Hello,
Packages: 100-pin PZ (LQFP), 80-pin PN (LQFP), 64-pin PM (LQFP). The exact pins brought out depend on package; the datasheet shows the pin maps for each.
Count: Up to 55 individually programmable, multiplexed GPIO pins on F28003x devices (plus 23 digital inputs on analog pins and 2 AGPIO that can be used as digital I/O), with the subset bonded out varying by package. See the “Pin Configuration and Functions” tables/figures for your package (PZ/PN/PM).
GPIOs are numbered GPIO0… (device-specific upper bound). Internally they’re grouped by ports:
Port A: GPIO0–GPIO31
Port B: GPIO32–GPIO63
Port C: GPIO64–GPIO95 (only a subset exists/bonds out on F28003x)
Best Regards,
Masoud
