Also supports full chip erase • Boot Code Sector Architecture T = Top sector B = Bottom sector • Embedded EraseTM Algorithms Automatically pre-programs and erases the chip or any sector • Embedded programTM Algorithms Automatically programs and verifies data at specified address • Data Polling and Toggle Bit feature for detection of program or erase cycle completion • Ready/Busy output (RY/BY) Hardware method for detection of program or erase cycle completion • Automatic sleep mode When addresses remain stable, automatically switches themselves to low power mode • Low VCC write inhibit ≤ 2.5 V • Erase Suspend/Resume Suspends the erase operation to allow a read data and/or program in another sector within the same device • Sector protection Hardware method disables any combination of sectors from program or erase operations • Sector Protection set function by Extended sector protect command • Temporary sector unprotection Temporary sector unprotection via the RESET pin • In accordance with CFI (Common Flash Memory Interface) Embedded EraseTM and Embedded ProgramTM are trademarks of Advanced Micro Devices, Inc. 1 page MBM29LV016T-80/-90/-12/MBM29LV016B-80/-90/-12 Sector SA0 SA1 SA2 SA3 SA4 SA5 SA6 SA7 SA8 SA9 SA10 SA11 SA12 SA13 SA14 SA15 SA16 SA17 SA18 SA19 SA20 SA21 SA22 SA23 SA24 SA25 SA26 SA27 SA28 SA29 SA30 SA31 SA32 SA33 SA34 Sector Size 16 Kbytes 8 Kbytes 8 Kbytes 32 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes 64 Kbytes (× 8) Address Range 00000H to 03FFFH 04000H to 05FFFH 06000H to 07FFFH 08000H to 0FFFFH 10000H to 1FFFFH 20000H to 2FFFFH 30000H to 3FFFFH 40000H to 4FFFFH 50000H to 5FFFFH 60000H to 6FFFFH 70000H to 7FFFFH 80000H to 8FFFFH 90000H to 9FFFFH A0000H to AFFFFH B0000H to BFFFFH C0000H to CFFFFH D0000H to DFFFFH E0000H to EFFFFH F0000H to FFFFFH 100000H to 10FFFFH 110000H to 11FFFFH 120000H to 12FFFFH 130000H to 13FFFFH 140000H to 14FFFFH 150000H to 15FFFFH 160000H to 16FFFFH 170000H to 17FFFFH 180000H to 18FFFFH 190000H to 19FFFFH 1A0000H to 1AFFFFH 1B0000H to 1BFFFFH 1C0000H to 1CFFFFH 1D0000H to 1DFFFFH 1E0000H to 1EFFFFH 1F0000H to 1FFFFFH MBM29LV016B Bottom Boot Sector Architecture 5 5 Page MBM29LV016T-80/-90/-12/MBM29LV016B-80/-90/-12 The manufacturer and device codes may also be read via the command register, for instances when the MBM29LV016T/B are erased or programmed in a system without access to high voltage on the A9 pin. The command sequence is illustrated in Table 6. (Refer to Autoselect Command section.) Byte 0 (A0 = VIL) represents the manufacture’s code (Fujitsu = 04H) and A0 = VIH represents the device identifier code (MBM29LV016T = C7H, MBM29LV016B = 4CH). All identifiers for manufactures and device will exhibit odd parity with DQ7 defined as the parity bit. In order to read the proper device codes when executing the autoselect, A1 must be VIL. (See Tables 3.1 and 3.2.) The device code is C7H (for top boot block) or 4CH (for bottom boot block). In order to determine which sectors are write protected, A1 must be at VIH while running through the sector addresses; if the selected sector is protected, a logical ‘1’ will be output on DQ0 (DQ0 = 1).
