At V CC = 2.7V, any word can be accessed in less than 120 ns. With a typical power dissipation of only 18 mW at 5 MHz and VCC = 3V, the AT27BV1024 consumes less than one fifth the power of a standard 5V EPROM. Standby mode supply current is typically less than 1 µA at 3V. The AT27BV1024 simplifies system design and stretches battery lifetime even further by eliminating the need for power supply regulation. The AT27BV1024 is available in industry standard JEDECapproved one-time programmable (OTP) plastic PLCC and VSOP packages. All devices feature two-line control (CE, OE) to give designers the flexibility to prevent bus contention. The AT27BV1024 operating with V CC at 3.0V produces TTL level outputs that are compatible with standard TTL logic devices operating at VCC = 5.0V. At VCC = 2.7V, the part is compatible with JEDEC approved low voltage battery operation (LVBO) interface specifications. The device is also capable of standard 5-volt operation making it ideally suited for dual supply range systems or card products that are pluggable in both 3-volt and 5-volt hosts. Atmel’s AT27BV1024 has additional features to ensure high quality and efficient production use. The Rapid™ Pro- Block Diagram 2 AT27BV1024 gramming Algorithm reduces the time required to program the part and guarantees reliable programming. Programming time is typically only 100 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. The AT27BV1024 programs exactly the same way as a standard 5V AT27C1024 and uses the same programming equipment. 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. AT27BV1024 Absolute Maximum Ratings* Temperature Under Bias ................................ -55°C to +125°C *NOTICE: Storage Temperature ..................................... -65°C to +150°C Voltage on Any Pin with Respect to Ground .........................................-2.0V to +7.0V(1) Voltage on A9 with Respect to Ground ......................................-2.0V to +14.0V(1) Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

The AT27BV1024 has the same Product Identification Code as the AT27C1024. Both are programming compatible. 8 AT27BV1024 AT27BV1024 Rapid Programming Algorithm A 100 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 100 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 100 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. 9 Ordering Information ICC (mA) tACC (ns) Active Standby Ordering Code Package 90 8 0.02 AT27BV1024-90JC AT27BV1024-90VC 44J 40V Commercial (0°C to 70°C) 8 0.02 AT27BV1024-90JI AT27BV1024-90VI 44J 40V Industrial (-40°C to 85°C) 8 0.02 AT27BV1024-12JC AT27BV1024-12VC 44J 40V Commercial (0°C to 70°C) 8 0.02 AT27BV1024-12JI AT27BV1024-12VI 44J 40V Industrial (-40°C to 85°C) 8 0.02 AT27BV1024-15JC AT27BV1024-15VC 44J 40V Commercial (0°C to 70°C) 8 0.02 AT27BV1024-15JI AT27BV1024-15VI 44J 40V Industrial (-40°C to 85°C) 120 150 Package Type 44J 44-Lead, Plastic J-Leaded Chip Carrier (PLCC) 40V 40-Lead, Plastic Thin Small Outline Package (VSOP) 10 x 14 mm 10 AT27BV1024 Operation Range AT27BV1024 Packaging Information 44J, 44-Lead, Plastic J-Leaded Chip Carrier (PLCC) Dimensions in Inches and (Millimeters) JEDEC STANDARD MS-018 AC 40V, 40-Lead, Plastic Thin Small Outline Package (VSOP) Dimensions in Millimeters and (Inches) JEDEC OUTLINE MO-142 CA .045(1.14) X 45° PIN NO. 1 IDENTIFY .045(1.14) X 30° - 45° .012(.305) .008(.203) .630(16.0) .590(15.0) .656(16.7) SQ .650(16.5) .032(.813) .026(.660) .695(17.7) SQ .685(17.4) .050(1.27) TYP .500(12.7) REF SQ .021(.533) .013(.330) .043(1.09) .020(.508) .120(3.05) .090(2.29) .180(4.57) .165(4.19) .022(.559) X 45° MAX (3X) 11 Atmel Headquarters Atmel Operations Corporate Headquarters Atmel Colorado Springs 2325 Orchard Parkway San Jose, CA 95131 TEL (408) 441-0311 FAX (408) 487-2600 Europe 1150 E.
