STM32L422KBT6 IC MCU 32BIT 128KB FLASH 32LQFP

Apejuwe

Awọn ẹrọ STM32L422xx jẹ awọn oluṣakoso microcontrollers ultra-low-power da lori iṣẹ giga Arm® Cortex®-M4 32-bit RISC mojuto ti n ṣiṣẹ ni igbohunsafẹfẹ ti o to 80 MHz.Kotesi-M4 mojuto ṣe ẹya kan pato aaye Lilefoofo (FPU) eyiti o ṣe atilẹyin fun gbogbo Arm® awọn ilana ṣiṣe data-konge kanṣoṣo ati awọn iru data.O tun ṣe eto kikun ti awọn ilana DSP ati ẹyọ aabo iranti (MPU) eyiti o mu aabo ohun elo pọ si.Awọn ẹrọ STM32L422xx ṣe ifibọ awọn iranti iyara giga (Iranti filasi to 128 Kbyte, 40 Kbyte ti SRAM), wiwo awọn iranti iranti Quad SPI kan (wa lori gbogbo awọn idii) ati ibiti o ti ni ilọsiwaju ti I/Os ati awọn agbeegbe ti o sopọ si awọn ọkọ akero APB meji , meji AHB akero ati ki o kan 32-bit olona-AHB akero matrix.Awọn ẹrọ STM32L422xx ṣe ifibọ ọpọlọpọ awọn ọna aabo fun iranti Flash ifibọ ati SRAM: Idaabobo kika, kikọ aabo, aabo koodu kika ohun-ini ati ogiriina.Awọn ẹrọ naa nfunni ni iyara meji 12-bit ADC (5 Msps), awọn afiwera meji, ampilifaya iṣiṣẹ kan, RTC agbara kekere kan, aago 32-bit gbogbogbo-idi kan, aago 16-bit PWM igbẹhin si iṣakoso mọto, mẹrin gbogbogbo- idi 16-bit aago, ati meji 16-bit kekere-agbara aago.
