Microchip MIC7400 | Demoboard ADM00760

Description

MIC7400/1 Programming Board was designed to demonstrate the MIC7400/1 Power Management IC (PMIC) when programmed by a microcontroller, using an easy-to-understand interface. The board offers increased functionality by the addition of an on-board EEPROM and allows copy, store and also reprogram all the registers in the MIC7400/1 devices.
