Key Parameters

Substitute Part Grouping Explanation

Substitution of the FT903L-T is determined by strict equivalence across the following critical parameters:

• Core processor architecture (FT32)
• Core configuration (32-Bit Single-Core)
• Operating frequency (100MHz)
• Program memory capacity and type (256KB FLASH)
• RAM capacity (320K x 8)
• Supply voltage range (2.97V ~ 3.63V)
• I/O count (65 pins)
• Connectivity interfaces (I2C, SD, SPI, UART/USART, USB)
• Peripheral set (I2S, POR, PWM, WDT)
• Data converter specifications (A/D 7x10b; D/A 2x10b)
• Operating temperature range (-40°C ~ 85°C)
• Package type (100-LQFP 14x14)

The FT903L-C-T meets all these criteria and is identified as a direct substitute. The primary distinction between these parts is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The FT903L-C-T is the direct substitute for the FT903L-T. Both parts are manufactured by Bridgetek Pte Ltd. and share identical electrical and mechanical specifications across all functional parameters.

The FT903L-C-T is classified as Active product status, whereas the FT903L-T is Obsolete. Selection of the FT903L-C-T ensures access to current manufacturing support and supply chain continuity. Both parts maintain REACH Unaffected compliance status.

The distinction between these parts is limited to packaging format: the FT903L-T uses standard packaging while the FT903L-C-T is supplied in Tray packaging. This difference does not affect electrical performance, pin configuration, or functional capability.

Frequently Asked Questions (FAQ)

Q: Are FT903L-T and FT903L-C-T pin-compatible?

A: Yes. Both parts use the 100-LQFP (14x14) package with identical pin assignments, I/O count (65), and electrical characteristics.

Q: What is the difference between FT903L-T and FT903L-C-T?

A: The parts are electrically and functionally identical. The primary differences are product status (Obsolete vs. Active) and packaging format (Standard vs. Tray). The FT903L-C-T is the recommended selection for new designs and ongoing production.

Q: Can I use FT903L-C-T as a direct replacement in existing designs?

A: Yes. The FT903L-C-T is a direct substitute with no design modifications required. All electrical parameters, memory specifications, connectivity interfaces, and peripheral functions are identical.
