Linear Technology has launched a new dual Hot Swap controller. Designed to protect boards with multiple load supply voltages ranging from 2.9V to 29V, the LTC4222 enables safe board insertion and removal from a live, two-supply backplane by controlling external N-channel MOSFETs to limit the inrush currents during power up. When a board is plugged into a backplane, inrush currents can be large enough to create a glitch on the load supply, causing other boards on the bus to malfunction....
Microcontrollers for M2M communication modules
Atmel has announced the availability of its new AT90M family. Designed for Machine-to-Machine (M2M) modules, these new models provide wireless connectivity to a range of equipment that communicates without human intervention by using GSM or UMTS networks. Based on the 8bit/16bit RISC core allowing single cycle instruction execution, the first device, AT90M25672RU, embeds 72Kbytes of EEPROM data memory, 6Kbytes of RAM and 256Kbytes of ROM program memory, providing high density and...
