Product details
Overview
R5F104BDGFP#10 from Renesas is a 32-bit RL78/G14 microcontroller with 32 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6–5.5 V at -40°C to +85°C (industrial grade D), delivering 44 DMIPS at 32 MHz for low-power embedded control in motor drives, sensor nodes, and industrial HMI.
For engineers reviewing the R5F104BDGFP#10 datasheet, R5F104BDGFP#10 pinout, R5F104BDGFP#10 application, or R5F104BDGFP#10 equivalent, key selection criteria include its 32-pin LQFP-0.8 mm package, integrated 10-bit ADC (20-channel), dual UART/LIN support, and ultra-low-power STOP mode (0.60 μA) with RTC+LVD retention.
Technical Context
The R5F104BDGFP#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). It integrates a Data Transfer Controller (DTC) with chain transfer and Event Link Controller (ELC) for peripheral event routing without CPU intervention.
Its mixed-signal peripherals include an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor, two 8-bit D/A channels, up to two comparators with window mode, and 16-bit Timer Array Unit (TAU) with 8 channels - all configurable via register-based peripheral I/O redirection (PIOR0/1).
