ADMCF328BR-REEL

Digital Signal Processor Dsp Overview

The ADMCF328BR-REEL is a 28-lead Flash Memory DSP Motor Controller with Current Sense, manufactured by Analog Devices Inc. It integrates a 20 MIPS fixed-point DSP core based on the ADSP-2171 architecture, featuring single-cycle instruction execution at 50 ns. The device includes 4K x 24-bit program flash memory, 512 x 24-bit program RAM, and 512 x 16-bit data RAM. Key peripherals comprise a three-phase 16-bit PWM generator, an integrated ADC subsystem with five analog inputs plus one dedicated ISENSE input, and a 9-pin digital I/O port. It operates within a supply voltage range of 4.5 V to 5.5 V and supports temperatures from -40°C to +85°C.

Digital Signal Processor Dsp Feature Summary

• 20 MIPS Fixed-Point DSP Core (ADSP-2171) with Single Cycle Instruction Execution
• Integrated 4K x 24-bit Program Flash Memory with Security Lock Bit
• Three-Phase 16-Bit Center-Based PWM Generator with Programmable Dead Time
• ADC Subsystem with Five Analog Inputs and Dedicated ISENSE Amplifier

Digital Signal Processor Dsp Applications

• Permanent Magnet Synchronous Motors (PMSM)
• Brushless DC Motors (BDCM)
• Washing Machines and Refrigerator Compressors
• Industrial Variable Speed Drives

Digital Signal Processor Dsp Procurement Notes

Verify the package option matches the required form factor; the BR suffix indicates a 28-Lead Wide Body SOIC package. Confirm that the REEL7 designation corresponds to the specific tape and reel quantity required for automated assembly processes. Ensure compatibility with the development tools for flash programming utilities.

Digital Signal Processor Dsp Selection Notes

Select this component when code compatibility with the ADSP-21xx family is required alongside integrated motor control peripherals. The ADMCF328 is suitable for applications needing on-chip non-volatile storage for user programs without external memory interfaces. Consider the pin multiplexing capabilities if digital I/O or auxiliary PWM functions are needed alongside serial communication.

Digital Signal Processor Dsp Part Context

The ADMCF328 belongs to the ADMCxxx series of DSP-based motor controllers from Analog Devices. It combines the processing power of the ADSP-2171 with specialized hardware for motor drive applications, reducing system complexity by integrating power stage control signals and current sensing directly onto the microcontroller die.

Digital Signal Processor Dsp Replacement Considerations

The ADMCF328BN is available in a PDIP package as a physical alternative. For functional upgrades, newer members of the ADSP-21xx family may offer enhanced performance but require architectural review.
