TQF | Thin Quad Flat Pack. Similar to QFP but with a lower profile and physically |
| smaller in length and width. |
TSOP | Thin Small Outline Package. A |
| (usually 0.025 inch pitch) on two sides. This package is very low profile and |
| commonly available in a reverse (mirror image) pin out used to simplify |
| circuit board layout; usually 32 to 44 pins. |
UV Erasable | The characteristic of an EPROM that allows it to be erased with exposure to |
| short |
| |
| source of such light is a mercury vapor tube much like an ordinary |
| fluorescent tube, but without the phosphor that turns the UV light emitted by |
| the mercury into visible light. The light from ordinary fluorescent lamps or |
| sunlight generally takes years to erase an EPROM. All UV erasable parts |
| have a quartz windowed ceramic package that allows exposure with UV light. |

Word width | The number of output pins that a memory device has. The most common size |
| for EPROMs is byte wide (8 bits) and “word” wide, or 16 bits. It can also |
| refer to the aggregate width of several memory devices used in a set. |
