Texas Instruments TMS320F2802ZGMA

Overview

TMS320F2802ZGMA 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 (3.75 MSPS), three 32-bit CPU timers, six ePWM channels with HRPWM capability, and dual CAN interfaces - all operating at 1.8-V core / 3.3-V I/O. It serves as the central controller in brushless DC motor drives and isolated DC-DC converters.

For engineers reviewing the TMS320F2802ZGMA datasheet, TMS320F2802ZGMA pinout, TMS320F2802ZGMA application, or TMS320F2802ZGMA equivalent, key selection criteria include its 60-MHz deterministic execution, on-chip code security (128-bit key), 100-ball MicroStar BGA package (ZGM), and support for SCI, SPI, I²C, and eCAN peripherals in compact industrial control designs.

Technical Context

The TMS320F2802ZGMA implements the fixed-point TMS320C28x CPU with Harvard architecture, atomic instructions, and unified memory model - enabling deterministic interrupt latency under 6 CPU cycles. Its system control block includes an on-chip oscillator, PLL, watchdog timer, and low-power modes (IDLE/STANDBY/HALT) with individual peripheral clock gating.

Peripheral integration centers on real-time control: six ePWM modules support dead-time insertion and trip-zone protection; two eCAP modules capture edge timing with 32-bit resolution; one eQEP interface decodes quadrature encoder signals; and the 12-bit ADC features dual sample-and-hold, simultaneous sampling across two 8-channel MUX banks, and internal/external reference selection.

FAQ

What is the maximum operating frequency of the TMS320F2802ZGMA?

The TMS320F2802ZGMA operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67-ns instruction cycle time. This speed is achieved using the on-chip PLL with an external crystal or oscillator input. The device does not support 100-MHz operation - that capability is reserved for the F2806/F2808/F2809 variants. All timing-critical peripherals (ePWM, eCAP, ADC) are synchronized to this 60-MHz clock domain.

Does the TMS320F2802ZGMA include on-chip flash memory, and what is its capacity?

Yes, the TMS320F2802ZGMA includes 32K × 16 bits (64 KB) of on-chip flash memory. This flash is rated for 10,000 write/erase cycles and supports in-application programming (IAP). It stores user firmware, calibration tables, and configuration data. The device also includes 1K × 16 OTP memory for permanent security keys or factory-trimmed parameters - both flash and OTP are protected by the 128-bit code-security module.

How many PWM outputs does the TMS320F2802ZGMA support, and what advanced features are included?

The TMS320F2802ZGMA supports six ePWM modules (ePWM1–ePWM6), providing up to 12 complementary PWM outputs. Three of these (ePWM1A/2A/3A) support high-resolution PWM (HRPWM) with 150-ps minimum pulse-width resolution. Each ePWM includes dead-band generation, trip-zone protection (TZ1–TZ6), and synchronization inputs/outputs - essential for safe inverter gate driving in motor and power applications.

What ADC capabilities does the TMS320F2802ZGMA provide for real-time control?

The TMS320F2802ZGMA integrates a 12-bit, 16-channel analog-to-digital converter with a 3.75 MSPS sampling rate (267 ns conversion time). It features two independent 8-channel input MUX banks (A and B), dual sample-and-hold circuits, and flexible triggering (software, ePWM, GPIO). Simultaneous sampling across both banks enables accurate phase-current reconstruction in three-phase motor control.

Is the TMS320F2802ZGMA pin-compatible with other devices in the F280x family?

No - the TMS320F2802ZGMA shares the same 100-ball ZGM BGA package footprint with F2801, F2806, F2808, and F2809, but it is not functionally or electrically pin-compatible. Key differences include missing peripherals (e.g., no eQEP2, limited eCAN mailbox depth, no H0 SARAM), different ADC channel mapping, and distinct power pin assignments. Board-level reuse requires verification of signal routing, power integrity, and peripheral initialization sequences.
