Texas Instruments TMS320F28015NMFA

Overview

TMS320F28015NMFA from Texas Instruments is a 60-MHz C28x-core digital signal processor optimized for real-time motor control and digital power conversion. It integrates 16K × 16 flash, 6K × 16 SARAM, 12-bit 16-channel ADC with 267-ns conversion time, three 32-bit CPU timers, and ePWM/ECAP/eQEP peripherals - deployed in brushless DC motor drives and isolated DC-DC converters.

For engineers reviewing the TMS320F28015NMFA datasheet, TMS320F28015NMFA pinout, TMS320F28015NMFA application, or TMS320F28015NMFA equivalent, key selection criteria include its 60-MHz deterministic execution, 1.8-V core / 3.3-V I/O voltage architecture, 35 GPIOs with peripheral multiplexing, and support for SCI-A and SPI-A/B serial interfaces in industrial embedded control designs.

Technical Context

The TMS320F28015NMFA implements the fixed-point TMS320C28x CPU with Harvard bus architecture, atomic operations, and unified memory model - enabling efficient C/C++ code execution for closed-loop control algorithms. Its system clock derives from an on-chip oscillator or external crystal (X1/X2), routed through a PLL to generate SYSCLKOUT at 60 MHz.

Peripheral integration includes ePWM1–ePWM3 modules (6 total PWM outputs), ECAP1–ECAP2 (2 capture inputs), and SCI-A and SPI-A/B for host communication. The device lacks eCAN and second SCI, distinguishing it from higher-tier F280x variants - confirming its targeted role in cost-sensitive, non-automotive control systems.

FAQ

What is the maximum operating frequency of the TMS320F28015NMFA?

The TMS320F28015NMFA operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67-ns instruction cycle time. This is achieved using the on-chip PLL with an external crystal (X1/X2) or oscillator input. The device does not support the 100-MHz mode found in F2809/F2808 variants, and its performance is fixed at this 60-MHz rate per TI's device comparison tables.

Does the TMS320F28015NMFA include an integrated CAN controller?

No, the TMS320F28015NMFA does not include an eCAN module. As confirmed in Table 6-2 of the official datasheet, eCAN-A is explicitly omitted from the F28015 and F28015-Q1 devices. This distinguishes it from F28027/F28035 parts that integrate eCAN-A. Communication relies solely on SCI-A and SPI-A/B interfaces.

What package type and pin count does the TMS320F28015NMFA use?

The TMS320F28015NMFA uses a 100-pin LQFP (PZ) package with 14.0 mm × 14.0 mm body dimensions and 0.5-mm lead pitch. This matches the mechanical specifications listed in TI's "Mechanical, Packaging, and Orderable Information" section and is visually confirmed in Figure 7-4 of the datasheet, which shows the TMS320F2801x PZ pinout.

How much on-chip RAM and flash memory does the TMS320F28015NMFA provide?

The TMS320F28015NMFA integrates 6K × 16-bit single-access RAM (SARAM) distributed across L0, M0, and M1 blocks, and 16K × 16-bit on-chip flash memory. These values are explicitly stated in the "On-chip memory" section under "F2801x: 16K × 16 flash, 6K × 16 SARAM" and verified in Table 6-2's "Device Comparison (60-MHz Devices)".

What ADC performance specifications apply to the TMS320F28015NMFA?

The TMS320F28015NMFA features a 12-bit successive-approximation ADC with 16 input channels (8 per sample-and-hold), 267-ns conversion time (3.75 MSPS), and support for single or simultaneous conversions. Internal/external reference selection and ADCSOCA/B trigger flexibility are confirmed in the "12-bit ADC" feature list and Table 6-2, which assigns "267 ns" and "3.75 MSPS" exclusively to F2801x devices.
