Sharp LH28F008SC
The LH28F008SC SmartVoltage FlashFile memory maintains backwards-compatiblity with SHARP’S 28F008SA. These similarities enable a clean upgrade from the 28F008SA to LH28F008SC. When upgrading, it is important to note the following differences: • Because of new feature support, the two devices have different device codes.FEATURES
