Microchip Technology introduced their MCP794XX stand-alone I2C Real-Time Clock/Calendar (RTCC) family. The MCP794XX features on-chip EEPROM and SRAM, digital trimming for time-of-day calibration, battery-switchover, user-lockable section of EEPROM, 64-bit reprogrammable unique ID that can be factory-programmed with a MAC address. All six MCP794XX RTCC devices are available in 8-pin MSOP, SOIC, TSSOP and TDFN packages. The MCP79400 is priced at $0.64 each; the MCP79401, MCP79402 and MCP79410 at $0.70 each; and the MCP79411 and MCP79412 at $0.76 each, all in 10,000-unit quantities. The devices are ideal for smart-energy (thermostats, power meters and commercial refrigeration), home-appliance (stoves, dishwashers and microwave ovens), automotive (dashboard controls and car radios), and consumer-electronic markets (office equipment, irrigation controls and video systems).
Analog Devices, Inc. (ADI) announced the AD9553 clock generator and ADCLK944 high-speed clock fanout buffer. The new clock products improve performance and reduce programming and design complexity in synchronous optical networks and wireless base stations. The AD9553 (5 mm x 5 mm, 32-lead LFCSP) and ADCLK944 (3 mm x3 mm, 16-lead LFCSP) are sampling now for $5.10 and $6.00, respectively.
IDT (Integrated Device Technology) introduced the 5P49EE801, 5P49EE802, 5P49EE601, 5P49EE602, and 5P49EE502 VersaClock LP devices. The VersaClock low power devices are available in several package options, including 20-pin and 24-pin QFN. The new timing devices are sampling to qualified customers and range in price from $0.80 to $1.25 for 10,000 units. Evaluation boards are available for qualified customers. The VersaClock low power (LP) devices are programmable clock generators designed to reduce power consumption and optimize board layout in battery-operated consumer applications.
