AT27C080
0360I–EPROM–4/03
Atmel’s scaled CMOS technology provides low active power consumption and fast program-
ming. Power consumption is typically 10 mA in active mode and less than 10 A in standby
mode.
The AT27C080 is available in a choice of packages, including; one-time programmable (OTP)
plastic PLCC, PDIP and TSOP. All devices feature two-line control (CE, OE) to give designers
the flexibility to prevent bus contention.
With high density 1M byte storage capability, the AT27C080 allows firmware to be stored reli-
ably and to be accessed by the system without the delays of mass storage media.
Atmel’s AT27C080 has additional features to ensure high quality and efficient production use.
The Rapid Programming Algorithm reduces the time required to program the part and guaran-
tees reliable programming. Programming time is typically only 50
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 algo-
rithms and voltages.
System
Considerations
Switching between active and standby conditions via the Chip Enable pin may produce tran-
sient voltage excursions. Unless accommodated by the system design, these transients may
exceed datasheet limits, resulting in device non-conformance. At a minimum, a 0.1
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 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
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.
