lpc900系列单片机 lpc900单片机是nxp(前身为philips)改进80c51结构，而得来的一系列性能卓越的高速51内核的单片机，相对80c51在性能与功能上有了很大的提升。当操作频率为12mhz时，除乘法和除法指令外，高速80c51 cpu的指令执行时间为167~333ns。同一时钟频率下，其速度为标准80c51器件的6倍。只需要较低的时钟频率即可达到同样的性能，这样无疑降低了功耗和emi | 型号 | ram | e2 | flash | icp/pp | isp/iap | tim | pwm | rtc | adc | dac | wd | uart | spi | i2c | i/o | 中断(外部) | 比较器 | 封装 | | p89lpc901 | 128b | - | 1k | y/- | - | 4 | 1ch. | √ | - | - | √ | - | - | - | 6 | 6(1) | 1 | so8 dip8 | | p89lpc902 | 128b | - | 1k | y/- | - | 4 | - | √ | - | - | √ | - | - | - | 6 | 6(1) | 2 | so8 dip8 | | p89lpc903 | 128b | - | 1k | y/- | - | 4 | - | √ | - | - | √ | √ | - | - | 6 | 9(1) | 2 | so8 | | p89lpc904 | 128b | - | 1k | y/- | - | 4 | - | √ | 4ch/8b | 1ch/8b | √ | √ | - | - | 6 | 9(1) | 2 | so8 dip8 | | p89lpc906 | 128b | - | 1k | y/- | - | 4 | 1ch. | √ | - | - | √ | - | - | - | 6 | 6(1) | 1 | so8 | | p89lpc907 | 128b | - | 1k | y/- | - | 4 | - | √ | - | - | √ | √ | - | - | 6 | 8(1) | 1 | so8 | | p89lpc908 | 128b | - | 1k | y/- | - | 4 | - | √ | - | - | √ | √ | - | - | 6 | 9(1) | 1 | so8 | | p89lpc9102 | 128b | - | 1k | y/- | - | 4 | 2ch. | √ | 4ch/8b | 1ch/8b | √ | - | - | - | 8 | 9(1) | 1 | hvson10 | | p89lpc9103 | 128b | - | 1k | y/- | - | 4 | - | √ | 4ch/8b | 1ch/8b | √ | √ | - | - | 8 | 9(1) | 1 | hvson10 | | p89lpc9107 | 128b | - | 1k | y/- | - | 4 | 2ch. | √ | 4ch/8b | 1ch/8b | √ | √ | - | - | 10 | 9(1) | 1 | tssop14 | | p89lpc912 | 128b | - | 1k | y/- | -y | 4 | 1ch. | √ | - | - | √ | - | √ | - | 12 | 7(1) | 2 | tssop14 | | p89lpc913 | 128b | - | 1k | y/- | -y | 4 | - | √ | - | - | √ | √ | √ | - | 12 | 10(1) | 2 | tssop14 | | p89lpc914 | 128b | - | 1k | y/- | -y | 4 | 1ch. | √ | - | - | √ | √ | √ | - | 12 | 10(1) | 2 | tssop14 | | p89lpc915 | 256b | - | 2k | y/- | -y | 4 | 1ch. | √ | 4ch/8b | 1ch/8b | √ | √ | - | √ | 12 | 13(3) | 2 | tssop14 | | p89lpc916 | 256b | - | 2k | y/- | -y | 4 | 1ch. | √ | 4ch/8b | 1ch/8b | √ | √ | √ | √ | 14 | 14(2) | 2 | tssop16 | | p89lpc917 | 256b | - | 2k | y/- | -y | 4 | 2ch. | √ | 4ch/8b | 1ch/8b | √ | √ | - | √ | 14 | 13(3) | 2 | tssop16 | | p89lpc920 | 256b | - | 2k | y/y | y/y | 4 | 2ch. | √ | - | - | √ | √ | - | √ | 18 | 12(3) | 2 | dip/tssop20 | | p89lpc921 | 256b | - | 4k | y/y | y/y | 4 | 2ch. | √ | - | - | √ | √ | - | √ | 18 | 12(3) | 2 | dip/tssop20 | | p89lpc922 | 256b | - | 8k | y/y | y/y | 4 | 2ch. | √ | - | - | √ | √ | - | √ | 18 | 12(3) | 2 | dip/tssop20 | | p89lpc924 | 256b | - | 4k | y/y | y/y | 4 | 2ch. | √ | 4ch/8b | 1ch/8b | √ | √ | - | √ | 18 | 12(3) | 2 | dip/tssop20 | | p89lpc925 | 256b | - | 8k | y/y | y/y | 4 | 2ch. | √ | 4ch/8b | 1ch/8b | √ | √ | - | √ | 18 | 12(3) | 2 | dip/tssop20 | | p89lpc930 | 256b | - | 4k | y/y | y/y | 4 | 2ch. | √ | - | - | √ | √ | √ | √ | 26 | 13(3) | 2 | tssop28 | | p89lpc931 | 256b | - | 8k | y/y | y/y | 4 | 2ch. | √ | - | - | √ | √ | √ | √ | 26 | 13(3) | 2 | tssop28 | | p89lpc932 | 768b | 512b | 8k | -/y | y/y | 4 | ccu | √ | - | - | √ | √ | √ | √ | 26 | 15(3) | 2 | plcc/tssop28 | | p89lpc932a1 | 768b | 512b | 8k | y/y | y/y | 4 | ccu | √ | - | - | √ | √ | √ | √ | 26 | 15(3) | 2 | plcc/tssop28 | | p89lpc933 | 256b | - | 4k | y/y | y/y | 4 | 2ch. | √ | 4ch/8bx2 | 1ch/8bx2 | √ | √ | √ | √ | 26 | 15(3) | 2 | tssop28 | | p89lpc934 | 256b | - | 8k | y/y | y/y | 4 | 2ch. | √ | 4ch/8bx2 | 1ch/8bx2 | √ | √ | √ | √ | 26 | 15(3) | 2 | tssop28 | | p89lpc935 | 768b | 512b | 8k | y/y | y/y | 4 | ccu | √ | 4ch/8bx2 | 1ch/8bx2 | √ | √ | √ | √ | 26 | 15(3) | 2 | plcc/tssop/hvqfn28 | | p89lpc936 | 768b | 512b | 16k | y/y | y/y | 4 | ccu | √ | 4ch/8bx2 | 1ch/8bx2 | √ | √ | √ | √ | 26 | 15(3) | 2 | tssop28 | | p89lpc938 | 768b | 512b | 8k | y/y | y/y | 4 | ccu | √ | 8ch/10b | - | √ | √ | √ | √ | 26 | 15(3) | 2 | plcc/tssop/hvqfn28 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lpc952 | 512b | 512b | 8k | y/y | y/y | 4 | 2ch | √ | 8ch/10bit | - | √ | 2 | - | √ | 42 | 17(3) | 2 | plcc44 |
