Product details
Overview
R5F111PJAFB#50 from Renesas is an RL78/L1C 16-bit microcontroller without USB, featuring 256 KB flash, 16 KB RAM, integrated LCD controller/driver (56-segment/8-common), 12-bit A/D converter (13-channel), and ultra-low power operation down to 0.68 μA in RTC2+LVD mode - designed for battery-powered LCD-based consumer devices such as thermostats, blood glucose meters, and portable medical displays.
For engineers reviewing the R5F111PJAFB#50 datasheet, R5F111PJAFB#50 pinout, R5F111PJAFB#50 application, or R5F111PJAFB#50 equivalent, key selection criteria include its 100-pin LFQFP package, -40°C to +85°C temperature grade (A-grade), absence of USB peripheral, and support for internal voltage boosting LCD drive - critical for low-power, high-contrast segment display systems requiring long battery life and minimal external components.
Technical Context
The R5F111PJAFB#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs at 24 MHz to 30.5 μs at 32.768 kHz). It integrates a dedicated LCD controller supporting capacitor-split and internal boost methods, enabling direct drive of up to 448 segments (56 × 8) without external bias circuitry.
Its analog subsystem includes dual 8-bit D/A outputs, two comparators with selectable reference sources, and a 12-bit A/D converter operating at VDD = 2.4–3.6 V with internal 1.45 V reference and temperature sensor. Power management supports HALT, STOP, and SNOOZE modes, with on-chip LVD (12 programmable levels) and POR for robust operation across supply variations.
