AT27C010/L

Description

The AT27C010/L is a low-power, high performance 1,048,576 bit one-time program­mable read only memory (OTP EPROM) organized as 128K by 8 bits. They require
only one 5V power supply in normal read mode operation. Any byte can be accessed
in less than 45 ns, eliminating the need for speed reducing WAIT states on high per­formance microprocessor systems.

Two power versions are offered. In read mode, the AT27C010 typically consumes 25
mA while the AT27C010L requires only 8 mA. Standby mode supply current for both
parts is typically less than 10

µA.

System Considerations

The AT27C010/L in available in a choice of industry stand­ard JEDEC-approved one-time programmable (OTP)
plastic PDIP, PLCC, and TSOP packages. All devices fea­ture 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



Program­ming 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 pr oper program­ming algorithms and voltages.

Description (Continued)

Switching between active and standby conditions via the
Chip Enable pin ma y 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 µF 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 th e 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

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.

Rapid Programming Algor ithm

A 100 µs PGM pulse width is used to program. The ad­dress is set to the first location. V

CC

is raised to 6.5V and

V

PP

is raised to 13.0V. Each address is first programmed

with one 100 µs

PGM pulse without verification. Then a
verification / reprogramming loop is executed for each ad­dress. In the event a byte fails to pass verification, up to
10 successive 100 µs pulses are applied with a verifica­tion after each pulse. If the byte fails to verify after 10
pulses have been applied, the part is considered failed.
After the byte ve rifies properly, the next address is se­lected until all have been checked. V

PP

is then lowered to

5.0V and V

CC

to 5.0V. All bytes are read again and com­pared with the original data to determine if the dev ice
passes or fails.
