X5114  
System Controller  
FEATURES  
DESCRIPTION  
• Simplifies Backplane Communications  
• Monitor Fault and “Hot Docking” Conditions  
• Ten Level Selectable Input Threshold  
• Two Fully Redundant SPI Serial I/O Ports  
• Programmable Output or Input Port Pins  
—16 General I/O pins  
The X5114 is a single-chip system controller that is used  
in applications such as multiprocessing, telecommunica-  
tions, data communications, cable systems, set top  
boxes, etc. The chip can implement features such as  
backplane communication, hot docking, cable diagnos-  
tics, etc.  
—8 bit Port with 4 Handshake Modes  
• Single Read Input Mode  
The X5114 makes extensive use of nonvolatile memory  
with 4,096 bits of general purpose EEPROM, nonvolatile  
configuration registers, and nonvolatile programming of  
the port pins. The ports can be set up as sixteen general  
I/Os with pin selectable data direction (including eight  
inputs with nonvolatile threshold selections) or as an  
eight bit port with handshake. The chip is controlled via  
two redundant 2MHz SPI serial ports.  
• Multiple Read Input Mode  
• Output Mode  
• Bidirectional Mode  
Port Tristate Control  
• Programmable Interrupt and Mask Options  
• 8-bit Direct Address Decoder allows Cascaded  
255+ devices on one SPI bus  
• 4K bits of EEPROM with 32 byte page write  
• Default Output Data on Port at Power-up  
• High Reliability EEPROM  
A sophisticated interrupt controller provides notification of  
a failed SPI command, changing conditions on an input,  
handshake status, and I/O errors. Interrupts are  
maskable.  
—Endurance - 105 Data Changes  
—Data Retention - 100 years  
On-chip EEPROM provides nonvolatile storage of  
system status, manufacturing information, board ID or  
other parameters.  
• 44-Pin PLCC, 48-Lead TQFP
