Evaluates: MAX11300 MAX11300PMB1 Peripheral Module General Description Features and Benefits The MAX11300PMB1 peripheral module (Pmod) pro- Up to 20 12-Bit ADC Programmable Inputs vides the necessary hardware to interface the MAX11300 Up to 20 12-Bit DACs with 25mA Current Capability 20-channel programmable mixed-signal I/O device to any 70mA max at +12V with On-Board Power Supply system that utilizes Pmod-compatible expansion ports Use External Power Supply at VDDIO (VDDIO configurable for SPI communication. The device is a 12-bit Jumper Removed) if More Current is Needed multichannel analog-to-digital converter (ADC) and a Up to 20 Digital I/Os 12-bit buffered DAC output in a single IC. This device also Up to 20 Comparator Inputs includes software-configurable general-purpose I/O ports. A local and two remote temperature sensors keep track of Internal or External Reference for ADC and DAC junction and environmental temperatures. Adjacent pairs Individually Selectable ADC References for Each Port of ports can also be used as logic translator or analog Internal Temperature Sensor (-40C to +125C, 3C switch. Each pin can also be used as a positive input of a Accuracy) comparator with programmable threshold. Two Remote Temperature-Measurement Controllers Refer to the MAX11300 IC data sheet for detailed (-40C to +150C, 3C Accuracy) information regarding operation of the device and the USB2PMB1 (Munich) adapter board data sheet for 2x6-Pin Pmod-Compatible Connector (SPI) detailed information regarding the Munich board and GUI. RoHS Compliant Refer to the MAX11300 peripheral module and Munich Proven PCB Layout adaptor board Quick Start Guide for step-by-step evalu- ation instructions. Refer to the MAX11300 Configuration Fully Assembled and Tested Software User Guide for detailed information using the design tool. Ordering Information appears at end of data sheet. Peripheral Module Board Photo Pmod is a trademark of Digilent Inc. 19-6914 Rev 2 6/14Evaluates: MAX11300 MAX11300PMB1 Peripheral Module Detailed Description SPI Interface X1 The MAX11300PMB1 Pmod can plug directly into a Pmod-compatible port (configured for SPI) through the INTB X1 connector. For information on the SPI protocol, refer 7 1 CS to the MAX11300 IC data sheet. Connector X1 provides connection of the module to 8 2 MOSI the Pmod host. See Table 1 and Figure 1 for detailed description. MISO 9 3 Connectors SV1 and SV2 provide connection to the IC pins (MAX11300 ports 019). Connector SV3 is CNVTB 10 4 SCLK ground. Connectors EXT TEMP1 and EXT TEMP2 provide GND 11 5 GND connection to the external temperature sensors. Connector VDDIO provides connection to the 3.3V 3.3V . 12 6 AVDDIO pins of the device, which is connected to the +12V power supply Connector VSSIO provides connection to the SPI AVSSIO pins of the device, which is the analog negative supply for mixed-signal ports. Install the VSSIO jumper to connect AVSSIO to ground. Figure 1. X1: Pmod SPI Connector Pin Configuration Table 1. Connector X1 (SPI Communication) PIN SIGNAL DESCRIPTION 1 CS Chip Select.
