DSPIC33EV64GM102-I/SS

Microcontrollers Overview

The DSPIC33EV64GM102-I/SS is a 16-bit Digital Signal Controller from the dsPIC33EVXXXGM00X/10X family, manufactured by Microchip Technology. It features a 16-bit dsPIC33E CPU with code-efficient architecture and dual 40-bit accumulators. The device includes 64 KB of Flash program memory and 8 KB of SRAM. Operating conditions support DC to 70 MIPS at 4.5V to 5.5V within the 0°C to +85°C range, or up to 60 MIPS in the -40°C to +125°C extended temperature range. It integrates advanced analog peripherals including Op Amps, Comparators, CTMU, and a high-speed ADC.

Microcontrollers Feature Summary

• Features a 16-bit dsPIC33E CPU core with single-cycle MAC operations and hardware divide capabilities for efficient digital signal processing.
• Includes integrated safety mechanisms such as Error Code Correction (ECC) for Flash memory and intermediate security with boot flash segments.
• Provides flexible PWM generation with primary master time base inputs, dead time control, and fault inputs for motor drive applications.
• Supports automotive communication standards through an integrated SENT module alongside standard UART, SPI, I2C, and CAN interfaces.

Microcontrollers Applications

• Brushless Direct Current (BLDC), Permanent Magnet Synchronous Motor (PMSM), and AC Induction Motor (ACIM) control
• Automotive sensor systems utilizing Single-Edge Nibble Transmission (SENT) protocols
• Power conversion systems including DC/DC converters, AC/DC inverters, and Power Factor Correction (PFC)
• Industrial control systems requiring high-reliability operation and Class B safety library support

Microcontrollers Procurement Notes

Verify the specific ordering suffix 'I/SS' corresponds to the SSOP-28 package and industrial temperature rating (-40°C to +125°C). Confirm that the '102' designation indicates the inclusion of the CAN module, distinguishing it from the '002' variant which lacks CAN. Ensure compatibility with 4.5V to 5.5V supply rails and validate pinout requirements against the 28-pin SPDIP/SOIC/SSOP diagram provided in the datasheet.

Microcontrollers Selection Notes

Select this component when a 5V-compatible 16-bit controller with integrated CAN and SENT capabilities is required. It is suitable for designs needing robust analog features like Op Amps and CTMU without external components. Consider the extended temperature grade if operation above 85°C ambient is expected, noting the reduced maximum clock frequency at higher temperatures compared to the commercial grade.

Microcontrollers Part Context

This device belongs to the dsPIC33EVXXXGM00X/10X family, designed for cost-sensitive embedded applications requiring high performance and advanced analog integration. The 'EV' series emphasizes energy efficiency and value, while the 'GM' suffix denotes specific peripheral configurations. The '102' model specifically adds Controller Area Network (CAN) functionality compared to the base '002' models in the same memory footprint.

Microcontrollers Replacement Considerations

The DSPIC33EV64GM002-I/SS serves as a direct substitute if CAN communication is not required, offering identical memory and pinout but lacking the CAN module. Other family members like the DSPIC33EV32GM102 share similar architectures but differ in memory size and pin counts.
