♠ ʻO Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, a hiki i 512KB Flash, 160KB SRAM, analog, leo
ʻO nā polokalamu STM32L451xx nā microcontrollers ultra-low-power e pili ana i ka hana kiʻekiʻe Arm® Cortex®-M4 32-bit RISC core e hana ana ma ke alapine a hiki i 80 MHz.Hāʻawi ka Cortex-M4 core i kahi kikoʻi Floating point unit (FPU) e kākoʻo ana i nā ʻōlelo aʻoaʻo a me nā ʻano ʻikepili āpau o Arm®.Hoʻokomo pū ia i kahi pūʻulu piha o nā ʻōlelo aʻoaʻo DSP a me kahi ʻāpana pale hoʻomanaʻo (MPU) e hoʻonui ai i ka palekana noi.
Hoʻokomo nā mea STM32L451xx i nā hoʻomanaʻo kiʻekiʻe (Flash memory a hiki i 512 Kbyte, 160 Kbyte o SRAM), kahi Quad SPI Flash hoʻomanaʻo hoʻomanaʻo (loaʻa ma nā pūʻolo āpau) a me kahi ākea o nā I/Os i hoʻonui ʻia a me nā peripheral pili i ʻelua mau pahi APB , ʻelua mau kaʻa kaʻa AHB a me kahi matrix kaʻaahi 32-bit multi-AHB.
Hoʻokomo nā polokalamu STM32L451xx i kekahi mau mea pale no ka hoʻomanaʻo Flash i hoʻokomo ʻia a me SRAM: pale heluhelu, pale kākau, pale helu helu helu proprietary a me Firewall.
Hāʻawi nā hāmeʻa i kahi wikiwiki 12-bit ADC (5 Msps), ʻelua mea hoʻohālikelike, hoʻokahi mea hoʻonui hana, hoʻokahi kahawai DAC, kahi pahu kuhikuhi uila kūloko, RTC haʻahaʻa haʻahaʻa, hoʻokahi manawa 32-bit kumu nui, hoʻokahi 16-bit. Hoʻolaʻa ʻia ka manawa PWM i ka mana kaʻa, ʻehā mau manawa 16-bit kumu nui, a me ʻelua mau manawa mana haʻahaʻa 16-bit.
Eia kekahi, hiki i ka 21 capacitive sensing channels i loaʻa.
Hōʻike pū lākou i nā pilina kamaʻilio maʻamau a holomua, ʻo ia hoʻi ʻehā I2C, ʻekolu SPI, ʻekolu USART, hoʻokahi UART a me hoʻokahi UART Low-Power, hoʻokahi SAI, hoʻokahi SDMMC, hoʻokahi CAN.
Ke hana nei ka STM32L451xx ma ka -40 a +85 °C (+105 °C junction) a me -40 a +125 °C (+130 °C junction) mai kahi 1.71 a 3.6 V mana lako.Hiki ke hoʻolālā ʻia nā noi mana haʻahaʻa i kahi pūʻulu piha o nā ʻano hoʻopakele mana.
Kākoʻo ʻia kekahi mau lako mana kūʻokoʻa: hoʻokomo kūʻokoʻa kūʻokoʻa analog no ADC, DAC, OPAMP a me nā mea hoʻohālikelike.Hiki i kahi hoʻokomo VBAT ke hiki ke hoʻopaʻa i ka RTC a me nā papa inoa hoʻopaʻa.
Hāʻawi ka ʻohana STM32L451xx i ʻeono mau pūʻolo mai ka 48 a hiki i nā pūʻolo 100-pin.
