Product details
Overview
TMS320F2800133RHBR from Texas Instruments is a 120-MHz C28x real-time microcontroller with FPU and TMU acceleration, 64KB flash, 36KB RAM (ECC/parity-protected), and integrated analog peripherals including two 4-MSPS 12-bit ADCs and 14 ePWM channels - used in BLDC motor control for cordless power tools and AC-DC power supplies.
For engineers reviewing the TMS320F2800133RHBR datasheet, TMS320F2800133RHBR pinout, TMS320F2800133RHBR application, or TMS320F2800133RHBR equivalent, key selection criteria include its 32-pin VQFN (RHB) package, 120-MHz deterministic signal-chain performance, dual-zone security, CAN interface, and support for high-resolution PWM (150-ps) in compact industrial motor drives.
Technical Context
The TMS320F2800133RHBR implements TI's C28x 32-bit DSP core with hardware-accelerated floating-point (FPU32) and trigonometric math (TMU) units, enabling sub-microsecond loop closure in digital power and motor control. Its real-time subsystem tightly couples ADC sampling, PWM generation, and comparator subsystems (CMPSS + CMPSS_LITE) for synchronized feedback processing.
It integrates dual 4-MSPS 12-bit ADCs with four post-processing blocks (PPB) per ADC, three windowed comparators with 9.5-bit DACs, and 14 ePWM channels - two with 150-ps high-resolution capability - all operating under deterministic latency constraints defined by the ePIE interrupt controller and DCC clock monitoring.

FAQ
What is the maximum operating frequency of the TMS320F2800133RHBR CPU?
The TMS320F2800133RHBR features a C28x 32-bit DSP core rated at 120 MHz - delivering deterministic instruction execution and sub-microsecond interrupt latency. This frequency is fully supported across the full –40°C to 125°C ambient temperature range and is validated in TI's production test flow. The TMS320F2800133RHBR does not support overclocking beyond 120 MHz.
Does the TMS320F2800133RHBR include hardware security features?
Yes, the TMS320F2800133RHBR includes dual-zone security, JTAGLOCK to disable debug access, and zero-pin boot mode - all implemented in silicon with dedicated security ROM. These features prevent unauthorized firmware readout and enforce secure boot policies without external crypto elements. Security configuration is persistent and survives power cycles.
How many ADC channels are accessible on the TMS320F2800133RHBR in the 32-pin RHB package?
The TMS320F2800133RHBR supports up to 21 external ADC input channels, but in the 32-pin RHB package, 11 analog-capable pins are shared with GPIO functions (A0–A16, C0–C19). Pin multiplexing allows configuration of up to 11 dedicated analog inputs plus internal temperature sensor - confirmed in Section 5.5 of the SPRSP63B datasheet.
What communication interfaces are available on the TMS320F2800133RHBR?
The TMS320F2800133RHBR integrates one CAN port (CAN/DCAN), two I²C interfaces, three UART-compatible SCI modules, and one SPI port - all accessible on the 32-pin RHB package. Pin allocation for these interfaces is documented in Figure 5-5 and Table 5-1 of the datasheet, with no functional reduction versus larger packages.
Is the TMS320F2800133RHBR pin-compatible with other devices in the F280013x family?
No - the TMS320F2800133RHBR uses the 32-pin RHB VQFN package, while other F280013x variants use 48-pin (RGZ/PT) or 64-pin (PM/VPM) packages. Pin mapping differs across packages; for example, ePWM1A appears on pin 27 in RHB but on pin 42 in RGZ. Migration requires PCB redesign and signal reassignment per TI's pin multiplexing tables.
