LPC3250FET296/01,5 IC MCU 16/32BIT ROMLESS 296TFBGA

Kufotokozera

Ma microcontrollers ophatikizidwa a LPC3220/30/40/50 adapangidwa kuti akhale ndi mphamvu zochepa, ntchito zogwira ntchito kwambiri.NXP idakwaniritsa zolinga zawo pogwiritsa ntchito njira ya 90 nanometer kukhazikitsa maziko a ARM926EJ-S CPU okhala ndi purosesa yoyendera vekitala komanso zotumphukira zambiri kuphatikiza USB On-The-Go.LPC3220/30/40/50 imagwira ntchito pa CPU pafupipafupi mpaka 266 MHz.Kukhazikitsa kwa NXP kumagwiritsa ntchito maziko a ARM926EJ-S CPU okhala ndi kamangidwe ka Harvard, mapaipi a magawo 5, komanso Memory Management Unit (MMU).MMU imapereka mphamvu zokumbukira zomwe zimafunikira kuti zithandizire zofuna zamapulogalamu amakono.ARM926EJ-S ilinso ndi zida zopangira zowonjezera za DSP, zomwe zimaphatikizapo machitidwe a MAC amtundu umodzi, ndi machitidwe amtundu wa Jazelle Java Byte-code.Kukhazikitsa kwa NXP kuli ndi cache ya malangizo a 32 kB ndi cache ya data ya 32 kB.Pakugwiritsa ntchito mphamvu pang'ono, LPC3220/30/40/50 imatenga mwayi pakukula kwaukadaulo wapamwamba wa NXP kukulitsa mphamvu zamkati ndikugwiritsa ntchito mapulogalamu owongolera zomangamanga kuti akwaniritse kasamalidwe ka mphamvu zamagetsi.LPC3220/30/40/50 imaphatikizaponso 256 kB ya on-chip static RAM, mawonekedwe a NAND flash, Ethernet MAC, LCD controller yomwe imathandizira mapanelo a STN ndi TFT, ndi mawonekedwe akunja a basi omwe amathandiza SDR ndi DDR SDRAM monga komanso zida zosasunthika.Kuphatikiza apo, LPC3220/30/40/50 imaphatikizapo mawonekedwe a USB 2.0 othamanga, ma UART asanu ndi awiri, malo awiri a mabasi a I2C, madoko awiri a SPI/SSP, ma I2S-mabasi awiri, ma PWM awiri otulutsa, PWM yowongolera mota. , zowerengera zaka zisanu ndi chimodzi zokhala ndi zolowetsa ndikuyerekeza zotuluka, mawonekedwe a Secure Digital (SD), ndi 10-bit Analog-to-Digital Converter (ADC) yokhala ndi njira yolumikizira pazenera.
