU core (89 instructions), 52 programmable CMOS I/O ports, 10-bit × 10-channel ADC, dual 8-bit DACs, LCD controller (8 COM / 32 SEG), and multiple timers including PWM-capable Timer RD and real-time clock Timer RE - deployed in appliance control panels requiring integrated display driving and sensor interfacing.

For engineers reviewing the R5F2L368ANFP#V2 datasheet, R5F2L368ANFP#V2 pinout, R5F2L368ANFP#V2 application, or R5F2L368ANFP#V2 equivalent, key selection considerations include its N-grade temperature range (−20°C to +85°C), 20 MHz max operating frequency at 2.7–5.5 V, low-power stop mode (2 µA), and hardware LIN support via UART0 + Timer RA - critical for cost-sensitive consumer HMI designs with display and communication needs.

Technical Context

The R5F2L368ANFP#V2 implements the R8C CPU core with 1 Mbyte address space, 16×16→32-bit multiplier, and multiply-accumulate instruction. Clock generation includes four sources: external XIN (up to 20 MHz), 32 kHz XCIN, high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator - all selectable via software-controlled frequency divider (1/2/4/8/16).

Peripheral integration centers on mixed-signal control: Timer RD provides 6-pin complementary PWM for motor drive, UART2 supports I²C-bus mode, and the LCD controller delivers static/1/2/1/3/1/4 duty bias with integrated voltage multiplier. The DTC (Data Transfer Controller) enables autonomous memory transfers triggered by 38 sources including ADC completion and UART receive.

FAQ

What is the maximum operating frequency of the R5F2L368ANFP#V2 and under what voltage conditions?

The R5F2L368ANFP#V2 supports a maximum operating frequency of 20 MHz when powered at VCC = 2.7–5.5 V. At lower supply voltages down to 1.8 V, the maximum frequency is reduced to 5 MHz to maintain timing margins and stability - verified in Renesas specification Table 1.7.

Does the R5F2L368ANFP#V2 include data flash memory, and what is its endurance rating?

Yes, the R5F2L368ANFP#V2 includes 4 KB of data flash (1 KB × 4 blocks) with background operation (BGO) support. Its programming/erasure endurance is rated at 10,000 cycles - significantly higher than standard program ROM (1,000 cycles) - enabling reliable parameter storage and firmware updates.

What LCD display capabilities does the R5F2L368ANFP#V2 support?

The R5F2L368ANFP#V2 integrates an LCD controller supporting up to 8 common outputs and 32 segment outputs, with selectable bias (1/2, 1/3, 1/4) and duty (static, 1/2, 1/3, 1/4, 1/8). It includes an on-chip voltage multiplier to generate VL1–VL4, eliminating external bias circuitry.

Is hardware LIN bus support available on the R5F2L368ANFP#V2?

Yes, the R5F2L368ANFP#V2 implements a hardware LIN module using UART0 and Timer RA per Renesas documentation - meeting ISO 9141-2 physical layer requirements without external transceivers, simplifying design for automotive body electronics and appliance network nodes.

What low-power modes are available on the R5F2L368ANFP#V2, and what are their typical current draws?

The R5F2L368ANFP#V2 offers wait mode (3.5 µA), stop mode (2 µA), and power-off mode (0.02 µA with Timer RE disabled) at VCC = 3.0 V and XCIN = 32 kHz - enabling ultra-low-power operation in battery-powered remote controls and sensor interfaces.
