Overview
TMS5702124CPGEQQ1 from Texas Instruments is an automotive-grade 32-bit ARM Cortex-R4F safety microcontroller with dual-lockstep CPUs, 2MB flash with ECC, 192KB RAM with ECC, and integrated safety features including BIST, parity-protected peripherals, and error signaling. It delivers 298 DMIPS at 180 MHz and targets brake control, electric power steering, and battery management systems.
For engineers reviewing the TMS5702124CPGEQQ1 datasheet, TMS5702124CPGEQQ1 pinout, TMS5702124CPGEQQ1 application, or TMS5702124CPGEQQ1 equivalent, key selection criteria include ASIL-D compliance support, dual-CPU lockstep architecture, N2HET timer channel count, CAN/LIN/SCI interface availability, and PGE package pin compatibility for automotive ECU designs.
Technical Context
The TMS5702124CPGEQQ1 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 subsystem includes built-in self-test (BIST) for CPU and SRAM, ECC on flash and RAM, and parity protection across MibADC buffers, N2HET RAM, and DMA control packets.
It integrates two Next Generation High-End Timer (N2HET) modules-N2HET1 with 32 programmable channels and N2HET2 with 18 channels-each backed by dedicated HTU and MPU for safe DMA transfers. The device supports three DCAN controllers compliant with CAN 2.0B up to 1 Mbps, one LIN 2.1 interface, two 12-bit MibADCs (24 total channels), and three MibSPIs with up to 6 chip selects each.

FAQ
What safety certifications does the TMS5702124CPGEQQ1 support?
The TMS5702124CPGEQQ1 supports ISO 26262 ASIL-D development flow with hardware safety mechanisms including dual-lockstep CPUs, ECC on flash and RAM, parity on peripheral memories, BIST, and error signaling. Texas Instruments provides safety manuals, FMEDA reports, and diagnostic software libraries to enable customer certification. TMS5702124CPGEQQ1 is AEC-Q100 Grade 1 qualified and designed for automotive safety applications requiring highest integrity level.
Does the TMS5702124CPGEQQ1 include an external memory interface?
No, the TMS5702124CPGEQQ1 does not include an External Memory Interface (EMIF). Unlike the TMS570LS3134 variant, this device omits EMIF to reduce cost and complexity for applications that rely solely on on-chip memory. All code and data execution occurs from its 2MB flash and 192KB RAM. TMS5702124CPGEQQ1 retains full peripheral complement-including three DCAN, two N2HET, and dual MibADC-within the PGE package footprint.
What is the maximum operating frequency of the TMS5702124CPGEQQ1?
The TMS5702124CPGEQQ1 operates at a maximum system clock frequency of 180 MHz, delivering up to 298 DMIPS performance. This frequency is achieved using the Frequency-Modulated Phase-Locked Loop (FMPLL) to multiply the external crystal reference. The core supply (VCC) must be maintained between 1.14 V and 1.32 V, and the I/O supply (VCCIO) between 3.0 V and 3.6 V for stable operation at this speed. TMS5702124CPGEQQ1 maintains full ASIL-D safety features at rated frequency.
How many CAN interfaces does the TMS5702124CPGEQQ1 support?
The TMS5702124CPGEQQ1 supports three Controller Area Network (DCAN) interfaces compliant with CAN 2.0B protocol, each capable of bit rates up to 1 Mbps. These controllers operate independently with dedicated message RAM (64 mailboxes total), parity protection, and loopback test modes. They are intended for distributed automotive networking in safety-critical domains such as chassis, powertrain, and body control. TMS5702124CPGEQQ1 does not support CAN FD.
Is the TMS5702124CPGEQQ1 pin-compatible with other TMS570 devices in the PGE package?
Yes, the TMS5702124CPGEQQ1 is pin-compatible with TMS570LS2134PGE and TMS570LS3134PGE within the LQFP-144 (PGE) package. All share identical ball/pin mapping, power domains, and peripheral I/O assignments. Differences lie in internal memory size (192KB vs. 256KB RAM) and flash configuration (2MB only), which do not affect PCB layout. Firmware may require minor linker script updates, but hardware design remains unchanged across these PGE variants. TMS5702124CPGEQQ1 maintains full functional compatibility for drop-in replacement in existing PGE-based designs.
