Frequently Asked Questions
How much Flash memory does the PIC32MX550F256H-I/MR provide, and is a separate bootloader partition available?
The PIC32MX550F256H-I/MR includes 256 KB of main program Flash along with an additional 3 KB dedicated boot Flash region. The boot Flash allows a protected bootloader to reside separately from application code, simplifying field firmware updates without risking corruption of the main 256 KB application space.
Does PIC32MX550F256H-I/MR support JTAG debugging, and how does boundary scan aid production testing?
Yes. The PIC32MX550F256H-I/MR supports JTAG boundary scan, enabling board-level interconnect testing on a populated PCB with 64 pins. In-circuit debuggers such as Microchip's PICkit 3 or MPLAB ICD 4 can connect via the JTAG port for single-step debugging and register inspection during firmware development.
What lead time should procurement expect for PIC32MX550F256H-I/MR, and how does it compare to longer-lead PIC32 variants?
The PIC32MX550F256H-I/MR carries a factory lead time of just 1 week, which is unusually short for a 32-bit MCU. This makes it attractive for just-in-time procurement strategies or urgent design-wins compared to PIC32 variants with 8-week or longer lead times that require advance buffer stocking.
