Product details
Overview
TMS5701114BZWTQQ1 from Texas Instruments is an automotive-grade 32-bit ARM Cortex-R4F safety microcontroller with dual-lockstep CPUs, 1MB ECC-protected flash, 128KB ECC RAM, and integrated real-time peripherals including two N2HET timers (44 I/O), seven ePWM modules, six eCAP, two eQEP, and dual 12-bit MibADCs - deployed in electric power steering and ABS systems.
For engineers reviewing the TMS5701114BZWTQQ1 datasheet, TMS5701114BZWTQQ1 pinout, TMS5701114BZWTQQ1 application, or TMS5701114BZWTQQ1 equivalent, key selection criteria include ASIL-D compliance support, FMPLL clocking with slip detection, DCAN 2.0B interface count, N2HET channel allocation, and ZWT BGA package thermal performance for under-hood automotive control units.
Technical Context
The TMS5701114BZWTQQ1 implements a dual-core lockstep execution architecture with built-in BIST, ECC on flash and SRAM, parity on peripheral memories, and error signaling via dedicated nERROR pin - enabling ISO 26262 ASIL-D system certification. Its FMPLL provides frequency-modulated clock synthesis with slip detection, while the Global Clock Module routes clocks across CPU, peripheral, and memory domains.
Real-time control is enabled by two independent N2HET coprocessors (N2HET1: 32 channels; N2HET2: 18 channels), each with hardware angle generator and HTU-based DMA transfers to main memory, plus ePWM modules supporting deadband generation, trip-zone protection, and MibADC synchronization - all managed under a unified 12-region MPU.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-R4F, 1.66 DMIPS/MHz, up to 180 MHz → delivers 298 DMIPS deterministic performance for safety-critical motor control loops. |

Pinout & Package
Package: 337-ball NFBGA (ZWT), 16.0 mm × 16.0 mm, 0.8 mm pitch, green RoHS-compliant. Ball map defined per TI SPNS188B Section 4.2; includes dedicated GIO, N2HET, ePWM, CAN, ADC, and debug pins with configurable pull-up/down and slew-rate control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| nERROR | Error signaling output | Active-low open-drain fault indicator tied to external watchdog or system supervisor - asserts on uncorrectable ECC, BIST failure, or clock monitor violation. |
| CAN1_RX / CAN1_TX | CAN controller interface | Differential bus transceiver pins compliant with ISO 11898-1; support 1 Mbps operation with internal termination options and loopback test mode. |

Key Features
| Feature | Design Value |
|---|---|
| Dual-lockstep Cortex-R4F CPUs | Hardware-enforced instruction-level redundancy with automatic fault detection and fail-safe response - foundational for ASIL-D decomposition. |
| FMPLL with slip detection | Frequency-modulated PLL monitors reference clock stability in real time; triggers error signaling if deviation exceeds ±0.5% - critical for fail-operational clocking. |
| N2HET + HTU co-processing | Offloads timing-critical tasks (e.g., encoder interpolation, PWM modulation) from CPU; HTU enables zero-CPU DMA transfers between N2HET RAM and main memory. |
| ePWM with trip-zone protection | Hardware-based fault reaction: immediate PWM shutdown on overcurrent, overtemperature, or external nTZ assertion - prevents IGBT shoot-through in inverters. |
| Parameter Overlay Module (POM) | Redirects flash reads to RAM or EMIF during runtime - enables field calibration updates without flash reprogramming or system reset. |

What safety certifications does the TMS5701114BZWTQQ1 support?
The TMS5701114BZWTQQ1 is architected to support ISO 26262 ASIL-D compliance through dual-lockstep Cortex-R4F CPUs, ECC on flash and RAM, BIST for CPU and memory, parity on peripheral RAM, and dedicated error signaling via the nERROR pin. TI provides certified safety manuals, FMEDA reports, and diagnostic software libraries to accelerate ASIL-D system development - all validated for use with the TMS5701114BZWTQQ1 in production automotive ECUs.
Does the TMS5701114BZWTQQ1 include CAN FD capability?
No, the TMS5701114BZWTQQ1 integrates three DCAN controllers compliant only with CAN 2.0A and 2.0B protocols (up to 1 Mbps), not CAN FD. It lacks the bit-rate switching, flexible data-length, and CRC enhancements defined in ISO 11898-1:2015. For CAN FD applications, engineers should consider newer TI devices such as the TC3xx series or evaluate external CAN FD transceivers with protocol translation - the TMS5701114BZWTQQ1 itself does not support CAN FD frame formatting or arbitration.
What is the maximum operating frequency of the TMS5701114BZWTQQ1?
The TMS5701114BZWTQQ1 operates at up to 180 MHz system clock frequency, delivering 298 DMIPS performance. This maximum frequency is achievable under specified conditions: core supply (VCC) 1.14–1.32 V, I/O supply (VCCIO) 3.0–3.6 V, and ambient temperature ≤105°C. The FMPLL and Global Clock Module manage clock distribution, and the device includes voltage and clock monitoring to enforce safe operation within this range - all verified in the TMS5701114BZWTQQ1 production characterization data.
How many ADC channels does the TMS5701114BZWTQQ1 support?
The TMS5701114BZWTQQ1 features two independent 12-bit Multibuffered ADC (MibADC) modules: MibADC1 supports 24 analog inputs (AD1IN[0]–AD1IN[23]), and MibADC2 supports 16 inputs (AD2IN[0]–AD2IN[15]), with 16 channels shared between them. Each module includes 64-word result buffers with parity protection and supports grouped sequential conversion, continuous mode, and 10-bit compatibility mode - fully documented for the TMS5701114BZWTQQ1 in TI's SPNS188B datasheet Section 7.4.
Is the TMS5701114BZWTQQ1 pin-compatible with other TMS570LS1114 variants?
Yes, the TMS5701114BZWTQQ1 shares the same 337-ball ZWT NFBGA package and pinout as the TMS570LS1114ZWT, as confirmed in TI's SPNS188B datasheet Table 1-1 and Section 4.2 ball-map definition. All signal names, power/ground allocations, and peripheral mappings match identically - enabling direct substitution in existing ZWT-layout designs without PCB revision, provided thermal and decoupling design margins accommodate the QQ1 automotive qualification grade.
