Description
SPI Data In
SPI Data Clock
Chip Select Input - Selects the chip for an SPI data transaction. The pin must be pulled
‘low’ for a 16-bit read or write function. See Figure 4 for timing specifications.
Switch or Push Button Input 1 with Internal pull-up resistor
Switch or Push Button Input 2 with Internal pull-up resistor
Switch or Push Button Input 3 with Internal pull-up resistor
Switch or Push Button Input 4 with Internal pull-up resistor
SPI Data Out
Xtal - Connects to a 10MHz series crystal or an external oscillator reference.
contains an integrated load capacitor (See Configuration Register) in order to minimize
the external component count. The crystal is used as the reference for the PLL, which
generates the local oscillator frequency. The accuracy requirements for production
tolerance, temperature drift and aging can be determined from the maximum allowable
local oscillator frequency error. Whenever a low frequency error is essential for the
application, it is possible to “pull” the crystal to the accurate frequency by changing the
load capacitor value.
Ext Ref – An external reference, such as an oscillator, may be connected as a reference
source. Connect through a .01uF capacitor.
System Ground
Mode Select – Connect to GND for EEPROM Mode.
RF Diff I/O
RF Diff I/O
Low Battery Detect – When the battery voltage falls below the programmed level this
output goes “low”. The voltage level is programmable through the Battery Detect
Threshold Register.
Supply Voltage
Not used. Tie to VDD or GND
