最近找到一些有趣的資料,大致歸類一些數據如下,Sample price 約為 3.26 - 4.38 US$,單純的Transceiver只要2$左右。
- 9mm x 9mm x 1mm 71-pin LGA
 - 40 MHz low power HCS08 CPU
 - 16kB - 60KB of flash memory
 - 1KB - 4KB of RAM
 - supports star, mesh and cluster tree topologies
 - 16 MHz crystal clock
 - 8-bit port keyboard interrupt (KBI)
 - 8-channel 8-10-bit ADC @@ 14.0 μsec, 10-bit single conversion time at a conversion frequency of 2 MHz
 - Inter-integrated circuit (IIC) interface. 100 kbps with maximum bus loading
 - Up to 32 MCU GPIO with programmable pullups
 - transceiver supports 250 kbps O-QPSK data in 5.0 MHz and Direct Sequence Spread Spectrum (DSSS) coding
 
hmm應該是看錯顆,這顆看起來是Transciver,靠果然是黑店,CC243x 系列的SOC通通超過5$,甚至有10$以上的,功能上有多一些拉,不過有那麼值錢嗎?
- 128-bit AES
 - CSMA/CA hardware support
 - Digital RSSI / LQI support 這不知是啥。
 - Powerful DMA functionality ...還有DMA勒。
 
- Requires Z-Stack download and purchase of full license by Aug 4 2006?
 
- How long of distance?
 - ZigBee 的 Routing 機制及本身發送衝突問題?
 - 應用? 嘿嘿各憑本事了 Secret!。
