AT27C010(L)
2
The AT27C010(L) in available in a choice of industry stan-
dard 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 μs/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 between active and standby conditions via the
Chip Enable pin may produce transient voltage excursions.
Unless accommodated by the system design, these tran-
sients 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 uti-
lized 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 positioned as close as
possible to the point where the power supply is connected
to the array.
