♠ Multiprotocol wireless 32-bit MCU Arm®-based Cortex®-M4 ene-FPU, Bluetooth® 5.2 kanye nesixazululo somsakazo esingu-802.15.4
I-STM32WB55xx kanye ne-STM32WB35xx multiprotocol amadivayisi angenantambo nanamandla aphansi ashumeka umsakazo onamandla futhi onamandla aphansi kakhulu othobelana nokucaciswa kwe-Bluetooth® Low Energy SIG 5.2 kanye ne-IEEE 802.15.4-2011. Ziqukethe i-Arm® Cortex®-M0+ ezinikele yokwenza wonke umsebenzi wesikhathi sangempela ophansi wesendlalelo.
Amadivayisi aklanyelwe ukuba abe namandla aphansi kakhulu futhi asekelwe kumongo osebenza kakhulu we-Arm® Cortex®-M4 32-bit RISC osebenza imvamisa yokufika ku-64 MHz. Lo mnyombo ufaka iyunithi yephoyinti elintantayo (i-FPU) ukunemba okukodwa okusekela yonke imiyalelo ye-Arm® yokunemba okukodwa yokucubungula idatha nezinhlobo zedatha. Iphinde isebenzise isethi egcwele yemiyalelo ye-DSP kanye neyunithi yokuvikela inkumbulo (MPU) ethuthukisa ukuphepha kohlelo lokusebenza.
Ukuxhumana okuthuthukisiwe okuphakathi kwamaprosesa kunikezwa yi-IPCC ngamashaneli ayisithupha aqondiswa kabili. I-HSEM inikeza ama-semaphores e-hardware asetshenziselwa ukwabelana ngezinsiza ezivamile phakathi kwamaphrosesa amabili.
Amadivayisi ashumeka izinkumbulo zesivinini esikhulu (kufika ku-1 Mbyte yememori ye-Flash ye-STM32WB55xx, kufika ku-512 Kbytes we-STM32WB35xx, kufika ku-256 Kbytes we-SRAM ye-STM32WB55xx, 96 Kbytes ye-STM32WB55xxxxxxxxxxxxxbpcnbsp; uhla olubanzi lwama-I/O nama-peripherals athuthukisiwe.
Ukudluliswa kwedatha okuqondile phakathi kwenkumbulo nama-peripherals kanye nokusuka enkumbulweni kuye enkumbulweni kusekelwa iziteshi eziyishumi nane ze-DMA ezinomdwebo ogcwele wesiteshi oguquguqukayo nge-peripheral ye-DMAMUX.
Amadivayisi afaka izindlela ezimbalwa zememori ye-Flash eshumekiwe kanye ne-SRAM: ukuvikela ukufunda, ukuvikeleka kokubhala kanye nokuvikelwa kokufunda ikhodi yobunikazi. Izingxenye zememori zingavikelwa ukufinyelela okukhethekile kwe-Cortex® -M0+.
Izinjini ezimbili zokubethela ze-AES, i-PKA ne-RNG zinika amandla ungqimba oluphansi lwe-MAC kanye ne-cryptography yesendlalelo esiphezulu. Isici sesitoreji sokhiye wekhasimende singasetshenziswa ukugcina okhiye befihliwe. Amadivayisi anikezela nge-ADC esheshayo engu-12-bit kanye neziqhathanisi ezimbili zamandla aphansi kakhulu ahlobene nejeneretha yamandla kagesi eyireferensi yokunemba okuphezulu.
Lawa madivayisi ashumeka i-RTC enamandla aphansi, isibali sikhathi esisodwa esithuthukisiwe esingu-16-bit, isibali sikhathi senhloso ejwayelekile esingu-32-bit, izibali sikhathi ezimbili zenhloso evamile engu-16-bit, kanye nezibali-sikhathi zamandla aphansi angu-16-bit. Ngaphezu kwalokho, kufika ku-18 iziteshi ze-capacitive sensing ziyatholakala ze-STM32WB55xx (hhayi kuphakheji ye-UFQFPN48).
I-STM32WB55xx iphinde ishumeke umshayeli we-LCD ohlanganisiwe ofika ku-8x40 noma 4x44, ngesiguquli sangaphakathi sokukhuphuka. I-STM32WB55xx ne-STM32WB35xx iphinde ibe nezindawo zokuxhumana ezisezingeni nezithuthukile, okuyi-USART eyodwa (ISO 7816, IrDA, Modbus nemodi ye-Smartcard), i-UART (LPUART) eyodwa enamandla aphansi (LPUART), ama-I2C amabili (SMBus/PMBus), ama-SPI amabili (eyodwa ye-STM32WHz) okulalelwayo okuya phezulu kwe-35x35x35 eneziteshi ezimbili nama-PDM amathathu, idivayisi eyodwa ye-USB 2.0 FS ene-oscillator eshumekiwe engena-crystal, esekela i-BCD ne-LPM kanye ne-Quad-SPI eyodwa enekhono le-execute-in-place (XIP).
I-STM32WB55xx ne-STM32WB35xx isebenza ku--40 kuya ku-+105 °C (+125 °C junction) kanye -40 kuya ku-+85 °C (+105 °C junction) ibanga lokushisa lisuka ku-1.71 kuya ku-3.6 V. Isethi ebanzi yamamodi okonga amandla inika amandla ukuklanywa kwezinhlelo zokusebenza zamandla amancane.
Amadivayisi ahlanganisa amandla azimele wokufaka kwe-analog ye-ADC.
