Microchip Technology ADM00760

Overview

ADM00760 from Microchip Technology is a dedicated programming and evaluation board for the MIC7400 and MIC7400/1 Power Management ICs, supporting register-level configuration, EEPROM-based parameter backup/reload, and device cloning via MIC2221 interface. It operates from CR2032 coin cell, USB, or external 5V supply and features live Power-Good LEDs for all six outputs.

For engineers reviewing the ADM00760 datasheet, ADM00760 pinout, ADM00760 application, or ADM00760 equivalent, this board enables rapid validation of MIC7400/1 PMIC behavior in multi-rail power sequencing, battery-backed configuration storage, GUI-driven cloning, and LCD-guided register programming workflows.

Technical Context

The ADM00760 implements a hardware abstraction layer between host microcontrollers and MIC7400/1 PMICs using the MIC2221 serial interface IC. It integrates a 2K EEPROM (24AA02E48) for persistent storage of register maps and supports eight distinct operational modes including clone, store, restore, and interactive debug.

Power delivery is managed through dual-path regulation: one path conditions USB/5V input for board logic and MIC7400/1 VDD, while the second path supplies the CR2032 coin cell directly to the MIC7400/1 VBAT rail-enabling real-time battery-backed configuration retention during main power loss.

FAQ

What is the primary function of the ADM00760?

The ADM00760 is a dedicated programming and evaluation board for the MIC7400 and MIC7401 PMICs. It enables register-level configuration, EEPROM-based parameter backup and reload, and device cloning via the MIC2221 interface. The ADM00760 supports standalone operation using a CR2032 coin cell, USB, or external 5V supply, and includes an LCD interface and Power-Good LEDs for real-time feedback.

Does the ADM00760 require a PC to operate?

No, the ADM00760 does not require a PC for basic operation. Its integrated character LCD provides menu-driven, text-based interaction for configuring, storing, and restoring MIC7400/1 register settings. However, PC connectivity via the MIC2221 interface is required for advanced functions like GUI-driven cloning and full register editing. The ADM00760 remains fully functional offline for field validation and battery-backed configuration tasks.

Which PMIC devices are supported by the ADM00760?

The ADM00760 is explicitly designed for the MIC7400 and MIC7401 Power Management ICs. It supports full register access, EEPROM-based parameter storage, and device cloning for both variants. The board's firmware, hardware interface, and EEPROM mapping are validated only for these two parts-not for other MIC7xxx family members or unrelated PMICs.

How does the on-board EEPROM function with the ADM00760?

The ADM00760 integrates a 2 Kbit 24AA02E48 EEPROM to store the complete register map of the connected MIC7400 or MIC7401. This allows users to back up current configurations, restore them later, or clone settings across multiple devices. The EEPROM retains data during power loss, enabling reliable configuration persistence even when operating from the CR2032 coin cell. The ADM00760 firmware manages read/write cycles directly without host intervention.

Can the ADM00760 be used for production programming?

The ADM00760 is intended for development, evaluation, and prototyping-not high-volume production programming. While it supports reliable register configuration and cloning, its manual interface, single-device connection, and lack of automated test reporting make it unsuitable for production line use. For production, Microchip recommends dedicated programmers or custom host-controlled solutions interfacing with the MIC7400/1 I²C registers. The ADM00760 remains essential for validating those production flows.
