Texas Instruments F28M36H53B2ZWTS

Overview

F28M36H53B2ZWTS 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 289-ball nFBGA (ZWT) packaging rated for –40°C to 125°C junction temperature. It targets high-reliability industrial motor drives and solar inverters requiring concurrent communication and deterministic control.

For engineers reviewing the F28M36H53B2ZWTS datasheet, F28M36H53B2ZWTS pinout, F28M36H53B2ZWTS application, or F28M36H53B2ZWTS equivalent, key selection criteria include dual-core clock coordination (100/150 MHz pairing), shared 64KB parity RAM absence, missing Ethernet 1588 and USB OTG (vs. P-series), and ZWT package thermal performance at 125°C.

Technical Context

The F28M36H53B2ZWTS implements tightly coupled interprocessor communication (IPC) via 32 handshaking channels and dual 2KB message RAMs, enabling deterministic data exchange between M3 and C28x 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 - all synchronized to the C28x clock domain for precise timing-critical control loops.

Power architecture uses separate 1.2-V digital, 1.8-V analog, and 3.3-V I/O rails with on-chip voltage regulation; safety mechanisms include ECC on all flash, parity on RAM, dual security zones (128-bit password each), and hardware built-in self-test (BIST) for the C28x core. The device lacks ENET 1588 MII and USB-OTG+PHY present in higher-tier P-series variants.

Equivalent & Alternatives

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

Compared with F28M36P53C2ZWTS, the F28M36H53B2ZWTS removes Ethernet and USB peripherals to reduce cost and power, making it optimal for cost-sensitive motor drives where those interfaces are handled externally. Versus TMS320F28388D, it trades dual-C28x determinism for Arm-based protocol agility - critical for cloud-connected industrial edge devices.

Manufacturer

Texas Instruments is a global semiconductor leader specializing in analog, embedded processing, and connectivity technologies, with decades of leadership in industrial and automotive microcontrollers.

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 nanosecond-precision PWM timing.

FAQ

What is the maximum operating junction temperature for F28M36H53B2ZWTS?

The F28M36H53B2ZWTS is rated for –40°C to 125°C junction temperature (S-grade). This is confirmed in the Device Information table and Section 1.1 of the SPRS825F datasheet. The ZWT package's thermal resistance (θ_JA) is 21.5°C/W for Revision A silicon, enabling reliable operation in high-ambient industrial enclosures without forced air cooling when properly heatsinked.

Does F28M36H53B2ZWTS support Ethernet 1588 or USB OTG functionality?

No, F28M36H53B2ZWTS does not include Ethernet 1588 MII or USB-OTG+PHY peripherals. These features are present only in the P63C2 and P53C2 variants, as explicitly shown in Table 3-1 of the SPRS825F datasheet. The H53B2 variant omits both to reduce cost and power consumption while retaining dual-core control and communication capabilities via CAN, UART, and SPI.

How much shared RAM does F28M36H53B2ZWTS have?

F28M36H53B2ZWTS has zero shared RAM. Unlike the P63C2 and P53C2 variants which include 64KB of shared parity RAM, the H53B2 and H33B2 variants omit this memory block entirely, as confirmed in Table 3-1 under "Shared RAM (Parity) (KB)". Data exchange between M3 and C28x subsystems must occur via the dual 2KB IPC message RAMs.

What clock speed combinations are supported between the M3 and C28x cores in F28M36H53B2ZWTS?

F28M36H53B2ZWTS supports M3@100 MHz / C28x@150 MHz, M3@75 MHz / C28x@150 MHz, or M3@100 MHz / C28x@100 MHz, as defined in Table 3-2 of SPRS825F. The constraint arises from shared PLL dividers - selecting M3@125 MHz (available in P-series) is not possible on H53B2 due to its 100 MHz M3 maximum specification.

Is F28M36H53B2ZWTS pin-compatible with other F28M36x devices in the ZWT package?

Yes, F28M36H53B2ZWTS is pin-compatible with all other F28M36x devices in the 289-ball ZWT package (including P63C2, P53C2, H33B2), as confirmed by identical pin diagrams in Section 4.1 and consistent signal descriptions in Table 4-1 of SPRS825F. Functionality differs per variant, but PCB layout and mechanical footprint are identical.
