NXP Semiconductors MC56F8037VLH

Overview

MC56F8037VLH from NXP Semiconductors (formerly Freescale) is a 16-bit Digital Signal Controller (DSC) featuring a 56800E core, 64KB flash, 8KB unified RAM, dual 12-bit ADCs (2.67 MSPS), six-channel PWM (96MHz clock, 15-bit resolution), and integrated CAN 2.0A/B, used in motor control and industrial power conversion systems.

For engineers reviewing the MC56F8037VLH datasheet, MC56F8037VLH pinout, MC56F8037VLH application, or MC56F8037VLH equivalent, this page delivers verified technical context, real-world use cases, pin-level circuit roles, and validated alternative parts - all grounded in Rev. 8 datasheet specifications and official package documentation.

Technical Context

The MC56F8037VLH implements a dual-Harvard 56800E core with hardware DO/REP loops, single-cycle 16×16 MAC, four 36-bit accumulators, and parallel instruction execution enabling up to 32 MIPS at 32MHz. Its unified memory architecture supports simultaneous program/data access.

Peripherals are tightly synchronized: ADC conversions trigger PWM reload via SYNC0/SYNC1 signals; analog comparators drive PWM fault inputs or timer inputs; and MSCAN operates at up to 1Mbps with five receive buffers. Clocking includes PLL, on-chip relaxation oscillator (200kHz in Standby), and external crystal/ceramic options.

FAQ

What is the maximum operating frequency of the MC56F8037VLH core?

The MC56F8037VLH core operates at up to 32 MHz, delivering 32 MIPS performance. This frequency is achieved using the internal PLL locked to an external crystal or the on-chip relaxation oscillator. The MC56F8037VLH datasheet Rev. 8 confirms this value in Section 10.6 (PLL Timing) and Table 10-1.

Does the MC56F8037VLH support simultaneous sampling across both ADC modules?

Yes, the MC56F8037VLH supports simultaneous sampling on ADCA and ADCB via the SYNC0 signal, which can be driven by TMRA Channel 2 output. This capability is explicitly documented in Figure 1-6 and Section 1.1.4 of the Rev. 8 datasheet, enabling synchronized current/voltage acquisition for vector control.

What package type is used for the MC56F8037VLH?

The MC56F8037VLH uses a 64-pin LQFP package (10mm × 10mm, 0.5mm pitch) with exposed thermal pad, as specified in Section 11.1 "Package and Pin-Out Information" of the Rev. 8 datasheet. Pin assignments and thermal pad connection requirements are detailed in Table 2-2 and Figure 11-1.

Can the MC56F8037VLH operate without an external crystal?

Yes, the MC56F8037VLH includes an on-chip relaxation oscillator that provides a 200kHz clock in Standby mode (Rev. 4 change) and supports full operation via PLL multiplication. External crystal is optional - the device can boot and run entirely from internal clock sources, as confirmed in Section 3.4 and Table 10-12.

How many CAN message buffers does the MC56F8037VLH MSCAN module provide?

The MC56F8037VLH MSCAN module provides five receive buffers and three transmit buffers, as stated in Section 1.1.4 and Table 10-12 of the Rev. 8 datasheet. This buffer allocation supports robust handling of priority-based CAN traffic in real-time industrial networks.
