DSPIC33EP256GM310T-I/PT

Microcontrollers Overview

The dsPIC33EP256GM310T-I/PT is a 16-bit Digital Signal Controller featuring a dsPIC33E CPU core. It includes 256 KB of Flash program memory and 32 KB of RAM. The device supports operation up to 70 MIPS at frequencies up to 70 MHz within the industrial temperature range of -40°C to +85°C, powered by a 3.0V to 3.6V supply. It integrates advanced analog peripherals including dual ADCs, four Op-Amps/Comparators, CTMU, and PTG. Communication interfaces consist of four UARTs, three SPIs, two I2Cs, and two CAN modules. Motor control capabilities are provided by up to 12 PWM outputs, eight Input Capture modules, and two QEI modules.

Microcontrollers Feature Summary

• Advanced analog subsystem with dual configurable ADCs, op-amps, comparators, and charge time measurement unit
• Comprehensive communication suite including multiple UART, SPI, I2C, and CAN interfaces with CRC support
• Flexible timer architecture with general-purpose timers, input capture, output compare, and quadrature encoder interfaces

Microcontrollers Applications

• Brushless DC (BLDC) and Permanent Magnet Synchronous Motor (PMSM) drives
• AC Induction Motor (ACIM) and Switched Reluctance Motor (SRM) control
• Power factor correction (PFC) and AC/DC or DC/DC converters
• Industrial lighting systems requiring precise dimming and control

Microcontrollers Procurement Notes

Verify the specific suffix 'T-I/PT' against the manufacturer's current product status documentation. Confirm that the TFBGA package type matches the target PCB footprint requirements. Ensure the industrial temperature grade (-40°C to +85°C) aligns with the operational environment specifications. Cross-reference the AEC-Q100 qualification status if automotive compliance is required for the final assembly.

Microcontrollers Selection Notes

Select this component when high-performance digital signal processing is combined with complex motor control requirements. The integrated high-speed PWM and analog features reduce external component count for power electronics designs. Verify that the available I/O pins and peripheral counts meet the system interface needs without requiring additional controllers.

Microcontrollers Part Context
