Product details
Overview
F28M36H33B2ZWTS from Texas Instruments is a dual-core Concerto™ microcontroller integrating an Arm® Cortex®-M3 master subsystem (100 MHz) and a TMS320C28x real-time control subsystem (150 MHz), with 512 KB ECC flash per core, dual 12-bit ADCs (2.88 MSPS total), 12 ePWM modules, 6 comparators with integrated DACs, and 289-ball nFBGA (ZWT) packaging for industrial motor drives and power converters.
For engineers reviewing the F28M36H33B2ZWTS datasheet, F28M36H33B2ZWTS pinout, F28M36H33B2ZWTS application, or F28M36H33B2ZWTS equivalent, key selection criteria include dual-core clock coordination (100/150 MHz), shared 64 KB parity RAM, absence of Ethernet/USB (vs. P-series), and -40°C to 125°C junction temperature rating for high-reliability embedded control.
Technical Context
The F28M36H33B2ZWTS implements strict hardware partitioning: the Cortex-M3 handles communication (5 UARTs, 4 SSI/SPI, 2 I²C, 2 CAN) while the C28x executes deterministic real-time control (ePWM fault protection, eQEP, McBSP). Interprocessor Communication (IPC) uses 32 handshaking channels and 4 KB message RAM to coordinate data transfers between subsystems without bus contention.
Its analog subsystem features two independent 12-bit ADCs with 24 total channels, four sample-and-hold circuits, and six comparator/DAC units-each comparator supports GPIO-triggered trip zones for fast overcurrent protection in motor drive inverters. Clocking employs dual PLLs with dynamic ratio changes and redundant 1.2-V digital / 1.8-V analog / 3.3-V I/O voltage domains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| F28M36H53B2ZWTS | Same package and temperature grade, but Cortex-M3 runs at 100 MHz (identical), C28x at 150 MHz (identical); differs only in flash configuration (512 KB vs. 512 KB) and shared RAM (64 KB vs. 0 KB). | Lacks shared RAM - unsuitable for applications requiring large inter-subsystem data buffers (e.g., high-throughput sensor fusion). | Select F28M36H33B2ZWTS when shared memory bandwidth and deterministic IPC latency are critical for control-communication co-processing. |
| TMS320F28388D | Dual C28x cores (no Arm M3); adds EtherCAT, 10/100 Ethernet MAC, and enhanced analog (32-ch ADC); no USB/OTG or D-CAN. | Better suited for pure real-time control with industrial Ethernet, but lacks native high-level protocol stack offload capability. | Choose TMS320F28388D for EtherCAT-based motion control where communication is handled by dedicated peripherals rather than a general-purpose CPU. |
Compared with F28M36H53B2ZWTS, the F28M36H33B2ZWTS provides essential shared RAM for IPC-intensive architectures; versus TMS320F28388D, it delivers Arm-based protocol flexibility at the cost of reduced analog channel count and no EtherCAT, making it optimal for CAN/Modbus-based distributed control systems.

FAQ
What is the maximum operating junction temperature for F28M36H33B2ZWTS?
The F28M36H33B2ZWTS is rated for -40°C to +125°C junction temperature (S-grade), validated per TI's thermal resistance specifications for the ZWT package. This rating supports deployment in sealed industrial enclosures and automotive under-hood power modules where ambient temperatures exceed 85°C.
Does F28M36H33B2ZWTS support Ethernet or USB connectivity?
No, the F28M36H33B2ZWTS does not include Ethernet MAC or USB OTG peripherals. Unlike the P-series variants (e.g., F28M36P63C2), the H-series omits 10/100 ENET 1588 MII and USB+PHY to reduce cost and silicon area while retaining CAN, UART, SPI, and I²C for industrial fieldbus applications.
How much shared RAM is available on F28M36H33B2ZWTS?
The F28M36H33B2ZWTS includes 64 KB of shared RAM configured with parity protection. This memory is accessible by both the Cortex-M3 and C28x subsystems and is used for IPC message passing, sensor data buffering, and real-time parameter exchange without CPU intervention.
What ADC performance does F28M36H33B2ZWTS deliver?
The F28M36H33B2ZWTS integrates two independent 12-bit ADCs, each capable of up to 2.88 MSPS aggregate sampling across 12 channels. Total conversion time is 347 ns, and both ADCs support simultaneous sampling using four shared sample-and-hold circuits.
Can F28M36H33B2ZWTS replace F28M36H53B2ZWTS in existing designs?
F28M36H33B2ZWTS is not a direct drop-in replacement for F28M36H53B2ZWTS due to the presence of 64 KB shared RAM (vs. 0 KB). Layout and firmware must be verified for memory map compatibility, though pinout, package, and peripheral register sets are identical.
