Product details
Overview
TMS5702134DPGEQQ1 from Texas Instruments is a safety-certified 32-bit ARM Cortex-R4F microcontroller for automotive ASIL-D and IEC 61508 SIL-3 applications, featuring dual lockstep CPUs, 2MB flash with ECC, 256KB RAM with ECC, three DCAN controllers, two 12-bit MibADCs (24-channel total), and two N2HET timing coprocessors (32+18 channels). It operates at up to 180 MHz with 1.2 V core and 3.3 V I/O supply.
For engineers reviewing the TMS5702134DPGEQQ1 datasheet, TMS5702134DPGEQQ1 pinout, TMS5702134DPGEQQ1 application, or TMS5702134DPGEQQ1 equivalent, key selection criteria include ASIL-D compliance, integrated BIST and error signaling, FMPLL clocking with slip detection, EMIF support, and trace/debug capabilities including ETM-R4 and RTP.
Technical Context
The TMS5702134DPGEQQ1 implements a dual-CPU lockstep architecture with hardware BIST for CPU and SRAM, ECC on flash and RAM, parity on peripheral memories, and loopback-capable I/O for fault containment. Its safety subsystem includes an Error Signaling Module (ESM) that drives the dedicated nERROR pin upon detected faults.
It integrates two independent N2HET modules - N2HET1 with 32 programmable channels and N2HET2 with 18 - each backed by a dedicated HTU with MPU protection and hardware angle generation. The device supports real-time deterministic control via MibADC group sequencing, vectored interrupts (96-channel VIM), and DMA with 16 channels and 32 peripheral requests.

FAQ
What safety certifications does the TMS5702134DPGEQQ1 support?
The TMS5702134DPGEQQ1 is certified for ASIL-D per ISO 26262 and SIL-3 per IEC 61508. Its dual lockstep CPU, ECC memory, BIST, ESM, and parity-protected peripherals meet the diagnostic coverage and fault containment requirements of these standards. TI provides safety manuals, FMEDA reports, and safety analysis documentation specifically for the TMS5702134DPGEQQ1.
Does the TMS5702134DPGEQQ1 support external memory expansion?
Yes, the TMS5702134DPGEQQ1 includes a 16-bit External Memory Interface (EMIF) supporting synchronous DRAM (SDRAM), asynchronous memories, FPGAs, and peripherals. It provides EMIF_CLK, EMIF_nCS, EMIF_ADDR[21:0], EMIF_DATA[15:0], and control signals - fully documented in Section 6.14 of the SPNS165B datasheet for the TMS5702134DPGEQQ1.
What is the role of the nERROR pin on the TMS5702134DPGEQQ1?
The nERROR pin on the TMS5702134DPGEQQ1 is an active-low, open-drain output driven by the Error Signaling Module (ESM). It asserts when CPU, memory, clock, or peripheral faults are detected - serving as a system-level fail-safe indicator. External circuitry can use this signal to trigger watchdog resets, disable power stages, or illuminate warning lamps without software intervention.
Can the TMS5702134DPGEQQ1 operate without an external crystal?
No - the TMS5702134DPGEQQ1 requires an external crystal or oscillator connected to the X1/X2 pins to drive its main oscillator (MOSC). The FMPLL then multiplies this reference to generate internal clocks. While the device includes a low-frequency internal RC oscillator for wake-up, it lacks sufficient accuracy and stability for full operation or safety-critical timing - making external crystal mandatory for TMS5702134DPGEQQ1 deployment.
How many CAN interfaces does the TMS5702134DPGEQQ1 integrate?
The TMS5702134DPGEQQ1 integrates three fully compliant DCAN controllers supporting CAN 2.0B protocol at up to 1 Mbps. Each controller has 64 mailboxes with parity protection, shared message RAM, and dedicated transmit/receive pins - enabling redundant vehicle networks or multi-domain communication (e.g., powertrain, chassis, body) within a single TMS5702134DPGEQQ1 device.
