Philips Semiconductors
Low power, low price, low pin count (14 pin)
microcontroller with 1 kbyte OTP
Preliminary data
P87LPC760
THE OSCILLATOR MUST BE CONFIGURED IN ONE OF
THE FOLLOWING MODES:
– LOW FREQUENCY CRYSTAL
– MEDIUM FREQUENCY CRYSTAL
– HIGH FREQUENCY CRYSTAL
QUARTZ CRYSTAL OR
CERAMIC RESONATOR
CAPACITOR VALUES MAY BE OPTIMIZED FOR
DIFFERENT OSCILLATOR FREQUENCIES (SEE TEXT)
A SERIES RESISTOR MAY BE REQUIRED IN ORDER TO
LIMIT CRYSTAL DRIVE LEVELS. THIS IS PARTICULARLY
IMPORTANT FOR LOW FREQUENCY CRYSTALS (SEE TEXT).
