单片机姓“单”,SoC即片上系统才是主要的技术发展方向,只有将整个系统都集成在一个集成电路芯片上,才能做到低成本、高可靠性。当前单片机技术世界主要发展的潮流是微功耗(一个钮扣电池可以工作几年),***的芯片体积(大量采用QFN,VFBGA,WLCSP等等这样的超小型封装),SV015iG5-4多种通讯和网络(包括无线网络)收发控制等功能完全内置,目前SOC技术和SIP技术,甚至要将已经很少的滤波电容和高频匹配电路和晶体等,也集成到芯片内部,这样的单片机才是真正的单片机。有这样一个实例,一个可能2CMX2CM的小小的电路板,上面几乎没有如何外加零件,只有一个电池,一个单片机,但是确实是一个完整的,功能强大的,具有ZigBee无线网络功能的嵌入式系统。另一误区是对使用仿真器褒贬。有人讲单片机教学开发没有必要使用仿真器。也有很多国内公司,目前仍然在卖力的推广那种高价格的”通用”仿真器,我们认为,从单片机仿真器的世界发展趋势看,单片机教学,不仅需要,而且完全有可能装备得起仿真器,保证每个学生有一台。LS产电,可编程控制器,变频器,输入输出模块,欢迎咨询,这是因为,SOC技术的发展,使几乎所有的单片机生产制造商,都在目前使用的新型单片机中,内置了仿真器的功能(这相当于将价格高昂和复杂地仿真器功能,集成制造在SOC内部,因为在硅片上集成仿真器的成本很低,基本上可以忽略不计,所以,在芯片上集成了仿真器功能后,并不影响单片机成本),这些仿真器都是采用类似JTAG仿真的功能。具有强大的调试功能,仿真时无需要将单片机移除,就可以在KEIL和IAR这样通用编译环境下,实现单步,断点,C语言源级调试等***功能,这样的***调试功能,无论是对单片机初学者或者是对开发比较复杂的应用软件,都是必须要的东西。采用这样内置JTAG的仿真器,除了无须那些大型昂贵的通用仿真器外。另外一个重要优势是,无论仿真调试和FLASH***,都只需要1-3个I/O口线就可以实现,这对于新型小型封装单片机而言。既不需要昂贵的特殊仿真插头插座,也容易实现在应用编程和代码更新,调试等功能。再一个误区是对汇编语言的看法,这一点其实已经不需要争议。在单片机教学中。SV015iG5-4放弃汇编,完全以C语言进行编程,是大势所趋。无论是ARM还是8051,目前C语言编程基本上都可以完全可以取代原来需要汇编的地方。目前比较新的单片机芯片,在厂商技术支持和应用代码样板中。都已经基本完全放弃了汇编代码。GMC-600/4GMC-800/4GMD-9/4GMD-12/4GMD-18/4GMD-22/4GMD-32/4GMD-40/4GMD-50/4GMD-65/4GMD-75/4GMD-85/4型号GMC-9×(2)AR-9GMC-12×(2)AR-9GMC-18×(2)AR-9GMC-22×(2)AR-9GMC-32×(2)AR-9GMC-40×(2)AR-9GMC-50×(2)AR-9GMC-65×(2)AR-9GMC-75×(2)AR-9GMC-85×(2)AR-9GMC-100×(2)AR-100GMC-125×(2)AR-100GMC-150×(2)AR-100GMC-180×(2)AR-180GMC-220×(2)AR-180GMC-300×(2)AR-180GMC-400×(2)AR-180GMD-9×(2)AR-9GMD-12×(2)AR-9GMD-18×(2)AR-9GMD-22×(2)AR-9GMD-32×(2)AR-9GMD-40×(2)ABL203aIN50,63,100,150,225AABL403bIN300,350,400AABL803bIN400,500,600AABL803bIN700,800AGBL103IN"1.6,3.2,6.3,12,20,32,50,63,100A"GBL203IN63,100,160,200,250ABKN1P+N40A6KA230/400VACBKN1P+N50,63A4.5KA230/400VACBKN2P1,2,3,4,6,10,16,20,25,32A6KA230/400VACBKN2P40A6KA230/400VACBKN2P50,63A4.5KA230/400VACBKN3P1,2,3,4,6,10,16,20,25,32A6KA230/400VACBKN3P40A6KA230/400VACBKN3P50,63A4.5KA230/400VACBKN3P+N1,2,3,4,6,10,16,20,25,32A6KA230/400VACBKN3P+N40A6KA230/400VACBKN3P+N50,63A4.5KA230/400VACBKN4P1,2,3,4,6,10,16,20,25,32A6KA230/400VACBKN4P40A6KA230/400VACBKN4P50,63A4.5KA230/400VACAX用于BKNBKH1P63,80,100A10KA230VACBKH1P+N63,80,100A10KA230/400VACBKH2PBKH3PBKH3P+NBKH4PBKP1P+N2,4,6,10,16,20,32A3KA230VACBKM1P6KA230VACBKM2P2,4,6,10,16,20,25,32,40,50A6KA230/400VACBKM3P6KA230/400VACRH11(AL)用于BKMNHI11(AX)用于BKMBS32a2P6,10,15,20,30A1.5KA110/220VAC剩余电流断路器型号极数额定电流分断能力额定剩余电流RKN2P25,32,40A-30,100,300mARKN2P63ARKN4P25,32,40ARKN4P63ARKP1P+N2,4,6,10,16,20,32A3KA230VAC15,30,100,300mA32KGRa2P15,20,30A1.5KA220VAC15,30mA隔离开关型号极数额定电流BKD1P63,80,100ABKD2PBKD3PBKD4P塑壳断路器产品型号极数分断能力额定电流(AC380V)SV015iG5-4经济型ABE52b2P7.5KA5,10,15,20,30,40,50AABE53b3PABE62b2P7.5KA60AABE63b3PABE102b2P14KA5,10,15,20,30,ABE103b3P40,50,60,75,100AABE104b4PABE202b2P18KA100,125,150,ABE203b3P175,200,225AABE204b4PABE402a2P25KA250,300,350,400AABE403a3PABE404a4PABE802a2P35KA500,600AABE803a3PABE804a4PABE802a2P35KA700,800AABE803a3PABE804a4P标准型ABS32b2P7.5KA5,10,15,20,30AABS33b3PABS52b2P14KA5,10,15,20,30,40,50AABS53b3PABS54b4PABS62b2P14KA60AABS63b3PABS64b4PABS102b2P25KA15,20,30,40,ABS103b3P50,60,75,100AABS104b4PABS202b2P25KA100,125,150,ABS203b3P175,200,225AABS204b4PABS402a2P35KA250,300,350,400AABS403a3PABS404a4PABS802a2P50KA500,600AABS803a3PABS804a4PABS802a2P50KA700,800AABS803a3PABS804a4PABS10033P65KA1000AABS12033P65KA1200A高分断型ABH32b2P14KA5,10,15,20,30AABH33b3PABH52b2P25KA15,20,30,40,50AABH53b3PABH54b4PABH102b2P35KA15,20,30,40,ABH103b3P50,60,75,100AABH104b4PABH202b2P35KA100,125,150,ABH203b3P175,200,225AABH204b4PABH402a2P50KA250,300,350,400AABH403a3PABH404a4P限流型ABL52a2P65KA15,20,30,40,50AABL53a3PABL54a4PABL102a2P65KA15,20,30,40,ABL103a3P50,60,75,100AABL104a4PABL202a2P65KA100,125,150,ABL203a3P175,200,225AABL204a4PABL402a2P65KA250,300,350,400AABL403a3PABL404a4PABL802a2P65KA500,600AABL803a3PABL804a4PABL802a2P65KA700,800AABL803a3PABL804a4P(AC380V)标准型GBN522P35KA16,20,25,32,40,50AGBN533PGBN544PGBN1022P35KA63,80,100AGBN1033PGBN1044PGBN2022P35KA125,160,200,250AGBN2033PGBN2044P高分断型GBH522P50KA16,20,25,32,40,50AGBH533PGBH544PGBH1022P63,80,100AGBH1033P50KAGBH1044PGBH2022P125,160,200,250AGBH2033P50KAGBH2044P限流型GBL522P16,20,25,32,40,50AGBL533P85KAGBL544PGBL1022P63,80,100AGBL1033P85KAGBL1044PGBL2022P125,160,200,250AGBL2033P85KAGBL2044P从新解读“授之以鱼不如授之以渔”的含意,提到目前单片机教学现状,有人往往搬出“授之以鱼不如授之以渔”这个俗话来。讲我们目前的单片机教学内容如此经典和陈旧,那是因为我们目前的单片机教学主要是是“授之以渔”,授之以解决问题的方法,培养解决问题的能力,是引导学生入门。)
