TMS320F28023-Q1
TMS320F28023-Q1 - 50MHz C2000 MCU, 64KB Flash | TI
The TMS320F28023-Q1 is an automotive-grade C2000™ 32-bit microcontroller from Texas Instruments, part of the Piccolo™ F2802x family. It features a C28x core running at up to 50 MHz, 64 KB of flash memory, and 12 KB of SRAM. The device is optimized for real-time control applications, offering high-performance processing, sensing, and actuation capabilities in a low pin-count package. It operates from a single 3.3V supply thanks to an internal voltage regulator, simplifying power design.
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.
