System Considerations
Switching between active and standby conditions via the
Chip Enable pin may produce transient voltage excur-
sions. Unless accommodated by the system design, these
transients may exceed data sheet limits, resulting in de-
vice non-conformance. At a minimum, a 0.1
μ
F high fre-
quency, low inherent inductance, ceramic capacitor
should be utilized for each device. This capacitor should
be connected between the V
CC
and Ground terminals of
the device, as close to the device as possible. Additionally,
to stabilize the supply voltage level on printed circuit
boards with large EPROM arrays, a 4.7
μ
F bulk electrolytic
capacitor should be utilized, again connected between the
V
CC
and Ground terminals. This capacitor should be posi-
tioned as close as possible to the point where the power
supply is connected to the array.
The AT27C010/L in available in a choice of industry stand-
ard JEDEC-approved one-time programmable (OTP)
plastic PDIP, PLCC, and TSOP packages. All devices fea-
ture two line control (CE, OE) to give designers the flexibil-
ity to prevent bus contention.
With 128K byte storage capability, the AT27C010/L allows
firmware to be stored reliably and to be accessed by the
system without the delays of mass storage media.
Atmel’s 27C010/L have 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 100
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 program-
ming algorithms and voltages.
