95 / 102 page  November 2007 Datasheet Order Number: 290701-18 95 Numonyx™ Wireless Flash Memory (W18) Table 45: Burst Read Information for Non-muxed Device Table 44: Protection Register Information Offset P = 39h Length Description (Optional Flash Features and Commands) Add. Hex Code Value (P + E)h 1 Number of Protectuib Register fields in JEDEC ID space. “00h” indicates that 256 protection fields are available. 47: --01 1 (P + E)h (P + 10)h (P + 11)h (P + 12)h 4 Protection Field 1: Protection Description This field describes user-available One Time Programmable (OTP) Protection Register bytes, Some are pre-programmed with device- unique serial numbers. Others are user-programmable. Bits are 0-15 point to the Protection Register lock byte, the section’s first byte. The following bytes are factory pre-programmed and user-programmable: • bits 0-7 = Lock/bytes JEDEC-plane physical low address • bites 8-15 = Lock/bytes JEDEC-plane physical high address • bits 16-23 = “n” such that 2n = factory pre- programmed bytes • bits 24-31 = “n” such that 2n = user-programmable bytes 48: 49: 4A: 4B: --80 --00 --03 --03 80h 00h 8 byte 8 byte Offset (1) Length Description Hex P = 39h (Optional flash features and commands) Add. Code Value (P+13)h 1 4C: --03 8 byte (P+14)h 1 4D: --04 4 (P+15)h 1 4E: --01 4 (P+16)h 1 Synchronous mode read capability configuration 2 4F: --02 8 (P+17)h 1 Synchronous mode read capability configuration 3 50: --03 16 (P+18)h 1 Synchronous mode read capability configuration 4 51: --07 Cont Page Mode Read capability bits 0–7 = “n” such that 2n HEX value represents the number of read-page bytes. See offset 28h for device word width to determine page-mode data output width. 00h indicates no read page buffer. Number of synchronous mode read configuration fields that follow. 00h indicates no burst capability. Synchronous mode read capability configuration 1 Bits 3–7 = Reserved bits 0–2 “n” such that 2n+1 HEX value represents the maximum number of continuous synchronous reads when the device is configured for its maximum word width. A value of 07h indicates that the device is capable of continuous linear bursts that will output data until the internal burst counter reaches the end of the device’s burstable address space. This field’s 3-bit value can be written directly to the Read Configuration Register bits 0–2 if the device is configured for its maximum word width. See offset 28h for word width to determine the burst data output width. |
