Product details
Overview
TMS320F280023PNQR from Texas Instruments is a C28x-based real-time microcontroller designed for high-efficiency power electronics control, featuring a 100MHz DSP core with IEEE 754 FPU, 64KB ECC-protected flash, 24KB RAM (ECC/parity), and 43 GPIOs. It integrates dual 3.45MSPS 12-bit ADCs, 14 ePWM channels (8 with 150ps resolution), 4 windowed comparators, and FSI up to 200Mbps - deployed in solar inverters, EV charging power modules, and industrial motor drives.
For engineers reviewing the TMS320F280023PNQR datasheet, TMS320F280023PNQR pinout, TMS320F280023PNQR application, or TMS320F280023PNQR equivalent, key selection criteria include its AEC-Q100 qualified Q-temp grade (–40°C to 125°C free-air), 80-pin LQFP package, CLB-free configuration, and support for GaN/SiC gate drive timing precision in closed-loop power conversion systems.
Technical Context
The TMS320F280023PNQR implements a deterministic C28x CPU with hardware-accelerated math units (TMU, VCRC, FINTDIV) enabling sub-microsecond execution of NLPID, trigonometric, and CRC-intensive control loops. Its analog subsystem tightly couples dual ADCs with four CMPSS modules and post-processing blocks for real-time voltage/current fault detection and waveform shaping.
Control peripherals include 14 ePWM channels with integrated dead-band generation and hardware trip zones, three eCAP modules (one with HRCAP), two eQEP interfaces, and a Host Interface Controller (HIC) for external host access to internal memory - all synchronized via a shared XBAR routing matrix and ERAD debugging infrastructure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | C28x 32-bit DSP at 100MHz with IEEE 754 FPU and TMU - enables floating-point motor control algorithms without software emulation overhead. |
| Flash Memory | 64KB (32KW) ECC-protected - supports secure firmware updates and runtime error correction in safety-critical power stages. |
| RAM | 24KB (12KW) total: 20KB dedicated/local + 4KB global shared - sufficient for dual-buffered PWM buffers, ADC result arrays, and real-time PID coefficient tables. |
| ADC Performance | Dual 12-bit, 3.45MSPS converters with 16 external channels and 4 PPBs per ADC - allows simultaneous sampling of phase currents and DC-link voltage with on-the-fly filtering and threshold comparison. |
| ePWM Capability | 14 channels, 8 with 150ps high-resolution mode - delivers precise gate timing for SiC/GaN half-bridges and multilevel topologies with <1ns jitter. |
| Package & Temp | 80-pin LQFP (PN), –40°C to 125°C free-air (Q-grade) - AEC-Q100 qualified for automotive EV charging and onboard charger applications. |

Pinout & Package
80-pin Low-profile Quad Flatpack (LQFP), 14mm × 14mm body size, 0.5mm pitch. RoHS-compliant, lead-free finish. Thermal resistance θJA = 36.2°C/W (JEDEC Std 2S2P board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDIO, VDDA | Power supply rails | VDD (3.3V core), VDDIO (3.3V I/O), VDDA (3.3V analog) - require separate low-noise decoupling; VDDA must be filtered for ADC/CMPSS reference stability. |
| VSS, VSSA | Ground returns | Digital ground (VSS) and analog ground (VSSA) - must be connected at single point near device to minimize ADC noise coupling. |
| XRSn | Reset input | Active-low asynchronous reset - asserted during power-on, brownout, or watchdog timeout; debounced externally for robust system recovery. |
| GPIO0–GPIO46 | Configurable I/O | 43 multiplexed GPIOs - support peripheral functions including ePWM, eCAP, eQEP, SPI, I²C, and analog inputs (A0–A15, C0–C15). |
| FLT1, FLT2 | Fault inputs | Dedicated hardware trip zone inputs - trigger immediate ePWM shutdown within <100ns for overcurrent/overvoltage protection. |
| VREFHI/VREFLO | ADC reference | External 3.3V reference inputs - define full-scale range for both ADCs; internal 1.65V reference available when unused. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware Trip Zones (TZ) | Eight configurable TZ inputs (including FLT1/FLT2) enable sub-100ns ePWM shutdown - critical for protecting SiC/GaN switches during short-circuit events. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280023C-Q1 | Includes 2 CLB tiles and motor control ROM libraries; identical pinout and memory map. | Required where FPGA-like logic offload (e.g., custom encoder interpolation or PWM pattern sequencing) is needed alongside motor control. | Select F280023C-Q1 only if CLB functionality is actively used; otherwise F280023PNQR offers lower cost and same core control performance. |
| TMS320F280025-Q1 | 128KB flash (vs. 64KB), same peripherals and package - no CLB. | Suitable for larger firmware images (e.g., dual-bank OTA updates, extended diagnostics, or multi-protocol stacks). | Choose F280025-Q1 when firmware size exceeds 512KB or when future feature expansion requires headroom beyond current 64KB allocation. |
Compared with TMS320F280023C-Q1, the TMS320F280023PNQR omits CLB logic but retains identical analog/peripheral timing specs and AEC-Q100 qualification - making it optimal for cost-sensitive, CLB-free power control.

FAQ
What is the maximum operating frequency of the C28x CPU in the TMS320F280023PNQR?
The TMS320F280023PNQR features a C28x 32-bit DSP core running at 100MHz - delivering deterministic real-time performance for floating-point and fixed-point control algorithms. This clock speed is achieved using an internal PLL with crystal or external clock input, and is fully supported across the –40°C to 125°C free-air temperature range specified for the TMS320F280023PNQR.
Does the TMS320F280023PNQR include Configurable Logic Block (CLB) resources?
No, the TMS320F280023PNQR does not include CLB resources. CLB functionality is exclusive to the 'C' variants (e.g., TMS320F280023C-Q1). The TMS320F280023PNQR is the base variant with full C28x, analog, and control peripheral capabilities - identical pinout and memory map - but without CLB tiles, making it optimized for cost-sensitive applications where FPGA-like logic extension is unnecessary.
What are the key differences between TMS320F280023PNQR and TMS320F280025-Q1?
The TMS320F280023PNQR and TMS320F280025-Q1 share identical peripherals, package options, and AEC-Q100 qualification, but differ in flash capacity: TMS320F280023PNQR has 64KB ECC-protected flash, while TMS320F280025-Q1 provides 128KB. Both use the same C28x 100MHz core and support identical real-time control workloads - the choice depends on firmware size requirements and future scalability needs for the TMS320F280023PNQR design.
Which analog inputs are available on the TMS320F280023PNQR in the 80-pin LQFP package?
In the 80-pin LQFP (PN) package, the TMS320F280023PNQR supports up to 16 external analog input channels - mapped across pins A0–A15 and C0–C15. These are shared with GPIO functions and can be configured via the Input XBAR. Additionally, eight of these analog-capable pins (AIO224–AIO242) support digital input mode, enabling flexible mixed-signal signal routing without external multiplexers for the TMS320F280023PNQR.
Is the TMS320F280023PNQR qualified for automotive applications?
Yes, the TMS320F280023PNQR carries the 'Q' suffix indicating AEC-Q100 qualification for automotive applications, with a specified operating temperature range of –40°C to 125°C free-air. It includes functional safety documentation supporting ISO 26262 system-level development and integrates hardware diagnostic features such as MPOST, HWBIST, and windowed watchdog timers - all validated for use in automotive on-board chargers, DC-DC converters, and EPS modules.
