呵呵!不选器件直接编译,若只是外接27C521可以接很多就看你的外面电路怎么给个选通地址就可以了,
或者采用上面有大侠说的可以用ADI的
8051 based controller with High-Speed Core,
8-channel true 12-bit ADC,
Dual 16-bit DAC's, WDT, SPI, UART,
On-chip DMA controller, 32 I/O lines,
3 Timers/Counters, WDT, SPI, UART, Dual Data Pointers,
Timer Interval Counter,
11 Interrupt Sources/2 Priority Levels,
62K Flash EEPROM Program Memory,
2K Data Flash EEPROM, 2304 Bytes On-chip RAM,
RAM banking up to 16M Bytes external address space,
UART,SPI, I2C, brown out detect.
*** IMPORTANT ***
The PK51 Professional Developer's Kit is required
if you wish to create programs that access the
16M Byte external address space. |
