NXP發售LPC11U30 USB微控制器(128K快閃記憶體)

 2012-07-18

支援多種記憶體和封裝選擇的簡單易用、超低功耗ARM Cortex-M0 USB解決方案現已上市

恩智浦半導體NXP Semiconductors N.V. 近日宣佈推出基於ARM Cortex-M0處理器的簡單易用、功耗超低LPC11U30系列USB微控制器, 目前該系列產品已向全球各大經銷商鋪貨。從獲獎的LPC11U00系列4 KB EEPROM、12 KB SRAM,到恩智浦嵌入式128KB快閃記憶體(256位元組可讀寫),該系列產品有多種記憶體配置可供選擇。 此外,LPC11U30系列微控制器有效功耗僅為110 uA/MHz,可完美支援遊戲滑鼠、鍵盤、血糖儀、遙控玩具等USB2.0對大容量本機存放區的應用需求。



The LPC11U30 supports the latest USB 2.0 specification with Link Power Management (LPM) mode, which allows a device to enter a suspended state when not in use. It also offers on-chip power profiles optimized for specific power levels, including a Low Current mode ideal for battery-powered applications that only connect to USB for occasional charging or data download. With multiple USB drivers integrated into ROM, the LPC11U30 microcontroller maximizes flash memory utilization and provides fully tested APIs that enable easy USB integration, which can be further enhanced by using nxpUSBlib, NXP’s fully featured open source USB library.


Features
Key specifications for the LPC11U30 devices include:

  • ARM Cortex-M0 processor, up to 50 MHz
  • 40 KB to 128 KB Flash, up to 12 KB SRAM
  • 4 KB EEPROM
  • Integrated ROM drivers including Human Interface Device (HID), Mass Storage Device Class (MSC), and Communication Device Class (CDC)
  • Selectable USART with Smart Card Interface/UART, 2 SSP, I2C (Fm+)
  • 8-channel high-precision 10-bit ADC with ±1LSB DNL
  • Two 16-bit and two 32-bit timers with PWM/Match/Capture
  • 12 MHz internal RC oscillator with 1 percent accuracy over temperature and voltage
  • Up to 54 GPIOs
  • Packages include TFBGA48, HVQFN33 (5 mm x 5 mm and 7 mm x 7 mm), LQFP48/64


Availability
Product samples of LPC11U30 series microcontrollers are available now from NXP distributors and sample stores. Development boards for the LPC11U30 series are available immediately through Embedded Artists, which offers a QuickStart board based on the LPC11U35 in an HVQFN33 package, and through NGX Technologies, which offers a development board based on the LPC11U37 in an LQFP48 package.
