Product details
Overview
R5F104LJGFB#30 from Renesas is a 64-pin LFQFP, 0.5 mm pitch, industrial-grade (G) 16-bit RL78/G14 microcontroller with 192 KB flash, 8 KB data flash, 20 KB RAM, and operation from -40°C to +105°C. It delivers 44 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.60 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 12-bit RTC, 10-bit ADC (20 ch), and DTC/ELC peripherals for embedded control in constrained-power systems.
For engineers reviewing the R5F104LJGFB#30 datasheet, R5F104LJGFB#30 pinout, R5F104LJGFB#30 application, or R5F104LJGFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, 192 KB code flash with self-programming and flash shield window, dual-voltage operation (1.6–5.5 V), and integrated event-link controller for deterministic peripheral triggering in real-time sensor and actuator interfaces.
Technical Context
The R5F104LJGFB#30 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 multiply/divide/accumulate instructions and features a 1 MB address space with four banks of 8-bit general-purpose registers.
Its power management includes HALT, STOP, and SNOOZE modes, on-chip POR and LVD (14-level selectable), and a high-accuracy ±1.0% on-chip oscillator (1–64 MHz). Peripheral integration includes Event Link Controller (ELC) for 19–26 event sources, Data Transfer Controller (DTC), and background operation (BGO) for data flash rewriting while executing program code.
