Chithunzi cha LPC2378FBD144K IC MCU 16/32B 512KB FLSH 144LQFP

Kufotokozera

Ma microcontrollers a LPC2377/78 amachokera ku 16-bit / 32-bit ARM7TDMI-S CPU yokhala ndi nthawi yeniyeni yomwe imaphatikiza microcontroller ndi 512 kB ya kukumbukira kwapamwamba kwambiri.Mawonekedwe a 128-bit wide memory memory ndi mawonekedwe apadera a accelerator amathandizira kupha ma code 32-bit pamlingo wokwera kwambiri.Kuti mugwire ntchito movutikira pakadumphadumpha pazantchito ndi ma aligorivimu a DSP, izi zimakulitsa magwiridwe antchito mpaka 30 % pamayendedwe a Thumb.Pogwiritsa ntchito ma code ovuta kwambiri, njira ina ya 16-bit Thumb imachepetsa kachidindo ndi 30% ndi chilango chochepa.Ma LPC2377/78 ndi abwino pamapulogalamu olumikizirana amitundu yambiri.Zimaphatikizapo 10/100 Ethernet Media Access Controller (MAC), chipangizo chothamanga cha USB chokhala ndi 4 kB ya endpoint RAM (LPC2378 yokha), ma UART anayi, ma CAN awiri (LPC2378 okha), mawonekedwe a SPI, ma Synchronous Serial Ports (SSP). ), maulendo atatu a mabasi a I2C, mawonekedwe a I 2S-bus, ndi External Memory Controller (EMC).Kuphatikizika kwa maulalo olumikizirana ophatikizika ndi cholumikizira chamkati cha 4 MHz, SRAM cha 32 kB, 16 kB SRAM cha Efaneti, 8 kB SRAM ya USB ndi ntchito zina zonse, pamodzi ndi SRAM yoyendetsedwa ndi batire ya 2 kB imapangitsa chipangizochi kukhala choyenera zipata zolumikizirana ndi ma protocol converters.Zowerengera zosiyanasiyana za 32-bit, 10-bit ADC, 10-bit DAC, PWM unit, CAN control unit, mpaka mizere yofulumira ya 104 ya GPIO yokhala ndi mpaka 50 m'mphepete mpaka mapini anayi osokoneza akunja amapanga ma microcontroller awa. oyenera kuwongolera mafakitale ndi machitidwe azachipatala.
