Product details

The TMS320F28334PTPS: The 32-bit C28x core runs at 150 MHz.

256 KB Flash and 34K x 16 RAM — firmware and data budget

Program memory is 256 KB of Flash, organized as 128K x 16. RAM is 34K x 16.

Extended temperature range and package

The TMS320F28334PTPS carries an EOL hot lifecycle status. The last-time-buy window is active.

On-chip peripherals include DMA, POR, PWM, and WDT. Connectivity covers CANbus, EBI/EMI, I²C, McBSP, SCI, SPI, and UART/USART — enough for a multi-axis drive communicating over CANopen or a power converter reporting via SPI to a host controller. The 16-channel 12-bit ADC captures three-phase currents and DC-link voltage in a single conversion sequence.

Frequently asked questions

Is TMS320F28334PTPS obsolete or last time buy?

Yes, the TMS320F28334PTPS carries an EOL hot lifecycle status. The last-time-buy window is open now; once it closes, the part will only be available through surplus and broker channels. Secure your production quantity or qualify a replacement before the window ends.

Is TMS320F28334PTPS equivalent to TMS320F28335?

The TMS320F28335 is pin-compatible and shares the same 176-HLQFP package, 150 MHz core, and peripheral set, but doubles the Flash to 512 KB. It is a direct drop-in replacement if your firmware fits the larger memory — no PCB change needed.

What is the operating voltage range of TMS320F28334PTPS?

The supply voltage range is 1.805 V to 1.995 V on Vcc/Vdd. The I/O banks are 3.3 V tolerant; the core runs from the lower rail.

What is the TMS320F28334PTPS datasheet and pinout?

The datasheet and pinout are available from Texas Instruments under the base product number TMS320F28334. The 176-pin HLQFP pinout matches the TMS320F28335, so the same reference design applies.
