lpc2114fbd64单片机

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.
• in-system programming (isp) and in-application programming (iap) via on-chip bootloader software. flash programming takes 1 ms per 512 b line. single sector or full chip erase takes 400 ms.
• embeddedice-rt interface enables breakpoints and watch points. interrupt service routines can continue to execute whilst the foreground task is debugged with the on-chip realmonitor software.
• embedded trace macrocell (etm) enables non-intrusive high speed real-time tracing of instruction execution.
• four-channel 10-bit adc with conversion time as low as 2.44 us.
• two 32-bit timers (with four capture and four compare channels), pwm unit (six outputs), real-time clock (rtc) and watchdog.
• multiple serial interfaces including two uarts (16c550), fast i²c-bus (400 kbit/s) and two spis.
• 60 mhz maximum cpu clock available from programmable on-chip phase-locked loop with settling time of 100 us.
• vectored interrupt controller with configurable priorities and vector addresses.
• up to forty-six 5 v tolerant general purpose i/o pins. up to nine edge or level sensitive external interrupt pins available.
• 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系列基于一个支持实时仿真和跟踪的16/32位arm7tdmi-s cpu,并带有128/256 k字节(kb)嵌入的高速flash存储器。128位宽度的存储器接口和独特的加速结构使32位代码能够在最大时钟速率下运行。对代码规模有严格控制的应用可使用16位thumb模式将代码规模降低超过30%,而性能的损失却很小。
  由于lpc2100系列采用非常小的64脚封装、极低的功耗、多个32位定时器、4路10位adc、pwm输出以及多达9个外部中断,这使它们特别适用于工业控制、医疗系统、访问控制和电子收款机(pos)等应用领域。由于内置了宽范围的串行通信接口,它们也非常适合于通信网关、协议转换器、嵌入式软件调制解调器以及其它各种类型的应用。后续的器件还将以太网、802.11以及usb功能。
