Product details
Overview
R5F100LJABG#V0 from Renesas is a 64-pin LQFP-packaged RL78/G13 16-bit microcontroller with 192 KB flash, 8 KB data flash, 16 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - used in smart metering, industrial HMI, and battery-powered sensor nodes.
For engineers reviewing the R5F100LJABG#V0 datasheet, R5F100LJABG#V0 pinout, R5F100LJABG#V0 application, or R5F100LJABG#V0 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, G-grade temperature range (−40°C to +105°C), integrated data flash with 1M rewrite cycles, low-power STOP/HALT/SNOOZE modes, and RL78 CPU core with 1 MB address space and hardware multiplier.
Technical Context
The R5F100LJABG#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @32 MHz to 30.5 μs @32.768 kHz). It supports dual-clock domains: high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy) and subsystem clock for ultra-low-power peripherals.
Its memory subsystem includes 192 KB code flash (1 KB block size, security lock), 8 KB background-operable data flash (BGO enabled), and 16 KB SRAM - with flash library RAM usage starting at FAF00H. Peripheral integration includes 3× I²C, 4× UART/LIN, 8× CSI, 16× 16-bit timers, RTC with calendar/alarm, and 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor.
