ATSAMD21E18A-MU IC MCU 32BIT 256KB FLASH 32QFN

Kev piav qhia

SAM D21 / DA1 yog cov khoom siv hluav taws xob qis qis siv 32-ntsis Arm® Cortex®-M0+ processor, thiab xws li 32-pins rau 64-pins nrog txog 256 KB Flash thiab 32 KB ntawm SRAM.SAM D21 / DA1 ua haujlwm ntawm qhov siab tshaj plaws ntawm 48 MHz thiab ncav cuag 2.46 CoreMark / MHz.Lawv yog tsim los rau yooj yim thiab intuitive tsiv teb tsaws nrog zoo tib yam peripheral modules, hex tshaj code, zoo tib yam linear chaw nyob daim ntawv qhia, thiab tus pin tau tshaj migration paths ntawm tag nrho cov pab kiag li lawm nyob rau hauv cov khoom series.Tag nrho cov khoom siv suav nrog cov khoom siv ntse thiab hloov tau yooj yim, Cov Txheej Txheem Txheej Txheem rau cov teeb liab sib cuam tshuam, thiab kev txhawb nqa rau lub khawm kov capacitive, slider, thiab log neeg siv interfaces.SAM D21 / DA1 muab cov yam ntxwv hauv qab no: Hauv-system programmable Flash, 12-channel Direct Memory Access Controller (DMAC), 12-channel Event System, programmable Interrupt Controller, mus txog 52 programmable I / O pins, 32-ntsis tiag -Lub Sijhawm Teev Sijhawm thiab Daim Ntawv Teev Sijhawm (RTC), txog li tsib 16-ntsis Timer / Counters (TC) thiab mus txog plaub 24-ntsis Timer / Counters for Control (TCC), qhov twg txhua TC tuaj yeem teeb tsa los ua cov zaus thiab waveform tiam, raug qhov kev pab cuam lub sij hawm los yog input capture nrog lub sij hawm thiab zaus ntsuas ntawm cov teeb liab.Cov TCs tuaj yeem ua haujlwm hauv 8-ntsis lossis 16-ntsis hom, xaiv TCs tuaj yeem ua haujlwm los ua 32-ntsis TC, thiab peb lub sijhawm / lub txee tau txuas ntxiv ua haujlwm tau zoo rau lub cev muaj zog, teeb pom kev zoo, thiab lwm yam kev siv tswj.Cov koob muab ib qho puv ceev USB 2.0 embedded host thiab ntaus ntawv interface;mus txog rau rau Serial Communication Modules (SERCOM) uas txhua tus tuaj yeem teeb tsa los ua USART, UART, SPI, I2C mus txog 3.4 MHz, SMBus, PMBus, thiab LIN tus neeg siv khoom;ob-channel I 2S interface;mus txog nees nkaum-channel 350 ksps 12-ntsis ADC nrog cov programmable nce thiab xaiv tau oversampling thiab decimation txhawb nqa txog 16-ntsis daws teeb meem, ib qho 10-ntsis 350 ksps DAC, txog li plaub analog piv nrog qhov rai hom, Peripheral Touch Controller (PTG) txhawb nqa mus txog 256 nyees khawm, sliders, lub log, thiab qhov sib thooj ntawm qhov sib txawv;programmable Watchdog Timer (WDT), xim av-tawm ntes thiab fais fab rov pib dua thiab ob-pin Serial Wire Debug (SWD) program thiab debug interface.Txhua yam khoom siv muaj qhov tseeb thiab tsis muaj zog sab nraud thiab sab hauv oscillators.Txhua oscillators tuaj yeem siv los ua qhov chaw rau lub kaw lus moos.Lub moos sib txawv tuaj yeem tsim kho tus kheej kom khiav ntawm ntau zaus, ua kom lub zog txuag los ntawm kev khiav txhua qhov peripheral ntawm nws lub sijhawm zoo moos, thiab yog li tuav lub CPU siab zaus thaum txo hwj chim noj.
