M2S005S-TQ144 Equivalent & Substitute Parts

Part Overview

The M2S005S-TQ144 is an ARM Cortex-M3 System On Chip (SOC) IC from Microchip Technology's SmartFusion2 FPGA product line. This embedded processor integrates a 166MHz ARM Cortex-M3 core with 5K logic modules, 128KB flash memory, and 64KB RAM in a 144-LQFP package. The device supports multiple connectivity protocols including CANbus, Ethernet, I2C, SPI, UART/USART, and USB.

The M2S005S-TQ144 is classified as obsolete. Equivalent substitute parts are available in active product status, making substitution necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution of the M2S005S-TQ144 is determined by strict equivalence across the following parameters:

Core processor architecture (ARM Cortex-M3)
Operating frequency (166MHz)
Memory configuration (128KB flash, 64KB RAM)
FPGA logic module count (5K)
Package type and pin count (144-LQFP with 84 I/O)
Operating temperature range (0°C ~ 85°C)
Connectivity interfaces (CANbus, Ethernet, I2C, SPI, UART/USART, USB)
Moisture sensitivity level (MSL 3)

All substitute parts listed maintain identical electrical and mechanical specifications. Variations in part numbering reflect packaging format (Tray vs. standard), RoHS compliance status, and product lifecycle stage. The base product number M2S005 remains constant across all equivalents.

Engineering Selection Recommendations

For designs currently using the obsolete M2S005S-TQ144, the following active alternatives are available:

Primary Substitutes (Full Electrical and Mechanical Equivalence):

M2S005S-TQG144: Active product status, ROHS3 compliant, highest inventory availability (2960 Pcs)
M2S005S-1TQG144: Active product status, ROHS3 compliant, Tray packaging (1079 Pcs)
M2S005-TQG144: Active product status, ROHS3 compliant, Tray packaging (972 Pcs)
M2S005-1TQG144: Active product status, ROHS3 compliant, Tray packaging (1030 Pcs)

All primary substitutes maintain identical core specifications: ARM Cortex-M3 at 166MHz, 128KB flash, 64KB RAM, 5K FPGA logic modules, 144-LQFP package with 84 I/O, and MSL 3 moisture sensitivity. All are ROHS3 compliant, addressing environmental compliance requirements not met by the obsolete original part.

Alternative with Modified I/O Configuration:

M2S005S-1TQG144T2: Active product status, 213 I/O count (differs from standard 84 I/O). This part is suitable only for designs requiring expanded I/O capability and is not a direct pin-for-pin substitute.

Selection should prioritize parts with active product status and ROHS3 compliance for new designs. Packaging format (Tray) is suitable for production environments. Inventory levels support immediate procurement across all primary substitutes.

Frequently Asked Questions (FAQ)

Q: Can M2S005S-TQG144 directly replace M2S005S-TQ144 in existing designs?

A: Yes. M2S005S-TQG144 is a direct electrical and mechanical equivalent. Both devices feature identical ARM Cortex-M3 core at 166MHz, 128KB flash, 64KB RAM, 5K FPGA logic modules, and 144-LQFP package with 84 I/O. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between M2S005-TQG144 and M2S005S-TQG144?

A: Both parts are parametrically equivalent with identical electrical specifications. The difference lies in part numbering convention within Microchip's product line. Both are active, ROHS3 compliant, and suitable for direct substitution.

Q: Is M2S005S-1TQG144T2 a suitable substitute?

A: M2S005S-1TQG144T2 maintains core processor, memory, and FPGA specifications identical to M2S005S-TQ144. However, it features 213 I/O instead of 84 I/O. This part is suitable only if your design requires expanded I/O capability and can accommodate the different pin configuration. It is not a pin-for-pin substitute.

Q: What does "Tray" packaging mean?

A: Tray packaging indicates the component is supplied in a plastic tray format suitable for automated assembly and production environments. This is standard for high-volume manufacturing. The electrical and mechanical specifications remain identical to non-tray variants.

Q: Why is RoHS compliance important for substitution?

A: RoHS3 compliance ensures the substitute part meets environmental and hazardous substance restrictions. The original M2S005S-TQ144 is RoHS non-compliant. All active substitutes are ROHS3 compliant, making them suitable for applications with environmental compliance requirements.

Q: Are all substitute parts from the same manufacturer?

A: Yes. All substitute parts are manufactured by Microchip Technology, ensuring consistent quality, reliability, and technical support.
