Microchip推出新型8位单片机，集成独立于内核的外设，缩短了CAN网络关键系统事件的响应时间

Microchip Technology Inc.(美国微芯科技公司)日前宣布，PIC18系列产品线又新增了两款8位单片机(MCU)产品。这些单片机将控制器区域网(CAN)总线与大量独立于内核的外设(CIP)结合使用，不但增强了系统功能，而且，设计人员不需要增加复杂的软件，便能够更轻松地开发基于CAN的应用。关于这两款新型PIC18 K83器件的详细信息，请访问：www.microchip.com/k83。

在基于CAN的系统中使用K83 MCU的一个关键优点是，CIP为实时事件提供了确定性响应，缩短了设计时间，并且可以采用MPLAB®代码配置器(MCC)工具方便地进行配置。这一新系列产品非常适合医疗、工业和汽车市场中使用CAN的应用，例如电动手术台、资产追踪、超声机、自动输送机和汽车配件等。在完成一项任务时，与编写并验证整个软件例程相比，系统设计人员配置基于硬件的外设要容易得多，从而可以节省大量的时间。

Microchip的8位MCU产品部副总裁Steve Drehobl表示：“在MCC中点击几个按键便能够配置好MCU，这将改变您设计CAN的方式。采用与其他PIC®单片机同样的工具，利用 K83系列的CIP，即可方便地使用通信、智能模拟和低功耗等特性。”

PIC18 K83器件中15个节省时间的CIP包括：支持内存扫描的循环冗余校验(CRC)，以确保非易失性存储器的完整性;直接存储器访问(DMA)，实现存储器与外设之间的数据传输，不需要CPU参与;窗口看门狗定时器(WWDT)，用于触发系统复位;具有计算功能的12位模数转换器(ADC2)，支持自动模拟信号分析，实现了实时系统响应;互补波形发生器(CWG)，支持电机控制的高效率同步切换。如需了解详情或其他CIP，请访问我们的8位MCU设计中心。

PIC18F K83 Product Family

8-Bit MCUs That Combine CAN

and Core Independent Peripherals

The PIC18 K83 family continues our longstanding tradition of innovation in 8-bit MCUs by combining an extensive array of Core Independent Peripherals (CIPs) with the PIC18 CAN product line. These cost-optimized MCUs contain 15 time-saving CIPs in 28-pins with up to 64 KB of flash memory. These products are ideal for applications using CAN in the medical, industrial and automotive markets, such as motorized surgical tables, asset tracking, ultrasound machines, automated conveyors and automotive accessories. System designers can benefit greatly by saving time, as it is significantly easier to configure a hardware-based peripheral, as opposed to writing and validating an entire software routine to accomplish a task. The devices include a full complement of Core Independent Peripherals including Cyclic Redundancy Check (CRC) with memory scan for ensuring the integrity of non-volatile memory; Direct Memory Access (DMA) enabling data transfers between memory and peripherals without CPU involvement; Windowed Watchdog Timer (WWDT) for triggering system resets; 12-bit Analog-to-Digital Converter with Computation (ADC2) for automating analog signal analysis for real-time system response; and Complementary Waveform Generator (CWG) for enabling high-efficiency synchronous switching for motor control.

Intelligent Analog

The products offer intelligent analog peripherals including Zero Cross Detect (ZCD), on-chip comparator, and a 12-bit ADC with Computation (ADC2) automating Capacitive Voltage Divider (CVD) techniques for advanced touch sensing, averaging, filtering, oversampling, and threshold comparison.

Improved Peripheral Performance

The Direct Memory Access (DMA) Controller eliminates the need for CPU involvement in data transfers between all memory spaces and peripherals, thereby reducing the number of interrupts and improving peripheral performance.

Faster Interrupt Response Times

The Vectored Interrupt (VI) reduces response time by providing hardware ensured interrupt latency.

Enhanced System Features

The Controller Area Network (CAN) module works with CAN 2.0B and is fully backwards compatible with previous CAN modules. The products include the Memory Access Partition (MAP), which supports customers in data protection and bootloader applications. Device Information Area (DIA) is a dedicated memory space for factory-programmed device ID and peripheral calibration values. Additionally, the MCUs have improved serial communications, including UART with support for Asynchronous, DMX, DALI and LIN protocols along with higher-speed, standalone I2C and SPI serial communication interfaces.

Development Made Easy

The PIC18F K83 family will be supported by MPLAB® Code Configurator (MCC), a free software plug-in that provides a graphical interface to configure peripherals and functions specific to your application. MCC is incorporated into our award-winning development environments, the downloadable MPLAB X IDE and the cloud-based MPLAB Xpress IDE.

Building Blocks for Function Enablement

Analog to Digital Converter with Computation (ADC2)

The Analog to Digital Converter with Computation (ADC2) helps accelerate common math tasks normally done in software by offering modes like averaging, low-pass filter, oversampling and threshold comparison.
