51 / 52 page ![]() January 22, 2007 22142F9 Am29BL162C 47 D A TA SH EET Revision F (June 20, 2000) Global The “preliminary” designation has been removed from the document. Parameters are now stable, and only speed, package, and temperature range combinations are expected to change in future data sheet revisions. Distinctive Characteristics Changed burst access time specification for the 65R speed option in the industrial temperature range from 19 to 18 ns. Product Selector Guide Replaced tOE with tBACC to more clearly distinguish burst mode access from asynchronous access times. Note however, that in burst mode, tOE and tBACC spec- ifications are identical. Changed tBACC for the 65R speed option in the industrial temperature range from 19 to 18 ns. Ordering Information Burn-in processing is no longer available. Requirements for Reading Array Data Array in Asynchronous (Non-Burst) Mode Clarified the description of how to terminate a burst mode read operation. Burst Mode Read with 40 MHz CLK figure Changed tBACC for the 65R speed option in the indus- trial temperature range from 19 to 18 ns. Read Operations table Changed tOE and tDF for the 65R speed option in the industrial temperature range from 19 to 18 ns. Burst Mode Read table Changed tOE and tBACC for the 65R speed option in the industrial temperature range from 19 to 18 ns. Burst Mode Read figure Corrected BAA# waveform to return high before the final clock cycle shown. Erase and Programming Performance table, Erase and Program Operations table, Alternate CE# Controlled Erase and Program Operations table Resolved differences in typical sector erase times. The typical sector erase time for all sectors is 3 sec. Revision F+1 (November 21, 2000) Added table of contents. Added Figure 1, In-System Sector Protect/Unprotect Algorithms figure to docu- ment (was missing from previous revisions). Revision F+2 (July 22, 2002) Pin Description, IND# End of Burst Indicator Clarified description of IND# function. Table 1, Device Bus Operations In burst read operations section, changed BAA# to “H” for “Load star ting Burst Address” and Terminate Current Burst Read Cycle; Start New Burst Read Cycle.” Requirements for Reading Array Data in Synchronous (Burst) Mode Modified section to clarify the description of the IND# and burst read functions. Burst Sequence Table Deleted table. Absolute Maximum Ratings Modified maximum DC voltage and maximum positive overshoot in Note 1 to refer to input and I/O pins. Revision F+3 (August 19, 2002) Product Selector Guide Added Note #2. Revision F+4 (September 12, 2002) Product Selector Guide Removed Note #2. Revision F+5 (November 22, 2002) Distinctive Characteristics Changed endurance to 1 million cycles. Erase Suspend/Erase Resume Command Sequence Noted that only asynchronous reads are allowed during the erase suspend mode. Erase/Program Operations table, Alternate CE# Controlled Erase/Program Operations table Changed typical sector erase time from 3 s to 1 s. Erase and Programming Performance Changed typical/maximum sector erase time from 3 s/60 s to 1 s/15 s, respectively. Changed typical chip erase time from 40 s to 15 s. Changed endurance to 1 million cycles. Added Asynchronous mode and Burst mode sections. Revision F+6 (June 10, 2004) Ordering Information Changed temperature range from -55°C to -40°C. Revision F+7 (October 29, 2004) Ordering Information Added: F= Industrial –40°C to +°85C) for Pb-free Package K= Extended –55°C to +125°C) for Pb-free Package |
