DSPIC33EV256GM004-I/ML

Microcontrollers Overview

The DSPIC33EV256GM004-I/ML is a 16-bit Digital Signal Controller from the dsPIC33EV family, manufactured by Microchip Technology. It features a 16-bit dsPIC33E CPU core with 256 KB of Flash program memory and 16 KB of SRAM. The device operates on a 4.5V to 5.5V supply voltage and supports clock frequencies up to 70 MIPS at temperatures ranging from -40°C to +85°C. It is housed in a 44-pin QFN package.

Microcontrollers Feature Summary

• Includes Error Correction Code (ECC) for Flash memory and an intermediate security boot segment.
• Features two alternate register sets designed to facilitate fast context switching.
• Integrates advanced analog peripherals including op amps, comparators, and a Charge Time Measurement Unit (CTMU).
• Supports automotive-grade reliability through AEC-Q100 qualification.

Microcontrollers Applications

• Automotive sensor systems requiring SENT protocol support.
• Industrial motor control applications utilizing PWM and ADC modules.
• Power management systems involving DC/DC or AC/DC conversion.
• General-purpose digital signal processing tasks within embedded controllers.

Microcontrollers Procurement Notes

Verify the specific suffix 'I/ML' against official datasheets to confirm the industrial temperature range (-40°C to +85°C) and the 44-pin QFN package type. Ensure that the required peripheral configuration matches the GM004 variant specifications before finalizing procurement orders.

Microcontrollers Selection Notes

Select this component when a 16-bit architecture with high-voltage tolerance (5V) is required alongside robust safety features like ECC flash. It is suitable for designs needing flexible I/O remapping via PPS and integrated analog capabilities without external components.

Microcontrollers Part Context

This part belongs to the dsPIC33EVXXXGM00X/10X family, which focuses on 16-bit performance with enhanced analog features. The GM004 designation indicates the inclusion of standard communication interfaces such as UART, SPI, and I2C, distinguishing it from GM10X variants that add CAN bus capabilities.

Microcontrollers Replacement Considerations

Consult the manufacturer's documentation for direct pin-compatible alternatives within the same series. Verify that any substitute maintains the 44-pin QFN footprint and the necessary 5V operating voltage requirements.
