AT27BV020-90CI 数据手册

Atmel’s innovative design techniques provide fast speeds

that rival 5V parts while keeping the low power consump-

tion of a 3V supply. At V_CC= 2.7V, any byte can be

accessed in less than 90 ns. With a typical power dissipa-

tion of only 18 mW at 5 MHz and V_CC= 3V, the AT27BV020

consumes less than one fifth the power of a standard 5V

EPROM. Standby mode supply current is typically less than

1 µA at 3V. The AT27BV020 simplifies system design and

stretches battery lifetime even further by eliminating the

need for power supply regulation

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. The AT27BV020 programs

exactly the same way as a standard 5V AT27C020 and

uses the same programming equipment.

The AT27BV020 is available in industry standard JEDEC

approved one-time programmable (OTP) plastic PLCC,

TSOP and VSOP packages, as well as a 42-ball, 1 mm

pitch, plastic chip-scale Ball Grid Array package (CBGA).

All devices feature two-line control (CE, OE) to give design-

ers the flexibility to prevent bus contention.

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 µF high frequency,

low inherent inductance, ceramic capacitor should be uti-

lized for each device. This capacitor should be connected

between the V_CCand 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 µF bulk electrolytic capacitor should

be utilized, again connected between the V_CCand Ground

terminals. This capacitor should be positioned as close as

possible to the point where the power supply is connected

to the array.

The AT27BV020 operating with V_CCat 3.0V produces TTL

level outputs that are compatible with standard TTL logic

devices operating at V_CC= 5.0V. At V_CC= 2.7V, the part is

compatible with JEDEC approved low voltage battery oper-

ation (LVBO) interface specifications. The device is also

capable of standard 5-volt operation making it ideally suited

for dual supply range systems or card products that are

pluggable in both 3-volt and 5-volt hosts.

Atmel's AT27BV020 has additional features to ensure high

quality and efficient production use. The Rapid^™Program-
