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 cur- rent is typically less than 10 µA. The AT27C516 is available in industry-s tandard JEDEC-approved one-time program- mable (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 AT27C516 have additional features to ensure high quality and efficient pro- duction 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. 512K (32K x 16) OTP EPROM AT27C516 0362E–EPROM–1/08

0362E–EPROM–1/08 AT27C516 3. System Considerations Switching between active and standby conditions via the Chip Enable pin may produce tran- sient voltage excursions. Unless accommodated by the system design, these transients may exceed datasheet 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 stabi lize 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 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. 4. Block Diagram Note: 1. Minimum voltage is -0.6V DC which may undershoot to -2.0V fo r pulses of less than 20 ns. Maximum output pin voltage is VCC + 0.75V DC which may overshoot to +7.0 volts for pulses of less than 20 ns. 5. Absolute Maximum Ratings* Maximum Ratings” may cause permanent dam- age to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability Voltage on Any Pin with (1) Voltage on A9 with VPP Supply Voltage with

0362E–EPROM–1/08 AT27C516 Notes: 1. X can be V IL or VIH. 2. Refer to Programming Characteristics. 3. V H = 12.0 ± 0.5V. 4. Two identifier bytes may be selected. All Ai inputs are held low (V IL), except A9 which is set to VH and A0 which is toggled low (VIL) to select the Manufacturer’s Identification byte and high (VIH) to select the Device Code byte. 5. Standby V CC current (ISB) is specified with VPP = VCC. VCC > VPP will cause a slight increase in ISB. Notes: 1. V CC must be applied simultaneously with or before VPP, and removed simultaneously with or after VPP. 2. V PP may be connected directly to VCC, except during programming. The supply current would then be the sum of ICC and IPP. 6.

0362E–EPROM–1/08 AT27C516 18. Rapid Programming Algorithm A 50 µs PGM pulse width is used to program. The addr ess 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 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. V PP is then lowered to 5.0V and V CC to 5.0V. All words are read again and compared with the original data to determine if the device passes or fails.
