AT27C520

With 64K byte storage capability, the AT27C520 allows
firmware to be stored reliably and to be accessed by the
system without the delays of mass storage media.
Atmel's 27C520 has additional features to ensure high
quality and efficient production use. The Rapid
Program-
ming Algorithm reduces the time required to program the
part and guarantees reliable programming. Programming
time is typically only 50
μ
s/byte. The Integrated Product
Identification Code electronically identifies the device and
manufacturer. This feature is used by industry standard
programming equipment to select the proper programming
algorithms and voltages.
System Considerations
Switching under active conditions may produce transient
voltage excursions. Unless accommodated by the system
design, these transients may exceed data sheet limits,
resulting in device non-conformance. At a minimum, a 0.1
μ
F high frequency, low inherent inductance, ceramic
capacitor should be utilized for each device. This capacitor
should be connected between the V
CC
and Ground termi-
nals of the device, as close to the device as possible. Addi-
tionally, to stabilize the supply voltage level on printed cir-
cuit boards with large EPROM arrays, a 4.7
μ
F bulk elec-
trolytic capacitor should be utilized, again connected
between the V
CC
and Ground terminals. This capacitor
should be positioned as close as possible to the point
where the power supply is connected to the array.
