Texas Instruments F28M36P63C2ZWTQ

Overview

F28M36P63C2ZWTQ 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 F28M36P63C2ZWTQ datasheet, F28M36P63C2ZWTQ pinout, F28M36P63C2ZWTQ application, or F28M36P63C2ZWTQ equivalent, key selection criteria include dual-core clock coordination (125/150 MHz max), shared 64KB parity RAM, IPC handshaking channels, and ZWT nFBGA (289-ball, 16×16 mm) thermal performance at –40°C to 105°C junction temperature.

Technical Context

The F28M36P63C2ZWTQ implements strict hardware separation between its Master Subsystem (Cortex-M3) and Control Subsystem (C28x), with dedicated buses (AHB/APB vs C28 CPU/DMA), independent voltage regulators (1.2-V digital, 1.8-V analog, 3.3-V I/O), and dual security zones (128-bit password per zone). Interprocessor communication occurs via 32-channel IPC with 2KB message RAM per side and hardware handshaking.

Its analog subsystem integrates two synchronized 12-bit ADCs with 24 total channels, four S/H circuits, and six comparators with integrated 10-bit DACs - all clocked independently from the C28x core to maintain timing integrity during high-speed PWM generation and fault response (e.g., comparator-to-GPIO trip within defined latency).

FAQ

What is the maximum operating junction temperature for the F28M36P63C2ZWTQ?

The F28M36P63C2ZWTQ is rated for a junction temperature range of –40°C to 105°C, as indicated by the 'T' suffix in the part number. This specification is validated per TI's thermal resistance characteristics for the ZWT package (Revision A silicon) and applies under recommended operating conditions with proper PCB thermal design.

Does the F28M36P63C2ZWTQ support pin-compatible replacement with other Concerto devices?

No - the F28M36P63C2ZWTQ is not pin-compatible with F28M36H53B2 or F28M36H33B2 despite sharing the ZWT package, due to differences in peripheral enablement (e.g., ENET/USB presence) and internal signal routing. Pin compatibility is only guaranteed within the P63C2/P53C2 variant group.

How does the IPC mechanism work between the Cortex-M3 and C28x subsystems in the F28M36P63C2ZWTQ?

The F28M36P63C2ZWTQ uses a hardware-managed Interprocessor Communication (IPC) module with 32 handshaking channels and dedicated 2KB message RAM on each side. Channels can generate interrupts, and data transfers occur without CPU intervention - enabling deterministic, low-latency coordination such as passing ADC results from C28x to Cortex-M3 for cloud upload.

Can the F28M36P63C2ZWTQ's dual ADCs operate synchronously for three-phase current measurement?

Yes - the F28M36P63C2ZWTQ's dual 12-bit ADCs support synchronized start triggers via software or PWM events, allowing simultaneous sampling across all 24 channels. This capability is essential for accurate three-phase current reconstruction with minimal inter-channel skew (<1 µs).

What safety features are implemented in the F28M36P63C2ZWTQ for industrial applications?

The F28M36P63C2ZWTQ includes ECC on flash and RAM, parity on RAM, dual security zones with 128-bit passwords, hardware fault trip zones tied to comparators, independent watchdog timers per core, and critical register lock protection - collectively supporting IEC 61508 SIL-2 and ISO 13849 PLd certification efforts in motor control systems.
