Texas Instruments F28M36H53B2ZWTQ

Overview

F28M36H53B2ZWTQ from Texas Instruments is a dual-core Concerto™ microcontroller integrating an Arm® Cortex®-M3 (100 MHz) master subsystem and a TMS320C28x (150 MHz) real-time control subsystem on a single die. It features 512 KB ECC flash per core, dual 12-bit ADCs (2.88 MSPS total), 6 integrated comparators with DACs, and 142 GPIOs - deployed in industrial motor drives and solar inverters requiring deterministic control and robust communication.

For engineers reviewing the F28M36H53B2ZWTQ datasheet, F28M36H53B2ZWTQ pinout, F28M36H53B2ZWTQ application, or F28M36H53B2ZWTQ equivalent, key selection criteria include dual-core clock coordination (100/150 MHz pairing), absence of Ethernet/USB peripherals versus P-series variants, shared RAM allocation (64 KB parity), and ZWT nFBGA package compatibility with thermal design for 105°C junction operation.

Technical Context

The F28M36H53B2ZWTQ implements strict hardware partitioning: the Cortex-M3 handles protocol stacks (CAN, UART, I²C, SSI, SPI) and system management, while the C28x executes time-critical control loops using ePWM (12 modules, 24 outputs), eCAP (6), eQEP (3), and FPU-accelerated math. Interprocessor Communication (IPC) uses 32 handshaking channels and 4 KB message RAM to synchronize data transfers between subsystems without bus contention.

Its analog subsystem integrates two independent 12-bit ADCs (12-channel each, 347 ns conversion time) with four sample-and-hold circuits and six comparator/DAC units supporting fast overcurrent trip response (<100 ns propagation delay). Clocking employs dual PLLs with dynamic ratio adjustment, and voltage regulation provides separate 1.2-V (digital), 1.8-V (analog), and 3.3-V (I/O) domains.

Manufacturer

Texas Instruments is a global semiconductor company headquartered in Dallas, Texas, delivering analog and embedded processing solutions for industrial, automotive, and communications markets since 1930.

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 protocol stack execution and deterministic PWM timing.

FAQ

What is the maximum operating frequency of the Cortex-M3 core in the F28M36H53B2ZWTQ?

The Cortex-M3 core in the F28M36H53B2ZWTQ operates at a maximum frequency of 100 MHz. This speed is fixed for this variant and differs from the P-series (125 MHz); it is coordinated with the C28x core's 150 MHz operation via shared clock dividers to maintain timing integrity across subsystems. The F28M36H53B2ZWTQ datasheet confirms this value in Table 3-1 and Section 1.1.

Does the F28M36H53B2ZWTQ support Ethernet or USB interfaces?

No, the F28M36H53B2ZWTQ does not include Ethernet or USB peripherals. Unlike the P63C2/P53C2 variants, the H53B2/H33B2 series omits the 10/100 ENET 1588 MII and USB OTG + PHY modules. Its communication suite consists of five UARTs, four SSIs, one SPI, two I²Cs, and two CAN modules - sufficient for CANopen, Modbus, and serial fieldbus implementations.

How much shared RAM is available in the F28M36H53B2ZWTQ?

The F28M36H53B2ZWTQ provides 64 KB of shared RAM with parity protection. This memory is accessible by both the Cortex-M3 and C28x subsystems and is used for IPC message passing, shared configuration tables, and real-time data buffers. Note that the H33B2 variant has zero shared RAM, making the H53B2ZWTQ the preferred choice for tightly coupled dual-core applications.

What analog features distinguish the F28M36H53B2ZWTQ from standard C2000 MCUs?

The F28M36H53B2ZWTQ integrates dual 12-bit ADCs (2.88 MSPS aggregate), four sample-and-hold circuits, and six comparator/DAC units - all synchronized to the C28x clock domain. This enables simultaneous sampling of multiple motor phases and fast overcurrent response (<100 ns comparator propagation), exceeding the analog capability of single-core F28004x or F2837x devices.

Is the F28M36H53B2ZWTQ pin-compatible with other F28M36x devices in the ZWT package?

Yes, the F28M36H53B2ZWTQ is pin-compatible with all F28M36x devices in the 289-ball ZWT nFBGA package, including F28M36P63C2ZWT, F28M36P53C2ZWT, and F28M36H33B2ZWT. Signal assignments, power/ground ball locations, and thermal pad layout are identical; only functional peripheral enablement (e.g., ENET, USB) differs per variant.
