Product details
Overview
R5F100MLAFB#30 from Renesas is an RL78/G13 80-pin, 512 KB flash, 32 KB RAM, 8 KB data flash microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V supply, and integrated 32 MHz high-accuracy on-chip oscillator (±1.0%). It targets battery-powered industrial control, sensor nodes, and smart appliances requiring real-time clock, 26-channel 10-bit ADC, and LIN/UART/I²C/SPI interfaces.
For engineers reviewing the R5F100MLAFB#30 datasheet, R5F100MLAFB#30 pinout, R5F100MLAFB#30 application, or R5F100MLAFB#30 equivalent, key selection considerations include its LFQFP-80 (12×12 mm, 0.5 mm pitch) package, -40°C to +105°C industrial-grade temperature range (G-grade), 16-channel 16-bit timer, and background data flash rewrite capability supporting 1M write cycles.
Technical Context
The R5F100MLAFB#30 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline and variable instruction timing (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It integrates a DMA controller (4 channels), 16×16-bit multiplier, 32-bit divider, and BCD correction circuit for embedded math and display support.
Its power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and dual-clock system (main high-speed oscillator + subsystem low-speed oscillator). The device supports self-programming with boot swap and flash shield window functions for secure firmware updates.
