In systems where CE » defines the write pulse width (within a longer WE » timing waveform), all setup, hold, and inactive WE » times should be measured relative to the CE » waveform. 2. Sampled, not 100% tested. 3. Refer to Command Definitions Table for valid AIN and DIN for block erase, byte write, or lock-bit configuration. 4. VPP should be held at VPPH1/2/3 (and if necessary RP » should be held at VHH) until determination of block erase, byte write, or lock-bit configuration success (SR.1/3/4/5 = 0). 5. See Ordering Information for device speeds (valid operational combinations). 6. See Transient Input/Output Reference Waveform and Transient Equivalent Testing Load Circuit (High Seed Configuration) for testing characteristics. 7. See Transient Input/Output Reference Waveform and Transient Equivalent Testing Load Circuit (Standard Configuration) for testing characteristics. |
