TI 便携式媒体播放器解决方案
扩展系列双电源电平转换设备
This CompactFlash (CF) interface chip is designed to provide a singlechip solution for CF card interfaces. Separate VCC rails for the system bus side and the CF connector bus side allow voltage-level shifting.This is helpful for interfacing between a core chipset, which may operate
from 3.3 V down to 1.65 V, and CF cards with 3.3-V or 5-V supply voltages.
Key Features
- Level translation supports both 3.3- and 5-V CompactFlash cards
- High degree of integration
- Schmidt-trigger inputs for CompactFlash control signals
- Ioff and /MASTER_EN (shutdown) pin
- Internal decode logic for direction control (DIR)
- Robust ESD protection (+8-kV HBM) on card pins Applications
- PDAs
- Handheld scanners
- Set-top boxes
- Network equipment
