Overview

TMS320F28064PZT from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, 12-bit 3.46-MSPS ADC, 8 ePWM modules (16 channels), and 54 GPIOs in a 100-pin LQFP package. It targets high-precision motor control, digital power conversion, and industrial automation where deterministic timing, analog integration, and floating-point math acceleration are required.

For engineers reviewing the TMS320F28064PZT datasheet, TMS320F28064PZT pinout, TMS320F28064PZT application, or TMS320F28064PZT equivalent, key selection criteria include its 128KB flash/50KB RAM memory map, dual-sample-and-hold ADC architecture, HRPWM-capable ePWM outputs, on-chip temperature sensor, and support for InstaSPIN-FOC™ firmware libraries in closed-loop control systems.

Technical Context

The TMS320F28064PZT implements a Harvard bus architecture with atomic instruction execution and unified memory programming, enabling deterministic real-time response. Its C28x CPU runs at 90 MHz (11.11-ns cycle time) and supports 16×16 and 32×32 MAC operations alongside a dedicated 32-bit floating-point CLA that executes control law code independently of the main CPU.

Peripheral integration includes a 12-bit dual-sample-and-hold ADC with 16 input channels and 3.46 MSPS throughput, three eCAP modules, four HRCAP modules, two eQEP interfaces, and serial peripherals including two SCI/UARTs, two SPIs, one I²C, one eCAN, and one McBSP - all accessible via a 32-bit peripheral bus with DMA support.

FAQ

What is the maximum operating frequency of the TMS320F28064PZT?

The TMS320F28064PZT operates at a maximum CPU frequency of 90 MHz, corresponding to an 11.11-ns instruction cycle time. This speed is achieved using an internal PLL with external crystal (X1/X2) or internal oscillators, and is fully supported across the –40°C to 105°C industrial temperature range specified for the TMS320F28064PZT.

Does the TMS320F28064PZT include a floating-point unit (FPU)?

Yes, the TMS320F28064PZT integrates a hardware floating-point unit (FPU) that supports native single-precision IEEE 754 operations. This eliminates software-emulated floating-point overhead and accelerates C/C++-based control algorithms such as field-oriented control (FOC) and observer design in the TMS320F28064PZT.

How much on-chip memory does the TMS320F28064PZT have?

The TMS320F28064PZT includes 128KB of on-chip flash memory (organized in eight 16KB sectors), 50KB of on-chip RAM (comprising multiple SARAM blocks), and 1KB of one-time programmable (OTP) ROM. All memory is accessible by both the C28x CPU and CLA, and flash supports secure code protection via the CSM module in the TMS320F28064PZT.

What analog peripherals are integrated into the TMS320F28064PZT?

The TMS320F28064PZT integrates a 12-bit, 3.46-MSPS analog-to-digital converter (ADC) with dual sample-and-hold, 16 input channels, and ratio-metric reference support (VREFHI/VREFLO). It also includes three analog comparators with integrated 10-bit DACs, an on-chip temperature sensor, and dedicated analog I/O pins (AIO0–AIO6) routed to the ADC and comparators in the TMS320F28064PZT.

Is the TMS320F28064PZT pin-compatible with other F2806x devices?

Yes, the TMS320F28064PZT is pin-compatible with other 100-pin PZ/PZP variants in the F2806x family, including TMS320F28069PZT and TMS320F28067PZT. All share identical 100-pin LQFP mechanical footprint, power pin assignments, and GPIO multiplexing - enabling hardware reuse across different memory/peripheral configurations in the TMS320F28064PZT family.
