Product details
Overview
F2800155QRHBRQ1 from Texas Instruments is an automotive-grade real-time microcontroller featuring dual 32-bit C28x CPUs in lockstep at 120MHz, IEEE 754 FPU, TMU, and VCRC engine. It integrates 128KB ECC-protected flash, 36KB ECC/parity-protected RAM, two 4MSPS 12-bit ADCs, 14 ePWM channels (4 with 150ps resolution), one CAN FD/MCAN port, and functional safety certification up to ASIL B for motor control in DC/DC converters and inverter systems.
For engineers reviewing the F2800155QRHBRQ1 datasheet, F2800155QRHBRQ1 pinout, F2800155QRHBRQ1 application, or F2800155QRHBRQ1 equivalent, key selection criteria include lockstep CPU architecture, ASIL B qualification, 120MHz deterministic execution, integrated analog signal chain with post-processing blocks, and automotive-qualified 32-pin VQFN packaging with –40°C to 125°C operation.
Technical Context
The F2800155QRHBRQ1 implements a dual-core lockstep C28x architecture with hardware-level fault detection, enabling systematic ASIL B compliance without software overhead. Its analog subsystem tightly couples two 4MSPS ADCs with four PPB per ADC and three CMPSS_LITE modules with 9.5-bit DACs for real-time voltage/current monitoring in power stages.
Control peripherals include 14 ePWM channels (4 high-resolution), three eCAP modules, two eQEP modules supporting CW/CCW, and embedded pattern generation for gate drive sequencing. Communication is supported via one MCAN, one PMBus, two I²C, three SCI, one LIN, and one SPI interface - all accessible on its 32-pin RHB package with pin-muxing flexibility.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F2800157-Q1 | 256KB flash, same 120MHz dual-lockstep CPU, identical peripheral set, but offered in 80/64/48-pin packages only | Higher memory capacity supports larger control algorithms and OTA update partitions; not available in 32-pin RHB | Select when >128KB flash is required and board layout allows larger package |
| TMS320F2800153-Q1 | 64KB flash, same 32-pin RHB package, identical temp range and ASIL B rating, but reduced ADC channels (11) and no HRPWM | Suitable for cost-optimized body electronics or simpler motor control where 150ps timing resolution is unnecessary | Select when flash requirement is ≤64KB and high-resolution PWM is not needed |
Compared with F2800155QRHBRQ1, the F2800157-Q1 offers double flash capacity for complex control stacks but requires PCB redesign for larger packages, while the F2800153-Q1 retains the same 32-pin footprint and ASIL B rating at lower memory and PWM capability - making it a size-compatible alternative for less demanding applications.
