CDP68HC68T1
CMOS Serial Real-Time Clock With RAM
and Power Sense/Control
The CDP68HC68T1 Real-Time Clock provides a
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.
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 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 VSYS input are
used for external power control. The CPUR 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.
