Texas Instruments F28M36H33C2ZWTQ

Overview

F28M36H33C2ZWTQ 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 dual 12-bit ADCs (2.88 MSPS, 24 total channels), 12 ePWM modules (24 outputs, 16 high-resolution), 6 comparators with integrated 10-bit DACs, and 142 GPIOs - deployed in industrial motor drives and solar inverters.

For engineers reviewing the F28M36H33C2ZWTQ datasheet, F28M36H33C2ZWTQ pinout, F28M36H33C2ZWTQ application, or F28M36H33C2ZWTQ equivalent, key selection criteria include dual-core clock coordination (100/150 MHz pairing), shared 64KB parity RAM absence, ZWT nFBGA package compatibility, and lack of Ethernet/USB peripherals versus P-series variants.

Technical Context

The F28M36H33C2ZWTQ implements strict hardware separation between its Master (Cortex-M3) and Control (C28x) subsystems via dedicated AHB/APB buses, IPC handshaking channels, and isolated memory maps - enabling concurrent communication stack execution and deterministic real-time control without software arbitration. Its analog subsystem features two independent 12-bit ADCs with synchronized sampling across 24 channels and six comparator-DAC units for fast overcurrent trip generation.

Clocking uses a shared crystal oscillator with independent PLLs per core; the M3 runs at 100 MHz while the C28x operates at 150 MHz - a configuration validated in Table 3-2 of SPRS825F. Safety mechanisms include ECC on both flash banks, parity on all RAM blocks, dual security zones (128-bit password each), and critical register lock protection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-core real-time control applications.

Compared with F28M36P53C2ZWT, the F28M36H33C2ZWTQ omits Ethernet/USB to reduce cost and power, making it optimal for cost-sensitive inverters where CAN/UART suffices; versus TMS320F28388D, it trades raw control determinism for Arm-based protocol stack scalability in hybrid communication-control systems.

Availability

F28M36H33C2ZWTQ is available at Aetrix Electronics and suitable for industrial motor drives, solar inverters, uninterruptible power supplies, and automated sorting equipment requiring stable component supply across extended production lifecycles.

Supply support for F28M36H33C2ZWTQ includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Texas Instruments is a global semiconductor company headquartered in Dallas, Texas, delivering analog and embedded processing solutions for industrial, automotive, and personal electronics markets.

The F28M36x Concerto™ family was designed to unify communication and real-time control in a single chip - targeting solar inverters, motor drives, and industrial automation systems needing both high-level protocol stacks and sub-microsecond PWM timing.

FAQ

What is the maximum operating frequency of each core in the F28M36H33C2ZWTQ?

The F28M36H33C2ZWTQ features an Arm Cortex-M3 core rated at 100 MHz and a TMS320C28x core rated at 150 MHz. These frequencies are validated per Table 3-2 in SPRS825F and reflect the highest stable clock speeds achievable under recommended operating conditions. The F28M36H33C2ZWTQ does not support the 125-MHz M3 option found in P-series variants.

Does the F28M36H33C2ZWTQ include Ethernet or USB peripherals?

No, the F28M36H33C2ZWTQ excludes both 10/100 ENET 1588 MII and USB OTG peripherals - a key distinction from the P63C2 and P53C2 variants. This omission reduces silicon area and power consumption, making the F28M36H33C2ZWTQ suitable for applications relying on CAN, UART, or SPI for communication instead of Ethernet or USB.

How much shared RAM does the F28M36H33C2ZWTQ have, and why does it matter?

The F28M36H33C2ZWTQ has 0 KB of shared RAM, unlike the P63C2/P53C2 variants which offer 64 KB. This means inter-core data exchange must occur exclusively through the 2KB IPC message RAMs - constraining bulk data transfer bandwidth but simplifying memory coherency management. Designers must optimize IPC usage for low-latency, small-payload communication.

What analog features differentiate the F28M36H33C2ZWTQ from standard C2000 MCUs?

The F28M36H33C2ZWTQ integrates dual 12-bit ADCs (2.88 MSPS, 24 channels total), four Sample-and-Hold circuits, and six comparators with integrated 10-bit DACs - all accessible to the C28x core. Unlike single-core C2000 devices, this analog subsystem is shared and synchronized across both cores, enabling coordinated sampling and hardware-triggered trip actions directly to ePWM modules.

Is the F28M36H33C2ZWTQ pin-compatible with other F28M36x devices in the ZWT package?

Yes, the F28M36H33C2ZWTQ is pin-compatible with all F28M36x devices offered in the 289-ball ZWT nFBGA package, including F28M36P63C2ZWT and F28M36P53C2ZWT. Signal assignments, power pin locations, and thermal pad layout are identical; functional differences arise only from internal peripheral enablement and memory mapping - verified in Figures 4-1 through 4-5 and Table 4-1 of SPRS825F.
