Product details
Overview
R5F111PJGFB#30 from Renesas is an RL78/L1C 16-bit microcontroller without USB, featuring 256 KB flash, 16 KB RAM, integrated LCD controller/driver (up to 56 segments × 8 commons), 12-bit A/D converter (12-channel, 2.4–3.6 V range), and ultra-low power operation (0.68 μA in RTC2+LVD mode). It targets industrial LCD-based metering and control systems requiring high integration and extended battery life.
For engineers reviewing the R5F111PJGFB#30 datasheet, R5F111PJGFB#30 pinout, R5F111PJGFB#30 application, or R5F111PJGFB#30 equivalent, key selection criteria include its 100-pin LFQFP package, -40°C to +105°C industrial temperature grade, absence of USB peripheral, and segment LCD drive capability with internal voltage boosting.
Technical Context
The R5F111PJGFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.04167 μs min @ 24 MHz or 30.5 μs @ 32.768 kHz). It supports true low-power modes including HALT, STOP, and SNOOZE, with on-chip LVD (12 selectable levels) and POR.
