The Pace-Setting Performance and Features of the 56F8300 Hybrid Controllers
Figure 1-13. ADC Functional Block Diagram
The ADC has a sophisticated set of operating modes and capabilities. Each 56F8300 devices has either
one or two of these modules. Here are some of the features and benefits of Motorola’s ADC module:
• 12-bit resolution
• Two ADC conversion units per module, with up to eight analog inputs
• Sampling rate up to 1.66 million samples per second
• Single conversion in 1.2µs
• Eight conversions in 5.3µs by using simultaneous sampling mode
• Can be synchronized with Pulse Width Modulators (PWM)
• Simultaneous or sequential sampling
• Eight-word result buffer
• Sample correction via programmable offset
• Current injection protection circuitry
• Software self-calibration capability
— Removes gain and offset errors
• Interrupt generating capabilities
— End-of-Scan, zero crossing, high/low limit check
• Two outputs formats available
— Two’s complement
— Unsigned
• Power-Down and Power-Saving Modes
