DSP56F801FA80E

Microcontrollers Overview

The DSP56F801FA80E is a 16-bit Digital Signal Controller from the 56F8xx family, built on the 56800 core. It operates at up to 80MHz (40 MIPS) and features 8K x 16-bit Program Flash, 2K x 16-bit Data Flash, 1K x 16-bit Program RAM, and 1K x 16-bit Data RAM. The device includes a 6-channel PWM module, two 4-channel 12-bit ADCs, SCI, SPI, and a Quad Timer. It utilizes a 48-pin LQFP package and supports a 3.0V to 3.6V supply voltage.

Microcontrollers Feature Summary

• Integrates a 16-bit 56800 core with dual Harvard architecture for parallel DSP and MCU operations.
• Includes a fault-tolerant 6-channel PWM module with dead-time insertion and cycle-by-cycle current limiting.
• Features two synchronized 12-bit Analog-to-Digital Converters with multiplexed inputs.
• Provides programmable Boot Flash for customized boot code and field upgrades via JTAG or SPI.

Microcontrollers Applications

• Motor control for ACIM, BDC, BLDC, SRM, VRM, and stepper motors
• Smart appliances and industrial power control systems
• Automotive engine management and noise suppression
• Remote utility metering and distributed power generation

Microcontrollers Procurement Notes

Verify the specific suffix 'FA80E' against official NXP documentation to confirm pinout, temperature range, and package variations. Ensure compatibility with existing board layouts regarding the 48-pin LQFP dimensions. Confirm that the 3.3V supply requirements align with system power rails. Check for any RoHS compliance updates in the latest datasheet revision.

Microcontrollers Selection Notes

Select this component when a unified DSP/MCU solution is required for motion control or power conversion. The 56800 core offers efficient C compiler support and hardware loops for compact code. Consider the integrated PWM and ADC capabilities if analog feedback and motor drive signals are needed without external components. Evaluate the 48-pin package constraints against available GPIO and peripheral routing needs.

Microcontrollers Part Context

The DSP56F801 belongs to the 56F8xx series of 16-bit Digital Signal Controllers designed by NXP (formerly Freescale). This family combines high-performance DSP processing with microcontroller peripherals. The 56F801 specifically targets cost-sensitive applications requiring moderate flash memory and robust motor control features within a compact footprint.

Microcontrollers Replacement Considerations

Consult the DSP56F801/803/805/807 User’s Manual for cross-referencing within the same family. Verify pin compatibility and memory size differences before substituting with other 56F8xx variants.
