Product details
Overview
TMS5701114CPGEQQ1 from Texas Instruments is an automotive-grade 32-bit RISC flash microcontroller with dual lockstep ARM Cortex-R4F CPUs, 1 MB ECC-protected flash, 128 KB ECC RAM, and integrated safety features including BIST, voltage/clock monitoring, and error signaling - deployed in electric power steering and ABS systems.
For engineers reviewing the TMS5701114CPGEQQ1 datasheet, TMS5701114CPGEQQ1 pinout, TMS5701114CPGEQQ1 application, or TMS5701114CPGEQQ1 equivalent, key selection criteria include ASIL-D compliance support, dual-CPU lockstep execution integrity, N2HET timing coprocessor count, ePWM channel availability, and 144-pin LQFP (PGE) package compatibility with automotive PCB layouts.
Technical Context
The TMS5701114CPGEQQ1 implements a safety-critical architecture with two identical ARM Cortex-R4F cores executing identical instructions in lockstep, continuously comparing results to detect transient or permanent faults. Its FMPLL and nonmodulating PLL provide independent clock domains for core, peripheral, and real-time control subsystems.
Real-time peripherals include two N2HET modules (N2HET1 with 32 channels, N2HET2 with 18 channels), seven ePWM modules (14 outputs total), six eCAP modules, two eQEP modules, and dual 12-bit MibADCs supporting up to 24 shared analog inputs - all accessible via dedicated HTU DMA paths with MPU protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS570LS1227ZWT | 337-ball BGA, 180 MHz CPU, 1280 KB flash, 192 KB RAM, adds FlexRay and EMAC - larger footprint and higher cost. | Targeted at full-vehicle domain controllers requiring Ethernet/FlexRay backbone integration. | Select when needing automotive Ethernet connectivity or additional RAM for multi-threaded diagnostics stack. |
| TMS570LS0714PGE | Same 144-pin PGE package, 160 MHz CPU, 768 KB flash, 128 KB RAM, retains 3 DCAN and dual N2HET - reduced flash capacity only. | Suitable for cost-optimized EPS or ABS variants where firmware size is constrained to <768 KB. | Choose for legacy design migration or BOM cost reduction where full 1 MB flash is unused. |
Compared with TMS5701114CPGEQQ1, the TMS570LS1227ZWT offers expanded connectivity at the expense of package compatibility and cost, while the TMS570LS0714PGE maintains pinout and safety architecture but trades flash capacity for lower unit price - both require validation of functional safety documentation alignment.

FAQ
What safety certifications apply to the TMS5701114CPGEQQ1?
The TMS5701114CPGEQQ1 is qualified for automotive applications per AEC-Q100 Grade 1 and supports ISO 26262 ASIL-D system-level development. It includes built-in self-test (BIST), lockstep CPU comparison, ECC memory, and error signaling - all documented in TI's Functional Safety Manual SPNU513. The TMS5701114CPGEQQ1 device itself does not carry third-party certification, but its architecture enables certified system designs.
Does the TMS5701114CPGEQQ1 support CAN FD?
No, the TMS5701114CPGEQQ1 integrates three DCAN controllers compliant only with CAN 2.0A and 2.0B protocols, with a maximum bit rate of 1 Mbps. It does not implement CAN FD framing, arbitration, or data-rate switching capabilities. For CAN FD support, TI's RM4x or newer TMS570 variants must be considered - the TMS5701114CPGEQQ1 is strictly legacy CAN-compatible.
What is the maximum operating frequency of the TMS5701114CPGEQQ1?
The TMS5701114CPGEQQ1 operates at up to 160 MHz system clock frequency, as specified in Section 5.4 of the SPNS188B datasheet. This is lower than the 180 MHz capability of ZWT-package variants due to thermal and signal-integrity constraints of the 144-pin PGE package - confirmed by TI's device comparison table and recommended operating conditions.
Can the TMS5701114CPGEQQ1 execute code from external memory?
No, the TMS5701114CPGEQQ1 lacks an external memory interface (EMIF) in the PGE package variant - Table 1-1 and Section 6.14 confirm EMIF is only available on ZWT BGA packages. Code execution is restricted to on-chip 1 MB flash and 128 KB RAM; external memory access is not supported for program fetch or data storage on this specific part.
How many ADC input channels does the TMS5701114CPGEQQ1 support?
The TMS5701114CPGEQQ1 integrates two 12-bit MibADC modules supporting up to 24 total analog inputs - with 16 channels shared between ADC1 and ADC2, and 8 dedicated to ADC1. This configuration is identical across all TMS570LS1114 variants, including the PGE package, and is validated in Section 1.3 and Table 3-1 of the datasheet.
