Product details
Overview
R5F140FLAFP#30 from Renesas is a 512 KB flash, 32 KB RAM, 44-pin LQFP RL78/G13A 16-bit microcontroller operating at 1.6–5.5 V with ultra-low power consumption (47 µA/MHz typ.), real-time clock, 10-channel 8/10-bit ADC, and LIN-capable UART for industrial temperature range (−40 to +105°C). It targets appliance control and sensor interface applications requiring low-power operation and integrated timing.
For engineers reviewing the R5F140FLAFP#30 datasheet, R5F140FLAFP#30 pinout, R5F140FLAFP#30 application, or R5F140FLAFP#30 equivalent, key selection criteria include its 512 KB code flash capacity, 44-pin LQFP-0.8 mm package, −40 to +105°C industrial rating, on-chip debug support, and 10-channel analog input capability.
Technical Context
The R5F140FLAFP#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, 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 12-bit interval timer, watchdog timer, and real-time clock with calendar function and alarm.
Its peripheral set includes 8-channel 16-bit timer array, 4-channel CSI, 3-channel UART (one LIN-bus supported), 5-channel I²C/Simplified I²C, and DMA controller with 2 channels - all accessible via configurable I/O redirection through the PIOR register.
