evaluates: max11312 max11312pmb# peripheral module general description the max11312pmb# peripheral module (pmod?) provides the necessary hardware to interface the max11312 12-channel programmable mixed-signal i/o device to any system that utilizes pmod-compatible expansion ports configurable for i 2 c communication. the device is a 12-bit multichannel analog-to-digital converter (adc) and a 12-bit buffered dac output in a single ic. this device also includes software-configurable general-purpose i/o ports. a local and two remote temperature sensors keep track of junction and environmental temperatures. adjacent pairs of ports can also be used as logic translator or analog switch. each pin can also be used as a positive input of a comparator with programmable threshold. refer to the max11312 ic data sheet for detailed information regarding operation of the device and the usb2pmb2 (munich) adapter board data sheet for detailed information regarding the munich board and gui. refer to the max11312 peripheral module and munich adaptor board quick start guide for step-by-step evaluation instructions. refer to the max11312 configuration software user guide for detailed information using the design tool. features up to 12 12-bit adc programmable inputs up to 12 12-bit dacs with 25ma current capability ? 70ma max at +12v with on-board power supply ? 30ma (typ) at -12v with on-board power supply ? use external power supply at vddio (vddio jumper removed) if more current is needed up to 12 digital i/os up to 12 comparator inputs internal or external reference for adc and dac individually selectable adc references for each port internal temperature sensor (-40c to +125c, 3c accuracy) two remote temperature-measurement controllers (-40c to +150c, 3c accuracy) 2 x 6-pin pmod-compatible connector ( i 2 c ) rohs compliant proven pcb layout fully assembled and tested 19-7769; rev 0; 2/16 ordering information appears at end of data sheet. pmod is a trademark of digilent inc. peripheral module board photo downloaded from: http:///
maxim integrated 2 www.maximintegrated.com evaluates: max11312 max11312pmb# peripheral module detailed description i 2 c interface the max11312pmb# pmod can plug directly into a pmod-compatible port (configured for i 2 c) through the x1 connector. for information on the i 2 c protocol, refer to the max11312 ic data sheet. connector x1 provides connection of the module to the pmod host. see table 1 and figure 1 for detailed description. connector jp1 provides selection of +3.3v either from the pmod_supply or an external supply (x2). connectors sv1 and sv2 provide connection to the ic pins (max11312 ports 0C11). connector sv3 is ground. connectors ext_temp1 and ext_temp2 provide connection to the external temperature sensors. connector vddio provides connection to the avddio pins of the device, which is connected to the +12v power supply connector vssio provides connection to the avssio pins of the device, which is the analog negative supply for mixed-signal ports. install the vssio jumper from 1 to 2 to connect avssio to ground. install vssio from 2 to 3 to connect avssio to -12v. figure 1. x1: pmod i 2 c connector pin configuration table 1. connector x1 (i 2 c communication) 7 10 8 9 11 12 1 4 2 3 5 6 x1 i 2 c ad0 ad1 scl sda gnd 3.3v 3.3v . gnd cnvtb intb pin signal description 1 ad0 max11312 slave address bit 0 2 ad1 max11312 slave address bit 1 3 scl max11312 serial interface clock input 4 sda max11312 serial interface input and output 5, 11 gnd ground 6, 12 +3.3v +3.3v power supplies 7 intb interrupt open-drain output. asserted low when the max11312 issues an interrupt. 8 no connection 9 no connection 10 cnvtb adc conversion control input. assert low to initiate an adc conversion. downloaded from: http:///
maxim integrated 3 www.maximintegrated.com evaluates: max11312 max11312pmb# peripheral module default jumper setting verify that all jumpers are in their default positions, as follows: 1) jumper vddio: connect from vddio to +12v. 2) jumper vssio: connect from vssio to gnd. 3) jumpers ext_temp1 and ext_temp2: open. 4) jumper jp1: connect pmod_supply to +3.3v, jp1-1 to jp1-2. power supplies the pmod contains the max8752 step-up dc-dc converter (u3), which upconverts the +3.3v power supply from the pmod x1 connector to +13v. the max5084 (u2) linear regulator then regulates the +13v input to +5v output voltage, providing power supply to the positive analog supply avdd of the ic. another max5084 (u1) provides a +12v power supply to the positive analog supply of the mixed-signal ports (avddio) of the ic. in addition, the max629 (u5) provides -12v power supply to the vssio from +3.3v input. for bipolar applications, use an external power supply to provide negative voltage for avssio. see figure 2 . software graphical user interface (gui) the munich software gui is provided to facilitate evaluation of the pmod. visit www.maximintegrated.com/evkitsoftware to download the latest version of the munich gui software. refer to the max11312pmb# peripheral module and munich (usb2pmb2) adapter board quick start guide for step-by-step evaluation using the munich gui. external power supply the on-board power supply provides 70ma max current at vddio = +12v. if additional current is needed, use an external power supply by removing the jumper connecting vddio to +12v and connecting a +12v external power supply to the vddio pin. for bipolar applications, remove the jumper from vssio pin to gnd and connect it from pin 2 to pin 3. see figure 2 and refer to the max11312 ic data sheet for details. external temperature sensors two-pin connector vertical headers, ext_temp1 and ext_temp2, are provided to measure the environment temperature. connect the base and collector of diode- connected transistors, such as the 2n3906 to the temp1 or temp2 pin and the emitter to the ext pin to measure the external temperature. see figures 3 and 4 . figure 2. power-supply block diagram +3 .3v (from usb2pmb2 board x1 co nn ector ) +3.3v(from external pow ery s upp ly ) jp1 +3.3v (dvdd) ma x8752 ( u3) +13v ma x5084 ( u2) +5v (avdd ) ma x5084( u1) +12v (vddio) max629 (u5) -12v (vss io ) max11312pmb vssio ( gn d or - 12 v) downloaded from: http:///
