Freescale 的ＭＣ９Ｓ１２Ｄ６４怎么樣? |
| 作者：wenming 欄目：單片機(jī) |
呵呵，用了兩年的AVR.最近開始在下面的兩個項(xiàng)目中使用FREESCALE 的ＭＣ９Ｓ１２Ｄ６４． 主要是想看看，那個號稱世界上銷售量第一的廠商做的單片機(jī)到底怎么樣． 大家給點(diǎn)意見，以下是Ｄ６４的基本性能，價格大約在７０元，也可以使用ＧＣＣ開發(fā)． 呵呵，順便說一下，我們的產(chǎn)品對成本不敏感．礦井下的東西，穩(wěn)定性是第一的！ The MC9S12D64 microcontroller unit (MCU) is a 16-bit DEVICE composed of STANDARD on-chip peripherals including a 16-bit CENTRAL processing unit (HCS12 CPU), 64K bytes of FLASH EEPROM, 4K bytes of RAM, 1K bytes of EEPROM, two asynchronous serial communications interfaces (SCI), one serial peripheral interfaces (SPI), an 8-channel IC/OC enhanced capture timer, two 8-channel, 10-bit analog-to-DIGITAL converters (ADC), an 8-channel pulse-width modulator (PWM), a DIGITAL Byte Data LINK Controller (BDLC), 29 discrete DIGITAL I/O channels (PORT A, PORT B, PORT K and PORT E), 20 discrete DIGITAL I/O lines with interrupt and wakeup capability, a CAN 2.0 A, B SOFTWARE compatible MODULES (MSCAN12), and an Inter-IC Bus. The MC9S12D64 has full 16-bit data paths throughout. However, the external bus can operate in an 8-bit narrow mode so SINGLE 8-bit wide MEMORY can be interfaced for lower cost systems. The inclusion of a PLL CIRCUIT allows POWER consumption and performance to be adjusted to suit operational requirements. |

D64 我用過D64,它的抗干擾能力很強(qiáng),芯片的各引腳間的獨(dú)立性很好(我是指如果有單個引腳串入高壓,它只燒毀該引腳而不會影響其它引腳的功能),它的主頻為25M.適應(yīng)溫度范圍為-40---105,適合工業(yè)現(xiàn)場應(yīng)用,但國內(nèi)做的人不多.遇到問題只能找MOTOROLA 的技術(shù)支持 |
