W27E520  
´ 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.

W27E520  
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.
