P87LPC764 NXP Semiconductors, P87LPC764 Datasheet - Page 53

• Manufacturer Part Number: P87LPC764
• Description: The P87LPC764 is a 20-pin single-chip microcontroller designed forlow pin count applications demanding high-integration, low costsolutions over a wide range of performance requirements
• Manufacturer: NXP Semiconductors

1. Parameters are valid over operating temperature range unless otherwise specified.
2. Load capacitance for all outputs = 80 pF.
3. Parts are guaranteed to operate down to 0 Hz.
4. Applies only to an external clock source, not when a crystal is connected to the X1 and X2 pins.
5. For availability of other devices with this specification, please contact Philips sales office.
