10 / 44 page June 12, 2002 Am29PL160C 9 Page Mode Read The Am29PL160C is capable of fast Page mode read and is compatible with the Page mode Mask ROM read operation. This mode provides faster read access speed for random locations within a page. The Page size of the Am29PL160C device is 8 words, or 16 bytes, with the appropriate Page being selected by the higher address bits A3–A19 and the LSB bits A0–A2 (in the word mode) and A-1 to A2 (in the byte mode) determining the specific word/byte within that page. This is an asynchronous operation with the micropro- cessor supplying the specific word or byte location. The random or initial page access is equal to tACC or tCE and subsequent Page read accesses (as long as the locations specified by the microprocessor falls within that Page) is equivalent to tPACC. When CE# is deasserted and reasserted for a subsequent access, the access time is tACC or tCE. Here again, CE# selects the device and OE# is the output control and should be used to gate data to the output pins if the device is se- lected. Fast Page mode accesses are obtained by keeping A3–A19 constant and changing A0 to A2 to select the specific word, or changing A-1 to A2 to se- lect the specific byte, within that page. The following tables determine the specific word and byte within the selected page: Table 2. Word Mode Table 3.
