Tlhaloso

Lisebelisoa tsa STM32L452xx ke li-microcontrollers tse tlase-tlase tse thehiloeng holim'a setsi sa Arm® Cortex®-M4 32-bit RISC se sebetsang ka lebelo ho fihla ho 80 MHz.Cortex-M4 ea mantlha e na le yuniti ea Floating point (FPU) e nepahetseng e le 'ngoe e ts'ehetsang litaelo tsohle tsa Arm® tse nepahetseng tsa ts'ebetso ea data le mefuta ea data.E boetse e sebelisa sete e felletseng ea litaelo tsa DSP le yuniti ea ts'ireletso ea memori (MPU) e matlafatsang ts'ireletso ea ts'ebeliso.Lisebelisoa tsa STM32L452xx li kentse mehopolo ea lebelo le holimo (Flash memory ho fihla ho 512 Kbyte, 160 Kbyte ea SRAM), interface ea Quad SPI Flash memory interface (e fumanehang liphutheloana tsohle) le mefuta e mengata e ntlafalitsoeng ea li-I/O le li-peripheral tse hokahaneng le libese tse peli tsa APB. , libese tse peli tsa AHB le matrix a 32-bit a mangata a AHB.Lisebelisoa tsa STM32L452xx li kentse mekhoa e mengata ea tšireletso bakeng sa memori ea Flash e kentsoeng le SRAM: tšireletso ea ho bala, tšireletso ea ho ngola, tšireletso ea ho bala khoutu ea thepa le Firewall.Lisebelisoa li fana ka lebelo la 12-bit ADC (5 Msps), libapiso tse peli, amplifier e le 'ngoe ea ts'ebetso, mocha o le mong oa DAC, buffer ea ka hare ea motlakase, RTC ea matla a tlaase, timer e le' ngoe ea 32-bit, nako e le 'ngoe ea 16-bit PWM. e inehetseng ho taolo ea makoloi, li-timers tse 'ne tsa sepheo se akaretsang sa 16-bit, le lisebelisoa tse peli tsa nako e tlase tsa 16-bit.Ho feta moo, ho na le likanale tse fihlang ho 21 tsa capacitive sensing.Li boetse li na le li-interfaces tse tloaelehileng le tse tsoetseng pele tsa puisano, e leng li-I2C tse 'nè, li-SPI tse tharo, li-USART tse tharo, UART e le' ngoe le UART e le 'ngoe ea Low-Power UART, e le' ngoe ea SAI, SDMMC e le 'ngoe, e le' ngoe ea CAN, sesebelisoa se le seng sa USB se nang le lebelo le feletseng ka kristale.STM32L452xx e sebetsa ho -40 ho +85 °C (+105 °C junction) le -40 ho +125 °C (+130 °C junction) mocheso ho tloha ho 1.71 ho ea ho 3.6 VDD ea matla a VDD ha u sebelisa molaoli oa ka hare oa LDO. le phepelo ea motlakase ea 1.05 ho isa ho 1.32V VDD12 ha u sebelisa phepelo ea kantle ea SMPS.Sete e felletseng ea mekhoa ea ho boloka matla e etsa hore ho khonehe moralo oa lits'ebetso tsa matla a tlase.Lisebelisoa tse ling tse ikemetseng tsa motlakase lia tšehetsoa: phepelo e ikemetseng ea analog bakeng sa ADC, DAC, OPAMP le comparator.Kenyelletso ea VBAT e etsa hore ho khonehe ho boloka RTC le lirejistara tsa bekapo.Lisebelisoa tsa motlakase tse inehetseng tsa VDD12 li ka sebelisoa ho feta taolo ea kahare ea LDO ha e hokahantsoe le SMPS ea kantle.Lelapa la STM32L452xx le fana ka liphutheloana tse supileng ho tloha ho liphutheloana tse 48 ho isa ho tse 100.
