Product details
Overview
R5F1017EDNA#U0 from Renesas is a 24-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, 2 KB RAM, 16 MHz max CPU frequency, and industrial-grade -40°C to +85°C operation. It integrates 10-bit ADC (12 channels), RTC, UART, I²C, CSI, 16-bit timers, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for embedded control in battery-powered and space-constrained applications.
For engineers reviewing the R5F1017EDNA#U0 datasheet, R5F1017EDNA#U0 pinout, R5F1017EDNA#U0 application, or R5F1017EDNA#U0 equivalent, key selection criteria include its 24-pin HWQFN-0.5 mm pitch package, absence of on-chip data flash programming capability (data flash not mounted), support for 1.6–5.5 V supply, and suitability for cost-sensitive industrial sensor nodes and motor control interfaces requiring deterministic real-time response and low active/idle power.
Technical Context
The R5F1017EDNA#U0 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 subsystem clock). It features a dedicated low-speed on-chip oscillator for watchdog and RTC operation independent of main clock domain.
Its peripheral set includes 12-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, dual UART channels (one supporting LIN-bus), up to 10 I²C/Simplified I²C interfaces, and 16-bit timer array with interval timer and real-time clock calendar function (99-year range, alarm, correction).
