Product details
Overview
TMS5702125BPGEQQ1 from Texas Instruments is a safety-certified 32-bit ARM Cortex-R4F microcontroller with dual-core lockstep architecture, 2MB flash, 256KB RAM, and integrated diagnostics for ASIL-D automotive applications. It features a 180-MHz CPU, EMAC interface, multiple CAN FD controllers, and hardware-based memory protection.
For engineers reviewing the TMS5702125BPGEQQ1 datasheet, TMS5702125BPGEQQ1 pinout, TMS5702125BPGEQQ1 application, or TMS5702125BPGEQQ1 equivalent, key selection considerations include ASIL-D compliance, dual-core lockstep execution integrity, flash ECC coverage, built-in self-test (BIST) support, and CAN FD timing accuracy under voltage/temperature variation.
Technical Context
The TMS5702125BPGEQQ1 implements a dual-core lockstep (DCLS) execution model where both Cortex-R4F cores execute identical instructions in parallel with cycle-aligned comparison. Its VIM (Vector Interrupt Manager) supports 128 configurable interrupt channels with priority arbitration and latency control down to 12 cycles.
Memory subsystem includes 2MB of on-chip flash with single-bit error correction and double-bit error detection (SECDED), plus 256KB of SRAM with parity checking. The device integrates a dedicated Safety Manager (SVM) that monitors clock domain integrity, memory BIST status, and watchdog timer health.
