Texas Instruments F28M36P53C2ZWTQ

Overview

F28M36P53C2ZWTQ from Texas Instruments is a dual-core Concerto™ microcontroller integrating an Arm® Cortex®-M3 (125 MHz) and TMS320C28x (150 MHz) real-time control CPU on a single die, with 512 KB ECC flash in the control subsystem, 1024 KB ECC flash in the master subsystem, and dual 12-bit ADCs delivering up to 2.88 MSPS for industrial motor drive feedback loops.

For engineers reviewing the F28M36P53C2ZWTQ datasheet, F28M36P53C2ZWTQ pinout, F28M36P53C2ZWTQ application, or F28M36P53C2ZWTQ equivalent, this page delivers verified core frequencies, memory partitioning, analog subsystem specs, IPC architecture, and confirmed ZWT nFBGA package details - all extracted from TI's SPRS825F production data sheet (June 2020 revision).

Technical Context

The F28M36P53C2ZWTQ implements strict hardware separation between its master (Cortex-M3) and control (C28x) subsystems via dedicated buses, shared RAM (64 KB parity), and a 32-channel interprocessor communication (IPC) system with handshaking and interrupt-capable channels. Clock domains are independently configurable with dynamic PLL ratio changes supported for both cores.

Its analog subsystem integrates two synchronized 12-bit ADCs (24 total channels, 347 ns conversion time), six comparators with integrated 10-bit DACs, and four sample-and-hold circuits - all referenced to dedicated VDDA/VSSA rails and designed for closed-loop timing-critical sampling in servo and inverter applications.

FAQ

What is the maximum operating frequency of each CPU core in the F28M36P53C2ZWTQ?

The F28M36P53C2ZWTQ features an Arm Cortex-M3 core rated at 125 MHz and a TMS320C28x core rated at 150 MHz. These frequencies are achievable simultaneously only when clock dividers are configured per Table 3-2 in the SPRS825F datasheet; for example, 125 MHz Cortex-M3 requires C28x ≤125 MHz, while full 150 MHz C28x operation limits Cortex-M3 to 75 MHz. All configurations maintain full peripheral functionality.

Does the F28M36P53C2ZWTQ include hardware security features for firmware protection?

Yes, the F28M36P53C2ZWTQ includes dual security zones (128-bit password per zone) for the master subsystem and one security zone for the control subsystem. It also supports ECC on flash and RAM, parity on shared RAM, and critical register lock protection - features documented in TI's safety manual and used to support IEC 61508 SIL-2 certification efforts in industrial drive applications.

How many analog-to-digital converter channels does the F28M36P53C2ZWTQ support, and what is their timing performance?

The F28M36P53C2ZWTQ integrates two independent 12-bit ADC modules, each with 12 input channels (24 total), four sample-and-hold circuits, and a maximum aggregate sampling rate of 2.88 MSPS. Each conversion completes in 347 ns, and both ADCs can be triggered synchronously - enabling precise, time-aligned current and voltage measurements critical for vector control in motor drives.

Is the F28M36P53C2ZWTQ pin-compatible with other devices in the F28M36x family?

Yes, the F28M36P53C2ZWTQ shares the identical 289-ball ZWT nFBGA package, pinout, and ball assignment with F28M36P63C2ZWT, F28M36H53B2ZWT, and F28M36H33B2ZWT. This allows direct PCB footprint reuse across variants - differences are internal (flash size, Ethernet/USB inclusion) and require only firmware and configuration updates, not hardware redesign.

What communication interfaces are available on the F28M36P53C2ZWTQ for industrial networking?

The F28M36P53C2ZWTQ provides 10/100 ENET 1588 MII with hardware timestamping, two D_CAN modules (CAN 2.0B compliant), five UARTs, four SSI/SPI ports, two I²C interfaces, and USB OTG with integrated PHY. These interfaces support industrial protocols including EtherNet/IP, Modbus TCP, CANopen, and USB device/host modes - all accessible concurrently via the dual-core architecture without resource contention.
