产品信息

描述The Delfino™ TMS320F2837xS is a powerful 32-bitfloating-point microcontroller unit (MCU) designed 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 real-time control subsystem is based on TI’s 32-bit C28x floating-point CPU, whichprovides 200 MHz of signal processing performance. The C28x CPU is further boosted bythe new TMU accelerator, which enables fast execution of algorithms with trigonometric operationscommon in transforms and torque loop calculations; and the VCU accelerator, which reduces the timefor complex math operations common in encoded applications. The F2837xS microcontroller family features a CLA real-time control coprocessor. TheCLA is an independent 32-bit floating-point processor that runs at the same speed as the main CPU.The CLA 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 TMS320F2837xS supports up to 1MB (512KW) of onboard flash memory with errorcorrection code (ECC) and up to 164KB (82KW) of SRAM. Two 128-bit secure zones are also availableon the CPU for code protection. Performance analog and control peripherals are also integrated on the F2837xS MCU tofurther enable system consolidation. Four independent 16-bit ADCs provide precise and efficientmanagement of multiple analog signals, which ultimately boosts system throughput. The newsigma-delta filter module (SDFM) works in conjunction with the sigma-delta modulator to enableisolated current shunt measurements. The Comparator Subsystem (CMPSS) with windowed comparatorsallows for protection of power stages when current limit conditions are exceeded or not met. Otheranalog and control peripherals include DACs, PWMs, eCAPs, eQEPs, and other peripherals. Peripherals such as EMIFs, CAN modules(ISO 11898-1/CAN 2.0B-compliant), and a new uPP interface extend theconnectivity of the F2837xS. The uPP interface is a new feature of the C2000™ MCUs and supports high-speed parallel connection to FPGAs or otherprocessors with similar uPP interfaces. Lastly, a USB 2.0 port with MAC and PHY lets users easilyadd universal serial bus (USB) connectivity to their application.特性TMS320C28x 32-Bit CPU200 MHzIEEE 754 Single-Precision Floating-PointUnit (FPU)Trigonometric Math Unit (TMU)Viterbi/ComplexMath Unit (VCU-II)Programmable Control Law Accelerator (CLA)200 MHz IEEE 754 Single-PrecisionFloating-Point InstructionsExecutes Code Independently of MainCPUOn-Chip Memory512KB(256KW) or 1MB (512KW) of Flash (ECC-Protected)132KB (66KW) or 164KB (82KW) ofRAM(ECC-Protected or Parity-Protected)Dual-Zone Security SupportingThird-Party DevelopmentClock and System ControlTwo Internal Zero-Pin 10-MHz OscillatorsOn-ChipCrystal OscillatorWindowed Watchdog Timer ModuleMissingClock Detection Circuitry1.2-V Core, 3.3-V I/O DesignSystem PeripheralsTwo External Memory Interfaces(EMIFs) With ASRAM and SDRAM Support6-Channel Direct Memory Access (DMA)ControllerUp to 169 Individually Programmable, Multiplexed General-PurposeInput/Output (GPIO) Pins With Input FilteringExpanded Peripheral Interrupt Controller(ePIE)Multiple Low-Power Mode (LPM) Support With ExternalWakeupCommunications PeripheralsUSB 2.0 (MAC + PHY)Support for 12-Pin 3.3V-Compatible Universal Parallel Port (uPP) InterfaceTwo Controller AreaNetwork (CAN) Modules (Pin-Bootable)Three High-Speed (up to 50-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 Four Analog-to-Digital Converters (ADCs)16-Bit Mode1.1 MSPS Each (up to 4.4-MSPS System Throughput)Differential InputsUp to 12 External Channels12-Bit Mode3.5 MSPS Each (up to 14-MSPS System Throughput)Single-Ended InputsUp to 24 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)ModulesEight Sigma-Delta Filter Module (SDFM) InputChannels, 2 Parallel Filters per ChannelStandard SDFM Data Filtering Comparator Filter for Fast Action for Out ofRangePackage Options:Lead-Free, Green Packaging337-Ball New FinePitch Ball Grid Array (nFBGA) [ZWT Suffix]176-Pin PowerPAD™ Thermally Enhanced Low-Profile Quad Flatpack (HLQFP)[PTP Suffix]100-Pin PowerPAD ThermallyEnhanced 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.
