dsPIC33EV256GM004-I PT TQFP44 MCU

The YINGHUA dsPIC33EV256GM004-I PT TQFP44 is a new microcontroller intended for embedded control applications. Engineers working on motor control or power conversion designs will find this 44-pin device suitable. It arrives in factory condition ready for production or prototyping use.

Surface-mount TQFP44 installation

The component uses a TQFP44 package requiring surface-mount soldering onto a printed circuit board. Standard reflow profiles apply for the 44 leads. Common issues include solder bridging between fine-pitch pins and insufficient wetting on ground pads. Automated optical inspection is recommended after assembly.

44-pin package and 256 memory limits

The TQFP44 footprint provides 44 pins for I/O and power connections, which constrains the number of external peripherals. On-chip program memory of 256 units limits firmware size for complex algorithms. Designers needing more I/O or larger code space must select a device with a higher pin count or greater memory.

Questions about this item

How do I verify the dsPIC33EV256GM004-I PT TQFP44 is running after soldering it to the board?

Apply power, then confirm the oscillator starts and the device responds to a simple I/O toggle or debugger connection.

What comes with the dsPIC33EV256GM004-I PT TQFP44 and what must I source separately?

The package contains the 44-pin TQFP microcontroller only; a PCB, decoupling capacitors, crystal or resonator, programmer and power supply must be sourced separately.

Which dsPIC33EV256GM004-I PT TQFP44 variant should I choose for my design?

The part is offered in a single 44-pin TQFP package with 256 KB flash; select it when your layout and memory needs match that pin count and capacity.
