Product details
Overview
TMS320F2800157SPHP from Texas Instruments is a dual-core C28x real-time microcontroller with lockstep safety architecture, 120MHz operation, 256KB ECC-protected flash, 36KB ECC/parity-protected RAM, and integrated 4MSPS 12-bit ADCs-designed for automotive motor control, DC/DC converters, and BMS applications requiring ASIL B compliance.
For engineers reviewing the TMS320F2800157SPHP datasheet, TMS320F2800157SPHP pinout, TMS320F2800157SPHP application, or TMS320F2800157SPHP equivalent, this page delivers verified functional safety features, confirmed HTQFP-48 package mapping, validated ePWM/ADC/CAN FD peripheral integration, and precise GPIO-to-analog multiplexing behavior per TI SPRSP68D Rev. November 2025.
Technical Context
The TMS320F2800157SPHP implements dual 32-bit C28x CPUs in hardware lockstep with IEEE 754 FPU, TMU, and VCRC acceleration to enable deterministic real-time control while meeting ISO 26262 ASIL B requirements without software overhead. Its analog subsystem tightly couples two 4MSPS ADCs with four PPB post-processing blocks per converter and one 12-bit ramp DAC CMPSS module.
System-level timing uses dual internal 10MHz oscillators plus crystal/external clock support, with DCC, windowed watchdog, and missing-clock detection. The device supports zero-pin boot, JTAGLOCK, and dual-zone security, and operates at 1.2V core / 3.3V I/O with brownout reset and internal VREG.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F2800155SPHP | 128KB flash, same 120MHz dual-C28x lockstep core, identical HTQFP-48 package and peripheral set except reduced flash size. | Suitable for cost-sensitive industrial motor drives where firmware footprint <128KB suffices and ASIL B certification is not required. | Select when flash headroom and functional safety certification are non-critical; retains full pin compatibility and software migration path. |
| TMS320F2800157PNSR | Same core, flash, and peripherals but in 80-pin LQFP (PN) package with 52 GPIOs and full 21-channel ADC support (vs. 18 channels on PHP). | Better suited for complex multi-sensor systems like radar ECU or 3-phase OBC requiring maximum analog/digital I/O count. | Choose when additional GPIOs, ADC channels, or thermal margin beyond HTQFP-48 are needed; requires PCB redesign. |
Compared with TMS320F2800155SPHP, the TMS320F2800157SPHP provides double flash capacity and ISO 26262 ASIL B certification; compared with TMS320F2800157PNSR, it trades I/O count and thermal performance for smaller board area and lower assembly cost in space-constrained modules.
