5 / 40 page ![]() 2007-2022 Microchip Technology Inc. and its subsidiaries DS20002029G-page 5 34AA02/34LC02 13 TAA Output Valid from cloCk — 3500 ns 1.7V VCC < 1.8V (Note 2) — 900 ns 1.8V VCC 5.5V (Note 2) — 400 ns 2.5V VCC 5.5V (34LC02) (Note 2) 14 TBUF Bus Free Time: The time the bus must be free before a new transmission can start 4700 — ns 1.7V VCC < 1.8V 1300 — ns 1.8V VCC 5.5V 500 — ns 2.5V VCC 5.5V (34LC02) 15 TSP Input Filter Spike Suppression (SDA and SCL pins) —50 ns 34AA02 (Note 1 and Note 3) 16 TWC Write Cycle Time (byte or page) —5 ms 17 Endurance 1,000,000 — cycles +25°C, 5.5V, Page Mode (Note 4) TABLE 1-2: AC SPECIFICATIONS AC CHARACTERISTICS Electrical Characteristics: Industrial (I): TA = -40°C to +85°C Extended (E): TA = -40°C to +125°C Param. No. Symbol Characteristic Min. Max. Units Conditions Note 1: Not 100% tested. CB = total capacitance of one bus line in pF. 2: As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region (minimum 300 ns) of the falling edge of SCL to avoid unintended generation of Start or Stop conditions. 3: The combined TSP and VHYS specifications are due to new Schmitt Trigger inputs, which provide improved noise spike suppression. This eliminates the need for a TI specification for standard operation. 4: This parameter is not tested but ensured by characterization. |
