The address must be set to “0 to 0FFFFH” and a (3) How to use the data security function “Data security” is the disabled function to read the data of the PROM. The following is the process in order to execute the data security. 1. Set ‘ON’ the jumper of attachment. 2. Program again. Then PROM programmer displays the error. The error means normally activity of the data security. It is not a trouble of the PROM programmer or the LSI. Notes • Data security is not executed when the data of all address have ‘FFH’ at the sequence 2 above. • The programming by a sequential operation “BLANK=>PROGRAM=>VERIFY” cannot be executed data security at the sequence 2 above. • Set to ‘OFF’ the jumper after executing the data security.

To probe reliability of the programmed devices, the screening procedure shown in the following figure should always be followed. • It is not possible to perform a writing test on the blank PROM. 100% yield, therefore, cannot be guaranteed. • Keeping the dry packing The environment must be held at a temperature of 30°C or less and a humidity level of 70% or less. • After opening the packing The preparation procedures shown in the following figure should always be followed prior to mounting the packages on the substrate. Note that the QIP package should be heat-soaked for 12 hours at 125°C immediately prior to mounting (This baking is called pre-baking). After pre-baking, a controlled environment must be maintained until soldering. The environment must be held at a temperature of 30°C or less and a humidity level of 70% or less. Please solder within 24 hours. a. Shipping with a blank PROM (Programming the data by yourself) QIP Writing data for program/Verifying Recommended process of screening b.
