问 有一个项目,因为PCB板尺寸比较小,用裸片又有一定的困难.因此想用SOP14或SOP16封装最少带2路ADC转换的单片机.请各位大虾帮帮手!!在此谢谢!! 答 1: 太多了SAMSUNG、HYNIX、MICROCHIP、FREESCALE等都有，你可以自己去选一款。 答 2: 带2路AD转换,14/16脚封装的单片机SAMSUNG的我查过，S3C1/S3C7系列和S3C8/S3C9系列并没有符合条件的。
Microchip我也查过了。HYNIX和FreeScall我去查一下。谢谢！！ 答 3: reHT系列 答 4: AD7528JR 如何  有SOP 跟 DIP的 答 5: C8051F330,MLP20,体积很小http://www.xhl.com.cn/xxzn/xxzn.asp 答 6: 用AVR的啊，HT的也可以啊！ 答 7: 谢谢谢谢,各位大虾的帮忙!! 答 8: ht46r51 dip18http://www.holtek.com.cn/china/products/mcu_6.htm

Note: 1. These devices are only available in OTP versions.          2. Fast start-up: < 5ms (fSYS=455kHz, the RESB is connected to VDD)          3. Low power consumption: (IDD<200mA, when fSYS=455kHz, VDD=+5V)

答 9: 唉？？我看现在好多都用HT的！
在这里问一下，大家觉得HT好用还是EMC好用，哪个更有优势？
因为我很少发现在论坛上有人推荐EMC的！ 答 10: ht有价格优势 答 11: EMC的IC也可以HT和EMC比较起来,EMC的质量可能比较差点.
