Overview
DMF2802PZA-60 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 ePWM/ECAP/eQEP peripherals - all operating at 1.8-V core / 3.3-V I/O. Used in brushless DC motor drives and AC-DC power supplies.
For engineers reviewing the DMF2802PZA-60 datasheet, DMF2802PZA-60 pinout, DMF2802PZA-60 application, or DMF2802PZA-60 equivalent, key selection criteria include its 60-MHz deterministic execution, on-chip code security, 35 GPIOs with peripheral multiplexing, and LQFP-100 packaging compatible with industrial temperature range (–40°C to 85°C).
Technical Context
The DMF2802PZA-60 implements the TMS320C28x 32-bit fixed-point CPU with Harvard architecture, atomic instructions, and unified memory model. It executes at 16.67-ns cycle time and supports little-endian data format.

FAQ
What is the maximum operating frequency of the DMF2802PZA-60?
The DMF2802PZA-60 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., 10 MHz crystal) by 6×, and it is fully supported across the full industrial temperature range (–40°C to +85°C) specified for the DMF2802PZA-60.
Does the DMF2802PZA-60 include on-chip flash memory, and is it field-programmable?
Yes, the DMF2802PZA-60 integrates 32K × 16 bits of on-chip flash memory that is electrically erasable and reprogrammable in-system. It supports standard flash programming via JTAG or boot ROM interfaces (SCI, SPI), and its contents are protected by the DMF2802PZA-60's 128-bit code-security module to prevent unauthorized readout.
How many analog-to-digital converter (ADC) channels does the DMF2802PZA-60 support, and what is its conversion speed?
The DMF2802PZA-60 features a 12-bit ADC with 16 input channels (8 on ADCINA, 8 on ADCINB), supporting simultaneous or sequential sampling. Its conversion time is 267 ns (3.75 MSPS), verified per TI SPRS230P Section 8.15 - enabling accurate current/voltage capture within tight PWM switching periods in the DMF2802PZA-60.
What communication interfaces are available on the DMF2802PZA-60?
The DMF2802PZA-60 provides two SPI modules, one SCI (UART) interface, one I²C bus, and no eCAN module. These interfaces support configuration of external DACs, EEPROMs, isolated gate drivers, and host controllers - consistent with the base F2802 variant definition in the DMF2802PZA-60 device comparison table.
Is the DMF2802PZA-60 pin-compatible with other TMS320F280x devices in the LQFP-100 package?
Yes, the DMF2802PZA-60 shares identical pinout and package dimensions (14 mm × 14 mm LQFP-100) with TMS320F2802, TMS320F2801, TMS320C2802, and TMS320C2801 per TI SPRS230P Figure 7-3. Signal mapping, power pin locations, and JTAG interface are functionally aligned - enabling PCB reuse across this 60-MHz device family.
