Product details
Overview
R5F100MJAFB#50 from Renesas is an RL78/G13 16-bit general-purpose microcontroller with 192 KB flash memory, 8 KB data flash, and 16 KB RAM, operating at up to 32 MHz (41 DMIPS), supporting ultra-low-power modes (0.57 μA RTC+LVD), 10-bit A/D converter (26 channels), and integrated real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100MJAFB#50 datasheet, R5F100MJAFB#50 pinout, R5F100MJAFB#50 application, or R5F100MJAFB#50 equivalent, key selection criteria include its LFQFP-80 package with 0.5-mm pitch, -40°C to +105°C industrial temperature grade (G), on-chip debug support, and BGO-capable data flash for firmware-over-the-air updates without halting execution.
Technical Context
The R5F100MJAFB#50 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 subsystem clock), and features a unified 1 MB address space with four register banks of eight 8-bit registers each.
It integrates dual power management domains: a main VDD supply (1.6–5.5 V) and dedicated low-speed oscillator for watchdog and RTC operation, plus configurable LVD with 14 interrupt/reset threshold levels and hardware-accelerated 16×16/32÷32 arithmetic units for deterministic control-loop timing.
