â GENERAL DESCRIPTION
The MBM29F200TC/BC is a 2M-bit, 5.0 V-only Flash memory organized as 256K bytes of 8 bits each or 128K words of 16 bits each. The MBM29F200TC/BC is offered in a 48-pin TSOP and 44-pin SOP packages. This device is designed to be programmed in-system with the standard system 5.0 V VCC supply. 12.0 V VPP is not required for write or erase operations. The devices can also be reprogrammed in standard EPROM programmers. The standard MBM29F200TC/BC offers access times 55 ns and 90 ns allowing operation of high-speed microprocessors without wait states. To eliminate bus contention the device has separate chip enable (CE), write enable (WE), and output enable (OE) controls.
â FEATURES
⢠Single 5.0 V read, write, and erase
Minimizes system level power requirements
⢠Compatible with JEDEC-standard commands
Uses same software commands as E2PROMs
⢠Compatible with JEDEC-standard world-wide pinouts
48-pin TSOP (Package suffix: PFTN â Normal Bend Type, PFTR â Reversed Bend Type)
44-pin SOP (Package suffix: PF)
⢠Minimum 100,000 write/erase cycles
⢠High performance
55 ns maximum access time
⢠Sector erase architecture
One 16K byte, two 8K bytes, one 32K byte, and three 64K bytes.
Any combination of sectors can be concurrently erased. 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 writes 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
⢠Low Vcc write inhibit ⤠3.2 V
⢠Erase Suspend/Resume
Suspends the erase operation to allow a read in another sector within the same device
⢠Hardware RESET pin
Resets internal state machine to the read mode
⢠Sector protection
Hardware method disables any combination of sectors from write or erase operations
⢠Temporary sector unprotection
Hardware method temporarily enables any combination of sectors from write on erase operations.
