MBM29F200TC-55/-70/-90/MBM29F200BC-55/-70/-90 s PACKAGE 48-pin TSOP (I) 44-pin SOP Marking Side www.datasheet4u.com Marking Side Marking Side (FPT-48P-M19) (FPT-48P-M20) (FPT-44P-M16) 2 MBM29F200TC-55/-70/-90/MBM29F200BC-55/-70/-90 s 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 www.datasheet4u.com 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. The MBM29F200TC/BC is pin and command set compatible with JEDEC standard. Commands are written to the command register using standard microprocessor write timings. Register contents serve as input to an internal state-machine which controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the devices is similar to reading from12.0 V Flash or EPROM devices. The MBM29F200TC/BC is programmed by executing the program command sequence. This will invoke the Embedded Program Algorithm which is an internal algorithm that automatically times the program pulse widths and verifies proper cell margin. Typically, each sector can be programmed and verified in less than 0.5 seconds. Erase is accomplished by executing the erase command sequence. This will invoke the Embedded Erase Algorithm which is an internal algorithm that automatically preprograms the array if it is not already programmed before executing the erase operation. During erase, the device automatically times the erase pulse widths and verifies proper cell margin. A sector is typically erased and verified in 1.0 second (if already completely preprogrammed.). The devices also features a sector erase architecture. The sector mode allows each sector to be erased and reprogrammed without affecting other sectors. The MBM29F200TC/BC is erased when shipped from the factory. The devices features single 5.0 V power supply operation for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. A low VCC detector automatically inhibits write operations on the loss of power. The end of program or erase is detected by Data Polling of DQ7, by the Toggle Bit feature on DQ6, or the RY/BY output pin. Once the end of a program or erase cycle has been completed, the device internally resets to the read mode. Fujitsu’s Flash technology combines years of EPROM and E2PROM experience to produce the highest levels of quality, reliability, and cost effectiveness. The MBM29F200TC/BC memory electrically erase the entire chip or all bits within a sector simultaneously via Fowler-Nordhiem tunneling. The bytes/words are programmed one byte/word at a time using the EPROM programming mechanis.
