Texas Instruments TMS320F28030PNS

Overview

TMS320F28030PNS from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated ePWM, 12-bit ADC (16-channel, 2 MSPS), three 32-bit CPU timers, and on-chip 16KB Flash/6KB SARAM. It operates from a single 3.3V supply, supports JTAG boundary scan per IEEE 1149.1, and targets motor control and digital power applications requiring deterministic low-latency execution.

For engineers reviewing the TMS320F28030PNS datasheet, TMS320F28030PNS pinout, TMS320F28030PNS application, or TMS320F28030PNS equivalent, key selection criteria include its LQFP-80 package, absence of CLA accelerator, 16KB Flash memory size, 45 GPIO pins with input filtering, and compatibility with C2000™ real-time control ecosystem for inverter and servo drive designs.

Technical Context

The TMS320F28030PNS implements a Harvard-architecture C28x CPU executing at 60 MHz (16.67 ns cycle time) with unified memory programming model and atomic instruction support. Its real-time capability is reinforced by Peripheral Interrupt Expansion (PIE) handling all peripheral interrupts and fast interrupt response optimized for closed-loop control.

It integrates analog peripherals including a 12-bit ADC with 16 input channels, dual sample-and-hold, fixed 0–3.3V full-scale range, and ratio-metric VREFHI/VREFLO references. Control peripherals include 14 ePWM channels, one eCAP module, one eQEP module, three comparators with internal 10-bit references, and HRPWM for dual-edge modulation in power stage timing.

FAQ

What is the maximum operating frequency of the TMS320F28030PNS?

The TMS320F28030PNS operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67 ns instruction cycle time. This speed is achieved using the C28x 32-bit fixed-point core and is supported across its full industrial temperature range (–40°C to 105°C). The TMS320F28030PNS does not include a CLA accelerator, so all real-time computation is handled by the main CPU.

Does the TMS320F28030PNS support JTAG debugging?

Yes, the TMS320F28030PNS fully supports IEEE 1149.1-1990 JTAG boundary scan with dedicated TCK, TMS, TDI, TDO, and TRST pins. TRST requires an external 2.2-kΩ pulldown resistor for proper functional mode operation. Debug capabilities include real-time analysis, hardware breakpoints, and emulation features accessible through TI's C2000™ Code Generation Tools and XDS100v3/XDS200 debug probes.

What analog peripherals are integrated into the TMS320F28030PNS?

The TMS320F28030PNS integrates a 12-bit, 16-channel, 2 MSPS ADC with dual sample-and-hold, ratio-metric VREFHI/VREFLO referencing, and fixed 0–3.3V full-scale range. It also includes three analog comparators with internal 10-bit DAC references, an on-chip temperature sensor, and dedicated analog I/O pins (AIO0–AIO14) routed to comparator and ADC inputs.

Is the TMS320F28030PNS pin-compatible with other F2803x devices in LQFP-80 package?

Yes, the TMS320F28030PNS shares identical pinout and package dimensions (PN LQFP-80, 12.0 mm × 12.0 mm) with TMS320F28031PNS, TMS320F28032PNS, TMS320F28033PNS, TMS320F28034PNS, and TMS320F28035PNS. Peripheral availability differs across variants (e.g., CLA presence, Flash size, ePWM count), but PCB layout and signal routing remain interchangeable within this package group.

What is the Flash memory capacity of the TMS320F28030PNS?

The TMS320F28030PNS contains 16 KB of on-chip Flash memory organized as 16-bit words. This memory is secured via the code-security module with 128-bit key locking and supports in-system programming. It is sufficient for compact real-time control firmware such as sensorless FOC for BLDC motors or digital PFC control loops.
