PACKAGE

鈥?40-pin TSOP

GENERAL DESCRIPTION

The MX29LV033 is a 32-mega bit Flash memory orga-

nized as 4M bytes of 8 bits. MXIC's Flash memories

offer the most cost-effective and reliable read/write non-

volatile random access memory. The MX29LV033 is

packaged in 40-pin TSOP. It is designed to be repro-

grammed and erased in system or in standard EPROM

programmers.

The standard MX29LV033 offers access time as fast as

70ns, allowing operation of high-speed microprocessors

without wait states. To eliminate bus contention, the

MX29LV033 has separate chip enable (CE) and output

enable (OE) controls.

P/N:PM0679

MXIC's Flash memories augment EPROM functionality

with in-circuit electrical erasure and programming. The

MX29LV033 uses a command register to manage this

functionality.

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 program mechanisms. In addition, the

combination of advanced tunnel oxide processing

and low internal electric fields for erase and

programming operations produces reliable cycling.
