NXP Semiconductors MC56F8006VLF

Overview

MC56F8006VLF from NXP Semiconductors (formerly Freescale) is a 16-bit digital signal controller (DSC) built on the 56800E core, delivering up to 32 MIPS at 32 MHz. It integrates 16 KB flash, 2 KB unified RAM, dual 12-bit ADCs (400 KSPS), six PWM outputs with dead-time control, two PGAs (up to 32× gain), three analog comparators, and I²C/SPI/SCI interfaces. It targets motor control (BLDC, PMSM), power supplies, and industrial sensing.

For engineers reviewing the MC56F8006VLF datasheet, MC56F8006VLF pinout, MC56F8006VLF application, or MC56F8006VLF equivalent, this page provides verified package mapping (48-pin LQFP, 7 × 7 mm²), validated peripheral timing (e.g., 96 MHz PWM clock), confirmed operating range (–40 °C to +125 °C, 1.8–3.6 V), and real-world DSC selection criteria including PGA-ADC synchronization, COP watchdog clock source options, and PDB-triggered conversion alignment.

Technical Context

The MC56F8006VLF implements a dual-Harvard 56800E core with three parallel execution units enabling up to six operations per instruction cycle. Its architecture supports hardware DO/REP loops, four 36-bit accumulators, and a single-cycle 16 × 16-bit MAC - optimized for both DSP math and real-time control flow.

Peripherals are tightly coupled via the IPBus bridge: the PDB synchronizes PGA sampling and ADC conversions to PWM edges; the dual 12-bit ADCs accept up to 24 total analog inputs (17 shielded); and the six-channel PWM module supports center-aligned operation, asymmetric edge placement, and independent top/bottom polarity control - all configurable without CPU intervention.

Key Specifications

Pinout & Package

FAQ

What is the maximum PWM frequency supported by the MC56F8006VLF?

The MC56F8006VLF PWM module operates with a maximum clock frequency of 96 MHz, enabling edge-aligned PWM signals up to 96 MHz or center-aligned signals up to 48 MHz. Resolution is configurable up to 15 bits, and dead-time insertion is independently programmable for rising and falling edges - critical for preventing shoot-through in half-bridge power stages. This capability is fully documented in Section 3.1.5 of the MC56F8006 Technical Data Sheet (Rev. 4).

Does the MC56F8006VLF support simultaneous sampling across both ADCs?

Yes, the MC56F8006VLF supports hardware-synchronized simultaneous sampling on both ADCA and ADCB modules using triggers from the PWM or PDB modules. This allows correlated current and voltage measurements essential for accurate motor phase current reconstruction or power metering calculations. The PDB can generate precisely timed start-of-conversion pulses to both ADCs within one system clock cycle, as specified in Section 3.1.5 and Table 1 of the datasheet.

What are the valid supply voltage ranges for MC56F8006VLF operation?

The MC56F8006VLF operates across a supply voltage range of 1.8 V to 3.6 V for both digital (VDD) and analog (VDDA) domains. The device enters reset below approximately 1.9 V during power-on, and the low-voltage interrupt (LVI) can be configured to trigger at either 1.81 V or 2.31 V. This range supports direct interfacing with 3.3 V and 2.5 V systems, and its –40 °C to +125 °C rating makes it suitable for under-hood automotive and industrial power electronics applications.

How many GPIO pins does the MC56F8006VLF provide, and what configuration options are available?

The MC56F8006VLF provides up to 40 general-purpose I/O pins, all multiplexed with peripheral functions. Each pin supports individual direction control (input/output), configurable pull-up devices, input hysteresis, slew rate limiting, drive strength selection (up to 20 mA sink/source), and optional low-pass filtering. Pin function selection is managed via the System Integration Module (SIM) registers, and peripheral enable/disable is controlled independently - allowing flexible resource allocation without hardware changes.

Is the MC56F8006VLF pin-compatible with other members of the 56F800x family?

No, the MC56F8006VLF is not pin-compatible with MC56F8002 or other variants in the 56F800x family. While all share the same 48-pin LQFP package outline (932-03), pin assignments differ significantly - especially for ADC inputs, PWM outputs, and comparator connections - as shown in Table 4 of the MC56F8006 Technical Data Sheet. Board designs must be verified against the specific MC56F8006VLF pinout; substitution requires layout revision.
