Sampled only, not 100% tested. 2. G may be delayed by up to tELQV - tGLQV after the falling edge of E without increasing tELQV. 3. The temperature range –40 to 125 °C is guaranteed at 70ns with High Speed Interface test condition and VCC = 5V ± 5%. Table 12A. Read AC Characteristics (TA = 0 to 70 °C, –20 to 85°C, –40 to 85°C or –40 to 125°C)(3) Block Erase (BE) instruction. This instruction uses a minimum of six write cycles. The Erase Set-up command 80h is written to address 5555h on third cycle after the two coded cycles. The Block Erase Confirm command 30h is written on sixth cycle after another two coded cycles. During the input of the second command an address within the block to be erased is given and latched into the memory. Additional Block Erase confirm com- mands and block addresses can be written sub- sequently to erase other blocks in parallel, without further coded cycles. The erase will start after an Erase timeout period of about 100 µs. Thus, addi- tional Block Erase commands must be given within this delay. The input of a new Block Erase com- mand will restart the timeout period. The status of the internal timer can be monitored through the level of DQ3, if DQ3 is ’0’ the Block Erase Com- mand has been given and the timeout is running, if DQ3 is ’1’, the timeout has expired and the P/E.C is erasing the block(s). Before and during Erase timeout, any command different from 30h will abort the instruction and reset the device to read array mode. It is not necessary to program the block with 00h as the P/E.C. will do this automatically before erasing to FFh. Read operations after the sixth rising edge of W or E output the status register bits. During the execution of the erase by the P/E.C., the memory accepts only the ES (Erase Suspend) and RST (Reset) instructions. Data Polling bit DQ7 returns ’0’ while the erasure is in progress and ’1’ when it has completed. The Toggle Bit DQ6 toggles during the erase operation. It stops when erase is completed. After completion the Status Register bit DQ5 returns ’1’ if there has been an Erase Failure because erasure has not completed even after the maximum number of erase cycles have been executed. In this case, it will be necessary to input a Reset (RST) to the command interface in order to reset the P/E.C. 11/31 M29F040 |
