Texas Instruments F2800132RHBR

Overview

F2800132RHBR from Texas Instruments is a 100-MHz C28x real-time microcontroller optimized for power electronics control, featuring 64KB flash, 36KB ECC/parity-protected RAM, dual 12-bit 4-MSPS ADCs, 14 ePWM channels (2 with 150-ps resolution), and integrated CMPSS/CMPSS_LITE comparators - deployed in AC-DC converters, BLDC motor drives, and solar charge controllers.

For engineers reviewing the F2800132RHBR datasheet, F2800132RHBR pinout, F2800132RHBR application, or F2800132RHBR equivalent, key selection criteria include its 100-MHz deterministic C28x DSP core, on-chip analog signal chain integration (ADC + comparators + post-processing), 32-pin VQFN package with 38 GPIO (11 shared analog), and support for closed-loop stepper, servo drive control, and UPS power stage management.

Technical Context

The F2800132RHBR implements TI's C28x 32-bit DSP CPU at 100 MHz with no FPU or TMU - distinguishing it from higher-tier F280013x variants - and relies on fixed-point arithmetic for deterministic real-time control. Its analog subsystem includes two independent 12-bit ADCs with four post-processing blocks each and three windowed comparators (CMPSS_LITE) with 9.5-bit effective DACs.

System-level timing is managed via dual internal 10-MHz oscillators, crystal/external clock input, and a windowed watchdog timer; communication is supported by one CAN port, two I2C interfaces, three UART-compatible SCI ports, and one SPI port - all accessible within the 32-pin RHB footprint through pin multiplexing.

FAQ

What is the maximum operating frequency of the F2800132RHBR CPU core?

The F2800132RHBR features a C28x 32-bit DSP CPU core rated at 100 MHz - confirmed in the Device Comparison table and Section 4.1 of the SPRSP63B datasheet. This frequency is fixed and does not scale with voltage or temperature; it provides deterministic instruction timing for hard real-time control loops in motor drives and power converters. The F2800132RHBR does not include an FPU or TMU, unlike higher-tier variants such as the F2800133RHBR.

Does the F2800132RHBR support CAN communication?

Yes, the F2800132RHBR includes one Controller Area Network (CAN/DCAN) bus port - explicitly listed under "Communications peripherals" in Section 1 Features and verified in Table 4-1 (Device Comparison). This CAN interface complies with ISO 11898-1 and supports bit rates up to 1 Mbps, enabling robust communication in industrial motor control networks and UPS system monitoring. The CAN peripheral is accessible on dedicated pins in the 32-pin RHB package.

How many analog-to-digital converter (ADC) channels does the F2800132RHBR support?

The F2800132RHBR integrates two independent 12-bit ADCs, each capable of 4-MSPS conversion rate, with up to 21 external input channels - 11 of which are shared with GPIO pins. As documented in Section 1 and Table 4-1, this configuration supports simultaneous sampling across multiple sensors in power electronics applications. The ADCs include four post-processing blocks (PPB) each for hardware-based filtering, offset correction, and averaging - reducing CPU overhead in real-time control tasks.

What package type and pin count does the F2800132RHBR use?

The F2800132RHBR uses a 32-pin Very Thin Quad Flatpack No Lead (VQFN) package, designated RHB suffix, with a 5 mm × 5 mm body size and 0.5-mm pitch. This is confirmed in the Package Information table and Device Comparison section of the SPRSP63B datasheet. The RHB package provides thermal performance suitable for industrial ambient temperatures (–40°C to 125°C) and enables compact PCB layouts in space-constrained power modules where the F2800132RHBR is commonly deployed.

Is the F2800132RHBR pin-compatible with other devices in the F280013x family?

No, the F2800132RHBR is not pin-compatible with larger-package variants (e.g., PT, RGZ, PM) due to differing pin counts and signal allocations. However, within the 32-pin RHB footprint, the F2800132RHBR shares identical pinout with F2800133RHBR, F2800135RHBR, and F2800137RHBR - as shown in Figure 5-5 and validated in Section 5.1. Signal functionality may differ (e.g., missing FPU/TMU in F2800132RHBR), but physical layout and solder footprint are identical across RHB-suffixed devices.
