Product details
Overview
R5F104BADFP#X0 from Renesas Electronics is a 32-pin LQFP-32, 0.8 mm pitch, industrial-grade (D) 16-bit RL78/G14 microcontroller with 64 KB flash, 5.5 KB RAM, and 4 KB data flash. It operates from 1.6–5.5 V, delivers 44 DMIPS at 32 MHz, and supports ultra-low-power modes (66 μA/MHz active, 0.60 μA RTC+LVD). It targets battery-powered industrial sensors and smart metering interfaces requiring integrated analog peripherals and secure firmware updates.
For engineers reviewing the R5F104BADFP#X0 datasheet, R5F104BADFP#X0 pinout, R5F104BADFP#X0 application, or R5F104BADFP#X0 equivalent, key selection criteria include its 32-pin LQFP package, 64 KB code flash with self-programming and boot swap, dual UART/LIN support, 10-bit 8-channel ADC with internal reference, and industrial temperature range (−40°C to +85°C).
Technical Context
The R5F104BADFP#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a Data Transfer Controller (DTC) for autonomous memory transfers and an Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.
Its analog subsystem includes an 8/10-bit ADC with up to 8 input channels, internal 1.45 V reference, and temperature sensor; an 8-bit DAC with real-time output capability; and up to two comparators configurable in high-speed, low-speed, or window mode. Serial connectivity comprises three UART/LIN channels, four I²C interfaces, and up to eight CSI (SPI-compatible) channels.
