6 / 46 page CS5467 6 DS714F3 2. PIN DESCRIPTION Clock Generator Crystal Out Crystal In 1,28 XOUT, XIN — Connect to an external quartz crystal. Alternatively, an external clock can be sup- plied to the XIN pin to provide the system clock for the device. CPU Clock Output 2 CPUCLK — Logic-level output from crystal oscillator. Can be used to clock an external CPU. Control Pins and Serial Data I/O Serial Clock 5 SCLK — Clocks serial data from the SDI pin and to the SDO pin when CS is low. SCLK is a Schmitt-trigger input when MODE is low and a driven output when MODE is high. Serial Data Output 6 SDO — Serial data output. Data is clocked out by SCLK. Chip Select 7 CS — An input that enables the serial interface when MODE is low and a driven output when MODE is high. Mode Select 8 MODE — High selects external E2PROM, Low selects external microcontroller. MODE includes a weak internal pull-down and therefore selects microcontroller mode if not connected. Energy Output 22, 25, 26 E3, E1, E2 — Primarily active-low energy pulse outputs. These can be programmed to output other conditions. Reset 23 RESET — An active-low Schmitt-trigger input used to reset the chip. Interrupt 24 INT — Active-low output, indicates that an enabled condition has occurred. Serial Data Input 27 SDI — Serial data input. Data is clocked in by SCLK. Analog Inputs/Outputs Differential Voltage Inputs 9,10 13, 14 VIN1+, VIN1-, VIN2+, VIN2- — Differential analog inputs for the voltage channels. Differential Current Inputs 20,19, 16,15 IIN1+, IIN1-, IIN2+, IIN2- — Differential analog inputs for the current channels. Voltage Reference Output 11 VREFOUT — The on-chip voltage reference output. Nominally 2.5 V, referenced to AGND. Voltage Reference Input 12 VREFIN — The voltage reference input. Can be connected to VREFOUT or external 2.5 V refer- ence. Power Supply Connections Positive Digital Supply 3 VD+ — The positive digital supply. Digital Ground 4 DGND — Digital ground. Positive Analog Supply 18 VA+ — The positive analog supply. Analog Ground 17 AGND — Analog ground. Power Fail Monitor 21 PFMON — Used to monitor the unregulated power supply via a resistive divider. If the PFMON voltage drops below its low limit, the low-supply detect (LSD) bit is set in the Status register.
