F280045PMSR - C2000 32-bit MCU, 100MHz, 256KB Flash | TI
MPN: F280045PMSR ✓ Hoạt độngF280045PMSR Tóm tắt
A microcontroller (MCU) is a programmable processor that integrates a CPU core, memory (Flash and RAM), and peripherals into a single silicon die. The C2000 family sits inside the broader microcontroller taxonomy as MCU -> 32-bit MCU -> DSP-enhanced MCU -> real-time control MCU, and is purpose-built for digital power conversion, motor control, and signal-conditioning applications where deterministic, sub-microsecond interrupt response is required.
Key features include 256 KB (256K x 8) of flash, 100 KB of RAM, fourteen 12-bit ADC channels, two 12-bit DAC outputs, three on-chip programmable gain amplifiers (PGAs), and a Sigma-Delta Filter Module (SDFM) for isolated current/voltage sensing. Communication peripherals include SPI, SCI/UART, I2C, CAN, and LIN. The 1.14 V to 1.32 V core supply is generated internally from a 3.3 V rail via an integrated voltage regulator.
The architecture pairs a Harvard-style bus with a tightly coupled control-law accelerator (CLA) and the FPU/TMU pair, executing trigonometric and matrix operations in hardware. This reduces software loop latency versus a software-emulated math approach, allowing higher switching frequencies in digital power supplies.
Typical applications include digital totem-pole PFC converters, solar inverters, server/telecom SMPS, industrial motor drives, traction inverters, EV charging stations, and battery management systems. The SDFM and PGA blocks particularly benefit isolated shunt-based current sensing in high-voltage systems.
When designing with this device, ensure the 3.3 V supply is decoupled with at least one 1 µF and one 100 nF ceramic capacitor near each VDDS pin, and follow TI's SPRS942 layout guidelines for the LQFP PM package to keep digital return currents out of the analog ground domain.

Ứng dụng tiêu biểu
F280045PMSR phù hợp cho 7 Áp dụngs: Digital Totem-Pole PFC Converter, Solar String Inverter Control, Industrial Servo Motor Drive, Onboard EV Charger, Server / Telecom SMPS, Battery Management System (BMS) Master Controller, Industrial Variable Frequency Drive (VFD).
Digital Totem-Pole PFC Converter
The F280045PMSR's 100 MHz C28x CPU with FPU and TMU executes voltage-loop and current-loop control math at sub-microsecond intervals, making it well-suited to bridgeless totem-pole PFC stages operating above 100 kHz switching frequency. Its 14 12-bit ADC channels sample input voltage, input current, output voltage, and auxiliary signals simultaneously, while the integrated PGAs amplify low-amplitude shunt signals directly at the chip pins to minimize analog noise. The 256 KB flash holds full control firmware, including state machines for AC line cycle management and soft-start routines. Compared with discrete analog PFC controllers, this MCU enables digital soft-start, adaptive dead-time control, and on-the-fly efficiency tuning.
Được đề xuất
Solar String Inverter Control
In string inverter designs, the F280045PMSR orchestrates MPPT, grid synchronization, and anti-islanding algorithms with deterministic interrupt latency from its C28x core. The on-chip SDFM accepts isolated delta-sigma modulator outputs from high-voltage current transducers, eliminating optocoupler-based analog isolation paths and improving noise immunity. With 256 KB flash, the MCU holds grid-code lookup tables for multiple regional standards and supports firmware-over-the-air updates for field configuration changes. The integrated PGAs condition shunt currents up to ±5 A directly, supporting strings from 5 kW to 30 kW without external amplifiers.
Được đề xuất
Industrial Servo Motor Drive
Field-oriented control (FOC) of permanent magnet servo motors requires sin/cos trigonometric operations at every PWM cycle, which the F280045PMSR's TMU executes in hardware cycles rather than software loops. The 14 ADC channels handle three-phase currents, DC bus voltage, and resolver/external encoder inputs for rotor position feedback. FOC torque loops execute at 20-40 kHz thanks to the 100 MHz CPU with FPU, while speed and position loops run at lower rates from the same firmware. Industrial servo designers benefit from TI's InstaSPIN™ libraries ported to this C2000 family for sensorless control starting from standstill.
Được đề xuất
Onboard EV Charger
Level-2 onboard EV chargers (typically 6.6 kW to 22 kW) require PFC plus isolated DC-DC conversion, both controlled by a single C2000 MCU such as the F280045PMSR. The integrated PGAs and SDFM accept signals from isolated current sensors for AC and DC sides simultaneously, while 256 KB of flash holds PFC state machine, LLC resonant converter control, and CAN communication stack for vehicle handshake. Hardware FPU/TMU accelerates the resonant converter math for variable-frequency, variable-pulse-frequency control schemes, achieving peak efficiencies above 96% across the operating range.
Được đề xuất
Server / Telecom SMPS
Digital-controlled server and telecom power supplies (typically 80 PLUS Titanium efficiency targets) use the F280045PMSR to implement LLC or phase-shift full-bridge topologies with adaptive dead-time and burst-mode optimization. The 14 ADC channels monitor primary currents, secondary currents via SDFM, and multiple output voltage rails for tight regulation under dynamic load steps. With 256 KB flash and 100 KB RAM, the MCU can run TI's Digital Power SDK with state-machine-based firmware, supporting firmware customization for OEM-specific telemetry and PMBus commands.
Được đề xuất
Battery Management System (BMS) Master Controller
In a hierarchical BMS, the F280045PMSR acts as the master controller coordinating cell-balancing, state-of-charge estimation, and CAN communication to the vehicle or grid BMS. The SDFM inputs accept isolated voltage and current measurements from high-voltage battery stacks, while the integrated PGAs handle sub-mV signal conditioning directly. Hardware FPU accelerates the Kalman filter math required for accurate SoC and SoH estimation, running at 100 MHz with deterministic cycle time. The 256 KB flash supports multiple battery chemistry profiles stored onboard, with PMBus/SMBus for charger interface compatibility.
Được đề xuất
Industrial Variable Frequency Drive (VFD)
Three-phase industrial motor drives from 1 kW to 15 kW use the F280045PMSR as the main control MCU for FOC, scalar V/Hz, and direct torque control modes. The 100 MHz C28x with FPU executes FOC loops at 10-20 kHz, while speed and position loops operate at slower rates from the same interrupt structure. The 14 ADC inputs handle three-phase currents, DC bus voltage, and motor temperature feedback with simultaneous sampling, eliminating timing skew artifacts. Communication peripherals include CAN, SPI, SCI/UART for integration with factory automation networks.

Ghi chú thiết kế
The F280045PMSR requires a single 3.3 V supply on VDDS pins; the internal voltage regulator generates the 1.2 V core rail from this input. Place at minimum one 1 µF X7R ceramic capacitor and one 100 nF X7R ceramic capacitor close to each VDDS pin, plus a bulk 10 µF tantalum or ceramic near the IC. Inadequate decoupling can cause core-voltage droop during high-speed ADC sampling, leading to ADC accuracy errors and CPU lockups under heavy switching noise.
Follow TI's SPRS942 PCB layout guidelines for the LQFP (PM) package: place a continuous ground plane on layer 2, route analog and digital signals on separate layers with via stitching around analog islands, and keep ADC traces short and symmetrically routed to minimize channel-to-channel skew. The exposed thermal pad on the LQFP-64 PM package should be soldered to a copper pour with at least 8 thermal vias to the internal ground plane for heat dissipation.
Estimated: ADC input impedance is approximately 3.3 kΩ per channel; designers must ensure external source impedance stays below 1 kΩ to avoid ADC sample-and-hold errors, or add an external buffer op-amp. The PGA inputs are differential and require common-mode voltages within the 0-3.3 V supply range; exceeding this can permanently damage the PGA inputs. When using the SDFM, verify that the external delta-sigma modulator clock frequency matches the F280045PMSR's expected range (10-20 MHz typical).
