CMOS Serial Real-Time Clock With RAM  
and Power Sense/Control  
The CDP68HC68T1 Real-Time Clock provides a  
Features  
• SPI (Serial Peripheral Interface)  
• Full Clock Features  
time/calendar function, a 32 byte static RAM, and a 3 wire  
Serial Peripheral Interface (SPI Bus). The primary function of  
the clock is to divide down a frequency input that can be  
supplied by the on-board oscillator in conjunction with an  
external crystal or by an external clock source. The internal  
oscillator can operate with a 32kHz, 1MHz, 2MHz, or 4MHz  
crystal. An external clock source with a 32kHz, 1MHz, 2MHz,  
4MHz, 50Hz or 60Hz frequency can be used to drive the  
CDP68HC68T1. The time registers hold seconds, minutes,  
and hours, while the calendar registers hold day-of-week,  
date, month, and year information. The data is stored in BCD  
format. In addition, 12 or 24 hour operation can be selected.  
In 12 hour mode, an AM/PM indicator is provided. The T1  
has a programmable output which can provide one of seven  
outputs for use elsewhere in the system.  
- Seconds, Minutes, Hours (12/24, AM/PM), Day of  
Week, Date, Month, Year (0-99), Automatic Leap Year  
• 32 Word x 8-Bit RAM  
• Seconds, Minutes, Hours Alarm  
• Automatic Power Loss Detection  
• Low Minimum Standby (Timekeeping) Voltage . . . . . 2.2V  
• Selectable Crystal or 50/60Hz Line Input  
• Buffered Clock Output  
• Battery Input Pin that Powers Oscillator and also  
Connects to V  
Pin When Power Fails  
DD  
• Three Independent Interrupt Modes  
- Alarm  
- Periodic  
- Power-Down Sense  
Computer handshaking is controlled with a “wired-OR” interrupt  
output. The interrupt can be programmed to provide a signal as  
the result of: 1) an alarm programmed to occur at a  
• Pb-Free Plus Anneal Available (RoHS Compliant)  
predetermined combination of seconds, minutes, and hours; 2)  
one of 15 periodic interrupts ranging from sub-second to once  
per day frequency; 3) a power fail detect. The PSE output and  
the V  
input are used for external power control. The CPUR  
SYS  
output is available to reset the processor under power-down  
conditions. CPUR is enabled under software control and can  
also be activated via the CDP68HC68T1’s watchdog. If  
enabled, the watchdog requires a periodic toggle of the CE pin  
without a serial transfer.
