Texas Instruments TMS320F2802PZS

Overview

TMS320F2802PZS from Texas Instruments is a 60-MHz C28x digital signal processor optimized for real-time motor control and digital power conversion. It integrates a 32-bit CPU, 32K × 16 flash memory, 6K × 16 SARAM, 12-bit 16-channel ADC with 267-ns conversion time, three 32-bit CPU timers, and six ePWM channels with HRPWM capability - deployed in industrial inverters, servo drives, and DC-DC controllers.

For engineers reviewing the TMS320F2802PZS datasheet, TMS320F2802PZS pinout, TMS320F2802PZS application, or TMS320F2802PZS equivalent, key selection criteria include its 60-MHz deterministic execution, 1.8-V core/3.3-V I/O supply, -40°C to 125°C extended temperature rating (S-grade), and integrated eCAN-A, SCI-A, SPI-A/B, and I²C-A peripherals for closed-loop system integration.

Technical Context

The TMS320F2802PZS implements the fixed-point TMS320C28x CPU core with Harvard architecture, atomic instructions, and unified memory model - enabling deterministic interrupt latency under 6 CPU cycles. Its clock system includes an on-chip oscillator, PLL, and programmable peripheral clock dividers supporting synchronous operation of PWM, ADC, and serial modules.

Real-time control is enhanced by the Peripheral Interrupt Expansion (PIE) block servicing 43 peripheral interrupts, three independent ePWM modules (6 outputs total), two eCAP inputs, one eQEP interface, and a 12-bit dual-sample-and-hold ADC with internal reference and simultaneous sampling across two 8-channel MUX banks.

FAQ

What is the maximum operating frequency of the TMS320F2802PZS?

The TMS320F2802PZS operates at a maximum CPU frequency of 60 MHz, delivering a 16.67-ns instruction cycle time. This speed is achieved using an on-chip PLL that multiplies the input clock (from crystal or external source), and it is fully supported across the device's entire specified temperature range of –40°C to +125°C. The TMS320F2802PZS does not support 100-MHz operation - that capability is reserved for higher-tier variants like the F28027PZS.

Does the TMS320F2802PZS include an integrated ADC, and what are its key timing specifications?

Yes, the TMS320F2802PZS integrates a 12-bit successive-approximation ADC with 16 input channels organized in two 8-channel banks (ADCINA0–7 and ADCINB0–7). Its conversion time is 267 ns (3.75 MSPS), and it supports simultaneous sampling across both banks using dual sample-and-hold circuits. Internal reference options include VREFLO/VREFHI or external ADCREFP/ADCREFM/ADCREFIN connections.

What package and temperature grade does the TMS320F2802PZS use?

The TMS320F2802PZS uses a 100-pin LQFP (PZ) package measuring 14.0 mm × 14.0 mm, with standard lead finish and RoHS compliance. Its temperature grade is 'S', meaning it is rated for continuous operation from –40°C to +125°C - validated for industrial and automotive under-hood environments. This differs from the 'A' grade (–40°C to +85°C) used in commercial variants.

How many PWM outputs does the TMS320F2802PZS support, and what is the resolution of its high-resolution PWM?

The TMS320F2802PZS supports six ePWM outputs across three ePWM modules (ePWM1–3), each providing complementary A/B signals. Three of these outputs (ePWM1A/2A/3A) are enhanced with High-Resolution PWM (HRPWM) capability, achieving 150-ps effective resolution via the MEP (Minimum Edge Pulse) module - enabling precise dead-time control critical for minimizing shoot-through in bridge drivers.

Is the TMS320F2802PZS pin-compatible with other devices in the F280x family?

Yes, the TMS320F2802PZS shares identical 100-pin LQFP (PZ) pinout with TMS320F2801PZS, TMS320F2806PZS, and TMS320F2808PZS - including matching signal assignments for GPIO, ADC, ePWM, eCAN, SCI, SPI, and I²C. However, peripheral feature sets differ (e.g., F2808 includes dual eCAN modules and more RAM), so firmware and schematic design must verify functional alignment beyond pin mapping.
