The MX877 interfaces to a microprocessor through a standard 3 wire serial interface and an active low chip select, or can be used in a parallel-in, parallel-out configuration. Parallel data is transferred to the I/O register of the MX877 through the parallel input pins, IN0 through IN7 on the falling edge of the chip select pin, CS . When CS is in a logic low state, serial data can be transferred to the I/O register through the serial input pin, SDI, and from the I/O register through the serial output pin, SDO. Parallel or serial input data is transferred from the I/O register to the latch and high voltage output drivers, OUT0 through OUT7, on the positive edge of CS . This data remains latched until the next positive edge of CS . The 8-bit I/O shift register is clocked by the serial clock pin, SCK. Serial data presented at the SDI pin is transferred to the shift register on the positive edge of SCK. Data shifts out of the register through the SDO pin on the negative edge of SCK. SDI and SCK are ignored, and SDO transitions to a high impedance condition when CS is at a logic high state. Serial data is received by the MX877 through the SDI pin. This data is accepted on the rising edge of SCK. A specific output is programmed to a logic high state if SDI is at a logic high state during the rising edge of SCK. Conversely, a specific output is programmed to a logic low state if SDI is at a logic low state during the rising edge of SCK. Outputs transition to their programmed states on the positive edge of CS if the output enable pin, OE is in a logic high state. The MSB input data (IN7) is presented at the serial output pin, SDO on the falling edge of CS . Input data from IN6 through IN0 is sequentially presented at SDO on negative SCK transitions if CS remains in a logic low state. If CS is at a logic low state beyond 8 cycles of SCK, SDI data that has propagated through the I/O register will then be presented at SDO. The SDO pin transitions to a high impedance state when CS is in a logic level high state, thus allowing multiple serial peripherals to share the microprocessor data pin. IXYS Serial Data Transfer Example IN7 IN6 IN5 IN4 IN3 IN2 IN1 IN0 SDI CS* SCK SDO 0 0 1 0 1 1 1 0 0 0 1 0 1 1 1 0 1 t1 0 0 0 0 1 1 0 SDI at time t1 1 0 0 0 0 1 1 0 OUT7 OUT6 OUT5 OUT4 OUT3 OUT2 OUT1 OUT0 Devices may be serially cascaded by connecting SDO to SDI of the next device. Pins SCK and CS are common to all devices in serial cascade. For n-cascaded devices the CS should remain low for 8n cycles of SCK. An output enable pin, OE enables the driver outputs OUT0 through OUT7 when logic high. A logic low level on OE forces the OUT0 through OUT7 outputs to a high impedance state. The MX877 can also operate as a parallel-in, parallel-out level shifter and driver. SCK must remain at a logic low state when operating in this mode. Parallel input data presented to IN0 through IN7 is captured on the falling edge of CS . This data is transferred to OUT0 through OUT7 on the rising edge of CS , and remains latched until the next rising edge of CS .
