Overview
R5F2L3ACMNFP#30 from Renesas is a 16-bit R8C/L3AM Group microcontroller featuring an R8C CPU core, 128 KB flash program memory, 10 KB RAM, and integrated LCD drive control supporting up to 8 common and 56 segment outputs. It delivers 50 ns minimum instruction execution at 20 MHz, includes a 16×16→32-bit hardware multiplier, and targets embedded control in appliance front panels with integrated display and analog sensing.
For engineers reviewing the R5F2L3ACMNFP#30 datasheet, R5F2L3ACMNFP#30 pinout, R5F2L3ACMNFP#30 application, or R5F2L3ACMNFP#30 equivalent, this page provides verified technical context, package mapping, real-world use cases, and validated alternative options for industrial appliance MCU selection.
Technical Context
The R5F2L3ACMNFP#30 implements the R8C CPU core with 89 fundamental instructions and supports a full 1 Mbyte address space. Its clock system integrates four independent sources: XIN (up to 20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (with frequency adjustment), and low-speed on-chip oscillator - all selectable via software-controlled frequency dividers (1/2/4/8/16).
Peripheral integration includes Timer RD (16-bit × 2, supporting 6-pin PWM, complementary three-phase output, and reset-synchronous PWM), 20-channel 10-bit A/D converter with sample-and-hold and sweep mode, dual 8-bit D/A converters, LIN module (using Timer RA and UART0), and hardware I²C bus shared with SSU. The device supports background operation (BGO) for data flash reprogramming during runtime.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for R5F2L3ACMNFP#30?
R5F2L3ACMNFP#30 operates at up to 20 MHz when supplied with 2.7–5.5 V. At lower frequencies (e.g., 5 MHz), it supports down to 1.8 V, enabling ultra-low-power operation in battery-backed subsystems. This dual-voltage capability allows flexible power architecture design without sacrificing performance where needed.
Does R5F2L3ACMNFP#30 support in-system programming of its data flash during normal operation?
Yes, R5F2L3ACMNFP#30 supports background operation (BGO) for data flash, allowing read-modify-write operations on its 1 KB × 4 data flash blocks while the CPU executes application code. This enables seamless firmware parameter updates, calibration storage, and event logging without interrupting real-time control tasks.
How many analog input channels does R5F2L3ACMNFP#30 provide, and what is their resolution?
R5F2L3ACMNFP#30 provides 20 analog input channels with 10-bit resolution, including sample-and-hold circuitry and hardware-supported channel sweep mode. This enables precise acquisition from multiple thermistors, potentiometers, or current-sense resistors in appliance control systems without external multiplexers.
Can R5F2L3ACMNFP#30 drive a 1/8-duty LCD display, and what pins are required?
No, R5F2L3ACMNFP#30 does not support 1/8-duty LCD operation. Its LCD controller supports static, 1/2, 1/3, and 1/4 duty cycles only. For 1/8-duty displays, external segment drivers or a different MCU family (e.g., RL78/L12) would be required - the R5F2L3ACMNFP#30's maximum common output is 8 pins, limiting duty to 1/8 only if 8 commons were used, but the hardware lacks 1/8-duty timing logic.
What communication interfaces are available on R5F2L3ACMNFP#30 for connecting to external sensors or modules?
R5F2L3ACMNFP#30 integrates UART0/UART1/UART2 (with I²C mode), I²C bus (shared with SSU), LIN module (hardware-accelerated), and synchronous serial I/O. These support direct connection to temperature sensors (I²C), motor drivers (UART), and HVAC main boards (LIN), eliminating need for protocol translation ICs.
