Product details
Overview
R5F2138CCDFP#V0 from Renesas Electronics is a 16-bit R8C CPU core MCU 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 (50 ns min instruction time) across 1.8–5.5 V supply. It integrates dual 10-bit ADC (20 channels), dual 8-bit DAC, LIN hardware module, and six independent timer units-including 16-bit Timer RD with 6-pin complementary PWM-for motor control in consumer appliances.
For engineers reviewing the R5F2138CCDFP#V0 datasheet, R5F2138CCDFP#V0 pinout, R5F2138CCDFP#V0 application, or R5F2138CCDFP#V0 equivalent, this page delivers verified specifications, validated 80-pin LQFP package mapping, functional pin roles per Renesas R01DS0017EJ0110 Rev.1.10, and two confirmed alternative MCUs for embedded appliance and audio system designs.
Technical Context
The R5F2138CCDFP#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 supports four clock sources-XIN (up to 20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator-and features dedicated oscillation stop detection, voltage detection (VDD monitor with 3 levels), and background operation (BGO) for data flash reprogramming during runtime.
