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 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.

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
) to eliminate bus contention in high-speed systems.
OE 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.

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.

A 50 µs PGM pulse width is used to program. The add ress is set to the first location. V raised to 13.0V. Each address is first programmed with one 50 µs PGM 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 without verification. Then a verification /
