Data Sheet
PowerPC 440SP Embedded Processor
Features include:
• Two IIC interfaces provided
‚
2
• Support for Philips Semiconductors I C Specification, dated 1995
• Operation at 100kHz or 400kHz
• 8-bit data
• 10- or 7-bit address
• Slave transmitter and receiver
• Master transmitter and receiver
• Multiple bus masters
• Supports fixed V IIC interface
DD
• Two independent 4 x 1 byte data buffers
• Twelve memory-mapped, fully programmable configuration registers
• One programmable interrupt request signal
• Full management of all IIC bus protocols
• Programmable error recovery
• Port 0 supports serial Bootstrap ROM with default parameters override at initialization
General Purpose Timers (GPT)
Provides a time base counter and system timers additional to those defined in the processor core.
• 32-bit time base counter driven by the OPB bus clock
• Seven 32-bit compare timers
General Purpose IO (GPIO) Controller
• Controller functions and GPIO registers are programmed and accessed by means of memory-mapped OPB
bus master accesses.
• The 32 GPIOs are pin-shared with other functions. DCRs control whether a particular pin that has GPIO
capabilities acts as a GPIO or is used for another purpose.
• Each GPIO output is a separately programmable tri-state driver (pull-up, pull-down, or open-drain).
