NXP Semiconductors DSP56F807VF80

Overview

DSP56F807VF80 from Freescale Semiconductor is a 16-bit Digital Signal Controller (DSC) integrating DSP and MCU functionality on a single chip, featuring a 56800 core running at up to 80 MHz (40 MIPS), 60 KB program Flash, dual 6-channel PWM modules with fault protection, four 12-bit ADCs, two quadrature decoders, CAN 2.0B interface, and JTAG/OnCE debug support - deployed in motor control systems for ACIM, BLDC, and stepper drives.

For engineers reviewing the DSP56F807VF80 datasheet, DSP56F807VF80 pinout, DSP56F807VF80 application, or DSP56F807VF80 equivalent, key selection considerations include PWM dead-time programmability, synchronized ADC-PWM timing, CAN 2.0B compliance, external memory expansion capability (64 KB each for program/data), and 160-pin LQFP package compatibility with industrial motion control PCB layouts.

Technical Context

The DSP56F807VF80 implements a dual-Harvard architecture with three parallel execution units enabling up to six operations per instruction cycle. Its 16×16-bit MAC executes in one cycle with two 36-bit accumulators, hardware DO/REP loops, and 14 addressing modes optimized for C-compiled control code.

Peripheral integration includes two independent PWM modules (12 total outputs), each supporting edge- and center-aligned modes, programmable dead time, current-sense input synchronization, and fault-input-driven output disable. ADCs are quad 4-channel, 12-bit converters with simultaneous sampling and PWM-triggered conversion start.

FAQ

What is the maximum operating frequency and instruction throughput of the DSP56F807VF80?

The DSP56F807VF80 operates at a maximum core frequency of 80 MHz, delivering up to 40 million instructions per second (MIPS). This performance level is achieved through its dual-Harvard architecture and parallel execution units, enabling real-time execution of complex motor control algorithms such as field-oriented control and sensorless commutation without external co-processors. The DSP56F807VF80 sustains this throughput across its full temperature range (-40°C to +105°C) with proper power supply decoupling and thermal management.

Does the DSP56F807VF80 support CAN 2.0B, and what are the physical interface requirements?

Yes, the DSP56F807VF80 integrates a fully compliant CAN 2.0B module with dedicated MSCAN_TX and MSCAN_RX pins. The TX pin is open-drain and requires an external pull-up resistor (typically 4.7 kΩ to 3.3V), while the RX pin includes an internal pull-up. It supports both standard (11-bit) and extended (29-bit) identifier frames and operates at bit rates up to 1 Mbps. No transceiver is integrated - an external CAN transceiver (e.g., TJA1040) must be used to interface with the physical bus.

How many PWM outputs does the DSP56F807VF80 provide, and what fault protection mechanisms are included?

The DSP56F807VF80 provides 12 PWM outputs across two independent modules (PWMA0–5 and PWMB0–5), each supporting complementary pair operation with programmable dead time. Each module includes four dedicated fault inputs (FAULTA0–3 and FAULTB0–3) that disable specific outputs within one clock cycle upon assertion. Additional protection includes current-sense inputs (ISA0–2 and ISB0–2) for real-time pulse-width correction and "smoke-inhibit" write-once register locking for critical PWM parameters.

What ADC capabilities does the DSP56F807VF80 offer, and how are they synchronized with PWM?

The DSP56F807VF80 integrates four 12-bit ADCs (ADCA/ADCB ×2), each with four input channels and support for simultaneous sampling. ADC conversion triggers can be synchronized to PWM events - including center-aligned or edge-aligned points - ensuring deterministic sampling of motor phase currents at optimal moments. This synchronization is configured via hardware registers and requires no CPU intervention, enabling jitter-free current measurement critical for high-performance motor control.

Is the DSP56F807VF80 pin-compatible with other members of the 56F80x family, and what package options exist?

Yes, the DSP56F807VF80 is pin-compatible with the DSP56F805VF80 and DSP56F803VF80 in the 160-pin LQFP (VF80) package. All share identical pin assignments for power, ground, PWM, ADC, CAN, SCI, SPI, quadrature decoder, and JTAG signals. The VF80 suffix explicitly denotes the 160-pin LQFP variant; no BGA or smaller LQFP options exist for this specific part number. Pin compatibility enables direct substitution in existing designs when memory or feature requirements change.
