♠ Mphamvu zotsika kwambiri za Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, mpaka 128KB Flash, 40KB SRAM, analogi, ext.SPS
Zipangizo za STM32L412xx 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 STM32L412xx zimayika zokumbukira zothamanga kwambiri (Flash memory mpaka 128 Kbyte, 40 Kbyte ya SRAM), mawonekedwe a Quad SPI Flash memory (omwe akupezeka pamaphukusi onse) komanso ma I/O opitilira muyeso ndi zotumphukira zolumikizidwa ndi mabasi awiri a APB. , mabasi awiri a AHB ndi matrix a 32-bit multi-AHB.
Zipangizo za STM32L412xx zimaphatikizira njira zingapo zodzitchinjiriza zophatikizidwa ndi Flash memory ndi SRAM: chitetezo chowerengera, chitetezo cholembera, chitetezo chowerengera code code ndi Firewall.
Zipangizozi zimakhala ndi ma 12-bit ADC (5 Msps) awiri othamanga, ofananira awiri, amplifier imodzi, RTC yamphamvu yochepa, chowerengera chimodzi cha 32-bit, chowerengera cha 16-bit PWM chodzipereka pakuwongolera magalimoto, zinayi zonse- cholinga 16-bit timer, ndi ziwiri 16-bit low-power timer.
Kuphatikiza apo, mpaka 12 capacitive sensing njira zilipo.
Amakhalanso ndi njira zoyankhulirana zokhazikika komanso zapamwamba, zomwe ndi ma I2C atatu, ma SPI awiri, ma UART atatu ndi UART imodzi yotsika kwambiri, chipangizo chimodzi cha USB chodzaza ndi liwiro chocheperako.
STM32L412xx imagwira ntchito mu -40 mpaka +85 °C (+105 °C mphambano) ndi -40 mpaka +125 °C (+130 °C makulidwe) kutentha kumayambira pa 1.71 mpaka 3.6 VDD magetsi a VDD mukamagwiritsa ntchito chowongolera chamkati cha LDO. ndi magetsi a 1.00 mpaka 1.32V VDD12 mukamagwiritsa ntchito ma SMPS akunja.Mitundu yambiri yopulumutsa mphamvu imapangitsa kupanga mapangidwe amagetsi otsika mphamvu.
Mphamvu zina zodziyimira pawokha zimathandizidwa: zolowetsa zodziyimira pawokha za analogi za ADC, OPAMP ndi comparator.Kulowetsa kwa VBAT kumapangitsa kuti zitheke kusunga RTC ndi zolembetsa zosunga zobwezeretsera.Zida zamagetsi zodzipatulira za VDD12 zitha kugwiritsidwa ntchito kudutsa chowongolera chamkati cha LDO mukalumikizidwa ndi SMPS yakunja.
Banja la STM32L412xx limapereka mapaketi asanu ndi limodzi kuchokera pamaphukusi 32 mpaka 64-pini.
