Microcontroller for embedded designs

The PIC24FJ256GL405-E PT TQFP48 is a microcontroller intended for engineers developing embedded control applications. Its 48-pin TQFP package suits space-constrained board layouts. The device targets industrial, automotive and consumer equipment requiring deterministic real-time performance.

256 KB flash with 24 KB RAM

On-chip program memory of 256 KB provides room for moderately complex firmware and lookup tables. The 24 KB data RAM supports typical buffer and state-machine needs. Very large graphics buffers or heavyweight protocol stacks would exceed the available memory headroom.

48-pin TQFP interface limits

The 48-pin package fixes the total I/O count and peripheral pin assignments. Designs needing more simultaneous communication channels or additional analogue inputs must migrate to a larger package or a different device. Pin multiplexing constraints are defined by the 48-lead footprint.

Questions about this item

Will the 48-pin TQFP footprint match the existing board layout I designed for a previous PIC24F device?

The PIC24FJ256GL405-E uses a standard 48-pin TQFP package, so any PCB laid out for that footprint will accept the new part without changes.

How can I confirm the 256 KB flash and 405 feature set are active after programming the device?

Read back the device ID and flash size registers through the ICSP interface; the returned values will match the 256 KB flash and 405 revision codes.

Does the reel or tray include any programming headers, decoupling capacitors or crystal oscillators?

The package contains only the PIC24FJ256GL405-E PT TQFP48 semiconductor; all programming headers, decoupling components and clock sources must be sourced separately.
