GENERAL DESCRIPTION
The MBM29DL400TC/BC are a 4M-bit, 3.0 V-only Flash memory organized as 512K bytes of 8 bits each or
256K words of 16 bits each. The MBM29DL400TC/BC are offered in a 48-pin TSOP(I) package. These devices
are designed to be programmed in-system with the standard system 3.0 V V
CC
supply. 12.0 V V
PP
and 5.0 V V
CC
are not required for write or erase operations. The devices can also be reprogrammed in standard EPROM
programmers.
MBM29DL400TC/BC provides simultaneous operation which can read a data while program/erase. The
simultaneous operation architecture provides simultaneous operation by dividing the memory space into two
banks. The device can allow a host system to program or erase in one bank, then immediately and simultaneously
read from the other bank.
The standard MBM29DL400TC/BC offer access times 55 ns and 120 ns, allowing operation of high-speed
microprocessors without wait states. To eliminate bus contention the devices have separate chip enable (CE),
write enable (WE), and output enable (OE) controls.
The MBM29DL400TC/BC are pin and command set compatible with JEDEC standard E
2
PROMs. 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 from 5.0 V and 12.0 V Flash or EPROM devices.
The MBM29DL400TC/BC are 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 about 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 devices automatically time the erase pulse widths and
verify proper cell margin.
A sector is typically erased and verified in 1.0 second. (If already completely preprogrammed.)
The devices also feature a sector erase architecture. The sector mode allows each sector to be erased and
reprogrammed without affecting other sectors. The MBM29DL400TC/BC are erased when shipped from the
factory.
The devices feature single 3.0 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 V
CC
detector automatically
inhibits write operations on the loss of power. The end of program or erase is detected by Data Polling of DQ
7
,
by the Toggle Bit feature on DQ
6
, or the RY/BY output pin. Once the end of a program or erase cycle has been
completed, the devices internally reset 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 MBM29DL400TC/BC memories 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 mechanism of hot electron injection.
