TMX5702125BPGEQQ1 from Texas Instruments is an automotive-grade 32-bit RISC flash microcontroller featuring dual lockstep ARM Cortex-R4F CPUs, 2MB ECC-protected flash, 192KB ECC-protected RAM, and integrated safety mechanisms including BIST, parity-protected peripherals, and error signaling. It delivers 298 DMIPS at 180 MHz and targets ASIL-D functional safety applications such as electric power steering and battery management systems.
For engineers reviewing the TMX5702125BPGEQQ1 datasheet, TMX5702125BPGEQQ1 pinout, TMX5702125BPGEQQ1 application, or TMX5702125BPGEQQ1 equivalent, key selection criteria include dual-CPU lockstep architecture, 144-pin LQFP (PGE) package, CAN/FlexRay/DCAN interface support, N2HET timing coprocessor capability, and compliance with ISO 26262 ASIL-D requirements.
Technical Context
The TMX5702125BPGEQQ1 implements a safety-critical dual-core lockstep execution model with built-in CPU and memory BIST, ECC on flash and SRAM, and parity protection across peripheral memories. Its FMPLL clock module supports up to 180 MHz system operation with slip detection, while the dedicated FlexRay Transfer Unit (FTU) enables autonomous data movement between FlexRay buffers and main memory under MPU control.
It integrates two 12-bit MibADC modules (24 total channels, 64-word parity-protected buffer each), two Next Generation High-End Timer (N2HET) modules (N2HET1: 32 channels; N2HET2: 18 channels), and three DCAN controllers compliant with CAN 2.0B protocol at up to 1 Mbps - all operating within a unified memory map and protected by a 12-region MPU.
