2 / 53 page  M58LW064A, M58LW064B 2/53 The devices support Asynchronous Random and Latch Enable Controlled Read with Page mode as well as Synchronous Burst Read with a config- urable burst. They also support pipelined synchro- nous Burst Read. Writing is Asynchronous or Asynchronous Latch Enable Controlled. The configurable synchronous burst read interface allows a high data transfer rate controlled by the Burst Clock K signal. It is capable of bursting fixed or unlimited lengths of data. The burst type, laten- cy and length are configurable and can be easily adapted to a large variety of system clock frequen- cies and microprocessors. A 16 Word or 8 Double- Word Write Buffer improves effective program- ming speed by up to 20 times when data is pro- grammed in full buffer increments. Effective Word programming takes typically 12 µs. The array ma- trix organisation allows each block to be erased and reprogrammed without affecting other blocks. Program and Erase operations can be suspended in order to perform either Read or Program in any other block and then resumed. All blocks are pro- tected against spurious programming and erase cycles at power-up. Any block can be separately protected at any time. The block protection bits can also be deleted, this is executed as one se- quence for all blocks simultaneously. Block protec- tion can be temporarily disabled. Each block can be programmed and erased over 100,000 cycles. Block erase is performed in typically 1 second. An internal Command Interface (C.I.) decodes In- structions to access/modify the memory content. The Program/Erase Controller (P/E.C.) automati- cally executes the algorithms taking care of the timings required by the program and erase opera- tions. Verification is internally performed and a Status Register tracks the status of the operations. The Ready/Busy output RB indicates the comple- tion of operations. Instructions are written to the memory through the Command Interface (C.I.) using standard micro- processor write timings. The device supports the Common Flash Interface (CFI) command set defi- nition. A Reset/Power-down mode is entered when the RP input is Low. In this mode the power consump- tion is lower than in the normal standby mode, the device is write protected and both the Status and the Burst Configuration Registers are cleared. A recovery time is required when the RP input goes High. The device is offered in various package versions, TSOP56 (14 x 20 mm), TSOP86 Type II (11.76 x 22.22 mm) and LBGA54 1mm ball pitch for the M58LW064A and PQFP80 for the M58LW064B. Table 1.
