It integrates 64 KB flash, 8 KB dual-port RAM, two 12-bit ADCs (8-channel each), eight high-resolution eFlexPWM outputs, and supports motor control (BLDC/PMSM), switched-mode power supplies, and industrial automation with AEC-Q100 qualification for automotive-grade reliability.

For engineers reviewing the MC56F82748VLHR datasheet, MC56F82748VLHR pinout, MC56F82748VLHR application, or MC56F82748VLHR equivalent, key selection criteria include its 64-pin LQFP package, -40°C to 105°C V-temp grade, 3.0–3.6 V single supply, 5 V–tolerant I/O (excluding RESETB), and integrated MSCAN, QSCI, QSPI, and I²C interfaces for real-time embedded control systems.

Technical Context

The MC56F82748VLHR implements a unified 32-bit 56800EX DSP/MCU architecture with three address buses and four data buses, enabling concurrent instruction fetches and dual data accesses per cycle. Its eFlexPWM module supports eight independent or complementary PWM outputs with NanoEdge timing resolution, deadtime insertion, and fault protection across up to eight inputs.

Analog subsystem includes two synchronized 12-bit cyclic ADCs with programmable x1/x2/x4 gain amplifiers, 10 MHz max clock, and hardware-triggered conversion via crossbar; plus four analog comparators with 6-bit DAC references and two 12-bit DACs supporting automatic waveform generation (square/triangle/sawtooth) for slope compensation.

FAQ

What is the maximum operating frequency of the MC56F82748VLHR core?

The MC56F82748VLHR core operates at up to 100 MHz in fast mode, delivering 100 MIPS performance. This frequency is achieved using the on-chip PLL with an input reference clock of 8–16 MHz. The device also supports 50 MHz operation in normal mode. All timing specifications in the MC56F827XXDS datasheet are validated at 100 MHz, and the MC56F82748VLHR maintains full functionality across its specified -40°C to +105°C temperature range at this speed.

Does the MC56F82748VLHR support CAN communication?

Yes, the MC56F82748VLHR includes a Modular/Scalable Controller Area Network (MSCAN) module compliant with CAN 2.0 A/B protocol, supporting standard and extended frames, bit rates up to 1 Mbit/s, and programmable message buffers with individual mask registers. This module is fully integrated into the MC56F82748VLHR's crossbar architecture, allowing hardware-synchronized triggering with ADC or PWM events - essential for time-critical automotive and industrial networked control.

What are the power supply requirements for the MC56F82748VLHR?

The MC56F82748VLHR requires a single 3.3 V supply with a tolerance of 3.0–3.6 V for both digital (VDD/VSS) and analog (VDDA/VSSA) domains. It features a dedicated VCAP pin for the internal core regulator, requiring a 2.2 µF ceramic capacitor to ground. The I/O pins are 5 V–tolerant except RESETB, which is strictly 3.3 V. Brown-out reset activates below 2.0 V, and low-voltage interrupts trigger at 2.2 V (critical) and 2.7 V (peripheral warning).

How many ADC channels does the MC56F82748VLHR support, and what is their resolution?

The MC56F82748VLHR integrates two independent 12-bit cyclic ADC modules, each with 8 external input channels (ADC0_IN0–ADC0_IN7 and ADC1_IN0–ADC1_IN7), for a total of 16 configurable analog inputs. Each ADC supports programmable gain amplifiers (x1/x2/x4), differential and single-ended acquisition, and hardware synchronization to PWM or timer events. Conversion time is 10 ADC clock cycles (minimum 100 ns period), and results are stored in dual-buffered registers accessible via DMA or CPU.

Is the MC56F82748VLHR pin-compatible with other members of the MC56F827xx family?

Yes, the MC56F82748VLHR in the 64-pin LQFP package shares identical pinout and signal mapping with all other 64-pin variants in the MC56F827xx family, including MC56F82748MLH, MC56F82738VLH, and MC56F82728VLH. This allows direct PCB reuse across different flash/RAM configurations and temperature grades. Pin compatibility is explicitly confirmed in Table 2 of the MC56F827XXDS datasheet, and all GPIO, peripheral, and power pin assignments remain consistent across these variants.
