NXP发售LPC11U30 USB微控制器(128K闪存)

 2012-07-18

支持多种内存和封装选择的简单易用、超低功耗ARM Cortex-M0 USB解决方案现已上市


恩智浦半导体NXP Semiconductors N.V. 近日宣布推出基于ARM Cortex-M0处理器的简单易用、功耗超低LPC11U30系列USB微控制器, 目前该系列产品已向全球各大经销商铺货。从获奖的LPC11U00系列4 KB EEPROM、12 KB SRAM,到恩智浦嵌入式128KB闪存(256字节可擦写),该系列产品有多种内存配置可供选择。 此外,LPC11U30系列微控制器有效功耗仅为110 uA/MHz,可完美支持游戏鼠标、键盘、血糖仪、遥控玩具等USB2.0对大容量本地存储的应用需求。



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.
