Product details
Overview
F2800157SPMR from Texas Instruments is a dual-core C28x real-time microcontroller operating at 120MHz, featuring IEEE 754 FPU, Trigonometric Math Unit (TMU), and 256KB ECC-protected flash. It integrates two 4MSPS 12-bit ADCs, 14 ePWM channels (4 with 150ps resolution), and functional safety certification up to ASIL B for automotive motor control and digital power applications.
For engineers reviewing the F2800157SPMR datasheet, F2800157SPMR pinout, F2800157SPMR application, or F2800157SPMR equivalent, key selection criteria include lockstep dual-CPU architecture, 120MHz deterministic execution, integrated CMPSS with 12-bit DAC, CAN FD support, and AEC-Q100 Grade 1 qualification in 64-pin LQFP (PM) package.
Technical Context
The F2800157SPMR implements dual TMS320C28x CPUs in hardware lockstep for fault detection, with dedicated VCRC engine and TMU acceleration for real-time control math. Its analog subsystem tightly couples two 12-bit ADCs (4MSPS) and one CMPSS with 12-bit ramp DAC to ePWM modules for closed-loop timing-critical power conversion.
System-level safety is enforced via DCSM security zones, JTAGLOCK, zero-pin boot, and dual-clock comparator (DCC). The device supports multiple boot modes including internal flash, SCI, and SPI, with brownout reset and windowed watchdog timer for robust operation in automotive and industrial environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F2800155SPMR | 128KB flash, same 120MHz dual-C28x core, identical peripheral set except reduced memory footprint | Suitable for cost-sensitive industrial drives where firmware size <128KB and no future feature expansion needed | Select when full 256KB flash is unnecessary and BOM cost reduction is prioritized over firmware headroom |
| TMS320F2800157PNSR | Same silicon die, but in 80-pin LQFP (PN) package with 52 GPIO and 21 ADC channels vs. 37 GPIO/10 ADC in PM | Required for designs needing maximum analog/digital I/O count, such as multi-sensor motor control or complex power topology management | Choose when additional GPIO, ADC channels, or CAN FD + legacy CAN dual-bus capability is mandatory |
Compared with F2800155SPMR, F2800157SPMR provides double flash capacity for larger control algorithms and dual-firmware storage; compared with F2800157PNSR, it trades I/O count for smaller PCB area and lower assembly cost in space-constrained automotive modules.

FAQ
What is the functional safety certification status of the F2800157SPMR?
The F2800157SPMR is ISO 26262 certified up to ASIL B by TÜV SÜD and IEC 61508 certified up to SIL 2. It includes hardware safety mechanisms such as lockstep CPU comparison, memory ECC, DCC, and windowed watchdog-enabling systematic development of safety-critical automotive and industrial systems without requiring external safety monitors. Documentation supporting ISO 26262 and IEC 61508 integration is provided by Texas Instruments.
Does the F2800157SPMR support both CAN and CAN FD interfaces simultaneously?
Yes, the F2800157SPMR integrates one legacy CAN (DCAN) port and one Controller Area Network with Flexible Data-Rate (MCAN) port. These operate independently, allowing concurrent use-for example, CAN for legacy vehicle network communication and CAN FD for high-speed firmware updates or diagnostic data streaming. Both interfaces are accessible in the 64-pin PM package with dedicated pin assignments per TI's pin multiplexing table.
What is the maximum ADC sampling rate and channel count supported by the F2800157SPMR in the 64-pin package?
In the 64-pin LQFP (PM) package, the F2800157SPMR supports two 12-bit ADCs each operating at 4 MSPS, with up to 21 external input channels (11 shared with GPIO). The actual usable channel count is 10 analog-capable pins (AIO) plus 27 GPIOs that can be configured for digital input-providing flexibility for mixed-signal acquisition in compact motor control designs.
How does the HRPWM capability of the F2800157SPMR improve gate driver timing precision?
The F2800157SPMR provides four ePWM channels with 150 ps resolution, enabling sub-nanosecond dead-time control critical for SiC and GaN power devices. This eliminates external delay circuits and reduces propagation uncertainty in high-frequency switching topologies-directly improving efficiency and thermal performance in 100+ kHz power converters.
Is the F2800157SPMR pin-compatible with other members of the F280015x family?
The F2800157SPMR shares identical pinout and electrical characteristics with F2800155SPMR and F2800153SPMR in the 64-pin PM package. However, it is not pin-compatible with 80-pin PN or 48-pin PHP variants due to differing pin counts and signal allocations. Migration between S-grade (F2800157SPMR) and Q-grade (F2800157QPNSR) parts requires validation of temperature derating and qualification documentation but retains mechanical and electrical compatibility.
