♠ Mphamvu zotsika kwambiri za Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, mpaka 256KB Flash, 64KB SRAM, analogi, mawu

Zipangizo za STM32L431xx ndi ma microcontrollers omwe ali ndi mphamvu yochepa kwambiri yochokera ku 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 yogwiritsira ntchito, njira ziwiri za DAC, buffer yamkati yamagetsi, RTC yamphamvu yochepa, nthawi imodzi ya 32-bit, imodzi ya 16-bit. PWM timer yodzipereka pakuwongolera magalimoto, zowerengera nthawi zinayi za 16-bit, ndi zowerengera ziwiri za 16-bit low-power time.
