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 onl y one 5V
power supply in no rmal r ead mod e o per at ion . A ny word ca n b e ac c es sed i n l es s tha n
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.
Note: PLCC Package Pins 1 and 23 are

The AT27C516 is available in industry standard JEDECapproved one-time progr am ma ble (OTP ) pl astic P LCC an d
VSOP packages. The dev ice f eatures tw o-li ne contro l (CE

With 32K word storage ca pability, the AT2 7C516 allows
firmware to be stored reliably and to be accessed by the
system without the delays of mass storage media.
Atmel’s 27C516 have ad ditional f eatures to ensure high
quality and efficient producti on use. The Rapi d™ Progra mming Algori thm reduc es the time require d to prog ram the
part and guarantees reliable programming. Programming
time is typically only 50 µs/word. The Integrated Product
Identification Code electronica lly identifi es the devic e and
manufacturer. This feature is used by industry standard
programming equi pmen t to se lect the prop er progr ammi ng
algorithms and voltages.

System Considerations
Switching between active and standby conditions via the

Chip Enable pin may produ ce tra ns ien t vo ltag e ex cu rs i ons .
Unless accommodated by the system design, these transients may exceed data sheet limits, resulting in device
non-conforman ce. At a mini mum, 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
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
terminals. This capacitor should be positioned as close as
possible to the point where the power supply is connected
to the array.
