Product details
Overview
TMX5701227AZWTQQ1 from Texas Instruments is an automotive-grade 32-bit ARM Cortex-R4F safety microcontroller with dual lockstep CPUs, 1.25MB flash (ECC-protected), 192KB RAM (ECC-protected), and integrated safety features including BIST, error signaling, and voltage/clock monitoring. It delivers 298 DMIPS at 180 MHz and targets brake control, electric power steering, and HEV/EV inverter systems.
For engineers reviewing the TMX5701227AZWTQQ1 datasheet, TMX5701227AZWTQQ1 pinout, TMX5701227AZWTQQ1 application, or TMX5701227AZWTQQ1 equivalent, key selection criteria include ASIL-D compliance support, dual-CPU lockstep architecture, N2HET timing coprocessor count, ePWM channel availability, and ZWT 337-ball BGA package compatibility.
Technical Context
The TMX5701227AZWTQQ1 implements a dual-core lockstep execution model where both Cortex-R4F CPUs execute identical instructions and compare results in real time to detect transient faults. Its safety architecture includes on-chip BIST for CPU and RAM, ECC on flash and SRAM, parity on peripheral memories, and dedicated Error Signaling Module (ESM) with nERROR output.
It integrates two Next Generation High-End Timer (N2HET) modules - N2HET1 with 32 programmable channels and N2HET2 with 18 channels - each featuring hardware angle generation, HTU-based DMA transfers, and MPU-protected memory access. The device supports IEEE 802.3-compliant Ethernet MAC (MII/RMII/MDIO), FlexRay v2.1 (dual-channel), and three DCAN controllers compliant with CAN 2.0A/B up to 1 Mbps.
