Maxim 71M6541D/F/G and 71M6542F/G IC Datasheet
The Maxim 71M6541D/F/G and 71M6542F/G series are fourth‑generation, high‑integration single‑phase smart‑grid ICs that combine an 8051‑compatible MPU, low‑power RTC, LCD driver and multiple analog front‑end functions. They support SPI, UART and other interfaces, offering configurable power modes and on‑chip memory.
The document provides detailed functional descriptions, pin configurations for 64‑pin and 100‑pin LQFP packages, memory maps, register tables, timing diagrams and revision history, enabling designers to integrate the devices into smart‑meter and grid applications. This manual is written in Japanese.
