Advance Information
C868
• C800 core :
–Fully compatible to standard 8051 microcontroller
–Superset of the 8051 architecture with 8 datapointers
• 40 MHz internal CPU clock
–external clock of 6.67 - 10.67 MHz at 50% duty cycle
–300 ns instruction cycle time (@37.5 MHz CPU clock)
• 8 Kbyte on-chip Program ROM for C868-1R and 8 KByte on-chip Program RAM for
C868-1S
• In-system programming support for programming the XRAM(C868-1R) or XRAM/
Program RAM(C868-1S)
–This feature is realized through 4KB Boot ROM
• 256 byte on-chip RAM
