PIC16F887T-I/PT

This powerful yet easy-to-program (only 35 single word instructions) CMOS FLASH-based 8-bit microcontroller packs Microchip's powerful PIC® architecture into an 40- or 44-pin package.The PIC16F887 features 256 bytes of EEPROM data memory, self programming, an ICD, 2 Comparators, 14 channels of 10-bit Analog-to-Digital (A/D) converter, 1 capture/compare/PWM and 1 Enhanced capture/compare/PWM functions, a synchronous serial port that can be configured as either 3-wire Serial Peripheral Interface (SPI™) or the 2-wire Inter-Integrated Circuit (I²C™) bus and an Enhanced Universal Asynchronous Receiver Transmitter (EUSART). All of these features make it ideal for more advanced level A/D applications in automotive, industrial, appliances or consumer applications.

这款功能强大但易于编程(只有35个单字指令)的基于CMOS闪存的8位微控制器将Microchip强大的PIC架构封装到40或44引脚封装中。PIC16F887具有256字节EEPROM数据存储器、自编程、ICD、2个比较器、14通道10位模数(A/D)转换器、1个捕获/比较/PWM和1个增强型捕获/比较/PWM功能、一个可配置为三线式串行外设接口(SPI)或双线式内部集成电路(IC)总线的同步串行端口和一个增强型通用异步收发器(EUSART)。所有这些特性使其成为汽车、工业、家电或消费电子应用中更高级模数转换应用的理想之选。
