Product details
Overview
TMS320F2802ZGMS from Texas Instruments is a 60-MHz C28x-core digital signal processor optimized for real-time motor control and digital power conversion. It integrates 32KB flash, 6KB SARAM, 12-bit 16-channel ADC (267 ns conversion), three 32-bit CPU timers, and six ePWM channels with HRPWM capability-enabling precise gate timing in brushless DC and PMSM motor drives.
For engineers reviewing the TMS320F2802ZGMS datasheet, TMS320F2802ZGMS pinout, TMS320F2802ZGMS application, or TMS320F2802ZGMS equivalent, key selection criteria include its 100-ball MicroStar BGA (ZGM) package, 1.8-V core/3.3-V I/O supply, eCAN-A interface, and A-grade temperature range (–40°C to 85°C) for industrial embedded control.
Technical Context
The TMS320F2802ZGMS implements the fixed-point TMS320C28x CPU with Harvard architecture, atomic operations, and unified memory model-delivering deterministic 16.67-ns instruction cycle time at 60 MHz. Its peripheral set centers on real-time control: ePWM modules support dead-time insertion and trip-zone protection, while the PIE block routes 43 peripheral interrupts with low-latency response.
On-chip system resources include boot ROM with SCI/SPI/I²C boot modes, watchdog timer, PLL-based clock generation, and 35 GPIOs with input filtering and external interrupt mapping. The device lacks H0 SARAM and L1 SARAM blocks present in higher-tier F280x variants, reflecting its cost-optimized positioning within the C2000™ family.

FAQ
What is the maximum operating frequency of the TMS320F2802ZGMS?
The TMS320F2802ZGMS operates at a maximum CPU frequency of 60 MHz, delivering a 16.67-ns instruction cycle time. This speed is achieved using an internal PLL that multiplies the input clock (e.g., 20 MHz crystal on X1/X2) and is validated across the full –40°C to +85°C temperature range specified for the TMS320F2802ZGMS.
Does the TMS320F2802ZGMS support CAN communication?
Yes, the TMS320F2802ZGMS integrates one enhanced Controller Area Network (eCAN-A) module compliant with ISO 11898-1. It supports standard (11-bit) and extended (29-bit) identifiers, 32 message objects, and loopback/self-test modes-enabling robust communication in motor drive and industrial automation networks.
How much on-chip memory does the TMS320F2802ZGMS provide?
The TMS320F2802ZGMS includes 32K × 16-bit (64 KB) on-chip flash memory for program storage and 6K × 16-bit (12 KB) single-access SARAM for runtime variables and stack. It also contains 4K × 16-bit boot ROM and 1K × 16-bit OTP for secure configuration storage-all accessible without external memory interfaces.
What ADC performance can be expected from the TMS320F2802ZGMS?
The TMS320F2802ZGMS features a 12-bit successive-approximation ADC with 16 input channels (dual 8-channel mux), two sample-and-hold circuits, and a minimum conversion time of 267 ns (3.75 MSPS). Its design supports simultaneous sampling of up to two channels and internal/external reference selection for flexible sensor interfacing.
Is the TMS320F2802ZGMS pin-compatible with other C2000™ devices?
The TMS320F2802ZGMS shares the same 100-ball ZGM package and pinout with TMS320F2801ZGMS, TMS320F2806ZGMS, and TMS320F2808ZGMS-but functional differences exist. For example, it lacks eCAN-B and second SCI found in F2808, and has reduced SARAM versus F2806. Pin compatibility does not guarantee drop-in replacement without firmware and peripheral validation.
