RL78/G24

RENESAS MCU

Nov 1, 2023

High-performance with 48-MHz CPU operation on true low-power platform, 50-µA/MHz operating current, flexible

application accelerator (FAA), enhanced timers and analog functions for motor control, digital power supply, and lighting

applications, providing PMBus/SMBus, and DALI-2 communications, from 20 to 64 pins, 1.6- to 5.5-V operation

1. Outline

1.1

Features

• A 32-byte shared memory is included for sharing

of data by the RL78 CPU and FAA core.

Ultra-low power consumption technology

• VDD = single power supply voltage of 1.6 to 5.5 V

• HALT mode

Divider

• STOP mode

• 32-bit ÷ 32-bit = 32-bit unsigned

• High-speed wakeup from the STOP mode is

possible.

Code flash memory

• SNOOZE mode

• 64 or 128 Kbytes

• Block size: 2 Kbytes

RL78 CPU core

• Security function: Prohibition of block erase and

rewriting

• CISC architecture with 3-stage pipeline

• The minimum instruction execution time can be

changed from high to ultra-low speed.

– High speed: 0.02083 µs at 48 MHz operation

with the high-speed on-chip oscillator clock or

the PLL clock

• On-chip debugging

• Self-programming with boot swapping and flash

shield window

Data flash memory

– Ultra-low speed: 30.5 µs at 32.768 kHz

operation with the subsystem clock

• Multiply/divide/multiply & accumulate instructions

are supported.

• 4 Kbytes

• 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.)

• Address space: 1 Mbyte

• General-purpose registers: (8-bit register × 8) × 4

banks

High-speed on-chip oscillator

• Selectable from among 64 MHz, 48 MHz, 32 MHz,

24 MHz, 16 MHz, 12 MHz, 8 MHz, 6 MHz, 4 MHz,

3 MHz, 2 MHz, and 1 MHz

• On-chip RAM: 12 Kbytes

FAA core

• Multiplication: 32-bit signed × 32-bit signed →

32-bit signed

• High accuracy:

±1.0% (VDD = 1.8 to 5.5 V, TA = –20 to

+85°C)

• Results of 64-bit multiplication can be right-shifted

by a desired number of bits.

• Addition: 32-bit signed + 32-bit signed → 32-bit

signed (internally calculated with 33-bit precision)

• Subtraction: 32-bit signed - 32-bit signed → 32-bit

signed (internally calculated with 33-bit precision)

• Limit operation: Operation parameter registers (33

bits × 4) in which upper and lower limits can be

set.

Middle-speed on-chip oscillator

• Selectable from among 4 MHz, 2 MHz, and 1 MHz

with adjustability

Low-speed on-chip oscillator

• 32.768 kHz (typ.) with adjustability

• Operation parameter registers (32 bits × 6)

• Address pointer registers (12 bits × 6)

• On-chip code RAM: 4 Kbytes

Operating ambient temperature

• TA = –40 to +85°C (2D: Consumer applications)

• TA = –40 to +105°C (3C: Industrial applications)

• TA = –40 to +125°C (4C: Industrial applications)

• On-chip data RAM: 2 Kbytes

• Multiple interrupts available
