key features brought by lpc2114/2124/01 devices

• fast gpio ports enable port pin toggling up to 3.5 times faster than the original device. they also allow for a port pin to be read at any time regardless of its function.
• dedicated result registers for adc(s) reduce interrupt overhead. the adc pads are 5 v tolerant when configured for digital i/o function(s).
• uart0/1 include fractional baud rate generator, auto-bauding capabilities and handshake flow-control fully implemented in hardware.
• buffered ssp serial controller supporting spi, 4-wire ssi, and microwire formats.
• spi programmable data length and master mode enhancement.
• diversified code read protection (crp) enables different security levels to be implemented. this feature is available in lpc2114/2124/00 devices as well.
• general purpose timers can operate as external event counters.

key features common for all devices

• 16/32-bit arm7tdmi-s microcontroller in a tiny lqfp64 package.
• 16 kb on-chip static ram.
• 128/256 kb on-chip flash program memory. 128-bit wide interface/accelerator enables high speed 60 mhz operation.

• on-chip crystal oscillator with an operating range of 1 mhz to 30 mhz.
• two low power modes, idle and power-down.
• processor wake-up from power-down mode via external interrupt.
• individual enable/disable of peripheral functions for power optimization.
• dual power supply:
  • cpu operating voltage range of 1.65 v to 1.95 v (1.8 v +- 0.15 v).
  • i/o power supply range of 3.0 v to 3.6 v (3.3 v +- 10 pct) with 5 v tolerant i/o pads. 16/32-bit arm7tdmi-s processor.

  lpc2100系列基于一個支持實時仿真和跟蹤的16/32位arm7tdmi-s cpu,并帶有128/256 k字節(jié)(kb)嵌入的高速flash存儲器。128位寬度的存儲器接口和獨(dú)特的加速結(jié)構(gòu)使32位代碼能夠在最大時鐘速率下運(yùn)行。對代碼規(guī)模有嚴(yán)格控制的應(yīng)用可使用16位thumb模式將代碼規(guī)模降低超過30%,而性能的損失卻很小。
  由于lpc2100系列采用非常小的64腳封裝、極低的功耗、多個32位定時器、4路10位adc、pwm輸出以及多達(dá)9個外部中斷,這使它們特別適用于工業(yè)控制、醫(yī)療系統(tǒng)、訪問控制和電子收款機(jī)(pos)等應(yīng)用領(lǐng)域。由于內(nèi)置了寬范圍的串行通信接口,它們也非常適合于通信網(wǎng)關(guān)、協(xié)議轉(zhuǎn)換器、嵌入式軟件調(diào)制解調(diào)器以及其它各種類型的應(yīng)用。后續(xù)的器件還將以太網(wǎng)、802.11以及usb功能。
