pic18f66k80 plug-in module for picdem? pic18 explorer board overview the pic18f66k80 plug-in module (pim) is an accessory to the picdem? pic18 explorer board that allows users to easily experiment with the pic18f66k80 family of microcontrollers. pic18f66k80 is the superset member of the family and this pim can be used to evaluate and develop with the pic18f66k80 products. the pim takes the place of the on-board pic18f8722 device. this enables users to quickly evaluate the new pic18fk flash devices without having to buy a completely new demo board. getting started with the pim 1. make sure the on-board pic18f66k80 is programmed to allow the mclr reset pin to function as a reset pin. if the mclr is configured to be used for general purpose i/o, the on-board pic18f66k80 may interfere with pim usage, even when the board is switched to ice mode. 2. verify that the picdem pic18 explorer board is not powered. 3. set switch, s4, to the ?ice? position. this will hold the on-board pic18f8722 in reset, allowing the pim to function instead. 4. line up the pim so its 3-pin female header aligns with the 3-pin riser on the picdem pic18 explorer board, then plug the pim into the demo board. 5. apply power to the demo board. be sure that v dd is correct for the device being used (5v for pic18f66k80). if it is not correct, disconnect power and check that the 3-pin female header is aligned properly with the demo board?s 3-pin riser. changes to picdem pic18 explorer board configuration the difference of available i/o pins between the picdem pic18 explorer board?s pic18f8722 device and the pim?s pic18f66k80 device causes some changes in the operation of the picdem pic18 explorer board. 1. most i/o lines connected to the picdem pic18 explorer board?s pictail? connector, j3/j5/j7/j11 silkscreen, will map 1:1 with pic18f66k80 i/o pins. 2. the uart pinout is different on the pic18f66k80 compared to other pic18 devices. in order to use serial communication through the serial port on the pic18 explorer board, pin, rg0, must be connected to rc7 and pin, rg1, must be con- nected to rc6. this can be done with two jumpers connecting the two pins using the two debug headers on the explorer board. 3. the pic18f66k80 can operate between 1.8v and 5v. the supplied voltage can be adjusted by populating the pim board?s r101 and r102 resistors. for more detailed information on varying the device voltage, see ?picdem? pic18 explorer demonstration board user?s guide? , section 2.3.3 ? calculating other v dd values ? . demonstration firmware the pim is programmed with firmware demonstrating basic features on the pic18 explorer board. the source for the pic18f66k80 pim demo code may be downloaded from the microchip web site. for more information the complete schematic and user?s guide for the picdem pic18 explorer board, as well as the data sheet for the pic18f66k80 family of microcontrollers are available on the microchip web site: http://www.microchip.com/pic18k europe austria - weis - 43-7242-2244-39 denmark - copenhagen - 45-4450-2828 france - paris - 33-1-69-53-63-20 germany - munich - 49-89-627-144-0 italy - milan - 39-0331-742611 netherlands - drunen - 31-416-690399 spain - madrid - 34-91-708-08-90 uk - wokingham - 44-118-921-5869 08/04/10 americas atlanta - 678-957-9614 boston - 774-760-0087 chicago - 630-285-0071 cleveland - 216-447-0464 dallas - 972-818-7423 detroit - 248-538-2250 kokomo - 765-864-8360 los angeles - 949-462-9523 phoenix - 480-792-7200 santa clara - 408-961-6444 toronto - 905-673-0699 asia/pacific australia - sydney - 61-2-9868-6733 china - beijing - 86-10-8528-2100 china - chengdu - 86-28-8665-5511 china - chongqing - 86-23-8980-9588 china - hong kong sar - 852-2401-1200 china - nanjing- 86-25-8473-2460 china - qingdao - 86-532-8502-7355 china - shanghai - 86-21-5407-5533 china - shenyang - 86-24-2334-2829 china - shenzhen - 86-755-8203-2660 china - wuhan - 86-27-5980-5300 china - xiamen - 86-592-2388138 china - xian - 86-29-8833-7252 china - zhuhai - 86-756-3210040 india - bangalore - 91-80-3090-4444 india - new delhi - 91-11-4160-8631 india - pune - 91-20-2566-1512 japan - yokohama - 81-45-471-6166 korea - daegu - 82-53-744-4301 korea - seoul - 82-2-554-7200 malaysia - kuala lumpur - 60-3-6201-9857 malaysia - penang - 60-4-227-8870 philippines - manila - 63-2-634-9065 singapore - 65-6334-8870 taiwan - hsin chu - 886-3-6578-300 taiwan - kaohsiung - 886-7-213-7830 taiwan - taipei - 886-2-2500-6610 thailand - bangkok - 66-2-694-1351 microchip technology inc. ?
