3.1.1.1 TMS320F28004x

The earliest microcontroller in this family of entry and mid-performance devices is the TMS320F28004x. It features a single-precision Floating-Point Unit (FPU) and a Trigonometric Math Unit (TMU), as well as Viterbi/Complex Math Unit (VCU-I). This device runs at 100 MHz, has 100 KB of random-access memory (RAM), and is equipped with 128 KB or 256 KB of flash memory, depending on the package. This device comes in a 56-pin, 64-pin, and 100-pin package options which sport between 24 and 40 GPIO inputs and between 12 and 21 AIO inputs. It also features 4 configurable logic block (CLB) tiles and a programmable control law accelerator (CLA) clocked at 100 MHz.

In addition to the standard peripherals, the F28004x MCU contains 4–7 programmable gain amplifiers (PGA). It also has support for high-resolution CAPs and high-resolution PWMs on specified pins, and it contains 3 to 4 sigma delta filter modules (SDFM).
