Key Parameters

Substitute Part Grouping Explanation

Substitution of the XC2S30-5CS144I is determined by the following critical parameters:

Functional Compatibility Criteria:

• Number of I/O pins: 92 (minimum requirement)
• Logic capacity: 972 logic elements/cells (minimum requirement)
• RAM capacity: 24,576 bits (minimum requirement)
• Operating temperature range: -40°C ~ 100°C (TJ)
• Mounting type: Surface Mount
• Package pin count: 144 pins

Electrical Compatibility Criteria:

• Supply voltage operating range must accommodate system requirements
• MSL rating: 3 (168 Hours)

The substitute part T8Q144I4 (Efinix Trion® FPGA) meets functional compatibility through equivalent I/O count (97 pins), superior logic capacity (7,384 cells), and greater RAM capacity (125,829 bits). Both devices operate across the -40°C ~ 100°C temperature range and feature 144-pin surface mount packages. The T8Q144I4 operates at a lower supply voltage (1.15V ~ 1.25V) and maintains MSL 3 rating, making it suitable for applications where the XC2S30-5CS144I is no longer available.

Parameter Comparison

Engineering Selection Recommendations

XC2S30-5CS144I (Main Part): Use for existing designs currently in production or maintenance phase. This device is Last Time Buy status with 2,140 units in stock. RoHS non-compliant status restricts use in new designs subject to RoHS regulations. Suitable only for legacy system support and end-of-life inventory management.

T8Q144I4 (Substitute Part): Use for new designs and design transitions. This device is Active status with 53,271 units in stock, ensuring long-term availability. ROHS3 compliance satisfies regulatory requirements for new product development. The Trion® architecture provides superior logic capacity (7,384 cells vs. 972 cells) and RAM capacity (125,829 bits vs. 24,576 bits), offering design headroom for future feature expansion. Lower supply voltage (1.15V ~ 1.25V) reduces power consumption compared to the XC2S30-5CS144I (2.375V ~ 2.625V). Package transition from 144-TFBGA/CSPBGA to 144-LQFP requires PCB layout redesign.

Frequently Asked Questions (FAQ)

Q: Can the T8Q144I4 directly replace the XC2S30-5CS144I in existing designs?

A: Direct pin-for-pin replacement is not possible. The XC2S30-5CS144I uses 144-TFBGA/CSPBGA packaging, while the T8Q144I4 uses 144-LQFP packaging. Both packages have 144 pins but different physical dimensions, pin pitch, and PCB footprints. PCB redesign is required for substitution.

Q: What are the I/O compatibility considerations?

A: The XC2S30-5CS144I provides 92 I/O pins, while the T8Q144I4 provides 97 I/O pins. The substitute part offers additional I/O capacity. Pin assignment and signal routing must be verified against the respective device datasheets to ensure functional compatibility with system requirements.

Q: How does the supply voltage difference affect substitution?

A: The XC2S30-5CS144I operates at 2.375V ~ 2.625V, while the T8Q144I4 operates at 1.15V ~ 1.25V. System power delivery architecture must be redesigned to accommodate the lower voltage requirement of the substitute part. This change reduces power consumption but requires new voltage regulation circuitry.

Q: Are there any compliance differences between these parts?

A: The XC2S30-5CS144I is RoHS non-compliant, while the T8Q144I4 is ROHS3 compliant. For applications subject to RoHS regulations, the T8Q144I4 is the only acceptable option. Both parts maintain MSL 3 (168 Hours) moisture sensitivity rating.

Q: What is the logic capacity difference between these devices?

A: The XC2S30-5CS144I contains 972 logic elements, while the T8Q144I4 contains 7,384 logic elements. The substitute part provides approximately 7.6 times greater logic capacity, enabling more complex designs or future feature additions without requiring additional devices.

Q: What is the RAM capacity difference?

A: The XC2S30-5CS144I provides 24,576 RAM bits, while the T8Q144I4 provides 125,829 RAM bits. The substitute part offers approximately 5.1 times greater embedded memory capacity, supporting larger data buffers and more complex algorithmic implementations.

Q: What is the product status significance?

A: The XC2S30-5CS144I is Last Time Buy, indicating AMD has discontinued this product and will not accept new orders after a specified date. The T8Q144I4 is Active, meaning Efinix continues manufacturing and supporting this product for new designs. Active status ensures long-term availability and technical support.
