♠ ʻO Arm® Cortex®-M4 32-bit MCU+FPU, 100 DMIPS, a hiki i 1 MB Flash, 320 KB SRAM, USB OTG FS, leo, SMPS waho
ʻO nā polokalamu STM32L496xx 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. Hōʻike ka Cortex-M4 core i kahi kiko kiko lana (FPU) kikoʻī hoʻokahi 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 STM32L496xx i nā mea hoʻomanaʻo kiʻekiʻe (a hiki i 1 Mbyte o ka hoʻomanaʻo Flash, 320 Kbyte o SRAM), kahi mea hoʻomanaʻo hoʻomanaʻo waho maʻalahi (FSMC) no nā hoʻomanaʻo hoʻomanaʻo (no nā hāmeʻa me nā pūʻolo o 100 mau pine a keu aku), kahi pānaʻi hoʻomanaʻo Quad SPI Flash (i loaʻa ma nā pūʻolo a pau) a me kahi peripheral pili i ʻelua mau ʻāpana APB a me ʻelua mau pānaʻi hoʻonui. Nā pahi kaʻa AHB a me kahi matrix bus 32-bit multi-AHB.
Hoʻokomo nā mea STM32L496xx 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 ʻekolu wikiwiki 12-bit ADCs (5 Msps), ʻelua mea hoʻohālikelike, ʻelua mau mea hoʻonui hana, ʻelua mau kahawai DAC, kahi pahu kuhikuhi voli i loko, kahi RTC haʻahaʻa haʻahaʻa, ʻelua mau manawa 32-bit kumu nui, ʻelua mau manawa PWM 16-bit i hoʻolaʻa ʻia no ka hoʻokele kaʻa, ʻehiku mau mana 16-bit timers-bit haʻahaʻa. Kākoʻo nā mea hana i nā kānana kikohoʻe ʻehā no nā modulators delta sigma waho (DFSDM).
Eia kekahi, hiki i ka 24 capacitive sensing channels i loaʻa. Hoʻokomo pū nā mea hana i kahi mea hoʻokele LCD i hoʻohui ʻia 8x40 a i ʻole 4x44, me ka mea hoʻololi hoʻololi i loko.
Hōʻike pū lākou i nā pilina kamaʻilio maʻamau a holomua, ʻo ia hoʻi ʻehā I2C, ʻekolu SPI, ʻekolu USART, ʻelua UART a me hoʻokahi UART Low-Power, ʻelua SAI, hoʻokahi SDMMC, ʻelua CAN, hoʻokahi USB OTG piha-wikiwiki, hoʻokahi SWPMI (hoʻokahi wire protocol master interface), kahi kiʻi kiʻi kiʻi a me ka DMA2D controller.
Hoʻohana ka STM32L496xx ma ka -40 a +85 °C (+105 °C junction), -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 ka 1.05 a i ka 1.32V waho mana lako mana VDD SMP2. Hiki ke hoʻolālā ʻia nā noi haʻahaʻa haʻahaʻa i kahi hoʻonohonoho piha o nā ʻano hoʻopakele mana.
Kākoʻo ʻia kekahi mau lako mana kūʻokoʻa: hoʻokomo kūʻokoʻa kūʻokoʻa analog no ADC, DAC, OPAMPs a me nā mea hoʻohālikelike, 3.3 V hoʻolaʻa lako hoʻokomo no ka USB a hiki i ka 14 I/Os hiki ke hoʻolako kūʻokoʻa a hiki i ka 1.08 V. ʻO kahi hoʻokomo VBAT hiki ke hoʻihoʻi 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 STM32L496xx i ʻehiku pūʻolo mai 64-pin a hiki i 169-pin pūʻolo.
