W81E381D General Description
The W81E381 is 8052-based USB device with 20 Kbytes flash memory. By integrating the USB1.1 transceiver, SIE, enhanced 8032 code, 20K Flash memory, extra 256 Byte RAM, power regulator, and general purpose I/O in single chip, W81E381D/W81E381AD creates a very low cost-effective solution that provides superior time-to-market advantages. The GPIO provides an easy interface to popular interface, such as ATAPI, EPP, RS232, MCU and DSP interface.
W81E381D Features
• Fully compliant with the Universal Serial Bus Specification version 1.1.
• Support USB Suspend and Resume operation for power-down standby.
• Support USB remote wake up function.
• Embedded microprocessor--8052 with extra 256Bytes RAM for data processing/storage, 20 Kbytes of In-System Programmable Flash memory.
• Internal generated 12MHz clock for 8052 use (the same as standard 8052 uses 24 MHz clock outside)
• External and separated 8052 clock input supported
• 6 clock per instruction 8052 core
• Flash support 512Byte erase block
• Software setting, 2KByte block programmable write protection for Flash memory
• 6-Mhz crystal/oscillator input for both Full speed application with limited EMI affection
• Support smart card interface, including serial interface memory card, and SCIO & SCCLK pins could be programmed as GPIO pins by registers setting
• Built-in 3.3V power regulator for single 5V power operation
• Internal PLL for USB and SC requirements
• Support one Control endpoint for command (8 bytes), and four endpoints 1, 2, 3, 4 (Bulk In, Bulk Out Interrupt In, and Interrupt Out) for data.
BulkIn, BulkOut with 16 bytes FIFO
InterruptIn, InterruptOut with 8 bytes FIFO
