恩智浦半導體(NXP Semiconductors N.V.;NASDAQ:NXPI)今天宣佈推出業界最佳性能的ARM® Cortex™-M3微控制器。
LPC1800的低功耗最佳化設計,使其在Flash或RAM中的極低頻率到150Mhz的範圍中,均可發揮最大化的性能。此性能為廣大的需求應用提供了最多的連接和頻寬的選擇。靈活的雙組256位元Flash記憶體支援讀、寫操作,可保存「黃金副本(golden copy)」,防止在重新編程中出現失誤,也可以簡單地成為單儲存位元使用。LPC1800也支援兩種最新週邊設備:靈活的四路SPI介面和可配置計時器子系統。
Standard features on all members of the series include 32 KB ROM containing boot code and on-chip software drivers, eight-channel General-Purpose DMA (GPDMA) controller, two 10-bit ADCs and 10-bit DAC with data conversion rate of 400k samples/s, a motor Control PWM and Quadrature Encoder Interface, 4 UARTs, 2 Fast-mode Plus I2C, I2S, 2 SSP/SPI, Smart card interface, 4 timers, windowed watchdog timer, an alarm timer, an ultra-low power RTC with 256 bytes of battery powered backup registers and up to 80 general purpose I/O pins.
封装:144-pin and 208-pin LQFP packages and 100-pin, 180-pin and 256-pin BGA packages。
