It tracks time in both 12-hour and 24-hour formats with a YY-MM-DD-dd date format, and includes a programmable alarm and 8 bytes of NVSRAM for storing configuration or event flags that survive a power loss. ## Timekeeping current and battery-life consideration Timekeeping current is 8 µA to 15 µA at 2 V to 5 V — at the low end, a 220 mAh CR2032 coin cell would theoretically power the RTC for over 1.5 years before depletion, though real battery life depends on the alarm duty cycle and I2C bus activity. ## Package and board integration Housed in an 8-SOIC package (3.90 mm width, 0.154\" pitch), it fits standard surface-mount assembly lines and reflow profiles. The supplier device package is 8-SO, consistent with the SOIC-8 footprint common on two-layer boards. Available in Tape & Reel (TR) or Cut Tape (CT) — the reel option suits automated pick-and-place for volume production; cut tape works for prototype runs. ## Lifecycle and compliance status RoHS3 compliant (2011/65/EU + 2015/863), with no exemptions — no lead, mercury, or other restricted substances in the package or die attach.","metaTitle":"NXP PCF8593T/1,118 RTC Clock/Calendar, I2C, 8-SOIC","metaDescription":"NXP PCF8593T/1,118 RTC with I2C interface, 2.5V-6V supply, -40°C to 85°C, 8B NVSRAM, alarm.
