Non-Volatile Data Storage
The non-volatile data storage (NVDS) uses a hybrid hardware/software scheme to imple-
ment a byte programmable data memory and is capable of over 100,000 write cycles.
Internal Precision Oscillator
The internal precision oscillator (IPO) is a trimmable clock source that requires no exter-
nal components.
Crystal Oscillator
The crystal oscillator circuit provides highly accurate clock frequencies with the use of an
external crystal, ceramic resonator or RC network.
10-Bit Analog-to-Digital Converter
The optional analog-to-digital converter (ADC) converts an analog input signal to a 10-bit
binary number. The ADC accepts inputs from eight different analog input pins in both sin-
gle-ended and differential modes. The ADC also features a unity gain buffer when high
input impedance is required.
Low-Power Operational Amplifier
The optional low-power operational amplifier (LPO) is a general-purpose amplifier prima-
rily targeted for current sense applications. The LPO output may be routed internally to the
ADC or externally to a pin.
Analog Comparator
The analog comparator compares the signal at an input pin with either an internal pro-
grammable voltage reference or a second input pin. The comparator output can be used to
drive either an output pin or to generate an interrupt.
Temperature Sensor
The optional Temperature Sensor produces an analog output proportional to the device
temperature. This signal can be sent to either the ADC or the analog comparator.
