GENERAL DESCRIPTION
The MX29LV160BT/BB is a 16-mega bit Flash memory
organized as 2M bytes of 8 bits or 1M words of 16 bits.
MXIC's Flash memories offer the most cost-effective
and reliable read/write non-volatile random access
memory. The MX29LV160BT/BB is packaged in 44-pin
SOP, 48-pin TSOP and 48-ball CSP. It is designed to be
reprogrammed and erased in system or in standard
EPROM programmers.
The standard MX29LV160BT/BB offers access time as
fast as 70ns, allowing operation of high-speed micropro-
cessors without wait states. To eliminate bus conten-
tion, the MX29LV160BT/BB 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
MX29LV160BT/BB uses a command register to man-
age this functionality. The command register allows for
100% TTL level control inputs and fixed power supply
levels during erase and programming, while maintaining
maximum 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 MX29LV160BT/BB 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.
