Overview
R5F1016EASP#50 from Renesas is a 20-pin, 64 KB flash, 4 KB data flash, 3 KB RAM RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), 1.6–5.5 V supply, and integrated 16-bit timers, 10-bit ADC (6 channels), UART/SPI/I²C interfaces - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F1016EASP#50 datasheet, R5F1016EASP#50 pinout, R5F1016EASP#50 application, or R5F1016EASP#50 equivalent, key selection criteria include its 20-pin LSSOP package, absence of on-chip data flash (per "101" series designation), -40°C to +85°C industrial temperature grade, and support for SNOOZE mode wake-up via serial interface or timer events.
Technical Context
The R5F1016EASP#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer driven by dedicated low-speed on-chip oscillator.
Its peripheral set includes up to 6-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, dual UART/SPI/I²C serial interfaces (CSI, UART/LIN, I²C), DMA controller (2 channels), and multiplier/divider unit supporting 16×16→32-bit and 32÷32→32-bit operations - all operating within 1.6–5.5 V supply range.
