Overview

The MC56F84xx is the market’s fastest digital signal-processing microcontroller, offering exceptional precision, sensing and control for the most efficient digital power conversion and advanced motor control applications. The MC56F84xx includes advanced high-speed and high-accuracy peripherals such as a high-resolution pulsewidth modulation (PMW) with 312 pico-second resolution, dual high-speed 12-bit analog-to-digital controllers (ADCs) with built-in PGA sampling up to 3.3 mega samples per second (MsPs) and one high-precision 16-bit ADC. Faster application-specific control loops are driven via a high-speed 32-bit digital signal processing (DsP) core with single-cycle math computation, fractional arithmetic support and parallel moves.

Features and Benefits

• High-resolution PWM with 312 pico-second resolution enables higher switching frequencies, reducing cost and increasing efficiency
• 2x 12-bit high-speed ADCs with up to 3.3 MsPs resolution improves system accuracy by reducing jitter on input values
• 100 MHz/100 MIPs 32-bit core provides math capabilities needed for advanced power efficiency and motor control applications
• 64 KB to 288 KB flash memory flexibility provides scalability needed for key digital power and motor control applications
• single-cycle math computations, fractional arithmetic support and parallel moves improves performance, driving tighter and faster control loops
• Direct memory access (DMA) controller reduces core interruption, increasing performance
• Four analog comparators with integrated 6-bit DACs speed system event identification and emergency shutdown of the PWM outputs
• 5V-tolerant I/O provides design flexibility and system cost reduction
• Memory protection capability increases system safety by restricting user code from accessing key memory locations and peripherals reserved for supervisor access
• Freescale’s FlexMemory EEPROM provides scratch pad for calibration and shutdown values
• Market-focused software components, reference designs and development tools provide application expertise in the form of run-time software, schematics and other key time to market needs
