Texas Instruments F28M36H33C2ZWTT

Overview

F28M36H33C2ZWTT from Texas Instruments is a dual-core Concerto™ microcontroller integrating an Arm® Cortex®-M3 (100 MHz) and TMS320C28x (150 MHz) real-time control CPU on a single die, with 512KB ECC flash per core, dual 12-bit ADCs (2.88 MSPS total), 12 ePWM modules, 6 comparators with integrated DACs, and 10/100 ENET 1588 MII - deployed in industrial motor drives and solar inverters.

For engineers reviewing the F28M36H33C2ZWTT datasheet, F28M36H33C2ZWTT pinout, F28M36H33C2ZWTT application, or F28M36H33C2ZWTT equivalent, key selection criteria include dual-core clock coordination (Cortex-M3 @ 100 MHz / C28x @ 150 MHz), shared 64KB parity RAM, IPC message RAM for interprocessor communication, and ZWT nFBGA package compatibility with thermal design for –40°C to 105°C operation.

Technical Context

The F28M36H33C2ZWTT implements a tightly coupled dual-subsystem architecture: the Master Subsystem (Cortex-M3) handles Ethernet 1588, USB OTG + PHY, dual CAN, and five UARTs, while the Control Subsystem (C28x) executes deterministic real-time control using 12 ePWMs with high-resolution outputs, six eCAPs, three eQEPs, and VCU-accelerated complex math. Both subsystems share analog resources including two synchronized 12-bit ADCs and six comparator/DAC units.

Clocking is managed via independent PLLs with dynamic ratio changes; the system enforces integer divide ratios between C28x and ADC clocks. Safety features include ECC on all flash, parity on RAM, dual security zones (128-bit password per zone), and NMI watchdogs for both CPUs - meeting requirements for industrial functional safety certification support.

FAQ

What is the maximum operating frequency of each core in the F28M36H33C2ZWTT?

The F28M36H33C2ZWTT features an Arm Cortex-M3 core rated at 100 MHz and a TMS320C28x core rated at 150 MHz. These frequencies are fixed per the H33 variant designation and cannot be overclocked. The datasheet specifies that maintaining integer clock ratios between the C28x and ADC subsystems is mandatory for correct operation - so actual usable frequencies depend on system clock configuration.

Does the F28M36H33C2ZWTT include integrated Ethernet PHY hardware?

Yes, the F28M36H33C2ZWTT integrates a full 10/100 ENET 1588 Media Independent Interface (MII) with on-die PHY - eliminating the need for an external Ethernet transceiver. This includes IEEE 1588 precision time protocol hardware timestamping registers, enabling sub-microsecond clock synchronization across distributed nodes in industrial networks.

How many analog-to-digital converter channels does the F28M36H33C2ZWTT support?

The F28M36H33C2ZWTT supports 24 total ADC input channels - split across two independent 12-bit ADC modules (ADC1 and ADC2), each with 12 inputs. Each ADC achieves up to 2.88 MSPS aggregate sampling rate and includes four sample-and-hold circuits, allowing simultaneous sampling of multiple current/voltage signals in motor control applications.

What security features are implemented in the F28M36H33C2ZWTT?

The F28M36H33C2ZWTT implements dual security zones (one per subsystem), each protected by a 128-bit password; ECC on all flash memory; parity on RAM blocks; and lockable critical registers. It also includes a Code Security Module (CSM) that prevents unauthorized readout of flash contents and supports secure boot with authenticated firmware images.

Is the F28M36H33C2ZWTT pin-compatible with other devices in the F28M36x family?

Yes, the F28M36H33C2ZWTT shares the same 289-ball ZWT nFBGA package and pinout with all members of the F28M36x family, including F28M36P63C2ZWTT, F28M36P53C2ZWTT, and F28M36H53B2ZWTT. This enables hardware reuse across performance tiers - though peripheral enablement (e.g., USB, Ethernet) and clock speeds differ per variant and must be verified in software initialization.
