erase operation completion.
• Sector protection
- Hardware method to disable any combination of
sectors from program or erase operations

GENERAL DESCRIPTION
The MX29LV002C T/B is a 2-mega bit Flash memory
organized as 256K bytes of 8 bits. MXIC's Flash memo-
ries offer the most cost-effective and reliable read/write
non-volatile random access memory. The MX29LV002C
T/B is packaged in 32-pin TSOP and 32-pin PLCC. It is
designed to be reprogrammed and erased in system or
in standard EPROM programmers.
The standard MX29LV002C T/B offers access time as
fast as 70ns, allowing operation of high-speed micropro-
cessors without wait states. To eliminate bus conten-
tion, the MX29LV002C T/B has separate chip enable
(CE#) and output enable (OE#) controls.
MXIC's Flash memories augment EPROM functionality
with in-circuit electrical erasure and programming. The
MX29LV002C T/B uses a command register to manage
this functionality. The command register allows for 100%
TTL level control inputs and fixed power supply levels
during erase and programming, while maintaining maxi-
mum EPROM compatibility.
MXIC Flash technology reliably stores memory contents
even after 100,000 erase and program cycles. The MXIC
cell is designed to optimize the erase and programming
mechanisms. In addition, the combination of advanced
tunnel oxide processing and low internal electric fields
for erase and program operations produces reliable cy-
cling. The MX29LV002C T/B uses a 2.7V~3.6V VCC
supply to perform the High Reliability Erase and auto
Program/Erase algorithms.
The highest degree of latch-up protection is achieved
with MXIC's proprietary non-epi process. Latch-up pro-
tection is proved for stresses up to 100 milliamps on
address and data pin from -1V to VCC + 1V.

Notes:
1. ADI = Address of Device identifier; A1=0, A0 = 0 for manufacturer code,A1=0, A0 = 1 for device code. A2-A17=do
not care.
(Refer to table 3)
DDI = Data of Device identifier : C2H for manufacture code, 59H/5AH (Top/Bottom) for device code.
X = X can be VIL or VIH
RA=Address of memory location to be read.
RD=Data to be read at location RA.
2. PA = Address of memory location to be programmed.
PD = Data to be programmed at location PA.
SA = Address of the sector to be erased.
3. The system should generate the following address patterns: 555H or 2AAH to Address A11~A0.
Address bit A12~A18=X=Don't care for all address commands except for Program Address (PA) and Sector
Address (SA). Write Sequence may be initiated with A12~A18 in either state.
4. For Sector Protect Verify operation:If read out data is 01H, it means the sector has been protected. If read out data
is 00H, it means the sector is still not being protected.
