Texas Instruments TMS320F28377SPZPS

Overview

TMS320F28377SPZPS from Texas Instruments is a 32-bit floating-point real-time microcontroller featuring a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), Viterbi/Complex Math Unit (VCU-II), and a parallel 200MHz Control Law Accelerator (CLA). It integrates four 16-/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels with 16 high-resolution HRPWM outputs, dual CAN 2.0B interfaces, USB 2.0 (MAC+PHY), and 169 GPIOs - deployed in industrial motor drives, solar inverters, and EV charging power modules.

For engineers reviewing the TMS320F28377SPZPS datasheet, TMS320F28377SPZPS pinout, TMS320F28377SPZPS application, or TMS320F28377SPZPS equivalent, key selection criteria include CLA coprocessor independence, dual-zone security for third-party code protection, ECC-protected 1MB flash and 164KB RAM, functional safety certification up to ASIL B/SIL 2, and support for isolated current sensing via SDFM + sigma-delta modulators.

Technical Context

The TMS320F28377SPZPS implements a single-CPU subsystem architecture (vs. dual-CPU F2837xD), with the C28x core and CLA executing concurrently at 200MHz - enabling deterministic response to time-critical control loops while offloading math-intensive tasks like torque calculation or PWM update. Its analog subsystem includes hardware-accelerated ADC post-processing (offset calibration, setpoint error, windowed comparators with DAC references) and eight SDFM input channels supporting fast overcurrent detection.

System-level integration is enhanced by two EMIFs (ASRAM/SDRAM), six-channel DMA, configurable logic blocks (CLB) for position manager augmentation, and peripheral boot capability. The device operates at 1.2V core / 3.3V I/O, supports multiple low-power modes with external wakeup, and features dual internal 10MHz oscillators plus on-chip crystal oscillator for clock redundancy.

FAQ

What is the maximum operating junction temperature for the TMS320F28377SPZPS?

The TMS320F28377SPZPS is rated for a junction temperature range of –40°C to 125°C, denoted by the 'S' suffix in its part number. This extended temperature grade supports deployment in high-ambient environments such as under-hood automotive power modules or industrial enclosures without forced cooling. Thermal design must ensure the exposed thermal pad on the HTQFP package is properly soldered and connected to a sufficient copper area per TI's PCB layout guidelines.

Does the TMS320F28377SPZPS support functional safety certification for automotive use?

Yes, the TMS320F28377SPZPS is certified to ISO 26262 ASIL B and IEC 61508 SIL 2 by TÜV SÜD. While it carries the 'S' temperature grade (–40°C to 125°C), it is not AEC-Q100 qualified - that designation applies only to the TMS320F28377S-Q1 variant. For automotive applications requiring formal qualification, the Q1 version must be selected; however, the TMS320F28377SPZPS remains suitable for non-automotive safety-critical systems like industrial UPS or energy storage PCS.

How many ADC modules does the TMS320F28377SPZPS integrate, and what are their key capabilities?

The TMS320F28377SPZPS integrates four independent 16-/12-bit analog-to-digital converters. Each supports 1.1MSPS in 16-bit differential mode (12 external channels) or 3.5MSPS in 12-bit single-ended mode (24 external channels), with dedicated sample-and-hold circuitry. Hardware post-processing includes saturating offset calibration, setpoint error calculation, and eight windowed comparators with 12-bit DAC references - enabling real-time protection without CPU intervention.

Can the TMS320F28377SPZPS execute code independently on both the main CPU and CLA simultaneously?

Yes, the TMS320F28377SPZPS features a fully independent Control Law Accelerator (CLA) that runs at 200MHz - identical to the main C28x CPU clock - and executes floating-point code triggered by peripheral events (e.g., ADC end-of-conversion, PWM timer overflow). The CLA has its own program/data memory, registers, and interrupt vector table, allowing true parallel processing. This architecture enables the main CPU to handle communications and diagnostics while the CLA maintains deterministic control loop timing.

What communication interfaces are available on the TMS320F28377SPZPS in the 100-pin HTQFP package?

In the PZP (100-pin HTQFP) package, the TMS320F28377SPZPS provides two CAN 2.0B modules, two I²C interfaces, three SPI ports, four SCI/UART channels, two McBSPs, one USB 2.0 port (with integrated PHY), and one uPP interface. All are accessible on package pins - though some peripheral instances may be multiplexed or limited by pin count. The device supports pin-bootable operation for CAN, SPI, SCI, and I²C, simplifying firmware recovery and configuration flexibility.
