PAL16P1AJM Datasheet
PAL16P1AJM Price Organisation of Protection Word The Protection word protects EEPROM words from being written. The bits in protection word are one time programmable (OTP) which means that once they have been set t0 1 they can not be reset to O any more. Every EEPROM word is protected by a bit pair in Protection word. State 00 0f the pair means that the word is not protected, state 11 means write protection. 01 and 10 states are not allowed. Due to the OTP feature of bits in Protection word a word once protected becomes read only and can not be reverted back to RW. Please note that it is possible to protect the Protection word itself, in that case the protection system is locked and cannot be changed any more. PAL16P1AJM on stock
BiMOS II devices have higher data-input rates than the original BiMOS circuits. With a 5 V supply, they will operate to at least 3.3 MHz. At 12 V, higher speeds are possible. The CMOS inputs are compatible with standard CMOS and NMOS logic levels. TTL circuits may require the use of appropri- ate pull-up resistors to ensure a proper input-logic high. A CMOS serial data output, allows cascading these devices in multiple drive-line applications required by many dot matrix, alphanumeric, and bar graph displays. |
