Texas Instruments TMS320F28023PTS

Overview

TMS320F28023PTS from Texas Instruments is a 50-MHz C28x-core real-time control microcontroller in 48-pin LQFP package, featuring 8 kB flash, 3 kB SARAM, 32-bit CPU timers, ePWM with HRPWM, 12-bit ADC (7-channel), and integrated comparators - designed for motor control and digital power conversion in industrial inverters and BLDC drives.

For engineers reviewing the TMS320F28023PTS datasheet, TMS320F28023PTS pinout, TMS320F28023PTS application, or TMS320F28023PTS equivalent, key selection considerations include its 50-MHz deterministic execution, single 3.3-V supply operation, on-chip VREG, and support for closed-loop timing-critical functions like PWM synchronization and ADC-triggered capture in compact embedded systems.

Technical Context

The TMS320F28023PTS implements the TMS320C28x 32-bit CPU core with Harvard architecture, atomic instructions, and unified memory model - enabling efficient C/C++ code execution and fast interrupt response (<100 ns latency). It integrates a Peripheral Interrupt Expansion (PIE) block to manage up to 96 peripheral interrupts with vectorized dispatch.

Its real-time control subsystem includes four ePWM modules (each with independent 16-bit timer and dual-edge HRPWM capability), two analog comparators with internal 10-bit references, and a 12-bit ADC with 500-ns conversion time and dual sample-and-hold - all synchronized via EPWMSYNCI/EPWMSYNCO signals for precise timing alignment in motor phase control.

FAQ

What is the maximum operating frequency of the TMS320F28023PTS?

The TMS320F28023PTS operates at a maximum CPU frequency of 50 MHz, delivering a 20-ns instruction cycle time. This speed is factory-configured and supported across its full –40°C to 125°C operating range. The device uses an internal PLL to derive SYSCLK from either the on-chip oscillator or external clock source, and the TMS320F28023PTS maintains timing compliance without external frequency multipliers or external crystal load adjustments.

Does the TMS320F28023PTS include on-chip flash memory, and how much is available?

Yes, the TMS320F28023PTS includes 8K × 16-bit (16 kB) of on-chip flash memory, organized for zero-wait-state execution at 50 MHz. This flash is secured via the device's code-security module and supports in-system programming via JTAG or SCI bootloader. The TMS320F28023PTS also includes 1K × 16-bit OTP memory for critical calibration data and 3K × 16-bit SARAM for high-speed runtime variables.

How many PWM channels does the TMS320F28023PTS support, and what advanced features are included?

The TMS320F28023PTS supports eight ePWM channels across four modules (ePWM1–ePWM4), with four of those channels (ePWM1A/2A/3A/4A) enhanced for high-resolution operation (HRPWM). Each ePWM module includes independent 16-bit time-base counters, configurable dead-band generation, trip-zone protection inputs (TZ1–TZ3), and synchronization signals (EPWMSYNCI/EPWMSYNCO) - all accessible on the 48-pin LQFP package used by the TMS320F28023PTS.

What analog peripherals are integrated into the TMS320F28023PTS?

The TMS320F28023PTS integrates a 12-bit, 7-channel ADC with 500-ns conversion time and dual sample-and-hold capability, two analog comparators with internal 10-bit DAC references, and an on-chip temperature sensor. All analog inputs (ADCINA0–ADCINA6, COMP1A/1B, COMP2A/2B) are accessible on dedicated pins in the 48-pin LQFP package, and the TMS320F28023PTS supports ratio-metric referencing using VREFHI/VREFLO for improved accuracy in varying supply conditions.

Is the TMS320F28023PTS pin-compatible with other devices in the F2802x family?

Yes, the TMS320F28023PTS shares identical pinout and package (48-pin LQFP) with other PT-suffixed F2802x variants including TMS320F28026PT, TMS320F28027PT, and TMS320F28022PT. This allows direct PCB reuse across performance tiers - for example, upgrading from TMS320F28023PTS to TMS320F28026PT requires only firmware and flash configuration changes, with no layout modification needed for the TMS320F28023PTS footprint.
