World's first serial EEPROM supporting ACR SIG
Microchip has announced the world's first serial EEPROM supporting the Advanced Communications Riser Special Interest Group (ACR SIG) specification.
As they operate within USB output-power limits, the MCP7381X charge-management controllers can be powered via the USB ports on most PCs.
The charge-enable input of the new devices provides a very simple interface for designers to use.
The MCP73811 has a digital input and selectable USB charge currents of either 100 or 500mA, whereas the MCP73812 offers a user-programmable charge current via an external resistor.
The new devices are ideal for a range of consumer electronic devices, such as rechargeable toys and low-cost MP3 players.
Samples of the new devices are available now.
