Description This is standard ‘Watch’ or Real-Time-Clock (RTC) crystal. 32.768kHz means it is precisely half of a 16-bit counter. Start counting at 0x8000 (or 32768). When the counter rolls over from 65535 to 0, then you know that exactly one second has passed. Reset the interrupt, reset the counter, and start counting again! Rated at 12.5pF load capacitance, 35KΩ max (18K ohm typical) series resistance, and ±20ppm stability. Small cylinder 3T 3x8mm metal can package. Brief Data: In 3T 3x8mm metal can package High Reliability & Low Cost Unit Related Information: Detail Specification. Buy From… lelong.com.my logon.my
