Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMS320F2802ZGMS is determined by the following critical parameters that must remain consistent:

• Core Processor Architecture: C28x processor family
• Core Configuration: 32-Bit Single-Core
• Operating Frequency: 100MHz
• Voltage Supply Range: 1.71V ~ 1.89V
• Data Converter Specification: A/D 16x12b
• Connectivity Interfaces: CANbus, I2C, SCI, SPI, UART/USART
• Peripheral Set: POR, PWM, WDT
• I/O Count: 35 pins
• Operating Temperature Range: -40°C ~ 125°C
• Package Type: 100-pin BGA form factor
• Compliance Standards: ROHS3, AEC-Q100

The TMS320F2806NMFS qualifies as a substitute based on matching all critical parameters. Variations in program memory size (64KB vs. 32KB) and RAM size (6K x 16 vs. 10K x 16) do not preclude substitution when application requirements permit reduced FLASH capacity with increased RAM availability.

Parameter Comparison

Engineering Selection Recommendations

The TMS320F2806NMFS is the designated substitute for the obsolete TMS320F2802ZGMS. Selection of this substitute is supported by the following factors:

Product Status: The TMS320F2806NMFS maintains Active product status, ensuring continued availability and manufacturer support, whereas the TMS320F2802ZGMS is Obsolete.

Compliance and Certification: Both devices maintain ROHS3 compliance and AEC-Q100 automotive qualification, preserving regulatory and quality requirements for automotive and industrial applications.

Functional Equivalence: The substitute maintains identical core processor architecture, operating frequency, voltage supply range, data converter specifications, connectivity interfaces, peripheral configuration, I/O count, and operating temperature range.

Memory Configuration: The TMS320F2806NMFS provides 32KB FLASH and 10K x 16 RAM compared to the original 64KB FLASH and 6K x 16 RAM. Applications requiring FLASH capacity exceeding 32KB or RAM capacity below 10K x 16 require alternative evaluation.

Package Compatibility: Both devices utilize 100-pin BGA packaging with identical pinout and electrical characteristics, enabling direct PCB-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the TMS320F2806NMFS directly replace the TMS320F2802ZGMS in existing designs?

A: Yes, for applications where program memory requirements do not exceed 32KB and RAM requirements do not exceed 10K x 16. The identical core processor, operating frequency, voltage supply, connectivity, peripherals, I/O count, temperature range, and 100-pin BGA package enable direct substitution at the PCB level.

Q: What are the memory differences between these parts?

A: The TMS320F2802ZGMS provides 64KB FLASH and 6K x 16 RAM. The TMS320F2806NMFS provides 32KB FLASH and 10K x 16 RAM. Applications must confirm that reduced FLASH capacity and increased RAM capacity are compatible with firmware and data storage requirements.

Q: Are both devices qualified for automotive applications?

A: Yes. Both the TMS320F2802ZGMS and TMS320F2806NMFS hold AEC-Q100 automotive qualification and operate across the -40°C to 125°C temperature range, suitable for automotive and industrial environments.

Q: What is the difference in product status between these parts?

A: The TMS320F2802ZGMS is classified as Obsolete, indicating discontinued production and limited availability. The TMS320F2806NMFS is classified as Active, indicating current production and ongoing manufacturer support.

Q: Are the package specifications identical?

A: Yes. Both devices use 100-pin LFBGA packaging with Surface Mount mounting type. Pinout and electrical characteristics are identical, enabling direct PCB substitution without layout changes.

Q: Do both parts support the same connectivity interfaces?

A: Yes. Both devices support CANbus, I2C, SCI, SPI, and UART/USART connectivity interfaces with identical peripheral support (POR, PWM, WDT) and 35 I/O pins.
