Product details
Overview
MC56F83766MLK 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 128 KB flash with ECC-targeting high-precision motor control in BLDC/PMSM inverters.
For engineers reviewing the MC56F83766MLK datasheet, MC56F83766MLK pinout, MC56F83766MLK application, or MC56F83766MLK equivalent, key selection criteria include its 64-pin LQFP package, -40°C to 125°C extended temperature grade (M), dual ADC programmable gain (x1/x2/x4), and hardware CRC generator for functional safety compliance.
Technical Context
The MC56F83766MLK implements a unified 32-bit 56800EX DSP/MCU architecture with three address buses and four data buses, enabling concurrent instruction fetch and dual data access per cycle. Its eFlexPWM subsystem supports 2×8 PWM outputs with independent deadtime, fractional delay, and NanoEdge edge placement-critical for field-oriented control in industrial drives.
Analog subsystem integration includes two synchronized 12-bit cyclic ADCs with 25 MHz max clock, on-chip temperature sensor, four comparators with 8-bit DAC references, and two 12-bit DACs supporting auto-generated waveforms-enabling closed-loop current/voltage sensing without external signal conditioning.
