Product details
Overview
TMS320F2800137PM from Texas Instruments is a 120-MHz C28x real-time microcontroller with FPU and TMU acceleration, 256KB ECC-protected flash, 36KB ECC/parity-protected RAM, and dual 4-MSPS 12-bit ADCs. It integrates 14 ePWM channels (2 with 150-ps resolution), 1 CAN port, 3 SCI, 2 I2C, 1 SPI, and 38 GPIO for high-precision motor control in power electronics systems.
For engineers reviewing the TMS320F2800137PM datasheet, TMS320F2800137PM pinout, TMS320F2800137PM application, or TMS320F2800137PM equivalent, key selection criteria include real-time signal chain latency, integrated analog-peripheral coupling to PWM, on-chip security (JTAGLOCK, dual-zone), and 64-pin LQFP package compatibility with industrial temperature range (–40°C to 125°C).
Technical Context
The TMS320F2800137PM implements TI's C28x 32-bit DSP core with hardware-accelerated floating-point (FPU32) and trigonometric math (TMU) units, enabling deterministic execution of complex control algorithms. Its dual 12-bit ADCs operate at 4 MSPS with four post-processing blocks per converter and support up to 21 external analog input channels.
Control peripherals include 14 ePWM channels with integrated dead-band generation and hardware trip zones, two eCAP modules, one eQEP module supporting CW/CCW operation, and three CMPSS_LITE comparators with 9.5-bit effective DACs plus one full CMPSS with 12-bit ramp-gen DAC - all tightly coupled to the CPU via crossbar routing for sub-microsecond loop closure.

Does the TMS320F2800137PM include hardware security features?
Yes, the TMS320F2800137PM includes JTAGLOCK to disable debug access, zero-pin boot for secure startup, and dual-zone security that partitions flash and RAM into protected and unprotected regions. These features prevent unauthorized firmware extraction and ensure trusted execution during boot and runtime - critical for industrial and appliance applications requiring IP protection and functional safety compliance.
How many analog-to-digital converter channels does the TMS320F2800137PM support?
The TMS320F2800137PM integrates two independent 12-bit ADCs, each capable of 4 MSPS sampling. Up to 21 external analog input channels are accessible (11 shared with GPIO), with dedicated analog pins A0–A20 and C0–C20. Each ADC includes four post-processing blocks for real-time filtering, offset correction, and windowed comparison - enabling sensor data conditioning without CPU overhead.
What communication interfaces are available on the TMS320F2800137PM?
The TMS320F2800137PM provides one Controller Area Network (CAN) port, three UART-compatible Serial Communication Interfaces (SCI), two Inter-integrated Circuit (I2C) ports, and one Serial Peripheral Interface (SPI) port. All interfaces support pin multiplexing and are accessible on the 64-pin LQFP package. The CAN interface complies with ISO 11898-1 and is commonly used for motor drive coordination and system diagnostics.
Is the TMS320F2800137PM pin-compatible with other devices in the F280013x family?
Yes, the TMS320F2800137PM in the 64-pin PM package is pin-compatible with the TMS320F2800135PM and TMS320F2800133PM in the same package variant. All share identical pin assignments, electrical characteristics, and peripheral mapping - allowing hardware reuse across different memory/security configurations. However, the TMS320F2800132 uses only 48- and 32-pin packages and is not pin-compatible with the 64-pin variants.
