Product details
Overview
TMS5701114BPGEQQ1 from Texas Instruments is an automotive-grade 32-bit RISC flash microcontroller featuring dual ARM Cortex-R4F CPUs in lockstep, 1 MB flash with ECC, 128 KB RAM with ECC, and integrated safety mechanisms including BIST, voltage/clock monitoring, and error signaling. It delivers 298 DMIPS at 180 MHz and supports real-time motor control via seven ePWM modules, six eCAP modules, two eQEP modules, and two 12-bit MibADCs with 24 total inputs.
For engineers reviewing the TMS5701114BPGEQQ1 datasheet, TMS5701114BPGEQQ1 pinout, TMS5701114BPGEQQ1 application, or TMS5701114BPGEQQ1 equivalent, key selection criteria include ASIL-D compliance support, dual-CPU lockstep architecture, N2HET timing coprocessor capability, CAN 2.0B interface count, and 144-pin LQFP (PGE) package compatibility for safety-critical automotive control designs.
Technical Context
The TMS5701114BPGEQQ1 implements a dual-core lockstep execution model where both Cortex-R4F CPUs execute identical instructions and compare results in real time to detect transient or permanent faults. Its safety infrastructure includes on-chip BIST for CPU and SRAM, ECC protection across flash and RAM, parity on peripheral memories, and dedicated Error Signaling Module (ESM) with nERROR output pin.
Real-time control is enabled by two Next Generation High-End Timer (N2HET) modules - N2HET1 with 32 programmable channels and N2HET2 with 18 channels - each paired with a hardware angle generator and dedicated HTU for DMA-style data transfers. The device integrates three DCAN controllers compliant with CAN 2.0A/B, supporting up to 1 Mbps in harsh automotive environments.

FAQ
What safety certifications does the TMS5701114BPGEQQ1 support?
The TMS5701114BPGEQQ1 is architected to support ISO 26262 ASIL-D compliance through hardware features including dual Cortex-R4F CPUs in lockstep, on-chip BIST for CPU and RAM, ECC on flash and SRAM, parity on peripheral memories, and dedicated Error Signaling Module (ESM). These capabilities form the foundation for certified safety software stacks - the TMS5701114BPGEQQ1 itself is not pre-certified, but its safety mechanisms are documented in TI's Functional Safety Documentation Package (FSDP) for use in certified systems.
Does the TMS5701114BPGEQQ1 include CAN FD support?
No, the TMS5701114BPGEQQ1 includes three DCAN controllers compliant only with CAN 2.0A and 2.0B protocols, supporting data rates up to 1 Mbps. It does not implement CAN FD features such as flexible data-rate arbitration or extended payload length. For CAN FD requirements, designers should consider newer Hercules™ devices like the TMS570LC4357 or migrate to TI's AM263x real-time MCUs.
What is the maximum operating frequency of the TMS5701114BPGEQQ1?
The TMS5701114BPGEQQ1 operates at a maximum system clock frequency of 180 MHz, delivering up to 298 DMIPS performance. This frequency applies to both lockstep CPUs and is sustained across the full automotive temperature range (–40°C to 125°C) under specified VCC (1.14–1.32 V) and VCCIO (3.0–3.6 V) conditions per the SPNS188B datasheet.
How many N2HET channels does the TMS5701114BPGEQQ1 provide?
The TMS5701114BPGEQQ1 integrates two Next Generation High-End Timer (N2HET) modules: N2HET1 with 32 programmable channels and N2HET2 with 18 channels, totaling 50 channels. However, due to pin multiplexing constraints in the 144-pin PGE package, only 40 N2HET I/O terminals are accessible - matching the device's documented N2HET channel count for this variant.
Is external memory supported by the TMS5701114BPGEQQ1?
Yes, the TMS5701114BPGEQQ1 includes a 16-bit External Memory Interface (EMIF) supporting asynchronous SRAM, EPROM, and NOR flash devices. It provides EMIF_ADDR[12:0], EMIF_DATA[15:0], EMIF_nCS[4:2], EMIF_nOE, EMIF_nWE, EMIF_nRAS, EMIF_nCAS, and EMIF_CLK signals - enabling up to 32 KB addressable space for external memory expansion in safety-critical applications.
