Product details
Overview
MC56F83789AMLLA from NXP Semiconductors is a 32-bit digital signal controller (DSC) based on the 56800EX core, delivering 100 MIPS at 100 MHz. It integrates dual 12-bit ADCs (8+2 external + internal channels), two eFlexPWM modules with NanoEdge 312 ps resolution, FlexCAN with CAN-FD support, and 256 KB flash with ECC-targeting high-precision motor control in industrial inverters and PMSM drives.
For engineers reviewing the MC56F83789AMLLA datasheet, MC56F83789AMLLA pinout, MC56F83789AMLLA application, or MC56F83789AMLLA equivalent, key selection criteria include its AEC-Q100-qualified M-temp grade (-40°C to 125°C), 100-pin LQFP package, dual partition flash swap capability, and integrated USB 2.0 device controller with on-chip PHY.
Technical Context
The MC56F83789AMLLA implements a unified DSP/MCU architecture with three internal address buses and four data buses enabling concurrent instruction fetch and dual data access per cycle. Its 56800EX core supports fractional arithmetic, hardware DO/REP loops, and bit-reverse addressing for FFT acceleration-critical for real-time sensor fusion and field-oriented control.
Peripherals are tightly coupled via an inter-module crossbar and event generator, allowing deterministic synchronization between ADC conversions, PWM edge placement, and comparator triggers. The eFlexPWM modules support independent deadtime insertion, complementary pair control, and FORCE_OUT event-driven simultaneous output updates-enabling precise gate drive timing in three-phase inverter topologies.
