TC1767
Introduction
Features
• Fast synchronous serial interface to connect power switches in particular, or other
peripheral devices via serial buses
• High-speed synchronous serial transmission on downstream channel
– Serial output clock frequency: fFCL = fMSC/2
– Fractional clock divider for precise frequency control of serial clock fMSC
– Command, data, and passive frame types
– Start of serial frame: Software-controlled, timer-controlled, or free-running
– Programmable upstream data frame length (16 or 12 bits)
– Transmission with or without SEL bit
– Flexible chip select generation indicates status during serial frame transmission
– Emergency stop without CPU intervention
• Low-speed asynchronous serial reception on upstream channel
– Baud rate: fMSC divided by 4, 8, 16, 32, 64, 128, or 256
– Standard asynchronous serial frames
– Parity error checker
– 8-to-1 input multiplexer for SDI lines
– Built-in spike filter on SDI lines
• Selectable pin types of downstream channel interface:
four LVDS differential output drivers or four digital GPIO pins
