GENERAL DESCRIPTION
The KH29LV320C T/B is a 32-mega bit Flash memory
organized as 4M bytes of 8 bits and 2M words of 16 bits.
MXIC's Flash memories offer the most cost-effective and
reliable read/write non-volatile random access memory.
The KH29LV320C T/B is packaged in 48-pin TSOP. It is
designed to be reprogrammed and erased in system or in
standard EPROM programmers.
The standard KH29LV320C 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 KH29LV320CT/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
KH29LV320C T/B 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

Legend:
X=Don't care
RA=Address of the memory location to be read.
RD=Data read from location RA during read operation.
PA=Address of the memory location to be programmed.
Addresses are latched on the falling edge of the WE# or CE#
pulse.
PD=Data to be programmed at location PA. Data is latched on
the rising edge of WE# or CE# pulse.
SA=Address of the sector to be erased or verified. Address
bits A20-A12 uniquely select any sector.
ID=22A7h(Top), 22A8h(Bottom)
Notes:
1. See Table 1 for descriptions of bus operations.
2. All values are in hexadecimal.
3. Except when reading array or Automatic Select data, all bus cycles are write operation.
4. The Reset command is required to return to the read mode when the device is in the Automatic Select mode or if Q5 goes
high.
5. The fourth cycle of the Automatic Select command sequence is a read cycle.
6. The data is 99h for factory locked and 19h for not factory locked.
7. The data is 00h for an unprotected sector/sector block and 01h for a protected sector/sector block. In the third cycle of the
command sequence, address bit A20=0 to verify sectors 0~31, A20=1 to verify sectors 32~70 for Top Boot device.
8. Command is valid when device is ready to read array data or when device is in Automatic Select mode.
9. The system may read and program functions in non-erasing sectors, or enter the Automatic Select mode, when in the erase
Suspend mode. The Erase Suspend command is valid only during a sector erase operation.
10. The Erase Resume command is valid only during the Erase Suspend mode.
