♠ Mphamvu zotsika kwambiri za Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, mpaka 512KB Flash, 160KB SRAM, analogi, mawu
Zipangizo za STM32L451xx ndi ma ultra-low-power microcontrollers kutengera Arm® Cortex®-M4 32-bit RISC core yogwira ntchito kwambiri yomwe imagwira ntchito pafupipafupi mpaka 80 MHz.Cortex-M4 core imakhala ndi Floating point unit (FPU) yolondola imodzi yomwe imathandizira malangizo onse a Arm® single-processing data-processing ndi mitundu ya data.Imagwiritsanso ntchito malangizo onse a DSP ndi gawo loteteza kukumbukira (MPU) lomwe limakulitsa chitetezo cha pulogalamu.
Zipangizo za STM32L451xx zimayika zikumbukiro zothamanga kwambiri (Flash memory mpaka 512 Kbyte, 160 Kbyte ya SRAM), mawonekedwe a Quad SPI Flash memory (omwe akupezeka pamaphukusi onse) komanso ma I/O owonjezera ndi zotumphukira zolumikizidwa ndi mabasi awiri a APB. , mabasi awiri a AHB ndi matrix a 32-bit multi-AHB.
Zipangizo za STM32L451xx zimaphatikizira njira zingapo zodzitchinjiriza zophatikizidwa ndi Flash memory ndi SRAM: chitetezo chowerengera, chitetezo cholemba, chitetezo chowerengera ma code ndi Firewall.
Zipangizozi zimapereka 12-bit ADC (5 Msps), zofananira ziwiri, amplifier imodzi, njira imodzi ya DAC, buffer yamkati yamagetsi, RTC yotsika mphamvu, 32-bit timer, imodzi 16-bit. PWM timer yodzipereka pakuwongolera magalimoto, zowerengera nthawi zinayi za 16-bit, ndi zowerengera ziwiri za 16-bit low-power time.
Kuphatikiza apo, mpaka 21 capacitive sensing channels zilipo.
Amakhalanso ndi njira zoyankhulirana zokhazikika komanso zapamwamba, zomwe ndi ma I2C anayi, ma SPI atatu, ma UART atatu, UART imodzi ndi UART imodzi yotsika kwambiri, SAI imodzi, SDMMC imodzi, CAN imodzi.
STM32L451xx imagwira ntchito mu -40 mpaka +85 °C (+105 °C mphambano) ndi -40 mpaka +125 °C (+130 °C junction) kutentha kumayambira pa 1.71 mpaka 3.6 V magetsi.Mitundu yambiri yopulumutsa mphamvu imapangitsa kupanga mapangidwe amagetsi otsika mphamvu.
Mphamvu zina zodziyimira pawokha zimathandizidwa: zolowetsa zodziyimira pawokha za analogi za ADC, DAC, OPAMP ndi zofananira.Kulowetsa kwa VBAT kumapangitsa kuti zitheke kusunga RTC ndi zolembetsa zosunga zobwezeretsera.
Banja la STM32L451xx limapereka mapaketi asanu ndi limodzi kuchokera pamaphukusi 48 mpaka 100.
