5. Microprocessor Interfaces
The LTC1091/LTC1092/LTC1093/LTC1094 can interface
directly (without external hardware) to most popular
microprocessor (MPU) synchronous serial formats (see
Table 1). If an MPU without a dedicated serial port is used,
then three or four of the MPU’s parallel port lines can be
programmed to form the serial link to the LTC1091/
LTC1092/LTC1093/LTC1094. Included here are one serial
interface example and one example showing a parallel port
programmed to form the serial interface.
