Description

The AT27C512R is a low-power, high-performance 524,288-bit one-time programma-

ble read only memory (OTP EPROM) organized 64K by 8 bits. It requires 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.

Atmel’s scaled CMOS technology provides high-speed, lower active power consump-

tion, and significantly faster programming. Power consumption is typically only 8 mA

in Active Mode and less than 10 µA in Standby.

Note:

PLCC Package Pins 1 and

17 are DON’T CONNECT.

The AT27C512R is available in a choice of industry stan-

dard JEDEC-approved one-time programmable (OTP)

plastic PDIP, PLCC, SOIC, and TSOP packages. All

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

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.

With 64K byte storage capability, the AT27C512R allows

firmware to be stored reliably and to be accessed by the

system without the delays of mass storage media.

Atmel’s 27C512R has 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.

RapidProgramming Algorithm

A 100 µs CE pulse width is used to program. The address

is set to the first location. V_CCis raised to 6.5V and OE/V_PP

is raised to 13.0V. Each address is first programmed with

one 100 µs CE pulse without verification. Then a verifica-

tion/reprogramming loop is executed for each address. In

the event a byte fails to pass verification, up to 10 succes-

sive 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 verifies

properly, the next address is selected until all have been

checked. OE/V_PPis then lowered to V_ILand V_CCto 5.0V. All

bytes are read again and compared with the original data to

determine if the device passes or fails.
