NXP Semiconductors MC56F8247VLH

Overview

MC56F8247VLH from Freescale Semiconductor is a 60 MHz digital signal controller (DSC) based on the 56800E core, integrating DSP performance with microcontroller functionality in a single chip. It features 48 KB flash, 8 KB unified RAM, dual 12-bit ADCs (2×8-channel), eFlexPWM with 6 high-resolution (520 ps) NanoEdge channels, and supports motor control, solar inverters, and battery management systems.

For engineers reviewing the MC56F8247VLH datasheet, MC56F8247VLH pinout, MC56F8247VLH application, or MC56F8247VLH equivalent, key selection considerations include its 44-pin LQFP package, 3.0–3.6 V supply, –40 °C to +105 °C temperature range, and integrated peripherals including MSCAN, QSCI with LIN slave, and crossbar-switched analog/digital I/O routing.

Technical Context

The MC56F8247VLH implements a modified Harvard architecture with three parallel execution units enabling up to six operations per instruction cycle. Its 56800E core delivers 60 MIPS at 60 MHz and supports efficient C compilation via hardware DO/REP loops, 32-bit ALU, and four 36-bit accumulators.

Peripherals are interconnected via a programmable inter-module crossbar (XBAR), allowing dynamic routing of ADC triggers, PWM fault inputs, timer signals, and comparator outputs to GPIOs or internal modules - enabling flexible real-time control without fixed signal paths.

Key Specifications

FAQ

What is the maximum operating frequency of the MC56F8247VLH core?

The MC56F8247VLH core operates at a maximum frequency of 60 MHz, delivering up to 60 million instructions per second (MIPS). Its high-speed peripheral clock runs at 120 MHz, enabling fast operation of timers, QSCI, and QSPI modules. This frequency is sustained across the full industrial temperature range (–40 °C to +105 °C) under 3.0–3.6 V supply conditions, as specified in the MC56F825x/MC56F824x Technical Data Sheet Rev. 4.

Does the MC56F8247VLH support CAN communication?

No, the MC56F8247VLH does not include the MSCAN module. CAN capability is present only in the MC56F825x variants (e.g., MC56F8255VLH) and select MC56F824x derivatives like MC56F8246VLH. The MC56F8247VLH retains all other peripherals - including dual ADCs, eFlexPWM, QSCI with LIN slave, I²C, QSPI, and crossbar - but omits the CAN controller to optimize cost and die size for non-CAN applications.

How many analog input channels does the MC56F8247VLH support?

The MC56F8247VLH supports 16 total analog input channels: eight for ADC A (ANA0–ANA7) and eight for ADC B (ANB0–ANB7), accessible via GPIO pins A0–A7 and B0–B7. Both ADCs are 12-bit, feature programmable x1/x2/x4 gain, and achieve minimum conversion times of 600 ns. Input current-injection protection and dedicated reference pins (VREFHA/VREFLA/VREFHB/VREFLB) are included for robust signal acquisition.

What package type and dimensions does the MC56F8247VLH use?

The MC56F8247VLH uses a 44-pin LQFP package with 10 mm × 10 mm body size and 0.8 mm lead pitch. This package is mechanically defined in Freescale's MC56F825x Technical Data Sheet Rev. 4, Section 10.1. It includes five power pins (VDD, VDDA, VCAP, VSS, VSSA), one dedicated reset pin, and 35 GPIOs - 16 of which double as analog inputs, and 8 as eFlexPWM outputs - all compatible with 5 V tolerant logic levels.

Is the MC56F8247VLH pin-compatible with other members of the MC56F824x family?

Yes, the MC56F8247VLH is pin-compatible with other 44-pin LQFP variants in the MC56F824x family, including MC56F8245VLH and MC56F8246VLH. All share identical pin numbering, power/ground allocation, and peripheral pin mappings (e.g., ADC inputs on GPIOA/B, eFlexPWM on GPIOE, QSCI on GPIOC/F). Differences are internal - flash/RAM size, PWM input capture, and MSCAN presence - requiring only firmware and configuration updates, not PCB redesign.
