Iyo TMS320LF240xA uye TMS320LC240xA zvishandiso, nhengo nyowani dzeTMS320C24x™;chizvarwa chedhijitari chiratidzo processor (DSP) controller, chikamu cheTMS320C2000™;chikuva che fixed-point DSPs.Iwo 240xA zvishandiso zvinopa yakakwidziridzwa TMS320™;DSP yekuvaka dhizaini yeC2xx musimboti CPU yemutengo wakaderera, yakaderera-simba, uye yakakwirira-kuita kugadzirisa kugona.Zvizhinji zvemberi zvemberi, zvakagadziridzwa zvedhijitari mota uye mafambiro ekudzora zvikumbiro, zvakabatanidzwa kuti zvipe yechokwadi imwe-chip DSP controller.Ipo kodhi-inoenderana neiyo iripo C24x™;DSP controller zvishandiso, iyo 240xA inopa yakawedzera mashandiro ekuita (40 MIPS) uye nhanho yepamusoro yekubatanidzwa kweperipheral.Ona TMS320x240xA Chidimbu Chidimbu chikamu chemidziyo-chaiyo maficha.
Chizvarwa che240xA chinopa nhevedzano yehukuru hwekurangarira uye akasiyana maperipheral akarongedzerwa kusangana nemutengo chaiwo / mapoinzi ekuita anodiwa neakasiyana maapplication.Flash madivayiri anosvika 32K mazwi anopa inodhura-inoshanda reprogrammable mhinduro yekugadzira vhoriyamu.Iyo 240xA zvishandiso zvinopa password-yakavakirwa "kodhi chengetedzo" ficha iyo inobatsira mukudzivirira kudzokororwa kusingatenderwe kwekodhi yemuridzi yakachengetwa mu-chip Flash/ROM.Ziva kuti Flash-based zvishandiso zvine 256-izwi bhutsu ROM yekufambisira mu-circuit programming.Mhuri ye240xA inosanganisirawo midziyo yeROM iyo yakazara pini-kupini inoenderana neFlash vamwe vavo.
Ese 240xA zvishandiso zvinopa inokwana imwe chiitiko maneja module iyo yakagadziridzwa yedhijitari mota kutonga uye simba rekushandura mashandisirwo.Kugona kweiyi module kunosanganisira pakati- uye / kana kumucheto-yakarongedzerwa PWM chizvarwa, programmable deadband kudzivirira kupfura-kuburikidza nekukanganisa, uye synchronized analog-to-digital kutendeuka.Midziyo ine mbiri mbiri mamaneja inogonesa akawanda mota uye/kana inoshandura kudzora ine imwechete 240xA DSP controller.Sarudza mapini eEV akapihwa "input-qualifier" sedunhu, izvo zvinoderedza kusaziva kwepini-kukonzeresa nema glitches.
Iyo yepamusoro-performance, 10-bit analog-to-digital converter (ADC) ine hushoma hwekushandura nguva ye375 ns uye inopa kusvika kugumi nematanhatu nzira dzeanalogi.Iyo autosequencing kugona kweADC inobvumira huwandu hwegumi nematanhatu shanduko kuti dziitike muchikamu chekushandura chimwe chete pasina chero CPU pamusoro.
Iyo serial yekutaurirana interface (SCI) inosanganiswa pane ese maturusi kupa asynchronous kutaurirana kune mamwe maturusi ari muhurongwa.Kune masisitimu anoda imwe nzira yekutaurirana, iyo 2407A, 2406A, 2404A, uye 2403A inopa 16-bit synchronous serial peripheral interface (SPI).Iyo 2407A, 2406A, uye 2403A inopa controller nharaunda network (CAN) yekutaurirana module inosangana ne2.0B zvakatemwa.Kuti uwedzere kuchinjika kwechishandiso, mapini anoshanda anogadzirika zvakare seyakajairwa-chinangwa chekupinza/zvinobuda (GPIOs).
Kugadzirisa nguva yekusimudzira, JTAG-inoenderana scan-based emulation yakasanganiswa mumidziyo yese.Izvi zvinopa zvisiri-inopindira-chaiyo-nguva kugona kunodiwa kugadzirisa madhijitari ekudzora masisitimu.Iyo yakazara sutu yekodhi-chizvarwa maturusi kubva kuC compilers kune indasitiri-yakajairwa Code Composer Studio™;debugger inotsigira mhuri iyi.Vazhinji vagadziri vebato rechitatu havangope maturusi-chikamu chekuvandudza maturusi, asiwo system-level dhizaini uye rutsigiro rwekusimudzira.
