STR731FV2T6STR731FV2T6 Overview
The STR731FV2T6 is a 32-bit ARM7TDMI microcontroller from STMicroelectronics' STR7 family, the generation of ARM parts ST shipped before the STM32 era. It runs at 36 MHz with 256KB of flash and 16KB of RAM, integrates CAN alongside UART/USART, I2C and SPI interfaces, a 12-bit 10-channel ADC, PWM, DMA and a watchdog, and offers 72 I/O lines in an LQFP100 package (14 mm x 14 mm). Its most distinctive trait today is the supply range: 4.5 V to 5.5 V, a genuine 5 V ARM microcontroller, which is exactly why so many industrial systems designed around it are still in the field.
The part is specified for -40 °C to +85 °C operation. Per ST's datasheet the STR731F variants carry 3 CAN and 4 UART channels, which made the family a natural controller for industrial networking and machine control in the mid-2000s.
Obsolete at ST, alive in the field
STMicroelectronics has discontinued the STR7 family: the STR731FV2T6 is obsolete and no longer manufactured, and franchised distributors show zero stock. The catch for the machines still running it is that there is no drop-in successor. Catalog cross-references point to STM32 parts, but those are 3.3 V devices with different pinouts and a different core generation, so a swap means a board redesign, a firmware port and requalification. For equipment with years of service life left, sustaining the original part is usually the economical route. Our guides to sourcing obsolete electronic components and last time buy strategy walk through exactly this decision.
For teams that do choose the redesign path, ST's modern line is well supported: GlobX also stocks current STM32 parts such as the STM32H743VIT6 for new designs, while keeping the legacy silicon flowing for the installed base.
Typical applications
- Industrial automation controllers and CAN-networked machine control designed in the 2000s
- 5 V industrial systems where the logic rails rule out modern 3.3 V MCUs without a redesign
- Building infrastructure, energy and transport equipment with decades-long service lives
- Repair, refurbishment and sustaining production of fielded STR7-based boards
Key specifications
- Core: 32-bit ARM7TDMI, 36 MHz

- Status: Obsolete - no longer manufactured by ST; zero franchised stock
Because the STR731FV2T6 is obsolete and no longer in production, genuine stock is finite and counterfeits cluster around exactly this kind of part: an out-of-production MCU that fielded equipment cannot run without. GlobX currently records 5,000 pieces, sourced through a verified global supplier network with ISO 9001 incoming inspection, anti-counterfeit checks, full traceability and a certificate of conformance on request. Request a quote with your quantity and date-code requirements and we will respond within 24 hours.
Why GlobX Is the Better Source for the STR731FV2T6
GlobX is an independent electronic-components distributor based in Europe with 12+ years of sourcing experience in arm microcontrollers - mcu. For STMicroelectronics parts like the STR731FV2T6, that means verified supply even when franchised channels quote long lead times or allocation.
- Real stock, not a listing: 5,000 units of the STR731FV2T6 are physically available for immediate quotation and dispatch.
- Traceability and quality screening: ISO 9001-qualified suppliers, full lot traceability, and counterfeit-risk inspection on every shipment.
- European logistics: fast delivery across the EU with customs and compliance handled, from our base in Germany.
- Shortage and EOL expertise: we specialise in allocation, hard-to-find and end-of-life components, so one RFQ also surfaces vetted alternatives when the STR731FV2T6 is constrained.
- One accountable partner: 500+ OEM and EMS customers, 98% satisfaction, and a named contact instead of an anonymous marketplace.

FAQs
Frequently Asked Questions about STR731FV2T6by STMicroelectronics
What is STR731FV2T6?
STR731FV2T6 is a 32-bit ARM7TDMI microcontroller from STMicroelectronics' STR7 family, the ARM generation ST produced before the STM32 line. It runs at 36 MHz with 256KB of flash and 16KB of RAM, integrates CAN, UART, I2C and SPI interfaces plus a 12-bit 10-channel ADC, and operates from a 4.5 V to 5.5 V supply in an LQFP100 package. It was widely designed into industrial and CAN-networked control systems in the 2000s.
What are the key specifications of STR731FV2T6?
The STR731FV2T6 combines a 36 MHz ARM7TDMI core with 256KB of flash and 16KB of RAM. Per ST's datasheet the STR731F variants provide 3 CAN and 4 UART channels alongside I2C and SPI, a 12-bit ADC with 10 channels, PWM, DMA and a watchdog, across 72 I/O lines. The supply range is 4.5 V to 5.5 V, the package is LQFP100 measuring 14 mm by 14 mm, and the operating range is -40 C to +85 C.
Is STR731FV2T6 obsolete?
Yes. STMicroelectronics has discontinued the STR7 family, and the STR731FV2T6 is listed as obsolete and no longer manufactured, with zero stock in franchised distribution. The silicon remains widely deployed in industrial equipment, so demand continues from maintenance and sustaining production. Remaining genuine stock is finite, which is why teams supporting fielded STR7 designs secure verified inventory ahead of need.
What is the replacement for STR731FV2T6?
There is no drop-in replacement. Catalog cross-references point to STM32 microcontrollers, but those are 3.3 V devices with different pinouts, peripherals and a newer core, so moving to one means a board redesign, a firmware port and requalification. The STR731FV2T6's 5 V supply range in particular ties it into systems that cannot casually switch to 3.3 V logic. For equipment with remaining service life, sourcing the original part is usually more economical than redesigning; for new designs, the modern STM32 line is the natural successor.
Why do industrial systems still use a 5 V ARM microcontroller?
Industrial electronics standardised on 5 V logic for decades because of its noise margins and installed infrastructure, and machines built around 5 V rails, sensors and level conventions stay in service for twenty years or more. The STR731FV2T6 is one of the few ARM-class controllers that runs natively from 4.5 V to 5.5 V, so it slotted into those systems without level shifting. That same trait now makes migration expensive, which keeps demand for the original part alive years after its discontinuation.
Is STR731FV2T6 available at GlobX?
Yes. GlobX currently records 5,000 pieces of the STR731FV2T6, sourced through a verified global supplier network with ISO 9001 incoming inspection, anti-counterfeit checks and full traceability, plus a certificate of conformance on request. Verification matters doubly for an obsolete MCU, because out-of-production parts that fielded equipment depends on are prime targets for counterfeiting. Quotes are returned within 24 hours.
