RTC Sets Power-Efficiency Benchmark

Announced as the industry’s best low-power performance real-time clock with an SPI bus interface, the PCF2123 operates at a current of less than 100 nA (0.15mW) from a 1.5V power supply. Targeting compact designs, the device comes in a 3 mm x 3 mm x 1 mm leadless package. Features include a freely programmable alarm and timer function that gives users the option to generate a wake-up signal on an interrupt pin and a programmable offset register that allows fine-tuning of the clock and frequency adjustment. Sample pricing is $0.55 each. For further information, call NXP SEMICONDUCTORS, USA. (800) 447-1500.
