´ 8 ELECTRICALLY ERASABLE EPROM
64K
GENERAL DESCRIPTION
The W27E520 is a high speed, low power Electrically Erasable and Programmable Read Only
´
Memory organized as 65,536 8 bits. It includes latches for the lower 8 address lines to multiplex
with the 8 data lines. To cooperate with the MCU, this device could save the external TTL
component, also cost and space. It requires only one supply in the range of 4.5V to 5.5V in normal
read mode. The W27E520 provides an electrical chip erase function. It will be a great convenient
when you need to change/update the contents in the device.

FUNCTIONAL DESCRIPTION
Read Mode
CE
OE
Unlike conventional UVEPROMs, which has
and
two control functions, the W27E520
PP
and one ALE (address_latch_enable) control functions. The ALE makes lower
OE
has one
/V
address A[7:0] to be latched in the chip when it goes from high to low, so that the same bus can be
used to output data during read mode. i.e. lower address A[7:0] and data bus DQ[7:0] are multiplexed.
PP
OE
/V controls the output buffer to gate data to the output pins. When addresses are stable, the
ACC
CE
address access time (T
) is equal to the delay from ALE to output (T ), and data are available at
OE
PP
/V , if T
ACC CE
and T timings are met.
OE
the outputs T after the falling edge of
Erase Mode
The erase operation is the only way to change data from "0" to "1." Unlike conventional UVEPROMs,
which use ultraviolet light to erase the contents of the entire chip (a procedure that requires up to half
an hour), the W27E520 uses electrical erasure. Generally, the chip can be erased within 100 mS by
using an EPROM writer with a special erase algorithm.
PP
PE
DD
DE
OE
There are two ways to enter Erase mode. One is to raise
/V to V (13V), V
= V (6.5V),
HH
A9 = V (13V), A10 = high A8&A11 = low, and all other address pins include AD[7:0] keep at fixed
low or high. Pulsing ALE high starts the erase operation. The other way is somewhat like flash, by
programming two consecutive commands into the device and then enter Erase mode. The two
commands are loading Data = AA(hex) to Addr. = 5555(hex) and Data = 10(hex) to Addr. =
2AAA(hex). Be careful to note that the ALE pulse widths of these two commands are different: One is
50uS, while the other is 100mS. Please refer to the Smart Erase Algorithm 1 & 2.
Erase Verify Mode
The device will enter the Erase Verify Mode automatically after Erase Mode. Only power down the
device can force the device enter Normal Read Mode again.
Program Mode
Programming is the only way to change cell data from "1" to "0." The program mode is entered when
PP
PP
DD
DP
OE
/V is raised to V (13V), V = V (6.5V), the address pins equal the desired addresses, and
the input pins equal the desired inputs. Pulsing ALE high starts the programming operation.
Program Verify Mode
The device will enter the Program Verify Mode automatically after Program Mode. Only power down
the device can force the device enter Normal Read Mode again.
Erase/Program Inhibit
Erase or program inhibit mode allows parallel erasing or programming of multiple chips with different
data. When ALE low, erasing or programming of non-target chips is inhibited, so that except for the
PP
/V pins, the W27E520 may have common inputs.
OE
ALE and
Standby Mode
DD
PP
/V
OE
The standby mode significantly reduces V current. This mode is entered when ALE and
keep high. In standby mode, all outputs are in a high impedance state.

System Considerations
An EPROM's power switching characteristics require careful device decoupling. System designers are
SB
DD
interested in three supply current issues: standby current levels (I ), active current levels (I ), and
transient current peaks produced by the falling and rising edges of ALE Transient current magnitudes
depend on the device output's capacitive and inductive loading. Proper decoupling capacitor selection
m
will suppress transient voltage peaks. Each device should have a 0.1 F ceramic capacitor connected
DD
between its V and GND. This high frequency, low inherent-inductance capacitor should be placed
m
as close as possible to the device. Additionally, for every eight devices, a 4.7 F electrolytic capacitor
DD
should be placed at the array's power supply connection between V and GND. The bulk capacitor
will overcome voltage slumps caused by PC board trace inductances.
