Product details
Overview
V62/18606-01XF from Texas Instruments is a radiation-tolerant, high-integrity automotive-grade ARM® Cortex®-R5F dual-core microcontroller designed for safety-critical aerospace and defense systems. It integrates 4MB ECC-protected flash, 512KB ECC-protected RAM, dual-lockstep CPUs operating up to 300 MHz, and supports ISO 26262 ASIL-D and IEC 61508 SIL-3 compliance. It is deployed in flight control computers and satellite power management units requiring fault detection, self-test, and error signaling.
For engineers reviewing the V62/18606-01XF datasheet, V62/18606-01XF pinout, V62/18606-01XF application, or V62/18606-01XF equivalent, key selection criteria include lockstep CPU architecture, ECC coverage across memory and peripherals, extended temperature range (–55°C to 125°C), EMIF support for external memory expansion, and integrated safety modules including ESM, BIST, and FMPLL with slip detection.
Technical Context
The V62/18606-01XF implements two ARM Cortex-R5F cores executing in hardware-enforced lockstep with 32KB I-cache and 32KB D-cache, both protected by ECC. Its safety architecture includes dedicated Error Signaling Module (ESM) with nERROR output, Built-In Self-Test (BIST) for CPU and N2HET coprocessors, and voltage/clock monitoring circuits.
Peripherals are safety-architected: dual VIM interrupt controllers operate in lockstep mode with ECC-protected vector tables; two CRC modules verify data integrity; DMA controller features ECC-protected control RAM and MPU protection; and all four DCAN modules comply with CAN 2.0B at up to 1 Mbps with 64 ECC-protected mailboxes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar safety-critical microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

What is the qualified temperature range for V62/18606-01XF?
V62/18606-01XF is qualified for operation from –55°C to +125°C ambient temperature. This extended range is achieved through controlled baseline manufacturing, single assembly/test site, and rigorous screening-making it suitable for defense, aerospace, and downhole industrial applications where commercial-grade MCUs would fail.
Does V62/18606-01XF support JTAG debugging and trace?
Yes, V62/18606-01XF includes IEEE 1149.1 JTAG boundary scan, ARM CoreSight debug infrastructure, ETM instruction/data trace, RTP for RAM/peripheral access tracing, and DMM for external memory writes-all accessible via standard debug probes. These capabilities are fully supported in TI's Code Composer Studio and third-party tools for safety-critical validation.
How does the Error Signaling Module (ESM) function in V62/18606-01XF?
The ESM in V62/18606-01XF continuously monitors internal fault conditions-including ECC double-bit errors, clock failures, and voltage monitor violations-and asserts the dedicated nERROR pin to signal external systems. It operates independently of CPU firmware, enabling fail-safe shutdown or safe state entry even if software is compromised.
Can V62/18606-01XF interface with external SDRAM or NOR flash?
Yes, V62/18606-01XF includes a 16-bit External Memory Interface (EMIF) supporting asynchronous and synchronous memories including SDRAM, SRAM, and NOR flash. The EMIF provides configurable wait states, address/data multiplexing, and dedicated control signals (nRAS, nCAS, nWE) for direct connection without glue logic.
What safety certifications apply to V62/18606-01XF?
V62/18606-01XF is designed to support ISO 26262 ASIL-D and IEC 61508 SIL-3 system-level certification.
