Texas Instruments F28M36P63C2ZWTS

Overview

F28M36P63C2ZWTS from Texas Instruments is a dual-core Concerto™ microcontroller integrating an Arm® Cortex®-M3 (125 MHz) for communications and a TMS320C28x (150 MHz) for real-time control, with 1MB ECC flash, 128KB RAM (ECC/parity), dual 12-bit ADCs (2.88 MSPS), 12 ePWM modules, and 10/100 ENET 1588 MII - deployed in solar string inverters and industrial AC drive control modules.

For engineers reviewing the F28M36P63C2ZWTS datasheet, F28M36P63C2ZWTS pinout, F28M36P63C2ZWTS application, or F28M36P63C2ZWTS equivalent, key selection criteria include dual-core clock coordination (125/150 MHz max), IPC message RAM (2KB), shared 64KB parity RAM, ZWT nFBGA package (289-ball, 16×16 mm), and –40°C to 125°C junction temperature rating.

Technical Context

The F28M36P63C2ZWTS implements tightly coupled subsystems: the Master Subsystem (Cortex-M3) handles Ethernet 1588, USB OTG + PHY, dual CAN, five UARTs, and external peripheral interface (EPI); the Control Subsystem (C28x) executes high-precision motor control via 12 ePWMs (24 outputs, 16 high-resolution), six eCAPs, three eQEPs, and VCU-accelerated complex math. Both cores share analog resources and IPC messaging infrastructure.

Its clocking architecture supports dynamic PLL ratio changes, with strict integer divide constraints between C28x and ADC clocks (e.g., 150 MHz C28x → 2.88 MSPS ADC). Safety features include ECC on flash/RAM, dual security zones (128-bit password), NMI watchdogs per subsystem, and critical register lock protection - targeting industrial safety certification support.

FAQ

What is the maximum operating temperature range for the F28M36P63C2ZWTS?

The F28M36P63C2ZWTS is rated for –40°C to 125°C junction temperature (S-grade), validated per TI's thermal resistance specifications for the ZWT package. This enables deployment in high-ambient environments such as enclosed motor drives and outdoor solar inverters without derating. The device integrates on-chip thermal monitoring circuitry and supports software-triggered shutdown via the C28x or Cortex-M3 subsystems. F28M36P63C2ZWTS operates reliably under continuous thermal stress within this range when PCB layout follows TI's recommended copper pour and via guidelines.

Does the F28M36P63C2ZWTS support pin-compatible migration from other Concerto devices?

No - the F28M36P63C2ZWTS uses the 289-ball ZWT nFBGA package, which is mechanically identical across the F28M36x series (e.g., F28M36P53C2ZWTS, F28M36H53B2ZWT), but electrical compatibility requires verification. While pinout is shared, differences in peripheral enablement (e.g., ENET 1588 present only in P63/P53 variants) and flash/RAM mapping mean direct PCB reuse is not guaranteed. F28M36P63C2ZWTS requires explicit validation of signal routing for unused pins and power domain sequencing per the device-specific datasheet.

How does the IPC mechanism work between the Cortex-M3 and C28x subsystems in the F28M36P63C2ZWTS?

The F28M36P63C2ZWTS implements a hardware-accelerated Interprocessor Communication (IPC) system with 32 handshaking channels and dedicated 2KB message RAM (1KB CTOM, 1KB MTOC). Each subsystem accesses its own message RAM segment via AXI/AHB bus; IPC interrupts trigger on channel assertion. Software uses TI's IPC library to manage mailbox-style transfers, semaphore synchronization, and data coherency - enabling deterministic, low-latency coordination (e.g., C28x sends PWM update flags, Cortex-M3 responds with new reference values). F28M36P63C2ZWTS supports both polling and interrupt-driven IPC modes.

Can the F28M36P63C2ZWTS ADCs operate simultaneously at full speed?

Yes - the F28M36P63C2ZWTS supports concurrent sampling of both 12-bit ADC modules at up to 2.88 MSPS aggregate rate (1.44 MSPS per ADC), provided the C28x clock is set to 150 MHz and the ADC clock divider maintains an integer ratio. Each ADC has independent sample-and-hold circuits and conversion pipelines, allowing interleaved or synchronized acquisition across all 24 channels. F28M36P63C2ZWTS includes hardware triggers from ePWM timers and GPIOs to precisely align sampling with power stage switching events.

What safety certifications does the F28M36P63C2ZWTS support out-of-the-box?

The F28M36P63C2ZWTS includes hardware features aligned with IEC 61508 SIL-2 and ISO 13849 PL d requirements: ECC on flash/RAM, parity on critical RAM, dual NMI watchdogs (one per subsystem), register lock protection, and secure boot with 128-bit password zones. However, system-level certification requires external validation - TI provides safety manuals, FMEDA reports, and diagnostic software libraries. F28M36P63C2ZWTS itself is not pre-certified; its safety value lies in enabling certified system designs when integrated per TI's functional safety documentation.
