Texas Instruments F28M36P53C2ZWTS

Overview

F28M36P53C2ZWTS 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 512KB ECC flash in the control subsystem, 1MB ECC flash in the master subsystem, dual 12-bit ADCs (2.88 MSPS), six comparators with integrated DACs, and 289-ball nFBGA (ZWT) packaging rated for –40°C to 125°C junction temperature - deployed in solar string inverters and servo drive control modules.

For engineers reviewing the F28M36P53C2ZWTS datasheet, F28M36P53C2ZWTS pinout, F28M36P53C2ZWTS application, or F28M36P53C2ZWTS equivalent, key selection criteria include dual-core clock coordination (125/150 MHz), shared 64KB parity RAM, IPC message RAM for interprocessor communication, Ethernet 1588 MII support, and HRPWM capability across 16 outputs - all critical for deterministic industrial motion control and grid-tied power conversion.

Technical Context

The F28M36P53C2ZWTS implements a tightly coupled dual-subsystem architecture: the master subsystem runs at up to 125 MHz with USB-OTG + PHY, 10/100 ENET 1588 MII, five UARTs, four SSIs, two I²Cs, and two D_CAN modules; the control subsystem operates at up to 150 MHz with IEEE-754 FPU, VCU accelerator, 12 ePWM modules (24 outputs, 16 high-resolution), six eCAP, three eQEP, and McBSP - both sharing dual 12-bit ADCs and six comparator+DAC units.

Clocking is managed via independent PLLs with dynamic ratio changes; safety features include ECC on flash/RAM, parity on RAM, dual security zones (128-bit password per zone), NMI watchdogs for both cores, and critical register lock protection - enabling compliance with industrial functional safety requirements without external supervision circuitry.

FAQ

What is the maximum operating junction temperature for F28M36P53C2ZWTS?

The F28M36P53C2ZWTS is rated for –40°C to 125°C junction temperature (S-grade), validated per TI's thermal resistance characterization for ZWT package Revision A silicon - enabling deployment in high-ambient industrial enclosures without forced air cooling.

Does F28M36P53C2ZWTS support IEEE 1588 Precision Time Protocol?

Yes, the F28M36P53C2ZWTS includes a full 10/100 ENET 1588 MII interface in its master subsystem, with hardware timestamping support in the EMAC peripheral - enabling sub-microsecond clock synchronization for distributed solar inverters and industrial automation networks.

How many high-resolution PWM outputs does F28M36P53C2ZWTS provide?

The F28M36P53C2ZWTS provides 16 high-resolution PWM outputs across its 12 ePWM modules - each capable of 150-ps resolution and independent dead-time insertion - meeting stringent timing requirements for SiC and GaN power stages in high-frequency inverters.

Can F28M36P53C2ZWTS execute code from both master and control subsystem flash simultaneously?

Yes, the F28M36P53C2ZWTS supports concurrent execution: the Arm Cortex-M3 core fetches from its dedicated 1MB ECC flash, while the C28x core executes from its separate 512KB ECC flash - with no bus contention due to independent instruction buses and memory controllers.

What analog peripherals are shared between the two cores in F28M36P53C2ZWTS?

The dual 12-bit ADCs, six comparators with integrated DACs, and four sample-and-hold circuits are shared resources accessible by both the Cortex-M3 and C28x subsystems - coordinated via the analog common interface bus with priority arbitration to prevent access conflicts during real-time control loops.
