NXP Semiconductors MC56F80648VLH

Overview

MC56F80648VLH from NXP Semiconductors is a 32-bit digital signal controller (DSC) based on the 56800EF core, operating at up to 100 MHz with 64 KB flash and 8 KB RAM. It integrates dual 12-bit ADCs with x1/x2/x4 programmable gain amplifiers, three analog comparators with integrated 8-bit DAC references, and an eFlexPWM module supporting up to 8 channels with 312 ps NanoEdge resolution-targeted for industrial motor control and solar inverter systems.

For engineers reviewing the MC56F80648VLH datasheet, MC56F80648VLH pinout, MC56F80648VLH application, or MC56F80648VLH equivalent, key selection criteria include its V-grade temperature range (–40°C to +105°C), 64-pin LQFP package, dual QSCI with LIN slave support, LPI2C with full PMBus compliance, and eFPU/CORDIC acceleration for real-time control math.

Technical Context

The MC56F80648VLH implements the 56800EF core with unified DSP/MCU architecture, featuring single-cycle 32×32→64-bit MAC, eFPU compliant with IEEE 754-2008, and CORDIC engine for trigonometric/hyperbolic functions in Q5.27 format. Its memory map supports flexible program/data space allocation across 64 KB flash and 8 KB RAM.

Peripherals are tightly coupled via the Inter-Module Crossbar and Event Generator: ADC conversions synchronize to PWM edges; comparator outputs trigger eFlexPWM fault shutdown; and PIT timers feed quadrature decoder inputs. Clocking uses configurable sources-including 8/2 MHz IRC, 200 kHz low-power oscillator, and external 4–16 MHz crystal-with PLL output optimized from 200–550 MHz.

Key Specifications

Pinout & Package

MC56F80648VLH is housed in a 64-pin LQFP package (10 × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are multiplexed via GPIOx_PER and SIM GPSx registers; all pins default to GPIO input after reset except JTAG and RESET_B.

FAQ

What is the maximum operating frequency of the MC56F80648VLH core?

The MC56F80648VLH features a 32-bit 56800EF core rated for up to 100 MHz operation, delivering 100 MIPS performance. This frequency is achievable across the full V-grade temperature range (–40°C to +105°C) when powered within the specified 2.7–3.6 V supply range and using appropriate decoupling and thermal design per the MC56F80XXX datasheet.

Does the MC56F80648VLH support LIN communication?

Yes, the MC56F80648VLH includes two queued serial communication interface (QSCI) modules, each supporting LIN slave functionality per LIN 2.2A specification. The hardware handles frame formatting, checksum calculation, and wakeup detection-freeing the CPU from protocol overhead while maintaining strict timing compliance for automotive body electronics integration.

How many analog-to-digital converter channels does the MC56F80648VLH have?

The MC56F80648VLH integrates two independent 12-bit cyclic ADCs (ADCA and ADCB), each supporting up to 14 external analog inputs. Both ADCs feature programmable x1/x2/x4 gain amplifiers, hardware-triggered sampling synchronized to PWM events, and on-chip temperature sensing-enabling simultaneous acquisition of motor phase currents and DC-link voltage in inverter designs.

What package type is used for the MC56F80648VLH?

The MC56F80648VLH is supplied in a 64-pin LQFP package (10 × 10 mm body, 0.5 mm lead pitch) with exposed thermal pad. This package provides 54 usable GPIOs and full access to all peripherals-including dual QSCI, QSPI, LPI2C, eFlexPWM, and ADC channels-as confirmed in the MC56F80XXX pinout diagrams and ordering information.

Is the MC56F80648VLH pin-compatible with other MC56F80xxx devices?

No, the MC56F80648VLH is not universally pin-compatible across the MC56F80xxx family. While it shares the 64-pin LQFP footprint with MC56F80748VLH, pin functions differ for peripherals like eQDC and second QSCI. Engineers must verify signal assignments per device-specific pinout tables-especially for ADC inputs, PWM outputs, and communication interfaces-before PCB layout reuse.
