RL78/G23 Ultra Low-Power MCU

Renesas’ MCU offers increased ROM/RAM size and is available in a variety of package sizes

Image of Renesas RL78/G23 Ultra-Low Power MCURenesas' easy-to-use RL78/G23 ultra low-power 16-bit MCU reflects the specific needs of IoT endpoints and applications that require low-power operation. RL78/G23 solves design challenges by addressing key requirements, such as low-power consumption, larger ROM size, serial channel count increase, built-in touch interface, and added security functions. These features and expanded functions are implemented while maintaining compatibility with existing RL78 products, so users will be able to easily migrate from current RL78 designs.

Building on the popular RL78/G13 family, RL78/G23 offers increased ROM/RAM size (maximum 512 KB / 32 KB to 768 KB / 48 KB) and equips functions such as SMS and ELCL, touch keys, remote control receiver circuit, D/A and comparator, TRNG, customer ID and unique ID as security functions, output current selectable port, and 40 mA output port are implemented.

Features
  • RL78-S3 CPU core up to 32 MHz
  • Flash: 768 KB maximum
  • SRAM: 48 KB maximum
  • Variety of packages: up to 128-pin
  • Industry's highest accuracy level: ±1% HOCO
  • Capacitive touch
  • Ultra low-power on commonly used peripherals: RL78/G23 achieves number 1 ULP-PP score worldwide, surpassing RL78/I1D
  • Compatibility with RL78/G13
  • Snooze mode sequencer (SMS) achieves low power consumption
  • Logic and event link controller (ELCL): upgradeable extended functions
Applications
  • Standard general-purpose MCUs
  • IoT devices
  • Battery operated equipment
  • Home appliances
  • Industrial equipment
