C868
Introduction
1.1
Summary of Basic Features
Listed below is a summary of the main features of the C868:
• C800 core :
–Fully compatible to standard 8051 microcontroller
–Superset of the 8051 architecture with 8 datapointers
• 6.25 - 40 MHz internal system clock (built-in PLL with software configurable divider)
–external clock of 6.67 - 10.67 MHz
–300ns instruction cycle time (@40 MHz system 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
• 256 byte on-chip XRAM
• One 8-bit and one 5 bits general purpose push-pull I/O ports
– Enhanced sink current of 10 mA on Port 1/3 (total sink current of 46 mA @ 100^oC)
• Three 16-bit timers/counters
–Timer 0 / 1
–Timer/counter 2 (up/down counter feature)
–Timer 1 or 2 can be used for serial baudrate generator
• Capture/compare unit (CCU6) for PWM signal generation
–3-channel, 16-bit capture/compare unit
–1-channel, 16-bit compare unit
• Full duplex serial interface (UART)
• 5 channel 8-bit A/D Converter
• 13 interrupt vectors with 2 priority levels
• Programmable 16-bit Watchdog Timer
• Brown out detection
• Power Saving Modes
–Slow-down mode
–Idle mode (can be combined with slow-down mode)
–Power-down mode with wake up capability through INT0 or RxD pins.
• Individual power-down control for timer/counter 2, capture/compare unit and A/D
converter.
• P-DSO-28-1, P-TSSOP-38-1 packages
• Temperature ranges:
SAB-C868-1RR,SAB-C868-1SR,SAB-C868-1RG,SAB-C868-1SG T_A = 0 to 70 ^oC
SAF-C868-1RR,SAF-C868-1SR,SAF-C868-1RG,SAF-C868-1SG T_A = – 40 to 85 ^oC
