原创 LPC2132与AT91SAM64比较

现在ARM越来越多,现针对NXP和ATMEL公司的相同价位的AM7进比较:

NXP(philips) LPC2132 和ATMEL AT91SAM64用的比较多,批量价格在30元左右.

一,两款芯片的相同点:

1,Flash 64K,RAM:16K;

2,UART:2

3,ADC :8

4,RTC : 1

6,WDT: 1

3,封装:LQFP64

二,相同点:

                             LPC2132                                    AT91SAM64

Clock Speed(Mhz)         60                                                      55

SPI                                2                                                    1

I2C                                2                                                    1

TIME:                           2                                                     3

DAC                            1                                                     0

USB                             0                                                     1

SSC                             0                                                     1

DMA                           0(FIFO16B)                                   11(set by Myself)

EMC                           4级                                            不详(没做过试验)

1,AT91SAM64 的DMA 在大批量数据传输上节省大量时间.

2,USB接口也是一靓点.

 3,LPC2132的Flash是高速,可以跑50多MHz,AT91SAM64 就远远不及了
