Renesas R5F2L3A7CNFP#V0

Overview

R5F2L3A7CNFP#V0 from Renesas Electronics is an 8-bit R8C CPU core MCU in the R8C/L3AC Group, featuring 48 KB program ROM, 6 KB RAM, and 4 KB data flash with background operation (BGO). It delivers 50 ns minimum instruction execution at 20 MHz, integrates a 16×16-bit multiplier, and supports 88 programmable I/O ports including 16 high-current drive pins for LCD segment drivers and peripheral control.

For engineers reviewing the R5F2L3A7CNFP#V0 datasheet, R5F2L3A7CNFP#V0 pinout, R5F2L3A7CNFP#V0 application, or R5F2L3A7CNFP#V0 equivalent, key selection criteria include its 20-channel 10-bit ADC, integrated LCD controller (up to 8 COM / 56 SEG), LIN bus hardware support, and low-power stop mode consuming only 2 µA - critical for battery-powered appliance and industrial HMI designs.

Technical Context

The R5F2L3A7CNFP#V0 implements the R8C CPU core with 89 fundamental instructions and single-chip 1 Mbyte address space, enabling efficient C-language execution. Its system clock generation includes four independent circuits: XIN oscillator (20 MHz max), XCIN 32 kHz crystal input, high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - all selectable via software for dynamic power management.

Peripheral integration centers on mixed-signal timing and interface functions: Timer RD provides three-phase complementary PWM (6-pin output) for motor control; UART0/1/2 support LIN protocol (using UART0 + Timer RA); and the LCD controller integrates voltage multiplier and regulator for bias generation without external components.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for R5F2L3A7CNFP#V0?

R5F2L3A7CNFP#V0 operates at up to 20 MHz when supplied with VCC = 2.7–5.5 V. At lower frequencies (e.g., 5 MHz), it supports extended voltage range down to 1.8 V, enabling compatibility with energy-harvesting or battery-backed systems where supply stability varies.

Does R5F2L3A7CNFP#V0 support hardware LIN communication, and which peripherals are involved?

Yes, R5F2L3A7CNFP#V0 includes a dedicated hardware LIN module compliant with LIN 2.x standards. It uses UART0 for serial framing and Timer RA for accurate baud rate generation and synchronization - offloading protocol timing from firmware and ensuring robust noise immunity in automotive environments.

How many analog input channels does R5F2L3A7CNFP#V0 provide, and what is their resolution?

R5F2L3A7CNFP#V0 features a 10-bit successive-approximation ADC with 20 configurable analog input channels. All channels support sample-and-hold and automatic sweep mode, allowing continuous conversion of multiple sensors without CPU intervention - ideal for thermal monitoring in appliances.

What LCD display configurations are supported by R5F2L3A7CNFP#V0, and does it require external bias circuitry?

R5F2L3A7CNFP#V0 supports up to 8 common outputs and 56 segment outputs with static, 1/2, 1/3, 1/4, and 1/8 duty cycles. Its integrated voltage multiplier and dedicated regulator eliminate the need for external bias ICs or charge-pump capacitors - simplifying design for monochrome character and graphic LCDs.

What low-power modes are available on R5F2L3A7CNFP#V0, and what is the typical current draw in stop mode?

R5F2L3A7CNFP#V0 offers wait, stop, and power-off modes. In stop mode with VCC = 3.0 V, typical current consumption is 2 µA - sufficient for long-term battery operation in remote controls or sensor nodes where wake-up is triggered by external interrupt or RTC alarm.
