C508
Introduction
Listed below is a summary of the main features of the C508 microcontroller:
• Fully compatible to standard 8051 microcontroller
• Superset of the 8051 architecture with eight datapointers
• 10 to 20 MHz internal CPU clock (using built-in PLL with a factor of 2)
– external clock of 5 - 10 MHz at 50% duty cycle
– 300 ns instruction cycle time at 20 MHz CPU clock
• 32 Kbytes on-chip ROM/OTP (with optional ROM protection)
• 256 bytes on-chip RAM
• 1024 bytes on-chip XRAM
• Six 8-bit ports,
– Ports 1 and 2 with enhanced current sinking capabilities of 10 mA per pin
(total max. of 100 mA)
– Port 4 with pure analog/digital input channels
• Three 16-bit timers/counters
– Timer 0 /1 (C501 compatible)
– Timer 2 with four channels for 16-bit capture/compare operation
• Capture/Compare Unit (CCU) for PWM (Pulse Width Modulation) signal generation
– 3-channel, 16-bit capture/compare unit
– 1-channel, 10-bit compare unit
• Full-duplex serial interface with programmable baudrate generator (USART)
• 8-channel 10-bit A/D Converter
• 19 interrupt vectors with four priority levels
• On-chip emulation support logic (Enhanced Hooks Technology)
• Programmable 15-bit Watchdog Timer
• Oscillator Watchdog
• Fast Power On Reset
• Power Saving Modes
– Slow-down mode
– Idle mode (can be combined with slow-down mode)
– Software power-down mode with wake up capability through P3.2/INT0 or P5.7/
INT7
• ALE switch-off capability for reduction in RFI emission
• P-MQFP-64-1, P-SDIP-64-2 packages
• Temperature ranges:
SAB-C508 T_A = 0 to 70 °C
SAF-C508 T_A = -40 to 85 °C
