RL78/I1C Block Diagram
Description
The RL78/I1C microcontroller integrates functions required for the metrology of smart electricity meters. It includes 24-bit ΔΣ A/D converters, 32-bit multiply-accumulator, independent power supply real-time clock, segment LCD driver supporting up to 8 com, and AES hardware engine that supports the DLMS standard. For single-phase two-wire meters, single-phase three-wire meters, and three-phase three-wire meters, 24-bit ΔΣ A/D converters (Max 4ch) are used for current and voltage sensing to achieve highly accurate power metrology.
Moreover, three-phase four-wire meters can be supported by the 100-pin QFP products, with ΔΣ A/D converters that are used for current sensing and a successive approximation A/D converter unit that is used for voltage sensing.
In addition, the products equipped with 512KB flash memory can also use the code flash area as two partitions, that is 256KB x 2 banks, independently. Thanks to the bank programming function in dual-bank mode and bank swapping, the system can update the firmware without stopping the metrology operation throughout the new firmware downloading and even the bank swapping period.

- Application NoteThis application note describes the specifications of the boot firmware in RL78 microcontrollers. An RL78 microcontroller has embedded boot firmware to control rewriting of its flash memory. The firmware controls rewriting of the contents of on-chip flash memory through the transmission and reception of commands between the programmer and RL78 microcontroller via serial communications.
- Application NoteAI-generated Summary: The RL78 Family SHA Hash Function Library includes various source files, sample programs, and documentation to support SHA-1 and SHA-256 hash functions. It provides API functions to generate SHA-1 and SHA-256 hash digests, with SHA-256 support enhanced when combined with the RL78/G24 FAA accelerator. The library supports specific compiler environments and requires building designated source files depending on the API used. The FAA accelerator improves SHA processing speed and supports only SHA-256 with certain compilers.Related Files:
- Application NoteAI-generated Summary: The document explains how to integrate and use IAR Systems compilers within the e² studio development environment for Renesas microcontrollers. It details the installation of IAR Embedded Workbench and IAR Eclipse plugins, project creation, build configuration, and build execution using IAR compilers. The guide focuses on the RA family with the IAR ARM compiler but applies similarly to other Renesas devices. It also recommends using standalone Flexible Software Package configurators for RA and RZ families to enhance development. The environment setup assumes Windows 10 64-bit, e² studio 2024-07, and IAR tools installed.
