Build with TMS320F28030 — Datasheet Specs & AI Design Help

00 — Overview

What the TMS320F28030 does

The TMS320F2803x Piccolo microcontrollers are 32-bit devices featuring a C28x CPU, a 60MHz clock speed, and a 16-bit Control Law Accelerator. This family spans six part numbers (F28030 through F28035) available in 56-pin VQFN, 64-pin TQFP, and 80-pin LQFP packages. Key specifications include a single 3.3-V supply, up to 45 programmable GPIO pins, and integrated peripherals like ePWM, eCAP, and eQEP modules. Engineers typically use these controllers for smart grid applications, solar microinverters, switch-mode power supplies, and white goods. The architecture supports code security, low-power operation, and advanced emulation features without requiring analog support pins.
