Product details
Overview
R5F100LEAFB#30 from Renesas is a 64-pin LFQFP (0.5 mm pitch), 512 KB flash, 8 KB data flash, 32 KB RAM RL78/G13 16-bit microcontroller with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), 1.6–5.5 V operation, and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and DMA - deployed in industrial motor control and smart sensor nodes.
For engineers reviewing the R5F100LEAFB#30 datasheet, R5F100LEAFB#30 pinout, R5F100LEAFB#30 application, or R5F100LEAFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, 512 KB code flash with self-programming and flash shield window, -40°C to +85°C industrial temperature grade (D), and support for background data flash rewriting (BGO) at VDD = 1.8–5.5 V.
Technical Context
The R5F100LEAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.03125 μs @ 32 MHz high-speed oscillator to 30.5 μs @ 32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer operating on a dedicated low-speed on-chip oscillator.
Peripherals include up to 16 channels of 16-bit timer, 3–10 I²C/Simplified I²C interfaces, 2–4 UART/LIN channels, 2–8 CSI (SPI-compatible) channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all operating across the full 1.6–5.5 V supply range and qualified for industrial ambient temperatures (-40°C to +85°C).
