Product details
Overview
MC56F8355VFGE from NXP (formerly Freescale) is a 16-bit digital signal controller (DSC) combining DSP and MCU functionality in a single C-efficient 56800E core, delivering up to 60 MIPS at 60 MHz, with 256 KB Program Flash, 4 KB Program RAM, 8 KB Data Flash, and dual 6-channel PWM modules for motor control. It integrates FlexCAN 2.0B, four 12-bit ADCs, two quadrature decoders, and temperature sensing - deployed in industrial motor drives and automotive engine management systems.
For engineers reviewing the MC56F8355VFGE datasheet, MC56F8355VFGE pinout, MC56F8355VFGE application, or MC56F8355VFGE equivalent, key selection criteria include its dual PWM fault-tolerant architecture with dead-time insertion, synchronized ADC-PWM timing via Quad Timer C, 128-pin LQFP package with 49 GPIOs, and automotive-grade operating temperature range (–40°C to 125°C).
Technical Context
The MC56F8355VFGE implements a Harvard-architecture 56800E core with three parallel execution units, enabling up to six operations per instruction cycle. Its dual PWM modules support both edge-aligned and center-aligned modes with programmable dead time, cycle-by-cycle current limiting, and complementary output pairs - each module configurable for six independent or three complementary PWM outputs.
Peripheral synchronization is hardware-assisted: Quad Timer C channels 2 and 3 generate SYNC signals to trigger ADC conversions, while PWM load interrupts can feed into Timer C for controllable delay before ADC start. The FlexCAN module complies fully with ISO 11898-1 (CAN 2.0B), supporting 1 Mbit/s operation and message objects with dedicated receive/transmit buffers.

FAQ
What is the maximum operating frequency of the MC56F8355VFGE?
The MC56F8355VFGE operates at a maximum core frequency of 60 MHz, delivering up to 60 MIPS performance. This frequency is achieved using the on-chip PLL with an external crystal up to 8.4 MHz. The MC56F8355VFGE datasheet specifies guaranteed operation across the full industrial temperature range (–40°C to +125°C) at this speed, with appropriate decoupling and thermal design.
Does the MC56F8355VFGE support CAN FD or only classical CAN?
The MC56F8355VFGE integrates a FlexCAN module compliant with CAN 2.0B specification only - it does not support CAN FD data rates or extended frame formats. It operates at up to 1 Mbit/s with standard 11-bit identifiers and supports message objects, acceptance filtering, and automatic retransmission. For CAN FD, designers must consider newer NXP families such as S32K1 or MPC57xx.
How many independent PWM outputs does the MC56F8355VFGE provide?
The MC56F8355VFGE provides twelve independent PWM outputs: six from PWMA and six from PWMB. Each module supports complementary pair generation with programmable dead time, or six independent edge-aligned/center-aligned channels. The MC56F8355VFGE's dual PWM architecture enables full-bridge, three-phase, or multi-motor control without external PWM generators.
Is the MC56F8355VFGE pin-compatible with the MC56F8367VFGE?
No, the MC56F8355VFGE is not pin-compatible with the MC56F8367VFGE. Although both use 128-pin LQFP packages, signal assignments differ significantly - particularly for Ethernet, USB, and additional memory interfaces present in the MC56F8367VFGE. Migration requires PCB layout revision and firmware adaptation due to peripheral register map changes and enhanced clock tree.
What ADC resolution and sampling rate does the MC56F8355VFGE support?
The MC56F8355VFGE features four 12-bit successive-approximation ADCs with hardware-triggered sampling. Maximum conversion rate is 1.25 MSPS per ADC (800 ns conversion time), and simultaneous sampling across multiple ADCs is supported. The MC56F8355VFGE includes calibration vectors in boot flash to correct gain/offset errors, achieving ±1 LSB INL and ±0.5 LSB DNL over temperature.
