1 / 148 page  R01DS0502EJ0110 Rev.1.10 Page 1 of 145 Oct 31, 2025 RL78/L23 RENESAS MCU On-chip LCD controller/driver, true low-power platform, 50-µA/MHz operating current, 330-nA data retention current for 4 KB of RAM, up to 512-KB code flash memory and 32-KB RAM, up to 36 capacitive touch sensors, from 44 to 100 pins, 1.6-5.5 V Datasheet 1. Outline 1.1 Features Ultra-low power consumption technology •VDD = single power supply voltage of 1.6 to 5.5 V •HALT mode • STOP mode High-speed wakeup from the STOP mode is possible. • SNOOZE mode RL78 CPU core • CISC architecture with 3-stage pipeline • Minimum instruction execution time: Can be changed from high speed (0.03125 µs @ 32 MHz operation with the high-speed on-chip oscillator clock) to ultra-low speed (30.5 µs @ 32.768 kHz operation with the subsystem clock) • Multiply/divide/multiply & accumulate instructions are supported. • Address space: 1 MB • General-purpose registers: (8-bit register × 8) × 4 banks • On-chip RAM: 16 to 32 KB Code flash memory • Code flash memory: 64 to 128 KB (single bank) 256 KB (128 KB × 2 banks or a single 256-KB bank) 512 KB (256 KB × 2 banks or a single 512-KB bank) • Block size: 2 KB • Prohibition of block erase and rewriting (security function) • On-chip debugging • Self-programming (with boot swapping and flash shield window) • Bank programming: Enables updating of the program in one bank while the user program is running from the other bank. Data flash memory • Data flash memory: 8 KB • Background operation (BGO): Instructions can be executed from the program memory while rewriting the data flash memory. • Number of rewrites: 1,000,000 times (typ.) High-speed on-chip oscillator • Select from 64 MHz, 48 MHz, 32 MHz, 24 MHz, 16 MHz, 12 MHz, 8 MHz, 6 MHz, 4 MHz, 3 MHz, 2 MHz, or 1 MHz • High accuracy: ±1.0% (VDD = 1.6 to 5.5 V, TA = -40 to +105°C) Middle-speed on-chip oscillator • Select from 4 MHz, 2 MHz, or 1 MHz (with adjustability) Low-speed on-chip oscillator • 32.768 kHz (typ.) (with adjustability) Operating ambient temperature •TA = -40 to +105°C (3C: Industrial applications) Power management and reset function • On-chip power-on-reset (POR) circuit • On-chip voltage detectors (LVD0 and LVD1) Data transfer controller (DTC) • Transfer modes: Normal transfer mode, repeat transfer mode, block transfer mode • Activation sources: Activated by interrupt sources. • Chain transfer function R01DS0502EJ0110 Rev.1.10 Oct 31, 2025 |
