Microchip PIC18F47J53全速USB开发方案

Microchip 公司的PIC18F47J53是8位和USB微控制器(MCU),提供128KB闪存程序存储器和4KB RAM,具有全速USB V2.0功能,支持控制,中断,同步和块传输,支持多达32个端点,采用nanoWatt XLP技术可大大降低功耗,主要用在手持消费类电子设备,医疗设备以及其它需要低功耗和USB连接的应用.本文介绍了PIC18F47J53主要特性,方框图, PIC18F4XJ5X全速USB演示板所用主要元器件和电路图.

This family introduces a new line of low-voltage Universal Serial Bus (USB) microcontrollers with the main traditional advantage of all PIC18 microcontrollers, namely, high computational performance and a rich feature set at an extremely competitive price point.

These features make the PIC18F47J53 family a logical choice for many high-performance applications, where cost is a primary consideration.

PIC18F47J53主要特性:

Universal Serial Bus Features:

• USB V2.0 Compliant

• Low Speed (1.5 Mbps) and Full Speed (12 Mbps)

• Supports Control, Interrupt, Isochronous and Bulk Transfers

• Supports up to 32 Endpoints (16 bidirectional)

• USB module can use any RAM Location on the Device as USB Endpoint Buffers

• On-Chip USB Transceiver with Crystal-Less Operation
