Description
The AT27C516 is a low-power, high performance 524,288-bit one-time programmable
read only memory (OTP EPROM) organized 32K by 16 bits. It requires only one 5V
power supply in normal read mode operation. Any word can be accessed in less than
45 ns, eliminating the need for speed reducing WAIT states. The by-16 organization
make this part ideal for high-performance 16- and 32-bit microprocessor systems.
In read mode, the AT27C516 typically consumes 15 mA. Standby mode supply current is typically less than 10 µA.

The AT27C516 is available in industry standard JEDECapproved one-time programmable (OTP) plastic PLCC and
VSOP packages. The device features two-line control (CE,
OE) to eliminate bus contention in high-speed systems.
With 32K word storage capability, the AT27C516 allows
firmware to be stored reliably and to be accessed by the
system without the delays of mass storage media.
Atmel’s 27C516 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 50 µs/word. 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 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 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 VCC 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 Algorithm
A 50 µs PGM pulse width is used to program. The address
is set to the first location. VCC is raised to 6.5V and VPP is
raised to 13.0V. Each address is first programmed with one
50 µs PGM pulse without verification. Then a verification /
reprogramming loop is executed for each address. In the
event a word fails to pass verification, up to 10 successive
50 µs pulses are applied with a verification after each
pulse. If the word fails to verify after 10 pulses have been
applied, the part is considered failed. After the word verifies
properly, the next address is selected until all have been
checked. VPP is then lowered to 5.0V and VCC to 5.0V. All
words are read again and compared with the original data
to determine if the device passes or fails.
