♠ Ultra-low-power Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, a hiki i 128KB Flash, 40KB SRAM, analog, ext.SMPS

ʻO nā polokalamu STM32L412xx 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 STM32L412xx i nā hoʻomanaʻo kiʻekiʻe (Flash memory a hiki i 128 Kbyte, 40 Kbyte o SRAM), kahi Quad SPI Flash memory interface (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 mea STM32L412xx 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 ʻelua wikiwiki 12-bit ADC (5 Msps), ʻelua mea hoʻohālikelike, hoʻokahi amplifier hana, kahi RTC haʻahaʻa haʻahaʻa, hoʻokahi manawa 32-bit kumu nui, hoʻokahi manawa PWM 16-bit i hoʻolaʻa ʻia i ka mana kaʻa, ʻehā nui- manaʻo 16-bit timers, a me ʻelua 16-bit-mana haʻahaʻa timers.

Eia kekahi, hiki i ka 12 capacitive sensing channels i loaʻa.

Hōʻike pū lākou i nā pilina kamaʻilio maʻamau a me ka holomua, ʻo ia hoʻi ʻekolu I2C, ʻelua SPI, ʻekolu USARTs a me hoʻokahi UART Low-Power, hoʻokahi uila uila uila piha USB.

Hoʻohana ka STM32L412xx 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 VDD mana lako i ka wā e hoʻohana ai i loko o ka LDO regulator. a me kahi lako mana 1.00 a 1.32V VDD12 i ka wā e hoʻohana ai i ka lako SMPS waho.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, OPAMP a me ka mea hoʻohālikelike.Hiki i kahi hoʻokomo VBAT ke hiki ke hoʻopaʻa i ka RTC a me nā papa inoa hoʻopaʻa.Hiki ke hoʻohana ʻia nā lako mana VDD12 i hoʻolaʻa ʻia e kāʻalo i ka mea hoʻoponopono LDO kūloko ke hoʻopili ʻia i kahi SMPS waho.

Hāʻawi ka ʻohana STM32L412xx i ʻeono pūʻolo mai ka 32 a i ka 64-pin pūʻolo.
