4.0 kbyte data flash memory
— 16 data bits plus 6 syndrome ECC (Error Correction Code) bits allow single bit error correction and double-bit error
— Erase sector size 256 bytes
— Automated program and erase algorithm
— User margin level setting for reads
— Current gain control on amplitude output
— Signal with low harmonic distortion
— Low power
— Good noise immunity
— Eliminates need for external current limiting resistor
— Transconductance sized for optimum start-up margin for typical crystals
— No external components required
— Reference divider and multiplier allow large variety of clock rates
— Automatic bandwidth control mode for low-jitter operation
— Automatic frequency lock detector
— Configurable option to spread spectrum for reduced EMC radiation (frequency modulation)
— Reference clock sources:
Power-on reset (POR)
System reset generation
Illegal address detection with reset
Low-voltage detection with interrupt or reset
Real time interrupt (RTI)
Computer operating properly (COP) watchdog
— Configurable as window COP for enhanced failure detection
— Initialized out of reset using option bits located in flash memory
Clock monitor supervising the correct function of the oscillator
Configurable 8 or 16-bit data size
Full-duplex or single-wire bidirectional
Double-buffered transmit and receive
Master or slave mode
MSB-first or LSB-first shifting
Serial clock phase and polarity options
