Product details
Overview
R5F100LKGFB#30 from Renesas is a 64-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 384 KB flash, 8 KB data flash, 24 KB RAM, and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART, I²C, CSI, RTC, and low-power modes down to 0.57 μA. It targets battery-powered industrial sensors and smart metering systems requiring long runtime and robust timing.
For engineers reviewing the R5F100LKGFB#30 datasheet, R5F100LKGFB#30 pinout, R5F100LKGFB#30 application, or R5F100LKGFB#30 equivalent, key selection criteria include its 384 KB code flash capacity, 64-pin LFQFP-0.5 mm pitch package, -40°C to +105°C industrial temperature grade (G suffix), real-time clock with calendar function, and support for background data flash rewriting during program execution.
Technical Context
The R5F100LKGFB#30 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a 12-bit interval timer, one real-time clock with calendar/alarm/correction, and a watchdog timer operating on a dedicated low-speed oscillator.
Its memory subsystem includes 384 KB on-chip code flash (1 KB block size, security-protected erase/write), 8 KB data flash with background operation (BGO) and 1M rewrite cycles, and 24 KB RAM. Power management features HALT, STOP, and SNOOZE modes, achieving 66 μA/MHz active current and 0.57 μA in RTC+LVD-only operation.
