Overview
R5F2138CMNFP#V0 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 128 KB flash program ROM, 10 KB data flash (4 × 1 KB blocks), and 2.5 KB RAM, operating at up to 20 MHz (VCC = 2.7–5.5 V) for real-time control in consumer appliance motor drives and audio subsystems.
For engineers reviewing the R5F2138CMNFP#V0 datasheet, R5F2138CMNFP#V0 pinout, R5F2138CMNFP#V0 application, or R5F2138CMNFP#V0 equivalent, key selection criteria include its 80-pin LQFP package, integrated LIN hardware module (using Timer RA + UART0), 20-channel 10-bit ADC with sweep mode, dual 8-bit DAC outputs, and background operation (BGO) support for data flash reprogramming during runtime.
Technical Context
The R5F2138CMNFP#V0 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory map spans 1 Mbyte (00000h–FFFFFh), with fixed interrupt vector table at 0FFDCh–0FFFFh and data flash at 03000h–03FFFh.
It integrates six independent timer modules (RA–RG), including Timer RD with complementary PWM for three-phase motor control, and supports multiple clock sources: external XIN (up to 20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator - all with oscillation stop detection and selectable frequency dividers (1/2/4/8/16).

The R5F2138CMNFP#V0 supports a maximum operating frequency of 20 MHz when powered at VCC = 2.7–5.5 V using the XIN clock source. At reduced supply voltages (1.8–5.5 V), the maximum frequency is 5 MHz. The high-speed on-chip oscillator is adjustable and usable as an alternative clock source without external components.
Does the R5F2138CMNFP#V0 support hardware LIN communication?
Yes, the R5F2138CMNFP#V0 includes a dedicated hardware LIN module compliant with LIN 2.0/2.1 standards, implemented using Timer RA and UART0. This offloads protocol handling from the CPU, ensures precise timing for break field and sync field generation, and supports automatic checksum calculation and error detection without software intervention.
How many analog input channels does the R5F2138CMNFP#V0 have, and what is their resolution?
The R5F2138CMNFP#V0 features a 10-bit successive approximation A/D converter with 20 analog input channels (AN0–AN19). It supports sample-and-hold functionality and sweep mode for automatic sequential conversion across selected channels, reducing CPU overhead during multi-sensor monitoring tasks.
What is the purpose of the data flash memory in the R5F2138CMNFP#V0?
The R5F2138CMNFP#V0 includes 4 × 1 KB blocks (10 KB total) of data flash memory with background operation (BGO) capability. This allows firmware to read from or write to data flash while executing application code - enabling safe storage of calibration data, device configuration, usage logs, or field-upgradable parameters without interrupting real-time control functions.
Is the R5F2138CMNFP#V0 pin-compatible with other members of the R8C/38M Group?
Yes, all R8C/38M Group MCUs, including R5F2138CMNFP#V0, share the identical 80-pin LQFP (PLQP0080KB-A) package and fully compatible pinout. Memory size, data flash capacity, and temperature grade vary across part numbers, but I/O assignment, peripheral mapping, and electrical characteristics remain consistent - enabling hardware reuse across firmware variants.
