描述The TMS320F2807x microcontroller platform is part of the Piccolo™ family and is suited for advanced closed-loop control applicationssuch asindustrialdrives and servo motor control;solarinverters and converters;digitalpower;transportation;andpowerline communications. Complete development packages for digital power and industrial drivesare available as part of the powerSUITE andDesignDRIVE initiatives. The F2807x is a 32-bit floating-point microcontroller based on TI’s industry-leadingC28x core. This core is boosted by the trigonometric hardware accelerator which improvesperformance of trigonometric-based algorithms with CPU instructions such as sine, cosine, andarctangent functions, which are common in torque-loop and position calculations. The F2807x microcontroller family features a CLA real-time control coprocessor. The CLAis an independent 32-bit floating-point processor that runs at the same speed as the main CPU. TheCLA responds to peripheral triggers and executes code concurrently with the main C28x CPU. Thisparallel processing capability can effectively double the computational performance of a real-timecontrol system. By using the CLA to service time-critical functions, the main C28x CPU is free toperform other tasks, such as communications and diagnostics.The F2807x device supports up to 512KB (256KW) of ECC-protected onboard flash memoryand up to 100KB (50KW) of SRAM with parity. Two independent security zones are also available for128-bit code protection of the main C28x.The analog subsystem boasts up to three 12-bit ADCs, which enable simultaneousmanagement of three independent power phases, and up to eight windowed comparator subsystems(CMPSSs), allowing very fast, direct trip of the PWMs in overvoltage or overcurrent conditions. Inaddition, the device has three 12-bit DACs, and precision control peripherals such as enhancedpulse width modulators (ePWMs) with fault protection, eQEP peripherals, and eCAP units.Connectivity peripherals such as dual Controller Area Network (CAN) modules(ISO 11898-1/CAN 2.0B-compliant) and a USB 2.0 port with MAC andfull-speed PHY let users add universal serial bus (USB) connectivity to their application.特性TMS320C28x 32-Bit CPU120 MHzIEEE 754 Single-Precision Floating-PointUnit (FPU)Trigonometric Math Unit(TMU)Programmable Control Law Accelerator (CLA)120 MHzIEEE 754 Single-Precision Floating-PointInstructionsExecutes Code Independently of MainCPUOn-Chip Memory512KB(256KW) of Flash (ECC-Protected)100KB (50KW) of RAM (ECC-Protected orParity-Protected)Dual-Zone Security Supporting Third-PartyDevelopmentClock and System ControlTwo Internal Zero-Pin 10-MHz OscillatorsOn-ChipCrystal OscillatorWindowed Watchdog Timer ModuleMissingClock Detection Circuitry3.3-V I/O With Available Internal Voltage Regulator for 1.2-V Core SupplySystem PeripheralsExternal Memory Interface (EMIF) With ASRAM and SDRAMSupport6-Channel Direct Memory Access (DMA) ControllerUpto 97 Individually Programmable, Multiplexed General-Purpose Input/Output (GPIO) Pins With InputFilteringExpanded Peripheral Interrupt Controller(ePIE)Multiple Low-Power Mode (LPM) Support With ExternalWakeupCommunications PeripheralsUSB 2.0 (MAC + PHY)Two Controller Area Network(CAN) Modules (Pin-Bootable)Three High-Speed (up to 30-MHz) SPI Ports(Pin-Bootable)Two Multichannel Buffered Serial Ports(McBSPs)Four Serial Communications Interfaces (SCI/UART)(Pin-Bootable)Two I2C Interfaces(Pin-Bootable)Analog SubsystemUp to Three Analog-to-Digital Converters (ADCs)12-Bit Mode3.1 MSPS Each (up to 9.3-MSPS System Throughput)Single-Ended InputsUp to 17 External ChannelsSingle Sample-and-Hold (S/H) on EachADCHardware-Integrated Post-Processing of ADCConversionsSaturating Offset CalibrationError From Setpoint CalculationHigh, Low, and Zero-Crossing Compare, With Interrupt CapabilityTrigger-to-Sample Delay CaptureEight WindowedComparators With 12-Bit Digital-to-Analog Converter (DAC) ReferencesThree12-Bit Buffered DAC OutputsEnhanced Control Peripherals24 PWM Channels With Enhanced Features16High-Resolution Pulse Width Modulator (HRPWM) ChannelsHigh Resolution onBoth A and B Channels of 8 PWM ModulesDead-Band Support (on BothStandard and High Resolution)Six Enhanced Capture(eCAP) ModulesThree Enhanced Quadrature Encoder Pulse (eQEP)ModulesUp to Eight Sigma-Delta Filter Module (SDFM) Input Channels,2 Parallel Filters per ChannelStandard SDFM Data Filtering Comparator Filter for Fast Action for Out ofRangePackage Options:176-Pin PowerPAD™ ThermallyEnhanced Low-Profile Quad Flatpack (HLQFP) [PTP Suffix]100-Pin PowerPADThermally Enhanced Thin Quad Flatpack (HTQFP) [PZPSuffix]Temperature Options:T: –40ºC to 105ºC JunctionS: –40ºC to125ºC JunctionQ: –40ºC to 125ºC Free-Air(AEC Q100 Qualification for AutomotiveApplications) All trademarks are the property of their respective owners.
