TPS77428 Datasheet t All typical values are at VCC = 5 V and TA = 250C. t The algebraic convention, where the less positive (more negative) limit is designated as minimum, is used in this data sheet for common-mode input voltage and threshold voltage levels only. NOTE 5: Refer to TIA/EIA-422-B for exact conditions. TPS77428 Price Notes: 1. CE may be delayed up to tACC - tCE after the address transition without impact on tACC. 2. OE may be delayed up to tCE - tOE after the falling edge of CE without impact on tCE or by tACC - tOE after an address change without impact on tACC. TPS77428 on stock Resetting the VTRIP Voltage To reset a VTRIP voltage, apply the programming volt- age (Vp) to the WP pin before a START condition is set up on SDA. Next, issue on the SDA pin the Slave Address AOh followed by the Byte Address 03h fol- lowed by OOh for the Data Byte in order to reset VTRIP. The STOP bit following a valid write operation initiates the programming sequence. Pin WP must then be brought LOW to complete the operation. Read Mode The M68AW064F is in the Read mode whenever Write Enable (W) is High with Output Enable (G) Low, and Chip Enable (E) is asserted. This pro- vides access to data from eight or sixteen, de- pending on the status of the signal UB and LB, of the l,048,576 locations in the static memory array, specified by the 16 address inputs. Valid data will be available at the eight or sixteen output pins |
