Functional Description
Multicore Propeller Microcontroller System
•
64 KB I2C EEPROM for non-volatile program and data storage.
•
32-bit, 8-core Propeller P8X32A microcontroller
•
3.3 V, 500 mA voltage regulator
•
5.00 MHz crystal oscillator
The Propeller P8X32A uses I/O pins P28 and P29 to communicate with the 64 KB I2C EEPROM for
program and data storage. The lower 32 KB contains the program that the Propeller loads on reset. The
upper 32 KB can be used for non-volatile data storage. The crystal oscillator connected to the Propeller
provides a clock signal for the system. The Propeller can multiply its 5 MHz oscillator signal by up to 16
for a system clock frequency of 80 MHz.
See the Propeller I/O Pin Assignments on page 9 for additional details.
