I recently worked on a new car specification project and came into contact with TMS320F280049 for the first time. I recorded the minimum system schematic design.

1 Overview

The third generation C2000™ device family is a powerful microcontroller designed for complex systems requiring real-time control, which is particularly important in many automotive and industrial applications. These devices feature high-speed, low-latency integrated analog and control peripherals, allowing users to integrate their control and communications designs.

The C2000 series of real-time microcontrollers are available in a variety of high-performance packages with different pin packages, flash sizes, performance and feature sets. This extensive product range supports processing, detection and actuation applications. All TMS320F2800x devices (F280013x, F28002x, F28003x and F28004x) feature the industry-leading TMS320C28x 32-bit digital signal processor (DSP) core running at 100MHz or higher. This, along with a mathematically tuned instruction set, enables C2000 MCUs to run floating-point or fixed-point code in ultra-low-latency control systems. In terms of performance, entry-level and mid-performance F2800x devices have flash sizes up to 384KB and RAM sizes up to 100KB.

The figure shows a typical C2000-based control system block diagram:

The microcontroller is powered by a power supply system that adapts to the primary voltage rails and includes a 3.3V analog voltage (VDDA), a 3.3V digital voltage (VDDIO), and a 1.2V core supply rail (VDD). C2000 devices provide rich peripheral support. C2000-based systems usually include the following circuits connected to the MCU: power management, signal conditioning of analog inputs, crystal or external oscillator, reset circuit, communication transceiver, external digital IO pins interface, digital sensing, pulse width modulation (PWM) interface/driver, and any other required support circuitry.

3.1 Packaging and device decisions

Identifying the correct C2000 device is the first step in designing and integrating TI's C2000 platform into a system. In addition to cost and availability, peripheral support is one of the most important deciding factors when considering which TMS320F2800x device to implement in a system. The performance of C2000 devices is generally related to the part number (F28002x is the entry-level performance chip, F28004x is the mid-range performance chip). Additionally, newer devices often include new onboard peripherals or updated versions of existing peripherals. Each device is available in a variety of packages and form factors. For more information on each chip package size, see the Mechanical Data section in the device-specific data sheets.
