Low-power timing devices hit the consumer market

San Jose, Calif.—IDT (Integrated Device Technology Inc.) announced a family of real-time clock devices designed for use in consumer applications, such as set-top boxes, GPS devices, energy meters and MP3 players. In addition, the devices are well suited for use in the computing, medical and telecom markets.

The IDT real-time clocks are low-power clock/date devices with two programmable time-of-day alarms and a programmable square-wave output for applications requiring calendaring and time functionality. Address and data are transferred serially through an I²C bus. The devices have built-in power-sense circuits that detect power failures and automatically switch to the backup supply, maintaining time, date and alarm operation. The product family includes devices that offer extra 56 bytes of non-volatile SRAM.

The devices provide seconds, minutes, hours, day, date, month and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator.

The family offers packaging options that include an 8-pin mini small outline package (MSOP), an 8-pin small-outline integrated circuit (SOIC) or a 16-pin SOIC (surface-mount package with an integrated crystal).

Pricing: The IDT real-time clocks (1337, 1338 and 1339) range in price from $0.90 to $2.10 for 10,000 units.
Availability: Shipping in production.
