Overview

F2800157SPHPR from Texas Instruments is a dual-core C28x real-time microcontroller operating at 120MHz, featuring IEEE 754 FPU, Trigonometric Math Unit (TMU), and VCRC engine for deterministic control. It integrates 256KB ECC-protected flash, 36KB ECC/parity-protected RAM, and supports ASIL B functional safety certification. It targets high-precision power electronics control in automotive DC/DC converters and industrial motor drives.

For engineers reviewing the F2800157SPHPR datasheet, F2800157SPHPR pinout, F2800157SPHPR application, or F2800157SPHPR equivalent, key selection criteria include lockstep dual-CPU architecture, 4-channel HRPWM with 150ps resolution, dual 4MSPS 12-bit ADCs with PPB post-processing, CAN FD interface, and AEC-Q100 Grade 1 qualification for automotive use.

Technical Context

The F2800157SPHPR implements two synchronized TMS320C28x CPUs in lockstep to meet ASIL B requirements without significant software overhead. Its real-time subsystem includes dedicated accelerators: TMU for sine/cosine and arctangent, and VCRC for fast checksum computation on control loops.

It features dual 12-bit ADCs with up to 21 external channels and four integrated Post-Processing Blocks per ADC for hardware-based filtering and thresholding. The analog subsystem is tightly coupled with 14 ePWM channels (4 with high-resolution capability) and one full-featured CMPSS with 12-bit ramp DAC for closed-loop protection.

FAQ

What is the maximum operating temperature range for the F2800157SPHPR?

The F2800157SPHPR is rated for operation from –40°C to +125°C ambient temperature (TA). This specification applies to the non-automotive "S" grade variant, which matches the F2800157SPHPR part number. The device uses internal thermal monitoring and brownout reset circuitry to maintain reliability across this full industrial-automotive range. The F2800157SPHPR does not carry AEC-Q100 qualification but shares the same silicon and thermal design as the qualified Q1 variants.

Does the F2800157SPHPR support CAN FD communication?

Yes, the F2800157SPHPR includes one Controller Area Network with Flexible Data-Rate (CAN FD/MCAN) bus port compliant with ISO 11898-1:2015. It supports data rates up to 5 Mbps in the data phase, frame payloads up to 64 bytes, and CRC protection for both arbitration and data fields. The F2800157SPHPR implements full MCAN protocol handling in hardware, including message RAM, filters, and transmit/receive FIFOs-enabling robust communication in automotive and industrial networks.

How many high-resolution PWM channels does the F2800157SPHPR provide?

The F2800157SPHPR provides four high-resolution ePWM channels (ePWM1–ePWM4), each capable of 150ps time resolution. These channels support advanced features including programmable dead-band, trip-zone inputs, and event-triggered ADC start. The high-resolution capability is implemented via auxiliary time-base counters and digital interpolators, enabling precise gate timing for wide-bandgap power devices. All 14 ePWM channels are available on the 48-pin PHP package, with HR capability limited to the first four.

Is the F2800157SPHPR pin-compatible with other F280015x family members?

No, the F2800157SPHPR is not pin-compatible with other F280015x variants due to its 48-pin HTQFP (PHP) package. While it shares the same internal peripheral architecture as the 80-pin PN and 64-pin PM variants, pin assignments differ significantly across packages. For example, analog inputs A12–A19 and several ePWM signals are unavailable on the PHP package. Migration requires PCB redesign; however, firmware is largely portable across the F280015x family using TI's C2000Ware driver libraries.

What security features are implemented in the F2800157SPHPR?

The F2800157SPHPR implements three layered security features: JTAGLOCK disables debug access after programming, zero-pin boot prevents unauthorized firmware execution at startup, and dual-zone security partitions flash and RAM into secure/non-secure regions with hardware-enforced access control. These features are enabled via DCSM (Device Configuration Security Module) registers and supported by TI's Secure Boot ROM. The F2800157SPHPR does not include cryptographic accelerators like AES engines found in higher-tier C2000 devices.
