Chithunzi cha STM32L431CCT6 IC MCU 32BIT 256KB FLASH 48LQFP

Kufotokozera

Zipangizo za STM32L431xx ndi ma microcontrollers omwe ali ndi mphamvu yochepa kwambiri yotengera Arm® Cortex®-M4 32-bit RISC core 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.Zida za STM32L431xx zimayika zikumbukiro zothamanga kwambiri (Flash memory mpaka 256 Kbyte, 64 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 STM32L431xx zimaphatikizira njira zingapo zodzitchinjiriza zophatikizidwa ndi Flash memory ndi SRAM: chitetezo chowerengera, chitetezo cholemba, chitetezo chowerengera ma code ndi Firewall.Zipangizozi zimakhala ndi 12-bit ADC (5 Msps), zofananira ziwiri, amplifier imodzi, njira ziwiri za DAC, buffer yamkati yamagetsi, RTC yotsika mphamvu, nthawi imodzi ya 32-bit, 16-bit PWM timer. odzipereka ku kuwongolera magalimoto, zowonera 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 zolumikizirana zokhazikika komanso zapamwamba.• Ma I2C atatu • Ma SPI atatu • Ma UART atatu ndi UART ya Mphamvu Zochepa imodzi.• SAI imodzi (Serial Audio Interfaces) • SDMMC Imodzi • Imodzi Ikhoza • One SWPMI (Single Wire Protocol Master Interface) STM32L431xx imagwira ntchito mu mphambano ya -40 mpaka +85 °C (+105 °C), -40 mpaka +105 ° C (+125 °C mphambano) ndi -40 mpaka +125 °C (+130 °C mphambano) kutentha kumachokera pa 1.71 mpaka 3.6 V magetsi.Mitundu yambiri yopulumutsira mphamvu imalola kupanga mapulogalamu otsika mphamvu.Mphamvu zina zodziyimira pawokha zimathandizidwa: zolowetsa zodziyimira pawokha za analogi za ADC, DAC, OPAMP ndi zofananira.Kulowetsa kwa VBAT kumalola kusunga RTC ndi zolembera zosunga zobwezeretsera.Banja la STM32L431xx limapereka mapaketi asanu ndi anayi kuchokera pamaphukusi 32 mpaka 100-pini.
