TMS320F28023-Q1 Overview
A microcontroller (MCU) is a compact integrated circuit designed to govern a specific operation in an embedded system. It contains a processor core, memory, and programmable input/output peripherals. The C2000 family is a specialized line of MCUs from Texas Instruments tailored for real-time control, combining the C28x DSP core with integrated control peripherals such as ADCs, PWMs, and communication interfaces. This makes them ideal for closed-loop control systems where precise timing and deterministic execution are critical.
Key features of the TMS320F28023-Q1 include a 12-bit ADC with up to 16 channels, multiple PWM modules with dead-band generation, and a variety of communication interfaces including SPI, SCI (UART), and I2C. The device also includes a comparator subsystem and a programmable gain amplifier (PGA) for analog signal conditioning. The automotive qualification (AEC-Q100) ensures reliable operation in harsh environments, with an operating temperature range of -40°C to +125°C.
The architecture is based on the C28x core, which is a 32-bit fixed-point DSP optimized for control algorithms. It supports up to 50 MHz operation, providing 50 MIPS of processing power. The integrated memory includes 64 KB of flash and 12 KB of SRAM, with options for external memory expansion via the external interface (XINTF) on some variants. The device also features a boot ROM with factory-programmed bootloader routines, enabling flexible boot options.
Typical applications include automotive motor control (e.g., pumps, fans, and actuators), industrial drives, solar inverters, and digital power conversion. The TMS320F28023-Q1 is also used in sensing and signal processing applications where its high-speed ADC and PWM capabilities are essential. Its small package options, such as the 48-pin LQFP (PT) and 38-pin TSSOP (DA), make it suitable for space-constrained designs.
When designing with this MCU, ensure proper decoupling of the 3.3V supply and use the internal voltage regulator's output for the core logic. The ADC reference pins require careful layout to minimize noise. Additionally, the device supports JTAG and cJTAG for debugging, and it is compatible with TI's Code Composer Studio IDE and controlSUITE software libraries.

Key Differentiators
- Automotive AEC-Q100 qualification (vs TMS320F28023 (non-Q1))
- Larger memory than TMS320F28022-Q1 (vs TMS320F28022-Q1)
- Higher PWM channel count than TMS320F2802-Q1 (vs TMS320F2802-Q1)
Design Notes
The TMS320F28023-Q1 operates from a single 3.3V supply, with an internal voltage regulator generating the 1.8V core voltage. Ensure the 3.3V supply is clean and well-regulated, with a 10uF and 0.1uF decoupling capacitor placed close to the VDDIO pins. The internal regulator requires an external capacitor on the VREG output pin (typically 2.2uF) for stability. Refer to the datasheet for the recommended power supply circuit.
For optimal ADC performance, place the VREFHI and VREFLO pins with a low-impedance reference source and bypass capacitors (0.1uF and 10uF) close to the pins. Keep analog and digital ground planes separate and connect them at a single point. Route ADC input traces away from high-speed digital signals to minimize noise coupling. Use a solid ground plane under the MCU to reduce EMI.
A common pitfall is neglecting the boot mode configuration. The TMS320F28023-Q1 has multiple boot modes (e.g., flash, SCI, SPI) selected via GPIO pins. Ensure the boot mode pins are correctly set for your application to avoid unexpected boot behavior. Also, verify the crystal oscillator circuit (X1/X2) with appropriate load capacitors, as an incorrect crystal can prevent the MCU from starting.
