Texas Instruments F28M36H53C2ZWTT

Overview

F28M36H53C2ZWTT from Texas Instruments is a dual-core Concerto™ microcontroller integrating an Arm® Cortex®-M3 (100 MHz) for communications and a TMS320C28x (150 MHz) for real-time control, with 512 KB ECC flash per core, dual 12-bit ADCs (2.88 MSPS total), 12 ePWM modules, and 6 comparators with integrated DACs - deployed in industrial motor drives and solar inverters.

For engineers reviewing the F28M36H53C2ZWTT datasheet, F28M36H53C2ZWTT pinout, F28M36H53C2ZWTT application, or F28M36H53C2ZWTT equivalent, key selection criteria include dual-core clock coordination (Cortex-M3 @ 100 MHz / C28x @ 150 MHz), shared 64 KB parity RAM, ZWT nFBGA package compatibility, and absence of Ethernet/USB peripherals versus P-series variants.

Technical Context

The F28M36H53C2ZWTT implements tightly coupled interprocessor communication (IPC) via 32 handshaking channels and dual 2 KB message RAMs, enabling deterministic data exchange between M3 and C28x subsystems without bus contention. Its analog subsystem integrates two independent 12-bit ADCs with 24 total input channels, four sample-and-hold circuits, and six comparator-DAC units supporting fast overcurrent trip response.

Clocking uses separate PLLs for each core with dynamic ratio adjustment; the M3 subsystem runs at 100 MHz while the C28x operates at 150 MHz - constrained by integer divide relationships to maintain synchronous sampling. Safety features include ECC on all flash, parity on RAM, dual security zones (128-bit password), and critical register lock protection.

FAQ

What is the maximum operating frequency of each core in the F28M36H53C2ZWTT?

The F28M36H53C2ZWTT features an Arm Cortex-M3 core rated at 100 MHz and a TMS320C28x core rated at 150 MHz. These frequencies are fixed per device variant and cannot be overclocked. The actual achievable speed depends on clock divider settings and voltage conditions, but the silicon is characterized and guaranteed for these maximums under recommended operating conditions.

Does the F28M36H53C2ZWTT support Ethernet or USB connectivity?

No, the F28M36H53C2ZWTT does not include Ethernet MAC/PHY or USB OTG hardware. This distinguishes it from the P-series variants (e.g., F28M36P53C2ZWT). For designs requiring 10/100 ENET 1588 or USB functionality, the F28M36H53C2ZWTT must be replaced with a P-series part or supplemented with external PHY/interface ICs.

How much shared RAM is available on the F28M36H53C2ZWTT?

The F28M36H53C2ZWTT provides 64 KB of shared RAM implemented as eight 8-KB parity-protected blocks (S0–S7). This memory is accessible by both the Cortex-M3 and C28x subsystems and is commonly used for IPC message passing, shared configuration tables, and real-time data buffers in coordinated control applications.

What analog peripherals are integrated into the F28M36H53C2ZWTT?

The F28M36H53C2ZWTT integrates two independent 12-bit ADCs (ADC1 and ADC2), each supporting up to 12 input channels and 2.88 MSPS aggregate sampling. It also includes six analog comparators with integrated 10-bit DACs, four sample-and-hold circuits, and dedicated analog power/ground pins (VDDA/VSSA) for noise-sensitive signal acquisition.

Is the F28M36H53C2ZWTT pin-compatible with other F28M36x devices in the ZWT package?

Yes, all F28M36x devices in the ZWT nFBGA package - including F28M36H53C2ZWTT, F28M36P53C2ZWT, and F28M36H53B2ZWTT - share identical pinouts and ball assignments. This allows direct PCB reuse across variants, provided the design does not rely on peripherals absent in the H53C2 version (e.g., Ethernet or USB signals).
