DSPIC33EV256GM106-I/MR

Microcontrollers Overview

The dsPIC33EV256GM106-I/MR is a 16-bit Digital Signal Controller from the dsPIC33EVXXXGM00X/10X family, manufactured by Microchip Technology. It features a 16-bit dsPIC33E CPU with two 40-bit accumulators and single-cycle MAC operations. The device includes 256 KB of Flash program memory and 16 KB of SRAM. It operates at frequencies up to 70 MIPS within a 4.5V to 5.5V supply range. Key peripherals include one CAN module, four DMA channels, six PWM outputs, and a 10/12-bit ADC with up to 36 analog inputs.

Microcontrollers Feature Summary

• Integrated CAN module with 32 buffers, 16 filters, and 3 masks for automotive communication
• Advanced analog capabilities including configurable 10-bit or 12-bit ADC and Charge Time Measurement Unit (CTMU)
• High-speed PWM generation supporting motor control applications with flexible trigger configurations
• Four-channel Direct Memory Access (DMA) with user-selectable priority arbitration

Microcontrollers Applications

• Automotive sensor interfaces using SENT protocol
• Brushless DC (BLDC) and Permanent Magnet Synchronous Motor (PMSM) control
• Industrial power conversion systems such as inverters and PFC
• Capacitive touch sensing implementations via CTMU

Microcontrollers Procurement Notes

Verify the specific suffix 'I/MR' corresponds to the industrial temperature range (-40°C to +85°C) and QFN-64 package. Confirm AEC-Q100 Grade 1 compliance requirements against your system specifications. Check for any associated errata sheets regarding silicon revisions before finalizing procurement.

Microcontrollers Selection Notes

Select this component when a 5V tolerant 16-bit DSC with integrated CAN and high-resolution analog features is required. Compare against the GM00X variant if CAN functionality is not needed to optimize cost. Ensure the 256 KB Flash capacity meets firmware storage needs compared to smaller memory options in the same family.

Microcontrollers Part Context

This device belongs to the dsPIC33EVXXXGM00X/10X family, designed for 5V operation. The '106' designation indicates the inclusion of the CAN module and specific pin count/peripheral configuration. It complements the non-CAN GM00X variants within the same architectural family, offering enhanced connectivity for automotive and industrial environments.

Microcontrollers Replacement Considerations

dsPIC33EV256GM006-I/MR lacks the CAN module but shares similar CPU and analog features.
