? 2005 microchip technology inc. ds51292l-page 1 mplab ? icd 2 header specification introduction this document contains information about mplab ? icd 2 headers, which provide in-circuit debugging capabilities for specific microchip devices. a special icd/ice device is connected to a header board to be used with mplab icd 2. this device is mounted on the top of a header and its signals are routed to the mplab icd 2 connector (figure 1). on the bottom of the header is a socket that is used to connect to the target board. figure 1: mplab ? icd 2 module connection with pdip header special icd/ice versions of selected devices are needed to provide one or more of the following: ? the built-in debug circuitry that a device may lack ? additional pins for the clock, data and mclr functions required for icd ? dedicated program/data memory for icd icd versions are labeled with an icd suffix ( device -icd). for some devices, ice versions are available ( device -ice) and may be used with mplab icd 2 as icd devices. mplab ? icd 2 power in target application target socket mplab icd 2 header stand-off connector ** -icd device* jumpers *number of pins is determined by -icd device used. **number of stand-off pins is determined by mplab icd 2 header used. j2 j1 p1 module
mplab ? icd 2 ds51292l-page 2 ? 2005 microchip technology inc. headers for icd devices some devices have no built-in debug circuitry. therefore, special icd versions of these devices are required for mplab icd 2 operation. other devices have built-in debug circuitry and do not require a header to use mplab icd 2. however, some pins and memory must be used to support the icd function. therefore, for some of these devices, special icd versions offering additional pins (and sometimes memory) are available to provide more transparent debugging capabilities. currently-available headers and their associated icd devices/supported devices are shown in table 1. table 1: header types ? icd devices header part number icd device used devices supported v dd max 8 pin AC162050 pic12f675-icd (1) pic12f629/675 5.5 ac162058 pic12f683-icd pic12f683 5.5 14 pin ac162052 pic16f676-icd (1) pic16f630/676 5.5 ac162057 pic16f636-icd pic12f635, pic16f636 5.5 ac162055 pic16f684-icd pic16f684 5.5 ac162056 pic16f688-icd pic16f688 5.5 ac162059 pic16f505-icd pic10f200/2/4/6 pic12f508/509 pic16f505 5.5 ac162070 pic16f506-icd pic10f220/2 pic12f510 pic16f506 5.5 18 pin ac162053 pic16f648a-icd (1) pic16f627a/628a/648a 5.5 ac162054 pic16f716-icd pic16f716 5.5 20 pin ac162066 pic16f636-icd pic16f639 (dual die) 5.5 ac162060 pic16f785-icd pic16f785/hv785 5.5 ac162061 pic16f690-icd pic16f631/677 pic16f685/687/689/690 5.5 note 1: these devices cannot be programmed or read using mplab ? icd 2 while gp1/ra1 is high (v ih ). move circuitry that makes gp1/ra1 high to another i/o pin during development. see device programming specifications for more information.
header specification ? 2005 microchip technology inc. ds51292l-page 3 headers for ice devices devices that have built-in debug circuitry do not require a header to use mplab icd 2. however, some pins and memory must be used to support the icd function. special ice versions offering additional pins, memory and emulator functions can be used to provide superior debugging capabilities. currently-available headers and their associated ice devices/supported devices are shown in table 2. installation the mplab icd 2 header is installed by following these steps: 1. set up the header board. 2. connect the header and mplab icd 2. 3. connect the header and the target board. set up the header board to set up a header board: 1. if the icd device is not soldered onto the header, plug the icd device into the socket on the top of the header. 2. set any jumpers or switches to determine device functionality/selection as specified in the following sections. 8/14-pin headers for some headers, device peripherals need to be selected by setting jumper j1 to the appropriate position. this will have the effect of selecting the device. table 2: header types ? ice devices header part number ice device used devices supported v dd max 64/80 pin ac162062 pic18f87j10-ice pic18f65j10/85j10 pic18f65j15/85j15 pic18f66j10/86j10 pic18f66j15/86j15 pic18f67j10/87j10 3.6 device jumper setting peripheral function pic12f629 2-3 a/d disabled pic12f675 1-2 a/d enabled pic16f630 2-3 a/d disabled pic16f676 1-2 a/d enabled pic12f635 2-3 portc, comparator 2 disabled pic16f636 1-2 portc, comparator 2 enabled

mplab ? icd 2 ds51292l-page 6 ? 2005 microchip technology inc. programming no n-icd devices the mplab icd 2 header can only program the -icd device, not the regular device. to program non-icd devices with the mplab icd 2, use the universal programming module (ac162049) or design a modular interface connector on the target. see the appropriate specification for connections. for the most up-to-date device programming specifications, see the microchip website (www.microchip.com). calibration bits the calibration bits for the band gap and internal oscillator are always preserved by the mplab icd 2 to their factory settings. mplab icd 2 performance the picmicro ? mcu devices do not support partial program memory erase; therefore, users may experience slower mplab icd 2 performance than with other devices. additional information please refer to the mplab ? icd 2 in-circuit debugger user?s guide (ds51331), mplab ide help and the mplab icd 2 readme for additional information. schematics the following schematics show header electrical connections.
