Manufacturer:HIT Description:Reset RP is used to reset all the memory circuitry and to set the chip in power down mode if this function is enabled by a proper setting of the Con- figuration Register. Erase and Program operations are controlled by an internal Program/Erase Con- troller (P/E.C.). Status Register data output on DQ7 provides a Data Polling signal, DQ6 and DQ2 provide Toggle signals and DQ5 provides error bit to indicate the state of the P/E.C operations. Memory Blocks The device features asymmetrically blocked archi- tecture. 74LV74FPEL has an array of 23 blocks and is divided into two banks A and B, providing Dual Bank operations. While programming or erasing in Bank A, read operations are possible into Bank B or vice versa. The memory also features an erase suspend allowing to read or program in another block within the same bank. Once suspended the erase can be resumed. The Bank Size and Sector- ization are summarized in Table 7. Parameter Blocks are located at the top of the memory ad- dress space for the 74LV74FPELE, and at the bot- tom for the 74LV74FPELF. The memory maps are shown in Tables 3, 4, 5 and 6. The Program and Erase operations are managed automatically by the P/E.C. Block protection against Program or Erase provides additional data security. All blocks are protected at Power Up. In- structions are provided to protect or unprotect any block in the application. A second register locks the protection status while WP is low (see Block Locking description). The Reset command does not affect the configuration of unprotected blocks and the Configuration Register status. |
