Description:The RL78/I1C microcomputer integrates the functions required for the metrology of smart electricity meters. They include 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
Renesas provides a recommended PCB layout guide in their application note 'R5F10NMLDFB#50 PCB Layout Guidelines' (document number: R01AN0245EU0100). It includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
Renesas provides a Secure Boot and Firmware Encryption Guide (document number: R01AN0246EU0100) that outlines the steps to implement secure boot and firmware encryption using the R5F10NMLDFB#50's built-in security features, such as the Trusted Secure IP (TSIP) and the Advanced Encryption Standard (AES).
The R5F10NMLDFB#50's on-chip debug interface has limitations on the number of breakpoints, watchpoints, and trace buffer size. Refer to the 'R5F10NMLDFB#50 Debug Interface User's Manual' (document number: R01UM0247EU0100) for detailed information on the limitations and how to optimize debug performance.
Renesas provides a Power Management Guide (document number: R01AN0248EU0100) that outlines techniques for optimizing power consumption, including clock gating, voltage scaling, and sleep modes.
